FV = P × [((1 + i)ⁿ − 1) ÷ i] × (1 + i), with i = annual return ÷ 12 and each instalment invested at the start of the month. The green line is the SIP value, the dashed line is the money you put in. Returns are an estimate at a steady rate — real mutual fund returns vary, and fees and tax are not included.

Frequently Asked Questions

What is a SIP?

A SIP, or Systematic Investment Plan, is a way of investing a fixed amount into a mutual fund at a regular interval, usually every month, instead of putting in one lump sum. Each instalment buys units at that day's price, so you buy more units when prices are low and fewer when they are high. Over long periods the regular investing plus compounding is what makes a SIP grow.

How is SIP return calculated?

This calculator uses the standard SIP formula FV = P × [((1 + i)ⁿ − 1) / i] × (1 + i), where P is the monthly instalment, i is the expected annual return divided by 12 and n is the number of months. It assumes each instalment is invested at the start of the month. For example, ₹10,000 a month for 10 years at 12% a year grows to about ₹23.23 lakh, of which ₹12 lakh is the money you put in and about ₹11.23 lakh is estimated returns.

What is a step-up SIP?

A step-up (or top-up) SIP raises the monthly instalment by a fixed percentage once a year, usually in line with salary increases. Enter the yearly increase in the Annual step-up box: at 10%, a ₹10,000 SIP becomes ₹11,000 a month in year two and ₹12,100 in year three. Because the extra money has many years to compound, even a small step-up makes a large difference to the final value.

How does inflation affect my SIP returns?

Inflation reduces what your future money can buy. Enter an inflation rate and the calculator shows the final value in today's money by dividing it by (1 + inflation)^years. At 6% inflation, ₹1 crore in 20 years buys roughly what ₹31 lakh buys today, so the inflation-adjusted figure is the better guide to whether a goal is really on track.

Are SIP returns guaranteed?

No — mutual fund SIPs are market-linked, so the real return changes every year and can be negative over short periods. The expected return you enter is an assumption, and the result is an estimate at a steady rate, not a promise. This calculator also ignores fund expense ratios, exit loads and tax on gains. Use it to compare scenarios and set goals, and read the scheme documents or speak to a SEBI-registered adviser before investing.
