How Long Will My Savings Last?

See how long your nest egg lasts while you make monthly withdrawals.

Your savings last
In months

Estimate based on a constant return. Real returns vary year to year; a down market early in retirement can shorten this significantly.

This models a nest egg that earns a steady return while you draw from it each month, and solves for when the balance hits zero. If your withdrawal is small enough, the earnings cover it and the money never runs out.
