SIP Calculator
See what a monthly SIP could grow into. Estimate the maturity value of a monthly mutual fund SIP, and see how much of it is your money versus compounding.
About the SIP Calculator
A Systematic Investment Plan (SIP) invests a fixed amount in a mutual fund at a fixed interval, usually monthly. Because every instalment buys units at a different price and then compounds for a different length of time, the maturity value is not simply your contribution times a return rate. This calculator does the compounding for you and separates what you put in from what the market added.
SIP maturity formula
M = P x ({[1 + i]^n - 1} / i) x (1 + i)
- M
- Maturity value
- P
- Monthly SIP amount
- i
- Monthly return rate (annual rate / 12 / 100)
- n
- Total number of instalments
The trailing (1 + i) assumes each instalment is invested at the start of the month. Investing at the end of the month drops that term.
Using this calculator
- Enter the amount you can invest every month.
- Set the annual return you expect from the fund category.
- Choose how many years you will stay invested.
- Read the maturity value, and compare it against the invested amount to see the compounding share.
SIP Calculator FAQs
How does a SIP calculator work?
It compounds each instalment separately for the time it stays invested, then adds them up. An instalment paid in year one compounds for the full tenure, while the final instalment compounds for a month. That is why maturity value grows far faster than total contributions.
What is a realistic return rate to enter?
Match the rate to the fund category, not to one fund's best run. Equity funds have historically delivered roughly 10-12% a year over long periods, hybrid funds 8-10% and debt funds 6-8%. Lower assumptions produce plans that survive bad years.
Are SIP returns guaranteed?
No. SIPs invest in market-linked mutual funds, so returns vary and capital can fall in value. The calculator projects one constant rate for clarity, but real returns arrive unevenly - some years strongly positive, some negative.
Does a longer SIP really matter that much?
Substantially. Compounding is exponential, so the last few years contribute the largest absolute gains. Extending a 10-year SIP to 15 years typically more than doubles the maturity value, even though contributions rise by only half.
How are SIP returns taxed in India?
Each instalment is treated as a separate purchase for holding-period purposes. For equity funds, units held over 12 months qualify as long-term capital gains; shorter holdings are short-term. Debt fund taxation differs. Confirm current rates with a qualified tax adviser.
Should I stop my SIP when markets fall?
Falling markets are when a SIP buys the most units for the same amount, which is the mechanism that drives rupee-cost averaging. Stopping during a decline locks in the downside and removes the recovery. This is general information, not personal advice.
