How it works

How the SIP Calculator works

With a SIP you invest a fixed amount every month. Two things work in your favour — compounding (returns on your returns) and rupee cost averaging (you buy more units when the market falls). That is why time matters more than the amount in a SIP.

Formula

M = A × [(1+i)^n − 1] ÷ i × (1+i)

Here A = monthly amount, i = monthly return (annual ÷ 12 ÷ 100), n = total number of months.

FAQ

SIP Calculator — common questions

Are SIP returns guaranteed?

Not at all. Mutual fund returns depend on the market. This calculator gives an estimate at one assumed constant rate — actual returns will move up and down every year.

What expected return should I assume?

No number is guaranteed. People commonly assume 10-12% for equity funds and less for debt funds, but that is only a planning assumption, not a promise.

Can I increase my SIP amount later?

Yes — that is called a step-up or top-up SIP. Increasing it a little each year raises the maturity value substantially, because the extra amount also gets compounded.

Is a SIP taxed?

Yes, capital gains tax applies on redemption, and the rules depend on the fund type and holding period. Confirm your own situation with a qualified tax advisor.
