Apuntar cada gasto a mano es donde la mayoría de los controles de gastos se quedan por el camino. El café, el supermercado, la gasolina: son pocos segundos cada vez, pero hay que acordarse siempre. Desde iOS 27, el iPhone puede hacer buena parte de ese trabajo por ti. Cada vez que pagas con Apple Pay, una automatización de la app Atajos abre tu app de gastos con el importe, el comercio y la fecha ya escritos. Tú solo confirmas.

Aquí verás cómo funciona el registro automático de gastos con Apple Pay, qué pagos recoge y cuáles no, y cómo configurarlo en abacova en tres pasos.

Qué significa “automático” en un control de gastos

Hay dos formas de que los gastos entren sin escribirlos uno a uno, y se complementan:

• Importar el archivo de tu banco. Una vez a la semana o al mes descargas el extracto y lo importas. Recoge todo lo que pasó por la cuenta, pero llega tarde: cuando lo revisas, ya no recuerdas qué era aquel cargo de 23,40 €.
• Registrar el gasto en el momento de pagar. El teléfono sabe que acabas de pagar, cuánto y dónde. Si en ese instante se abre la app con el gasto preparado, apuntarlo cuesta un toque, y lo haces cuando todavía sabes qué has comprado.

El registro automático con Apple Pay es la segunda forma. La importación bancaria sigue siendo útil para lo que no pasa por el móvil.

Cómo funciona con Apple Pay y Atajos

Atajos es la app de Apple para automatizar tareas en el iPhone. En iOS 27, las automatizaciones viven dentro de los atajos: un atajo puede llevar un disparador que lo pone en marcha solo.

Uno de esos disparadores es de la app Cartera: “Cuando acerco una tarjeta de pago o pase de la app Cartera”. Cuando pagas con una tarjeta guardada en Cartera, iOS pasa al atajo el importe, el comercio y la tarjeta que has usado. El atajo de abacova toma esos datos y abre la app con un gasto nuevo ya rellenado.

Lo que pasa después:

1. La primera vez que pagas con una tarjeta, abacova te pregunta de qué cuenta sale y lo recuerda para los siguientes pagos.
2. Revisas el gasto, eliges la categoría si quieres y lo guardas. Se crea como movimiento pendiente.
3. Si cierras sin guardar, el pago no se pierde: espera en una lista de Pagos por confirmar, detrás de una campanita en Movimientos, para confirmarlo o descartarlo después. Conserva el día del pago.

Qué se registra y qué no

Apple Pay dentro de apps y de webs puede activar la automatización o no: no lo garantizamos.

Configurarlo en abacova: tres pasos

Solo se hace una vez, en el iPhone con la app de abacova instalada:

1. Abre Más → Registro automático de gastos y pulsa “Añadir el atajo de abacova”. En Atajos, pulsa “Añadir atajo”. La automatización viene incluida.
2. En Atajos, abre Automatización y activa “Cuando acerco una tarjeta de pago o pase de la app Cartera”. Llega desactivada, así que este paso es imprescindible.
3. Paga algo con Apple Pay: abacova se abre con el gasto ya rellenado.

Si el iPhone tiene una versión anterior a iOS 27, la app te lo dice y te pide actualizar en Ajustes → General → Actualización de software.

Efectivo, Bizum y lo demás: toque en la parte trasera

Para lo que no pasa por Apple Pay, el iPhone tiene otro truco. Con el atajo “New expense in abacova”, un doble toque en la parte trasera del teléfono abre un gasto nuevo en blanco, sin buscar la app ni navegar por menús.

1. En la misma pantalla de abacova, pulsa “Añadir el atajo de gasto nuevo”.
2. En Ajustes del iPhone: Accesibilidad → Tocar → Toque posterior → Toque doble.
3. Selecciona el atajo “New expense in abacova”.

Funciona con el iPhone desbloqueado.

Límites que conviene conocer

• Necesita iOS 27 o posterior. Está probado en iOS 27.
• Si pagas desde la pantalla de bloqueo, iOS pide desbloquear antes de abrir abacova.
• Si tienes activado el bloqueo por Face ID de abacova, primero se pide Face ID.
• Guardar un movimiento necesita conexión. Mientras tanto, el pago espera en Pagos por confirmar (hasta 50).
• En Android todavía no está disponible. Llegará pronto.

Privacidad

No se conecta ningún banco y no compartes ninguna contraseña. El atajo funciona en tu iPhone, y nada sobre un pago sale del teléfono hasta que lo guardas. abacova no tiene anuncios ni rastreadores y no vende datos.

