Lumpsum Calculator

See how a one-time investment grows over time at a given annual return (CAGR), and how much of the final value is your principal versus compounded gains.

About the Lumpsum Calculator

A lumpsum investment puts a single amount to work for the full period, compounding annually: FV = P × (1 + r)^t. Because there are no further contributions, the entire growth comes from compounding — which is why time horizon has such a large effect on the final value.

Frequently asked questions

What is the difference between lumpsum and SIP?
A lumpsum invests one amount upfront, while a SIP spreads investments across many months. Lumpsum benefits more from a long horizon and a strong entry point; SIP averages your purchase cost over time.
What return should I assume?
Use a realistic long-term estimate for your asset class — for diversified equity funds many investors model 10–12% CAGR — and remember actual returns vary and are not guaranteed.
