A lumpsum investment is money you invest once, such as a bonus, an inheritance or the proceeds of a sale, and then leave to grow. This calculator shows its estimated value after a chosen number of years, assuming returns compound once a year.

Example

  • ₹1 lakh invested at an assumed 12% a year grows to about ₹3.11 lakh in 10 years.
  • ₹5 lakh at 10% a year for 15 years grows to about ₹20.89 lakh, more than four times the original amount.

Things to keep in mind

  • The expected return is an assumption. Equity markets do not rise in a straight line, and the value can be lower than the amount invested in some years.
  • If you are worried about investing everything at a market high, you can spread the money over a few months using a systematic transfer plan (STP).
  • Inflation reduces what the final amount can buy. At 5% inflation, prices roughly double in about 14 years.

How this is calculated

FV = P × (1 + r)t

P is the amount invested, r is the expected annual return (as a decimal) and t is the number of years.

Assumptions

  • Returns compound once a year at a constant rate. Real market returns vary from year to year.

Frequently asked questions

What return should I assume?

Use a conservative figure and test a range. For long-term equity investments many planners use 10% to 12%; for debt investments, lower. Past returns do not guarantee future returns.

How is this different from a SIP?

A lumpsum is invested once; a SIP invests a fixed amount every month. Use the SIP calculator for monthly investments.
