Lumpsum Calculator
Grow a one-time investment. Project the future value of a single one-time mutual fund investment over any holding period.
About the Lumpsum Calculator
A lumpsum investment puts the entire amount to work on day one, so every rupee compounds for the full tenure. That makes lumpsum returns more sensitive to entry timing than a SIP, but it also means a longer holding period does more work. Enter the amount, the return you expect and the years you will hold to see the projected maturity value.
Lumpsum maturity formula
FV = PV x (1 + r)^n
- FV
- Future value at maturity
- PV
- Amount invested today
- r
- Annual rate of return (as a decimal)
- n
- Number of years held
This is standard annual compounding. Because the exponent sits on the tenure, each additional year adds more than the one before it.
Using this calculator
- Enter the one-time amount you plan to invest.
- Set the annual return you expect.
- Choose your holding period in years.
- Compare the total value against the invested amount to see the compounding share.
Lumpsum Calculator FAQs
Is a lumpsum better than a SIP?
Neither wins universally. A lumpsum outperforms when markets rise steadily after you invest, because all your money compounds from day one. A SIP performs better through volatile or falling markets, because later instalments buy at lower prices.
When does a lumpsum make most sense?
Usually when you receive a genuinely one-off sum - a bonus, maturity proceeds, or a property sale - and your holding period is long enough to absorb a bad entry point. Short horizons magnify timing risk considerably.
Can I reduce the risk of investing at a market peak?
A systematic transfer plan is the common approach: park the lumpsum in a liquid fund and move a fixed amount into equity each month. You keep the money invested while spreading the entry price across several months.
What return rate should I use?
Use a category average rather than a recent headline number. Equity funds have historically returned roughly 10-12% a year over long periods and debt funds 6-8%. Testing a lower rate shows how much of your plan depends on optimism.
Does this calculator deduct tax or exit load?
No, it projects gross maturity value. Capital gains tax applies on redemption and depends on fund type and holding period, and exit load may apply if you redeem early. Treat the result as pre-tax.