Preguntas frecuentes

¿Tengo que escribir algo en cada pago? No. El importe, el comercio y la fecha llegan rellenados. Solo confirmas, y si quieres eliges la categoría.

¿Qué pasa si no quiero guardar un pago? Lo descartas en Pagos por confirmar y no se crea ningún movimiento.

¿Tengo que dar la contraseña de mi banco? No. Todo sale de tu propio iPhone, en el momento de pagar.

¿Cuánto cuesta? Los pagos que guardas son movimientos normales. El plan gratuito no pide tarjeta e incluye dos cuentas y 200 movimientos al mes. En la página de precios puedes ver qué incluye cada plan.

¿Sustituye a importar el extracto? No del todo. Recoge lo que pagas con Apple Pay, que para mucha gente es buena parte del día a día. Para el resto, el extracto completa el mes. Si aún estás eligiendo herramienta, estas siete preguntas para elegir una app de gastos te ayudan, y separar gastos fijos y variables te dice dónde mirar primero.

Typing in every expense is where most expense trackers fall by the wayside. A coffee, the weekly shop, a tank of fuel: each takes a few seconds, but you have to remember every time. Since iOS 27, your iPhone can do much of that work for you. Each time you pay with Apple Pay, an automation in the Shortcuts app opens your expense tracker with the amount, the merchant and the date already filled in. All you do is confirm.

This guide explains how automatic expense tracking with Apple Pay works, which payments it picks up and which it doesn’t, and how to set it up in abacova in three steps.

What “automatic” can mean for an expense tracker

There are two ways to get expenses in without typing them one by one, and they work well together:

• Importing your bank’s file. Once a week or once a month you download your statement and import it. It catches everything that went through the account, but it arrives late: by the time you review it, you no longer remember what that 23.40 charge was.
• Recording the expense as you pay. Your phone knows you have just paid, how much and where. If your app opens at that moment with the expense ready, logging it takes one tap, and you do it while you still know what you bought.

Automatic capture with Apple Pay is the second kind. Importing your bank’s file is still useful for everything that doesn’t go through your phone.

How it works with Apple Pay and Shortcuts

Shortcuts is Apple’s app for automating tasks on the iPhone. In iOS 27, automations live inside shortcuts: a shortcut can carry a trigger that starts it on its own.

One of those triggers comes from the Wallet app: “When I tap a Wallet pass or payment card”. When you pay with a card stored in Wallet, iOS hands the shortcut the amount, the merchant and the card you used. The abacova shortcut takes those details and opens the app with a new expense already filled in.

What happens next:

1. The first time you pay with a card, abacova asks which account it pays from and remembers it for the next payments.
2. You check the expense, pick a category if you like, and save it. It is created as a pending transaction.
3. If you close without saving, the payment isn’t lost: it waits in a Payments to confirm list, behind a bell on Transactions, for you to confirm or discard later. It keeps the day you paid.

What is recorded and what isn’t

Apple Pay inside apps and on websites may or may not fire the automation: we don’t promise it does.

Setting it up in abacova: three steps

You do this once, on the iPhone with the abacova app installed:

1. Open More → Automatic expense capture and tap “Add the abacova shortcut”, then “Add Shortcut” in Shortcuts. The automation comes with it.
2. In Shortcuts, open Automation and switch on “When I tap a Wallet pass or payment card”. It arrives switched off, so don’t skip this step.
3. Pay for something with Apple Pay: abacova opens with the expense filled in.

If your iPhone runs a version older than iOS 27, the app tells you and asks you to update in Settings → General → Software Update.

Cash and everything else: Back Tap

For whatever doesn’t go through Apple Pay, the iPhone has another trick. With the “New expense in abacova” shortcut, a double tap on the back of the phone opens a blank new expense, with no hunting for the app or tapping through menus.

1. On the same abacova screen, tap “Add the new expense shortcut”.
2. In the iPhone’s Settings: Accessibility → Touch → Back Tap → Double Tap.
3. Select the “New expense in abacova” shortcut.

It works while the iPhone is unlocked.

Limits worth knowing

• It needs iOS 27 or later, and it has been tested on iOS 27.
• If you pay from the lock screen, iOS asks you to unlock before abacova opens.
• If abacova’s Face ID lock is on, Face ID is asked for first.
• Saving a transaction needs a connection. Until then, the payment waits in Payments to confirm (up to 50).
• It isn’t available on Android yet. It is coming soon.

Privacy

No bank is connected and you share no password. The shortcut runs on your iPhone, and nothing about a payment leaves the phone until you save it. abacova has no ads and no trackers, and it doesn’t sell data.

