Estimates what a one-time investment grows to at an assumed yearly return — for a mutual fund lump sum, a bonus you invest, or any sum left to compound.

Understanding the result

Maturity value is the estimated amount at the end; estimated gain is what the growth added to your investment. The return is an assumption: market-linked investments do not grow at a steady rate.

For a tenure past a year, the year-by-year breakdown shows the balance each year opens with, its gain and the closing balance. Export CSV downloads it.

How to use it

  • Investment amount — the sum you invest once.
  • Expected annual return — from 0.1% to 100%.
  • Investment duration — in years (1 to 100) or months (1 to 1,200).

How it works

Growth compounds once a year. A duration in months is converted to years, so 18 months compounds for 1.5 years. The result is rounded to the nearest rupee.

Maturity value = P × (1 + R ÷ 100)ᵗ
P = amount, R = annual return %, t = years

Examples

₹1 lakh for 10 years at 12%

It grows to about ₹ 3,10,585, a gain of ₹ 2,10,585: the original sum multiplied 3.1 times.
