Retirement calculators
Simple calculators for the questions most retirement plans start with, plus a way to compare withdrawal strategies. Each one works in any currency, shows its formula and assumptions, and runs entirely in your browser: nothing you type is sent or stored.
The first three calculators build on each other: how much you need, how long that money could last, and at what age you could get there. The fourth shows how the order of good and bad years affects different withdrawal approaches. They need no app or account. The results are educational estimates based on the numbers you enter, not forecasts and not personal advice.
How much do I need?
Your savings target from yearly spending, other yearly income and a withdrawal rate, in today's money. Any currency.
Open LiveHow long will my money last?
How many years your savings could pay your yearly spending as it rises with inflation, with a year-by-year table.
Open LiveCan I retire at X?
Compare your projected savings at the age you choose with the nest egg you would need, and see the earliest age it could work.
Open LiveWithdrawal scenarios
Compare fixed, lower-rate, dynamic and guardrail withdrawals under the same steady, bad-first and good-first return paths.
