How SIP value is calculated
Each monthly instalment grows for the months that remain. Adding them all up gives the standard future-value formula for regular payments made at the start of each month:
FV = P × [((1 + r)n − 1) ÷ r] × (1 + r)
P is the monthly instalment, r is the monthly return (yearly return ÷ 12 ÷ 100) and n is the number of instalments.
Example: ₹10,000 a month at 12% a year for 10 years is 120instalments, ₹12,00,000 in total. The estimated value is₹23,23,391, so ₹11,23,391 of it is returns.
Frequently asked questions
What is a SIP?
A Systematic Investment Plan (SIP) is a way to invest a fixed amount in a mutual fund at regular intervals, usually every month. Each instalment buys units at that day's NAV (price per unit), so you buy more units when prices are low and fewer when they are high.
Are the returns shown here guaranteed?
No. Mutual fund returns depend on the markets and change from year to year. The calculator assumes the same return every year, so treat the result as an estimate. It helps to check a cautious case too: at 8% instead of 12%, the same SIP would grow to about ₹18.42 lakh instead of ₹23.23 lakh.
How much difference does time make?
A lot, because returns start earning returns of their own. ₹10,000 a month at 12% for 10 years grows to about ₹23.23 lakh. Keep going for 20 years and you invest twice as much (₹24 lakh), but the value grows to about ₹99.91 lakh — around 4 times as much.
Why is my fund statement different from this calculator?
Your statement uses the real NAV on each instalment date, so it reflects how the market actually moved. This calculator uses one steady return. Exit loads and taxes on redemption are also not included here.
Is the money from a SIP taxed?
Gains are taxed as capital gains when you sell (redeem) your units. The rate depends on the type of fund and how long you held each instalment's units. This calculator shows the value before tax.
