Spending down on purpose
The 4% rule aims to make money last 30 years in almost any historical market, which means in most cases it leaves a large balance behind. If you would rather spend your savings over a fixed period, this calculator finds the level, inflation-adjusted withdrawal that runs the balance down to your chosen ending amount exactly when the period ends.
With $800,000, 30 years and a 3% real return, that is about $39,600 a year, close to the 4% rule. Over 40 years it drops to about $33,600 a year, and over 20 years it rises to about $52,200.
Use it with care
A fixed real return hides the risk of bad years early in retirement. Treat the result as a ceiling for a smooth world and plan a little below it, or adopt a flexible rule such as cutting withdrawals by 10% after a year when the portfolio falls.

2% to 4% after inflation is a common conservative range for a balanced portfolio.
