What's your retirement number?

Flip your spending into the target portfolio: at a 4% withdrawal rate you need 25× annual expenses. Conservative? 33× at 3%. This tool shows the whole range.

25× (4% SWR)
30× (~3.3% SWR)
33× (3% SWR)
Annual income from $1M at 4%
Where does 25× come from? Safe withdrawal rate 4% → portfolio = spending ÷ 0.04 = 25 × spending. A $50,000 lifestyle needs $1.25M. It assumes a 30-year horizon and a 60/40-ish portfolio balanced across stocks and bonds.
Why consider 30× or 33×? Longer horizons (40–50 years for early retirees) and low historical bond yields argue for ~3–3.5% withdrawals. The extra cushion is the premium for retiring young.
Is this advice? It's a sizing rule, not a guarantee. Withdrawal safety depends on sequence-of-returns luck; flexible spending and market downturns change the picture. Use the range, not one number.