Frequently asked questions

Do I have to type anything for each payment? No. The amount, the merchant and the date arrive filled in. You confirm, and choose a category if you want to.

What if I don’t want to keep a payment? Discard it in Payments to confirm and no transaction is created.

Do I have to give it my bank password? No. Everything comes from your own iPhone, at the moment you pay.

How much does it cost? The payments you save are ordinary transactions. The free plan needs no card and includes two accounts and 200 transactions a month. The pricing page shows what each plan includes.

Does it replace importing my statement? Not entirely. It records what you pay with Apple Pay, which for many people is a good part of everyday spending. Your statement fills in the rest of the month. If you are still choosing a tool, these seven questions for choosing an expense tracker app will help, and splitting fixed and variable expenses shows you where to look first.

Double-entry bookkeeping, also called double-entry accounting, is a method in which every transaction is recorded twice: once in the account the value leaves and once in the account it reaches. It rests on a very simple idea: money doesn’t appear or vanish. It always comes from somewhere and goes somewhere.

It isn’t new. The friar and mathematician Luca Pacioli described it in 1494 in his Summa de arithmetica, based on what Italian merchants were already doing, and it is still the basis of accounting today.

How it differs from a list of expenses

With an ordinary list, known as single-entry, buying something for 60 is one line: “food, 60”. That tells you what you spent on, but not where the money came from.

Double entry records both sides at once: your food expense goes up and your bank balance goes down. Every transaction leaves a complete trail, which is why it can be checked.

Debits and credits

Each entry has two sides, called debit and credit. They don’t mean “good” or “bad”, and a credit isn’t always money coming in. They are simply the left and right columns of an account. The rule is this:

And the golden rule: in every transaction, total debits equal total credits.

Four everyday examples

1. You receive your pay of 2,000. Your bank balance goes up, and that increase comes from income.

2. You buy 60 of groceries with a debit card. The money leaves the bank and goes to an expense.

3. You eat out for 40 on a credit card. No money has left the bank yet: you have an expense and a new debt.

4. You pay off the 40 on the card. This is often the example that makes it click. It isn’t a new expense, because the expense was recorded with the dinner. The debt goes down and the bank goes down.

Add up all four transactions and debits and credits each come to 2,140. That is what makes the method useful: if the two columns don’t match, you know there is a mistake.

The numbers also fit together. The bank ends on 1,900, the card on zero, and your income of 2,000 minus your expenses of 100 also gives 1,900.

Why it matters for household money

A household doesn’t need to keep a formal ledger, but the method solves problems anyone can run into:

• A card payment isn’t counted twice. On a simple list it’s easy to record the purchase and then the payment too, which doubles the expense.
• A transfer isn’t an expense. Moving money to savings changes where it sits, not how much you have.
• Your net worth follows naturally. If you record assets and debts, what you own minus what you owe is a result, not a separate calculation.
• Mistakes can be found. When something doesn’t add up, there is a place to look.

Do you need to know accounting to use it?

Not necessarily. You can build it in a spreadsheet with three columns (account, debit and credit), but it takes discipline: each transaction needs two lines, and you have to know which side each one goes on.

Abacova keeps its books with double-entry bookkeeping, the method accountants use, but you don’t have to think in debits and credits. When you add a transaction you choose whether it is an expense, income or a transfer, and transfers between your own accounts count as neither expense nor income. To see how it is set up, the lesson on accounts and balances walks through it step by step.

Where to go next

To apply this to everyday life without the technical terms, start with our guide to personal bookkeeping.

Your net worth is what you own minus what you owe. If you sold everything you have tomorrow and paid off all your debts, it’s the money you would be left with. A net worth tracker is simply a way of recording that number over time. It’s the figure that best sums up your finances, because it sees something your bank balance doesn’t: someone with plenty in the bank and a larger debt can be worse off than someone with little and no debt.

The formula fits on one line:

Net worth = assets − debts

The work is in making the list complete. Here are the steps.

Take a snapshot of one specific day, such as the last day of the month. Every figure should be from that date, because balances and values change. If you always repeat the exercise on the same day, you can compare the results.

Step 2: add up your assets

An asset is anything that has value and could be turned into money. The usual list includes:

• Cash and accounts: everyday and savings accounts, and cash.
• Investments: shares, funds, pensions and retirement accounts.
• Property: your home and any other property, at what you could sell it for today, not what you paid.
• Vehicles: at their current resale value, which is usually well below the purchase price.
• Money you are owed: if someone is really going to pay it back.

