Find out how long your portfolio will last and whether your withdrawal rate is sustainable.

Safe - historically sustainable over 30+ years

How it works

The 4% rule comes from the Trinity Study, which found that a 4% withdrawal rate survived 95%+ of 30-year retirement periods historically.

This calculator assumes the same return every single year. Markets do not work that way, and a bad run of returns in the first years of retirement can drain a portfolio that looks safe here.
