How the Lumpsum Calculator works

FV = P × (1 + r)t

  • P — amount invested today
  • r — assumed annual return ÷ 100
  • t — years

This is plain annual compounding: every year's growth is added to the amount and itself earns returns the following year.

Worked example

500,000 invested once, for 10 years, at an assumed 12% a year:

Growth factor (1.12)103.1058
Future value1,552,924
Estimated gain1,052,924

The 500,000 would grow to about 1,552,924 at that assumed rate.

The arithmetic is the same in any currency; the calculator shows results in the currency you pick.

Frequently asked questions

Lumpsum or SIP — which gives more?

For the same total amount and the same return, money invested earlier has longer to compound. Real outcomes depend on market timing and are not predictable; the calculators only compare the arithmetic.
