How do I project my retirement savings?
Use the 401k or Retirement Calculator to project your balance from contributions, employer match, and expected return. The FIRE and Coast FIRE calculators show the number you need to retire early.
What return rate should I assume?
A common long-run assumption for a diversified stock portfolio is 6–7% after inflation, but returns vary year to year. Try a range of rates to see best- and worst-case outcomes.
