How to Review Your Budget Every Month

A budget is a forecast, and forecasts go stale. The monthly review is what keeps yours connected to reality — and it takes about twenty minutes.

Compare plan against actual

Put your planned figures next to what actually happened, category by category. You are looking for variances above roughly ten percent; small differences are noise and not worth analysing.

Ask why, once, for each variance

  • Was the plan wrong, meaning the budget number needs to change?
  • Was it a one-off event that will not repeat?
  • Is it a pattern that has been building for several months?

Fix one thing, not everything

Choose the single largest problem category and address it for the coming month. Attempting to correct five categories at once reliably produces no change in any of them.

The 20-minute agenda

  1. Update your actual figures (5 minutes).
  2. Mark variances over ten percent (3 minutes).
  3. Note upcoming irregular costs for next month (5 minutes).
  4. Adjust next month's numbers (5 minutes).
  5. Confirm your savings transfer is still correct (2 minutes).

Track two numbers over time

Your savings rate and your total fixed costs. If the savings rate is rising and fixed costs are flat or falling, the plan is working regardless of how any single month felt.

Make it a fixed appointment

Same day each month, in the calendar, ideally just before payday. Reviews that depend on remembering do not happen.
