Your first budget in 4 steps

Your first budget doesn't need a spreadsheet with fifty rows. Four steps are enough to give every euro a job and see whether the plan holds up.

The four steps

Use the numbers you collected when you tracked a month of spending. If you haven't done that yet, start with your bank statements from last month.

  • Write down your take-home pay. Use what actually reaches your account each month, not your salary before tax.
  • List your fixed costs. Rent, utilities, insurance, transport passes, minimum debt payments and the monthly share of yearly bills.
  • Set your saving amount first. Decide what moves to savings on payday, before any other spending happens.
  • Give the rest a weekly limit. Whatever is left covers groceries, eating out and everything flexible. Split it into a weekly amount so you can check it as you go.

A worked example

Say you take home €1,800 a month. Your fixed costs come to €1,050 and you decide to save €150 on payday. That leaves €600 for flexible spending (1,800 − 1,050 − 150 = 600).

A month is a little longer than four weeks, so the fair weekly figure is €600 × 12 ÷ 52, which is about €138. If you spend €120 one week, the €18 left over can roll into the next week or go to savings.

The plan balances when income minus everything you have planned comes to zero: 1,800 − 1,050 − 150 − 600 = 0. Every euro has a job.

Review after one month

At the end of the first month, compare the plan with what really happened. Expect to adjust it – a grocery limit that was too tight or a bill you forgot is normal, not a failure.

Change one or two numbers and run the plan for another month. A budget you keep using and adjusting is worth more than a perfect one you give up on.

Make it automatic

Set up a standing order that moves your saving amount to a separate account on payday, and pay fixed bills by direct debit where you can. Then the only number you need to watch during the month is your weekly limit.

You may find it easier to move the weekly amount to a separate card or account at the start of each week. When it is gone, flexible spending stops until the next week begins.

Key takeaways

  • Start from take-home pay and fixed costs, then set saving before anything else.
  • Turn what's left into a weekly limit you can check as you go.
  • Expect to adjust the plan after the first month.

Try it

Opens the budget calculator with €1,800 of take-home pay, as in the example, so you can add your own fixed costs and saving.
