Lumpsum Calculator – One-time Investment Returns

See the future value of a one-time investment with year-wise growth and inflation-adjusted value.

Money decisions are easier when you can see the numbers first. Lumpsum Calculator works with one-time investment, expected return, time period, and inflation and presents a clear estimate you can compare across scenarios.

How to Use the Lumpsum Calculator

Enter the one-time amount, the expected yearly return and the time period. Add an inflation rate to also see the value in today's money.

What is a lumpsum investment?

It is investing a whole amount at one time, instead of small monthly instalments like a SIP.

Is the return guaranteed?

No. Market-linked returns vary. The calculator assumes one fixed rate only to give an estimate.

Why show inflation-adjusted value?

Prices rise over time, so ₹1 lakh in the future buys less than today. The adjusted value shows the real purchasing power.
