Zero-based budgeting: a free method that works
A zero-based budget means income minus planned spending, saving and debt payments equals zero. You haven't spent everything. Every euro simply has a job before the month starts.
The free method (pen and paper is fine)
- Write your take-home pay for the month. Use net pay, not salary. See our Ireland and UK guides.
- List fixed bills: rent or mortgage, utilities, phone, insurance, subscriptions.
- Add "sinking funds" for irregular costs: yearly bills like car tax and insurance divided by 12, plus Christmas and birthdays.
- Plan variable spending: groceries, fuel, eating out, fun money.
- Give the rest a job: emergency fund, extra debt payment, savings.
- Check it equals zero. If it's negative, cut a want. If it's positive, assign the leftover.
- Track as you go and move money between categories when life happens. Rebalancing is allowed.
Tips that make it stick
- Budget on payday, not on the 1st, if your pay dates move.
- Keep a small "miscellaneous" line so one forgotten item doesn't break the plan.
- Do a 10-minute review at the end of each month.
- The 50/30/20 rule (needs/wants/savings) is a handy sense check for your totals.