Leave out everyday items such as furniture, clothes and appliances. They are hard to sell for what you think they are worth, and they only inflate the number.

Step 3: add up your debts

A debt is anything you would have to repay. Use today’s outstanding balance, not the monthly payment:

• mortgage;
• personal and car loans;
• credit card balances;
• purchases on instalments;
• money you owe friends or family.

Step 4: subtract

Here is a made-up example with round numbers:

What to do with the result

If the number is low, or even negative, it isn’t a verdict. That is very common early in a working life or just after buying a home. The number doesn’t tell you whether you’re doing well or badly. What matters is the direction.

That’s why it isn’t worth comparing yourself with other people’s averages. Compare yourself with you a few months ago. If your net worth is going up, you are on track, even if the number is still small.

There are two ways to grow it: increase your assets by saving and investing, and reduce your debts. Paying 200 off a loan improves your net worth just as much as saving 200.

Notice, too, what changes nothing. Moving money from your everyday account to savings doesn’t alter your net worth: it only changes where the money sits. Paying off a credit card doesn’t either, because your balance and your debt fall by the same amount.

Once a month or once a quarter is enough. Checking it daily adds nothing, especially if you hold investments whose value goes up and down. If you aren’t sure whether your pace is reasonable, start by working out how much to save each month.

How to track it without rebuilding the list

You can keep a net worth tracker in a spreadsheet: one row per asset or debt and one column per date. It works, as long as you update every balance by hand each time.

In abacova, balances come from your transactions, so you don’t have to copy them across. You create one account for each place you keep money, and the dashboard shows your net worth, how it has changed and an Assets vs debts card. The net worth report goes into more detail, and reports are available on every plan, including the free one. The investments section follows shares, funds and other assets with their valuation, although it isn’t part of the free or entry plans. You can compare them on the pricing page.

Where to start

Set aside half an hour, take today’s date and make the list with approximate numbers. A reasonable estimate is far better than none. Write it down, repeat the exercise in a few months and compare.

Tu patrimonio neto es lo que tienes menos lo que debes. Si mañana vendieras todo lo que posees y pagaras todas tus deudas, sería el dinero que te quedaría. Es la cifra que mejor resume tu situación financiera, porque tiene en cuenta algo que el saldo de tu cuenta no ve: una persona con mucho en el banco y una deuda mayor puede estar peor que otra con poco y sin deudas.

La fórmula cabe en una línea:

Patrimonio neto = activos − deudas

Lo laborioso es hacer la lista completa. Estos son los pasos.

Paso 1: elige una fecha

Toma una foto de un día concreto, por ejemplo el último del mes. Todas las cifras deben ser de esa fecha, porque los saldos y los valores cambian. Si repites la cuenta siempre el mismo día, podrás comparar los resultados.

Paso 2: suma tus activos

Un activo es todo lo que tiene valor y podrías convertir en dinero. Lo habitual es incluir:

• Efectivo y cuentas: cuentas corrientes, de ahorro y dinero en efectivo.
• Inversiones: acciones, fondos, planes de pensiones.
• Inmuebles: tu vivienda y cualquier otra propiedad, por el precio al que podrías venderlos hoy, no por lo que pagaste.
• Vehículos: por su valor actual de reventa, que suele ser bastante menor que el de compra.
• Dinero que te deben: si alguien va a devolvértelo de verdad.

No incluyas objetos del día a día, como muebles, ropa o electrodomésticos. Es difícil venderlos por lo que crees que valen, y solo sirven para inflar la cifra.

Paso 3: suma tus deudas

Una deuda es todo lo que tendrías que devolver. Usa el saldo pendiente hoy, no la cuota mensual:

• hipoteca;
• préstamos personales y del coche;
• saldo de las tarjetas de crédito;
• compras a plazos;
• dinero que debas a amigos o familiares.

Paso 4: resta

Un ejemplo inventado, con cifras redondas:

Qué hacer con el resultado

Si la cifra sale baja, o incluso negativa, no es un veredicto. Es muy común al empezar la vida laboral o justo después de comprar una vivienda. La cifra no te dice si lo estás haciendo bien o mal. Lo que importa es la dirección.

Por eso no merece la pena compararte con las medias de otras personas, sino contigo mismo hace unos meses. Si tu patrimonio neto sube, vas bien, aunque el número aún sea pequeño.

Hay dos formas de hacerlo crecer: que aumenten tus activos, ahorrando e invirtiendo, y que bajen tus deudas. Pagar 200 € de un préstamo mejora tu patrimonio neto igual que ahorrar 200 €.

