Portfolio Survival Calculator

How Long Will
Your Money Last?

The central question in retirement planning. Get the exact probability your portfolio survives 20, 30, 40, or 50 years — based on your withdrawal rate, investment mix, and 1,000,000 simulated market environments.

The Core Fear

Outliving Your Money — The #1 Retirement Risk

Running out of money in retirement is one of the most feared outcomes in personal finance. A 65-year-old today has a 50% chance of living past 85, and a 25% chance of reaching 92. A 45-year-old early retiree may live 50+ years in retirement.

A standard retirement calculator assuming a fixed 7% return will tell you you're fine. Monte Carlo simulation shows you the reality — the probability distribution of outcomes including the scenarios where you outlive your savings.
