Example to load

Explore a regular withdrawal budget, including an estimated split between distributions and asset sales.

$600,000 portfolio; $2,000 monthly, increasing with 2.5% inflation; 5% assumed total return, 0.25% additional costs and 2% distribution yield; 30 years.

Inflation & additional assumptions · 2.5% inflation · 0% costs

Annual inflation

Used to express purchasing power in today’s dollars.

Additional annual costs

Set 0 if these costs are already included in your return assumption.

Estimated annual distribution yield

Optional funding split. Distributions are already included in total return and are not added again.

Downturn timing comparison · Optional

Compare early and late market drops

The comparison adds the same drop at the start or at the beginning of the final year. Both otherwise use the same return assumptions. Without withdrawals, the two drop paths have the same ending value. These are hypothetical paths, not historical returns or probabilities.

Withdrawal model assumptions

Monthly total returns include distributions. Additional costs are deducted proportionally before month-end withdrawals. Annual withdrawal budgets are divided by 12. Fixed spending can rise once per year with inflation; percentage spending resets from each year’s opening value. Distribution yield estimates how funded withdrawals are split between distributions and sales, without increasing total return. Unused distributions remain invested. The model caps withdrawals at available assets and tracks any shortfall. Results exclude taxes, account restrictions and random market paths.
