Enter the goal, the time, and a rate, then press Calculate.
From the book — Chapter 5. Work backwards from the goal. What you already have keeps growing; the rest has to come from regular saving plus the interest those deposits earn. This solves for the monthly amount — and shows how much of the target your own deposits cover versus how much interest adds.
Compounded monthly; the rate is illustrative, not a quoted or guaranteed return. Educational only, not investment advice. Everything stays in your browser.
