Safe withdrawal rate calculator for rate scenarios
A withdrawal rate is an initial portfolio-withdrawal assumption. Compare first-year amounts and consider how horizon, inflation, taxes, fees and spending flexibility affect a plan.
Illustrative initial withdrawal amounts per $1 million
| Initial-rate assumption | Year-one amount | Spending multiple |
|---|---|---|
| 3.0% | $30,000 | 33.3x |
| 3.5% | $35,000 | 28.6x |
| 4.0% | $40,000 | 25x |
| 4.5% | $45,000 | 22.2x |
| 5.0% | $50,000 | 20x |

What to consider across retirement horizons
- Time horizon: longer plans involve more years of uncertain returns and spending.
- Historical evidence: the Trinity Study tested periods up to 30 years. Read AAII's study summary; those results do not predict future outcomes.
- Portfolio assumptions: asset mix, fees, taxes, inflation and withdrawal timing affect outcomes.
- Spending flexibility: compare fixed and adjustable plans while considering how variable income would affect you.
Flexible vs fixed SWR
A fixed plan can raise a starting withdrawal with inflation, while a variable plan may adjust income as the portfolio changes. These approaches trade different levels of income stability and portfolio risk; their outcomes depend on the exact rules and inputs.

Methodology and editorial standards
Each calculator uses its own inputs and method. Review the labels, units and assumption notes shown with the result. Costs, taxes, fees, benefits and other factors are not modeled unless the page or calculator explicitly says they are. A fixed-rate projection is a scenario, not a forecast or personalized recommendation.