Fíjate también en lo que no cambia nada. Pasar dinero de la cuenta corriente a la de ahorro no modifica tu patrimonio neto: solo cambia el sitio donde está. Y pagar la tarjeta tampoco, porque bajan por igual tu saldo y tu deuda.

Cada cuánto calcularlo

Una vez al mes o al trimestre es suficiente. Mirarlo cada día no aporta nada, sobre todo si tienes inversiones cuyo valor sube y baja. Si no sabes si tu ritmo es razonable, empieza por calcular cuánto ahorrar al mes.

Cómo llevarlo sin rehacer la lista

Puedes llevarlo en una hoja de cálculo: una fila por activo o deuda y una columna por fecha. Funciona, siempre que actualices todos los saldos a mano cada vez.

En abacova, los saldos salen de tus movimientos, así que no tienes que copiarlos. Creas una cuenta por cada sitio donde tienes dinero, y el panel muestra el patrimonio neto, su variación y una tarjeta de activos frente a deudas. El informe de patrimonio neto lo muestra con más detalle, y los informes están en todos los planes, incluido el gratuito. La sección de inversiones sigue acciones, fondos y otros activos con su valoración, aunque no forma parte de los planes gratuito y de entrada. Puedes compararlos en la página de precios.

Por dónde empezar

Reserva media hora, elige la fecha de hoy y haz la lista con cifras aproximadas. Una estimación razonable es mucho mejor que no tener ninguna. Apúntala, repite la cuenta dentro de unos meses y compara.

There is no single right way to manage money as a couple. Some couples pool everything, others keep it separate and many do something in between. What works is what you both understand, feel is fair and can keep up. This article explains the three most common arrangements and how to choose, without assuming one is better than the others.

Before you decide: the conversation

Before you open any account, it helps to talk about four things:

• What comes in. Each person’s income, and whether it’s stable.
• What’s owed. Loans, cards and any existing debt. Better to know today than to find out later.
• What you want. Shared and personal goals: a home, a trip, a career change.
• What worries you. One person may need a bigger cushion to feel calm, and the other may feel watched if they have to justify every purchase. Neither is wrong.

It helps to talk with the numbers in front of you and to choose a calm moment, not the middle of an argument about one purchase.

1. Everything together. Both incomes go into a joint account and everything is paid from there. It’s simple and reinforces the idea of a team. In exchange, every personal purchase is visible, which can cause tension if your habits are very different.

2. Everything separate. Each person keeps their own money and splits shared costs as agreed. It preserves independence, but you need to keep track of who paid for what, and it works less well with unequal incomes.

3. A joint account plus personal accounts. Each person pays into a joint account for household costs and keeps the rest. It’s a middle ground: openness on what’s shared and freedom on what’s personal.

50/50 or proportional

If you choose the third option, one decision remains: how much each of you pays in. With similar incomes, half each is usually enough. With different incomes, many couples prefer to contribute in proportion.

Here is an example with made-up numbers. One person takes home 3,600 and the other 2,400, and shared costs are 3,000:

With a 50/50 split, each would pay 1,500: person A would have 2,100 left and person B, 900. Neither approach is right by definition. What matters is that the decision is explicit and that you are both comfortable with the result.

That line causes more conflict than the percentages do. Housing, utilities, groceries and children’s costs usually count as shared. Cars, entertainment and gifts vary from couple to couple. Also agree an amount above which you’d rather check with each other before buying. It doesn’t need to be high. It heads off a lot of surprises.

And keep some money for each of you with no questions asked, however little.

A monthly review

Set aside half an hour a month. Three questions are enough: How did this month go? What’s coming next month? Are we on track for what we wanted? If you review often, money becomes something you handle together.

Use it to decide how much to save each month between you, and revisit your split if your incomes change.

How to keep it from falling on one person

It’s easy for one person to end up keeping the books while the other has no idea how things stand. A shared spreadsheet is a simple solution if you keep it up.

In abacova you can share the same accounts by inviting the other person into your organization, so you both see the same numbers. The free plan is for a single person, so sharing needs a paid plan; how many people can join depends on the plan, as the pricing page explains. If you’d rather each keep your own money separate, debts and shared expenses record who paid for what and keep a running balance per person, and you can settle up whenever you like, in full or in part.

Where to start

Pick an evening and share three numbers: what comes in, what you owe and what you pay each month in shared costs. That’s enough to try one arrangement for three months and then review it. If it doesn’t suit you, change it. To sort out the rest, our guide to personal bookkeeping is a good next step.

