Build it in one sitting
- Collect recent bank statements, bills and payslips.
- Write down reliable net household income.
- List essential monthly costs.
- Convert annual and irregular bills to monthly set-asides.
- Add debt payments, savings and realistic discretionary spending.
- Subtract outgoings from income.
The CCPC recommends using real income and spending figures and provides a budget planner. See CCPC budgeting guidance.
If the result is negative, act in order
First check for missing income, duplicated costs or unrealistic estimates. Then protect housing, energy, food, medicine, work travel and required payments. Contact providers early about unaffordable bills rather than using new high-cost credit to conceal the gap.

Make the budget survive real life
- Use separate pots for annual bills and emergencies.
- Review after payday and before large direct debits.
- Give variable categories a limit, not a wish.
- Change the plan after income, rent, childcare or debt changes.
- Keep a small margin for timing and estimation errors.
