How it works

How the Lumpsum Calculator works

A lumpsum means investing the whole amount in one go. Your entire capital starts compounding from day one — which is why, over a long period, even a small difference in rate becomes a large difference in value.

Formula

FV = P × (1 + r)^n

P = invested amount, r = annual return (as a decimal), n = years.

FAQ

Lumpsum Calculator — common questions

Is a lumpsum better than a SIP?

Both have a role. A lumpsum suits you when you have a large amount at once and can stomach the volatility; a SIP suits regular investing out of your salary. Many people do both.

How often is compounding applied?

This calculator assumes annual compounding, which is the standard way mutual fund returns are presented.

How do I account for inflation?

Subtract inflation from the expected return. For example, with a 12% return and 6% inflation, enter 6% — that gives you the result in today's money.
