Lumpsum Calculator

Calculate how a one-time investment could grow over time.

ⓘ How this works

A "lumpsum" investment means putting in a single, one-time amount all at once (as opposed to a SIP, where you invest smaller amounts regularly). This calculator shows how that one-time investment could grow over the years thanks to compounding — earning returns not just on your original amount but on the returns it has already generated.

Roughly 68% of your final corpus comes from growth, not contributions.
A lump sum invested just before a market fall can take years to recover. Consider staggering large amounts (STP) if the timing matters.

Risk note · Market-linked investments (mutual funds, stocks, SIPs) carry risk. The return you enter is an assumption — actual returns vary year to year, can be negative, and past performance does not predict future results. A smooth projected curve never happens in real markets; the final figure can land well above or below it.

Disclaimer · finkit is an educational tool, not financial, tax or legal advice. Every result is a projection from the numbers you entered and the assumptions stated on the page — it is not a forecast, a quote, or an offer. Check decisions with a SEBI-registered adviser, your lender, or a tax professional.