An emergency fund is money you set aside for costs you can’t predict: a breakdown, a medical bill, a month without income. It isn’t for a trip or an opportunity. It has one job: to stop an unexpected cost from forcing you to take out a loan, lean on a credit card or sell an investment at a bad moment.

What sets it apart from ordinary saving is its purpose. Saving goes towards something you want. An emergency fund is for what you hope won’t happen, and ideally you never touch it.

How much you need

A common guideline is three to six months of essential expenses. Notice that it’s expenses, not income, and only the essential ones: housing, utilities, food, insurance, transport and minimum debt payments.

To work out your number:

1. Add up what you would pay in a month if you cut everything that isn’t essential.
2. Multiply by three for the minimum and by six for the full target.

Here is an example with made-up numbers: with essential expenses of 1,800 a month, your fund would be between 5,400 and 10,800.

Three months or six

Aim closer to three months if you have a stable job, a second income in the household and few people depending on you. Aim for six or more if you work for yourself, your income is irregular, your industry is unstable or one income supports the household.

If those numbers feel far away, don’t be discouraged. Even a few hundred covers many repairs and stops the first surprise from landing on a credit card.

Where to keep it

There are three conditions: it should be safe, available at short notice and separate from your everyday money. A savings account apart from your main one is usually the simplest option. If it pays some interest, so much the better, but returns aren’t the point.

Don’t invest it in the stock market. An emergency can coincide with a bad spell for markets, and you would have to sell at the worst time. Don’t leave it in your everyday account either: if you can see it, it will get spent.

How to build it, step by step

1. Set a small first target. For example, one month of essential expenses. It’s more achievable than six months and already gives real protection.

2. Decide on a monthly amount. Divide the target by the number of months you want it to take. At 300 a month, you would reach 5,400 in 18 months.

3. Automate it. Schedule a transfer for the day after you get paid. If you have to decide every month, some months it won’t happen.

4. Use extra income. Bonuses, tax refunds or one-off money speed things up considerably.

5. Balance it with debt. If you have expensive debt, build a small cushion first, then focus on repaying. Afterwards, go back and finish the fund.

If you aren’t sure where the money will come from, review your fixed and variable expenses. To fit it in with your other goals, read how much to save each month.

When to use it

Before you touch it, ask three questions: Is it unexpected? Is it necessary? Is it urgent? If all three answers are yes, that’s what it’s for. A broken heater qualifies. A sale doesn’t. Nor does annual insurance, because you knew it was coming: for those costs, set money aside separately.

Using it isn’t a failure. It’s exactly what is supposed to happen. Afterwards, all that matters is filling it back up.

How to tell if you’re on track

What you want to know isn’t how much is in it, but how many months it covers. That number goes up when you save and down when your expenses rise.

In a spreadsheet, just divide the fund’s balance by your essential monthly expenses. Abacova has a dashboard card, Months of cover, that works out how long the money in your everyday, savings and cash accounts would last at your average monthly spending. Abacova has no dedicated emergency fund feature, and that card counts all of those accounts, not only the fund, against your average spending, not only the essentials. Even so, it’s a good guide, and creating a separate account for the fund lets you see its balance at a glance. Transfers between your own accounts don’t count as expenses.

Where to start

Work out your essential expenses for one month today, and open or choose a separate account. Schedule a transfer, even a small one. What matters is starting: a modest fund is better than none.

La partida doble es el método de contabilidad en el que cada movimiento se anota dos veces: una en la cuenta de la que sale el valor y otra en la cuenta a la que llega. Se apoya en una idea muy simple: el dinero no aparece ni desaparece, siempre viene de algún sitio y va a algún otro.

No es nuevo. El fraile y matemático Luca Pacioli lo describió en 1494 en su Summa de arithmetica, a partir de lo que ya hacían los comerciantes italianos, y sigue siendo la base de la contabilidad actual.

La diferencia con una lista de gastos

Con una lista normal, llamada partida simple, comprar algo de 60 € es una sola línea: “comida, 60 €”. Eso te dice en qué gastaste, pero no de dónde salió el dinero.

La partida doble recoge las dos caras a la vez: aumenta el gasto en comida y baja el saldo del banco. Cada operación deja un rastro completo, y por eso se puede comprobar.

Debe y haber

Cada anotación tiene dos lados, llamados debe y haber. No significan “bueno” ni “malo”, ni tampoco lo que deberías. Son solo la columna izquierda y la derecha de una cuenta. La regla es esta:

Y la regla de oro: en cada operación, lo anotado en el debe es igual a lo anotado en el haber.

