About Lumpsum Calculator

What it calculates

For a single one-time investment, the tool computes value = amount × (1 + expected return)^years and reports the invested amount, the expected value and the gain. It is the same compound-growth idea as the compound-interest tool, with annual compounding fixed.

Worked example

Rs. 5,00,000 invested for 10 years at an assumed 12% a year becomes about Rs. 15,52,924, a gain of about Rs. 10,52,924.

How to use it sensibly

  • The return you enter is an assumption, not a forecast. Equity fund returns vary widely year to year, so try a low, middle and high case such as 8%, 10% and 12%.
  • Results are before tax, exit loads and expense ratios. Use a rate that is already net of fund costs if you want a realistic picture.
  • For the actual performance of something you already hold, the mutual fund returns calculator works from buy and current NAV instead.

Lumpsum or SIP?

A lumpsum is exposed to the market from day one, so timing matters more. A SIP spreads purchases over time. Compare both with the same assumed rate to see how much each approach needs to reach a target.

Frequently Asked Questions

This assumes a single upfront investment that then compounds untouched for the full tenure. A SIP instead spreads the investment across regular monthly contributions — use the SIP Calculator for that scenario.

Standard annual compound growth: the invested amount grows by the entered rate of return each year, compounding on the previous year's value.

Lump-sum investing can suit a large one-time inflow (like a bonus or maturity payout) when markets are reasonably valued, while SIP is often preferred for spreading market-timing risk across regular income.

The amount invested, the projected value at the end of the tenure, and the estimated returns (the difference between projected value and invested amount).

No — the rate of return you enter is an assumption. Actual investment performance depends on market conditions and is never guaranteed.
