  • Balance (at assumed rate)
  • What you put in

The gap between the two lines is compounding doing work you didn't — but only under the rate you assumed. Try 4% and 10% and see how wide that gap swings.

No Fibs — Honest Limitations

This is a deterministic calculation, not a forecast: the "annual return" is a single assumed rate, while real markets are volatile, taxed, and fee-eroded, and inflation shrinks what future money buys. No account, platform, or product here is promising that rate — change it and watch how much the answer changes, because that sensitivity is the real lesson. Nothing saves; reload and it resets.
