What is the Lumpsum Calculator?
A lumpsum calculator shows what a one-time investment could be worth after a number of years. Enter the amount — a bonus, a maturity payout, an inheritance — the annual return you expect and how long you will leave it invested, and it shows the projected value and how much of it is growth.
The money compounds once a year, so each year’s return is earned on the previous years’ returns as well as on what you put in. The year-by-year table makes that snowball visible, and comparing a few return rates shows how much the choice between equity, hybrid and debt funds matters over a long horizon. Everything is calculated in your browser.
