How this calculator works

Most retirement calculators compress your life into one average-return number. This one is a sandbox: it projects your balances year by year under bear, base and bull market scenarios side by side, because the order and spread of returns — not the average — is what actually decides whether a plan survives.

Common questions

Is it really free?

Yes. The full calculator runs anonymously — no account, no email. Signing in (free) saves your scenarios across devices. Pro auto-fills your live account balances.

Where do my starting balances come from?

Type them in, or — if you track your money in the same app's net worth dashboard — Pro users have their real per-account balances filled in automatically, keeping the projection honest.

Does it give financial advice?

No. It's a projection sandbox for your own assumptions — a way to see the consequences of choices, not a recommendation engine. Not financial advice.
