How Long Will My Money Last Calculator

A free, no-sign-up retirement drawdown calculator that turns a starting balance and monthly spending gap into a transparent money-runway scenario. It models one level monthly withdrawal, a constant nominal annual return, a target duration, and beginning- or end-of-month withdrawal timing. Results include the estimated runway, target gap, target-fit monthly amount, and a projected balance chart and annual table. Inflation, taxes, fees, deposits, and market swings are not modeled, so the result is an educational scenario rather than a forecast or guarantee.
What problem it solves
It turns a savings balance and monthly withdrawal need into an auditable runway estimate, while showing how the same assumptions compare with a chosen target duration.
