How to fit yearly bills into a monthly budget

By Mesura Studio. Updated 6 November 2026. 3 min read.

Short answer

List every cost that does not come monthly, add them up and divide by 12. Move that amount into a separate savings pot each month. When a bill arrives, you pay it from the pot, and your normal monthly budget stays untouched.

An example

CostPer yearPer month
Home insurance€600€50
Car tax and service€240€20
Holidays€1,800€150
Total€2,640€220

Moving €220 a month covers all three, whenever they fall due.

How to set it up

  1. Check last year's bank statements for costs that came once or twice.
  2. Note each amount and the month it is due.
  3. Divide the total by 12 and set up an automatic transfer after payday.
  4. Pay those bills from the pot, and update the amounts when prices change.

Costs people often forget

  • Insurance, memberships and annual subscriptions
  • Local taxes and accountant fees
  • Birthdays, Christmas and other gifts
  • Car and home repairs

If your first bill is due soon

You may not have time to save the full amount. Save what you can for that bill, and let the monthly amount catch up during the year.

Common questions

Is this the same as a sinking fund?

Yes. A sinking fund is the usual name for money set aside each month for a known future cost.

Should this money be separate from my emergency fund?

Yes. Yearly bills are expected, while an emergency fund is for surprises.

What if I get paid a bonus?

A bonus or extra payslip can fill the pot at once, which lowers what you need to set aside each month.
