How it works
A systematic investment plan puts a fixed amount into a fund every month. Each instalment compounds for a different length of time, so the maturity value is the sum of every instalment's growth: FV = P × [((1 + i)n − 1) ÷ i] × (1 + i), where i is the monthly return and n the number of instalments.
- Enter the monthly amount, the return you expect each year and how long you will invest.
- The annual return is divided by 12 to get the monthly rate.
- The calculator adds up what each instalment grows into by the end.
The return you type is an assumption, not a promise — Indian equity funds have historically returned somewhere near 12% a year over long periods, with years well above and well below that. Run the numbers at 10% and 14% too and plan with the lower one.
Examples
What regular investing adds up to:
- ₹5,000 a month for 10 years at 12%: you invest ₹6,00,000 and it grows to about ₹11,61,695.
- ₹10,000 a month for 20 years at 12%: you invest ₹24,00,000 and it grows to about ₹99,91,479 — most of it is growth, not your money.
- The same ₹10,000 for 10 years instead of 20 reaches only ₹23,23,391. Time matters more than the amount.

SIP Calculator: frequently asked questions
- How is SIP return calculated?
- Each monthly instalment compounds for the remaining months. The formula FV = P × [((1+i)^n − 1)/i] × (1+i) adds them up, with i = annual return ÷ 12.
- Are SIP returns guaranteed?
- No. Mutual fund SIP returns depend on market performance; the calculator uses a constant assumed rate for illustration.
- What is a step-up SIP?
- A SIP where you increase the monthly amount each year (for example by 10%), which can grow the final corpus significantly.
