About this calculator

The reverse of the Compounder calculation: instead of asking "what will this grow to," it asks "how much do I need to add each year to hit a target?"

Solves algebraically for the exact yearly contribution, then simulates year by year for the breakdown table
The precise (unrounded) contribution is used internally for all totals — only the number shown on screen is rounded
Because of that, manually multiplying the displayed contribution by the number of years won't always exactly match the displayed Total Invested — a small, expected rounding gap common to all such calculators

Not investment advice — for planning and comparison only.
