SIP Calculator
Free SIP calculator for India. Estimate the future value of your monthly mutual fund SIP, with an optional yearly step-up.
How this SIP calculator works
A Systematic Investment Plan (SIP) invests a fixed amount in a mutual fund every month. Each instalment buys units at that day's NAV, so you buy more units when prices are low and fewer when they are high. This calculator assumes a constant annual return, converts it to a monthly rate, and compounds each instalment from the month it is invested.
The formula for a regular SIP, with instalments at the start of each month, is:
FV = P × [((1 + i)n − 1) / i] × (1 + i)
where P is the monthly amount, i is the monthly rate (annual rate ÷ 12) and n is the number of months. With a step-up, the instalment rises by your chosen percentage at the start of every year, which is how most people's incomes actually grow.
Worked example
Investing ₹10,000 a month for 15 years at 12% a year gives a corpus of about ₹50.5 lakh on a total investment of ₹18 lakh, so the estimated gain is roughly ₹32.5 lakh. Raise the monthly amount by 10% each year and the same 15 years ends near ₹87 lakh.
What return should you assume?
Equity mutual fund returns are not guaranteed and vary widely by year. Long-run equity assumptions are often between 10% and 12%, but a cautious plan uses 8–10%. Debt funds historically return less. Try several rates; the spread between them shows you the real uncertainty.
Things this calculator does not include
- Expense ratio is already reflected in a fund's reported returns, but exit loads are not modelled.
- Long-term capital gains tax on equity funds is not deducted. Check current rules before planning withdrawals.
- Inflation: ₹50 lakh in 15 years buys less than ₹50 lakh today. Use a lower rate to approximate real returns.
Frequently asked questions
Is SIP return guaranteed?
No. SIPs in market-linked funds carry risk and the result shown is only an estimate based on the rate you enter.
What is a step-up SIP?
A step-up SIP raises your monthly instalment by a fixed percentage every year, so your investing keeps pace with salary growth.
Can I stop a SIP anytime?
Most open-ended mutual fund SIPs can be paused or stopped without a penalty, though some schemes have an exit load on units redeemed early.
