How to make a monthly budget in 7 steps

A budget is not there to forbid things. It is there so you decide in advance where your money goes, instead of finding out afterwards. These seven steps work whether you live alone, as a couple or with children.

1. Set concrete goals

"Save more" is not a goal, it is a wish. A goal says what, how much and by when: "build a €1,800 emergency fund in 12 months" or "pay off the credit card by June". With an amount and a deadline, you know how much to set aside each month.

2. Estimate your income cautiously

Use the take-home pay you are certain to receive. Bonuses, extra payments or gifts only count once they reach your account. If your income varies, start from the lowest amount of recent months.

3. Put savings and your emergency fund first

The most common mistake is saving whatever is left at the end of the month. Treat savings as a fixed expense: the first payment to leave when you get paid. Your emergency fund should reach three to six months of essential expenses, and more if your income is irregular.

4. List your fixed expenses

Rent or mortgage, loans, insurance, phone and internet, transport. Don't forget annual or twice-yearly bills, such as car insurance or property tax: divide them across the months and set that amount aside every month.

5. Give your variable expenses a limit

Food, eating out, fuel, leisure, clothes. Start from your average spending over recent months and adjust where you want to cut back. Allow for rising prices: what cost €300 two years ago probably doesn't cost the same today.

6. Track spending and compare it with the plan

The difference between what you planned and what you spent is called a variance. If you spent less, that category has a surplus. If you spent more, it has a deficit that has to come from another category or from savings.

Example: you planned €380 for groceries and spent €406. The variance is €26 over. If you planned €120 for leisure and spent €90, the €30 left over covers the difference.

7. Review the month and adjust

At the end of each month, look at the categories with variances. A category that goes over every month has an unrealistic limit: raise it and take the difference from another. Review your goals too, because life changes and your budget has to change with it.

What makes a budget work

• Realistic: a budget that is too tight gets abandoned within two weeks.
• Flexible: it has to cope with surprises and life changes.
• Written down: a budget kept only in your head is easily forgotten.
• Shared: if you live with someone, decide together.

In FinanceFlow, from the Pro plan up, each category or group of expenses can have a monthly or weekly limit, and the app warns you as you get close to it. On Premium, the AI suggests a limit for each category based on your income, fixed expenses and savings goal, and you adjust whatever you like before applying it.