Cuatro ejemplos de la vida diaria

1. Cobras tu nómina de 2.000 €. El banco aumenta, y ese aumento viene de un ingreso.

2. Haces la compra por 60 € con la tarjeta de débito. El dinero sale del banco y va a un gasto.

3. Cenas fuera por 40 € con la tarjeta de crédito. Todavía no ha salido dinero del banco: tienes un gasto y una deuda nueva.

4. Pagas los 40 € de la tarjeta. Este suele ser el ejemplo que más aclara. No es un gasto nuevo, porque el gasto ya se anotó en la cena. Baja la deuda y baja el banco.

Si sumas las cuatro operaciones, el debe y el haber dan 2.140 € cada uno. Ahí está la utilidad del método: si las dos columnas no coinciden, sabes que hay un error.

Y las cifras encajan entre sí. El banco queda en 1.900 €, la tarjeta en cero, y tus ingresos de 2.000 € menos tus gastos de 100 € dan también 1.900 €.

Por qué importa en las cuentas de casa

Una familia no necesita llevar un libro diario, pero el método resuelve problemas que cualquiera puede tener:

• El pago de la tarjeta no se cuenta dos veces. En una lista simple es fácil apuntar la compra y luego también el pago, y duplicar el gasto.
• Una transferencia no es un gasto. Mover dinero al ahorro cambia dónde está, no cuánto tienes.
• Tu patrimonio neto sale solo. Si registras activos y deudas, lo que tienes menos lo que debes es una consecuencia, no una cuenta aparte.
• Los errores se pueden encontrar. Cuando algo no cuadra, hay un sitio donde buscar.

¿Hay que saber contabilidad para usarla?

No necesariamente. Puedes montarla en una hoja de cálculo con tres columnas (cuenta, debe y haber), pero exige disciplina: cada operación necesita dos líneas y tienes que saber qué lado toca.

Abacova lleva sus libros por partida doble, el método que usan los contables, pero tú no tienes que pensar en debe y haber. Al crear un movimiento eliges si es un gasto, un ingreso o una transferencia, y las transferencias entre tus cuentas no cuentan como gasto ni como ingreso. Si quieres ver cómo se organiza, la lección sobre cuentas y libro mayor lo explica paso a paso.

Fixed expenses are the ones you pay every month for the same or nearly the same amount, such as rent. Variable expenses change from month to month depending on what you do, such as groceries or going out. Separating them is one of the first steps to understanding your money, because it shows which part of your budget is committed before the month begins and which part depends on your choices.

Examples of fixed expenses

They share two traits: they repeat regularly and the amount barely changes. The most common are:

• rent or mortgage;
• insurance;
• loan payments;
• subscriptions, gym, phone and internet plans;
• childcare or school fees.

Examples of variable expenses

The amount depends on use or on your decisions:

The unclear cases

Not everything fits. Electricity, water and gas are paid every month, but the amount changes: these are semi-fixed, also called semi-variable, expenses. Treat them as fixed in your plan, using an average amount, and review it from time to time.

Then there are irregular expenses: payments you know about in advance but that don’t arrive every month, such as annual insurance, property charges or car servicing. These are the ones that tend to derail a budget, because they feel like surprises when they aren’t. The fix is simple: divide the annual amount by twelve and set that aside every month.

An example with made-up numbers: a 360 annual insurance bill equals 30 a month. If you set that aside, the bill doesn’t upset that month.

Why it helps to separate them

It shows how much room you have. Subtract your fixed expenses from your income and the result is what’s left for variable expenses and savings. On a take-home income of 3,000 with 1,700 of fixed expenses, you have 1,300 left.

It tells you where to act. The two types come down in different ways.

It shows your risk. The bigger the fixed part, the less room you have if income falls, because those payments keep coming.

Bear in mind that fixed doesn’t mean essential: a subscription is fixed but not essential, while food is variable but essential. That’s why this split complements the 50/30/20 rule, which separates needs from wants.

How to reduce each type

Fixed expenses are cut once, and the saving repeats every month with no more effort. Once a year, review:

• subscriptions you no longer use;
• your phone, internet and energy plans;
• insurance, comparing prices at renewal;
• the terms of your mortgage or loans.

Variable expenses depend on habits, so they take more persistence. It helps to set a monthly amount for the big categories, shop with a list and wait a day before an unplanned purchase.

If you have to choose where to start, start with fixed expenses: they take only one decision.

How to keep track

To make this split you need to see a real month. Take your statement, mark each transaction as fixed or variable and add up each group. You can do it in a spreadsheet: our guide to setting up an expense tracker has the steps.

