How to use the retirement calculators
The savings and 401(k) calculators handle accumulation: what your balance looks like at retirement given contributions, employer match, and expected returns — including how much free match money you are leaving behind each year.
Roth vs traditional compares after-tax value under your current and expected future tax rates, and the withdrawal calculator runs the drawdown year by year against inflation to show the year the balance runs out at a given spend rate.
Every calculator on this page keeps your inputs in the URL, so you can bookmark a scenario or send it to someone else and they will see the exact same result.
