The retirement budget: build it forward, not from a rule of thumb

Most retirement budgets start from a rule — "70% of pre-retirement income" — and end there. The version that works builds forward: real categories, real amounts, and dated lumpy years for travel, healthcare and the car. Then it tests the result against actual income sources.

  • Category-first

    Real lines: housing, food, healthcare, transport, travel, giving.

  • Dated lumpy years

    Travel, car and healthcare years are dated events, not averages.

  • Income test

    Pension plus withdrawals must cover the dated months.

  • 10% buffer

    The contingency line that makes the plan survive reality.

Building it

  1. List fixed costs: housing, utilities, insurance, taxes.
  2. Cost healthcare honestly — premiums plus a dated co-pay allowance.
  3. Add variable lines from your actual current spending.
  4. Add the lumpy years: travel, car replacement, home repair.
  5. Test monthly against pension and withdrawal income.

The two checks

Check one: does the monthly total fit the income? Check two: does the cash hold through the lumpy years? A budget that passes monthly but fails the car-replacement year is still a failing plan.

The calendar makes check two visible — project the full year and the dips appear before they happen.

Frequently asked questions

How much do I need to live on in retirement?

Build it from your real categories. Most retirees land at 70–85% of pre-retirement spending, but healthcare and travel years are where the estimates fail.

What do people forget in a retirement budget?

Healthcare inflation, car and home replacement cycles, travel years, and taxes on withdrawals — all dated events, not averages.

How is a retirement budget different from a working budget?

Fixed income replaces salary, healthcare costs rise, and lumpy events come faster. The structure — dated and tested — is identical.

When should I start building it?

Five years before retirement. The earlier the dated model exists, the more levers you still have.
