Calculates how much you can safely withdraw each year from your retirement portfolio — in both annual and monthly amounts — based on your withdrawal rate, expected return, inflation, and retirement duration.
Annual Withdrawal = Portfolio × Withdrawal Rate
At a 4% withdrawal rate, a $1M portfolio yields $40,000/year ($3,333/month) in Year 1. With 7% nominal return and 3% inflation, real return is 4% — the portfolio historically survives 30+ years.

The safe withdrawal rate (SWR) is the percentage of your retirement portfolio you can withdraw each year without running out of money over a defined period. The most widely cited figure is 4%, based on the 1994 Trinity Study which analysed US historical stock and bond returns over 30-year retirements.
The 4% rule has held up historically, but some researchers now suggest 3.3–3.5% given lower expected bond returns, higher valuations, and early retirees needing 40+ year horizons. For a 30-year retirement with a diversified portfolio, 4% remains a widely used starting point.
Sequence-of-returns risk is the danger of experiencing poor market returns early in retirement while withdrawing from the portfolio. Even if average long-run returns are fine, bad early years can permanently deplete the portfolio before markets recover. This is why early retirement requires a more conservative withdrawal rate.
Traditional implementations of the 4% rule adjust the withdrawal amount each year for inflation (so purchasing power stays constant). This calculator shows your Year 1 withdrawal; in practice, increase it by your inflation rate each year to maintain the same real spending.
