Lumpsum Calculator

A lumpsum is a one-time investment, unlike a SIP where you invest every month. This calculator shows what a single amount could grow to over the years at a return you expect, using annual compounding.

Compare it with the SIP calculator to see how investing at once differs from investing gradually.

How to use this calculator

  1. Enter the amount you plan to invest.
  2. Enter the return you expect per year.
  3. Enter the number of years.
  4. Read the future value, the returns and the year-wise table.

Formula and variables

Future value = P × (1 + r)^t

  • P - the amount invested.
  • r - expected annual return as a decimal (12% = 0.12).
  • t - number of years.

Worked example

₹1,00,000 invested once at an expected 12% a year for 10 years.

Inputs and results for the worked example
Amount₹1,00,000
Return and period12% for 10 years
Future value₹3,10,585
Returns₹2,10,585
  1. Growth factor = 1.12¹⁰ = 3.1058.
  2. Future value = 1,00,000 × 3.1058 = ₹3,10,585.
  3. Returns = 3,10,585 − 1,00,000 = ₹2,10,585.

What changes the result

  • Return rate. Even small differences in the rate make a large difference over long periods.
  • Time. Compounding works best over long periods, as returns earn returns.
  • Taxes. Capital gains tax reduces what you finally keep. Use the capital gains calculator.
  • Costs. Expense ratios and fees lower the net return.

Benefits and practical uses

  • See the long-term effect of a one-time investment.
  • Compare lumpsum with SIP.
  • Set realistic goals with a year-wise view.

Assumptions and limitations

  • Returns are assumed to be constant and compounded annually.
  • No taxes, exit loads or expense ratios are deducted.
  • Market-linked returns are not guaranteed.

Frequently asked questions

What is a lumpsum investment?

Investing a single amount at one time, instead of in instalments.

How is lumpsum return calculated?

Future value = amount × (1 + annual return)^years.

Is lumpsum better than SIP?

It depends. A lumpsum is exposed to market levels on one day, while a SIP spreads the entry over time. Compare both for your situation.

What return should I assume?

Use a cautious figure. Past returns do not guarantee future returns, and equity returns vary a lot year to year.

Are returns taxed?

Yes, as capital gains or interest depending on the product. Taxes are not deducted here.
