The plan replaces a rigid, inflation-adjusted withdrawal rule with a flexible spending process. Start with research on safe spending rates or use an adviser, then vary portfolio withdrawals with conditions: take more when markets and balances are up and somewhat less when they are down. Map unusual expenses, such as a major family trip, into the specific years when they are likely to occur rather than pretending spending will be level. The plan also recognises that retirement spending commonly declines with age, so healthy early retirement years can support more travel and family assistance. Revisit the plan annually to check what the portfolio can support and adjust the next year's spending.

Core principles

  • 01Treat spending as flexible rather than fixed
  • 02Spend more when markets and balances are strong
  • 03Expect spending needs to change with age
  • 04Plan exceptional outlays separately from recurring costs

How to run it

  1. 1

    Set a researched starting range

    Use safe-spending-rate research or work with a financial adviser to establish what the portfolio can reasonably distribute.

    Pro tip Treat the rate as a starting reference, not a permanent instruction.

    Watch out A four-percent-style guideline is not, by itself, a retirement spending plan.

  2. 2

    Map lumpy expenses

    Place major trips, family support, and other exceptional outlays into the years when they are expected. Keep them separate from recurring living costs.

    Pro tip Costing a desired trip can also turn it from a vague intention into an actionable plan.

  3. 3

    Front-load suitable experiences

    Allow more discretionary spending in healthy early retirement years when travel and other activities are easier. Account for evidence that household spending tends to fall with age.

    Pro tip Use the expected later decline as permission to fund meaningful early-retirement goals.

    Watch out Keep future healthcare and long-term-care uncertainty in the plan.

  4. 4

    Respond to market conditions

    Take more when markets and the portfolio balance are up, and take somewhat less when they are down. Preserve flexibility instead of forcing a straight-line withdrawal path.

    Watch out Do not assume markets or inflation will follow a predictable path.

  5. 5

    Reassess each year

    Review the withdrawal rate, the portfolio's supportable spending, and the coming year's planned outlays. Adjust the budget rather than setting it once and forgetting it.

    Pro tip Combine the spending review with portfolio maintenance and tax planning.

In the wild

A family trip in year two

A retiree plans a large family trip for the second year of retirement. Instead of adding its cost to every annual budget, the retiree estimates the trip's one-time effect on that year's withdrawals, then keeps later years lower and retains room to adjust if markets fall.

→ The trip becomes a funded, time-specific goal without distorting the entire retirement budget.

Common mistakes

Using one fixed rate forever

A straight-line withdrawal rule ignores lumpy spending, market changes, inflation, and the tendency for spending to decline with age.

Leaving goals vague

Uncosted travel or family plans remain aspirations and never become part of the retirement spending plan.

Preserving the high-water mark

Refusing to let the portfolio balance ever decline can cause a well-funded retiree to short-change their quality of life.

Is it for you?

Best for

It is best for retirees with invested assets who can vary discretionary spending from year to year.

Not ideal for

It is not ideal for households whose essential spending already consumes all guaranteed and portfolio income.
