How It Works

How SIP maturity value is calculated

A SIP invests a fixed amount every month, and each installment compounds for a different length of time depending on when it was invested. The maturity value is calculated using the future value of a growing annuity formula: M = P × [((1 + i)^n − 1) / i] × (1 + i), where P is the monthly investment, i is the monthly rate of return, and n is the total number of monthly installments.

For example, investing 5,000 per month for 15 years (n = 180) at an expected annual return of 12% (i = 1% monthly) grows to roughly 25.2 lakh, compared to a total invested amount of 9 lakh, meaning about 16.2 lakh comes purely from investment growth.

Why starting a SIP early matters

Because SIP returns compound monthly, earlier installments have far longer to grow than later ones. This is why extending the investment period, even by a few years, tends to have a much larger impact on the final maturity amount than increasing the monthly contribution by a similar percentage.

Frequently Asked Questions

What return rate should I use for my SIP?

This depends on where you're investing. Equity mutual funds have historically returned around 10-15% annually over the long term, but returns aren't guaranteed and vary by fund and market conditions. Use a conservative estimate for planning purposes.

Does this account for expense ratios or exit loads?

No, this calculator estimates gross returns based on your expected annual rate. Actual returns from a mutual fund SIP will be reduced by fund expense ratios and any applicable exit loads.

Can I use this for a lump sum investment instead?

This calculator is designed for recurring monthly investments. For a one-time lump sum, use our Compound Interest Calculator instead.
