How to manage your budget without tracking every expense

A method in four steps, which lasts because it asks for very little.

What a budget is for

A bank statement tells you where last month's money went. A budget answers a different question: what you will have left in three months, in a year, if nothing changes — and what would change if something did. That question is what lets you see an expense coming, know whether a plan is affordable, or notice that your account is going down before it drops below zero.

Most methods fail for the same reason: they ask you to record every purchase. You keep it up for two weeks, then you forget one receipt, then ten, and the budget no longer tells you anything. The method below does the opposite: it records little, but it records it accurately.

1. Start from what you have

The starting point is a single figure: the total of your accounts today, savings included, with a negative balance entered as a minus. There is no need to go back over the past: a budget looks ahead.

2. Enter once what comes back every month

Your income, then your fixed expenses — the ones that come back whatever you do:

• rent or the monthly payment for your home;
• electricity, gas, water;
• insurance;
• broadband, phone, subscriptions;
• transport, everyday groceries.

An expense paid once a year is brought back to a monthly amount: insurance at €360 a year weighs 360 ÷ 12 = €30 per month. These lines almost never change: you write them once, and you only touch them again when they really change.

3. Keep some spending money

A coffee, a present, a taxi, an evening out: rather than recording each of these small expenses, set aside a fixed amount for them each month — your spending money. Everything that is neither a fixed expense nor planned comes out of it, and you have nothing left to record.

What remains after your fixed expenses and your spending money is what you set aside. For example, with €2,200 of income, €1,600 of fixed expenses and €150 of spending money: 2,200 − 1,600 − 150 = €450 set aside every month.

4. Check once a month

Once a month, enter the total of your accounts and compare it with what was planned. If you have less left than planned, it is almost always because your spending money is too tight: simply increase it. If you have more left, it is too generous. Within a few months, the budget matches your real life, without your having recorded a single receipt.

Plan for what only happens once

A repair, the start of the school year, a trip, a bonus: enter them in the month they fall. The budget then shows the dip or the bump they make, and you know in advance whether your account can absorb them.

What this method does not do

• It gives no advice. It describes your figures; it does not tell you what to do with your money, nor where to put it.
• It compares you with no one. No averages, no norms: only your own amounts.
• It does not predict the future. A projection assumes that your amounts stay the ones you entered; the monthly check puts it back on track.

The same method, calculated for you

Budgiva applies exactly these four steps: you enter your capital, your lines and your spending money, by hand or in one sentence to the AI agent, and it calculates what you will have left, month after month, up to five years ahead — with no bank connection. The getting-started guide shows it screen by screen.
