Formula
FV = P × [((1+r)^n - 1) / r] × (1+r)
Example
₹5,000 monthly SIP at 12% for 10 years can grow to around ₹11.6L.
How does the SIP future-value formula work?
Each monthly instalment is assumed to earn the same monthly rate, and the next instalment is added after that growth. The closed form is FV = P × (((1 + r)^n − 1) ÷ r) × (1 + r). A ₹5,000 monthly SIP at 12% a year for 10 years grows to ₹11,61,695.38 on this formula, which is the example quoted on the page as about ₹11.6 lakh.
The invested amount is simply monthly SIP times the number of months. The gap between future value and invested amount is growth, not a guaranteed profit.
Real SIPs have entry days, exit loads, expense ratios, and returns that move. This page holds the rate still so you can see the arithmetic.
How is a SIP different from compound interest on a lump sum?
A SIP adds new money every month. Compound interest on this site grows one starting principal. The same annual rate will not produce the same result, because the cash flows are different.
Use the compound-interest calculator when you already have a lump sum. Use this page when you plan to invest a fixed amount every month.
How to use this calculator
- Enter the monthly SIP. This is the amount invested at the end of each month, in rupees.
- Enter the expected annual return. This is a guess you choose, not a promised fund return. The page divides it by 12 and by 100.
- Enter the number of years. The page turns years into months. The result is a future value, not the amount you paid in.
Questions about SIP Calculator
Is the SIP return guaranteed?
No. The rate is an assumption you type. A fund, a deposit, or a market can return more or less, and can lose value.
Does the formula invest at the start or the end of the month?
The factor (1 + r) outside the brackets treats each instalment as earning one month of return, which is the usual future-value form for a payment at the beginning of the compounding step. Your SIP date can differ.
What does ₹11.6 lakh mean in the example?
It is a rounded future value for ₹5,000 a month at 12% a year for 10 years, not a promise and not your personal result.
Can I enter a zero return?
No. The formula divides by the monthly rate, so the rate has to be greater than zero. With no growth, the future value would simply be the sum of the instalments.
Read the guide
A SIP adds money every month. Compound interest grows one lump sum. Simple interest pays P × R × T ÷ 100 and does not add interest back onto the principal. A ₹5,000 monthly SIP at 12% for 10 years becomes ₹11,61,695.38 on the SIP page. ₹10,000 at 7% compounded yearly for 5 years becomes ₹14,025.52. ₹50,000 at 8% simple interest for 3 years earns ₹12,000.