In abacova, fixed expenses fit naturally as planned transactions: you enter the rent, the subscription or your pay, and they can post automatically on their date or wait for your confirmation. They feed the cash-flow forecast, which projects your balances and warns you if an account would go negative. For variable expenses, categories and rules keep what comes in sorted, and the dashboard’s Spending pace card compares this month’s spending so far with last month at the same day.

Where to start

Take last month and make two lists. Add them up and work out what share of your income goes on fixed expenses. That percentage shows how much room you really have, and from there you can decide how much to save each month.

La conciliación bancaria consiste en comparar tus propios registros con el extracto del banco para comprobar que coinciden y explicar cualquier diferencia. Se asocia con las empresas, donde es una tarea habitual de contabilidad, pero el método es el mismo si llevas las cuentas de casa o de un pequeño negocio: dos versiones de la misma historia que deberían cuadrar.

Es importante porque tu saldo no sirve de mucho si no puedes fiarte de él. Si tus cifras dicen 1.000 € y el banco dice otra cosa, cualquier decisión que tomes con ese número parte de una base equivocada.

Por qué no coinciden nunca a la primera

Que haya diferencias es normal y no significa que hayas hecho algo mal. Las causas más habituales son:

• Desfases de fechas. Anotaste un pago el lunes y el banco lo cargó el miércoles.
• Comisiones e intereses. El banco los aplica y nadie te avisa.
• Olvidos. Una compra con tarjeta o un bizum que no llegaste a registrar.
• Duplicados. El mismo gasto anotado dos veces.
• Errores de importe. Un 45 que se convierte en 54.
• Cargos que no reconoces. Son los más importantes, porque pueden ser un error del banco o un uso indebido de tu tarjeta.

Cómo hacerla, paso a paso

1. Elige una fecha de corte. Lo más fácil es usar la fecha de cierre del extracto o el último día del mes.

2. Anota los dos saldos. El del extracto en esa fecha y el de tus registros en esa misma fecha.

3. Marca lo que coincide. Recorre el extracto y marca cada movimiento que aparezca también en tus registros, por importe y fecha aproximada.

4. Estudia lo que queda sin marcar. Lo que está en el banco y no en tus registros suele ser un olvido o una comisión. Lo que está en tus registros y no en el banco suele ser un desfase o un duplicado.

5. Corrige tus registros. Añade lo que falte, y borra o arregla lo que esté mal. Lo que aún no ha llegado al banco se queda como pendiente para la próxima vez.

6. Comprueba que la diferencia es cero y cierra el periodo. Lo cerrado no se vuelve a tocar: la próxima conciliación empieza donde acabó esta.

Cuando la diferencia no aparece

Unos trucos cuando algo no cuadra:

• Busca el importe exacto de la diferencia. A menudo es un movimiento concreto.
• Busca la mitad de la diferencia. Puede ser un gasto anotado como ingreso, que descuadra el doble de su importe.
• Si la diferencia es divisible entre 9, quizá hayas intercambiado dos cifras: un 45 por un 54 da una diferencia de 9.
• Revisa el saldo inicial. Si la conciliación anterior quedó mal, el error viene arrastrado.

Una diferencia muy pequeña se puede ajustar con una anotación explícita si después de buscar no la encuentras. Eso sí, como último recurso. Mejor una línea que diga “ajuste” que un número que finge cuadrar.

Cada cuánto hacerla

Una vez al mes, cuando llegue el extracto, es lo más práctico. Cuanto más tiempo dejes pasar, más difícil es recordar qué fue cada cargo.

Cómo hacerla sin tanto trabajo

Se puede hacer en papel o en una hoja de cálculo, y es un buen ejercicio la primera vez. Lo que cansa es marcar línea a línea y comprobar la suma.

Abacova tiene una sección propia de conciliación en la versión web. Importas el archivo de tu banco, indicas el saldo del extracto y marcas los movimientos, y la pantalla muestra la diferencia en verde cuando llega a cero. Puedes añadir lo que falte sobre la marcha y, si un cargo se ha asentado después del cierre, cambiar su fecha para que pase a la siguiente conciliación. Al finalizar, los movimientos quedan bloqueados, y la opción de ajustar la diferencia está ahí como último recurso.

Si quieres situar esto dentro de una rutina más amplia, nuestra guía de contabilidad doméstica la explica, y si tu problema es un número que no entiendes, lee un saldo que no sabes explicar.

Por dónde empezar

Coge el último extracto de tu cuenta principal y haz solo esa cuenta y ese mes. La primera conciliación es la más lenta. Después de esa, cada mes parte de un saldo en el que ya confías.
