What it does
The SIP calculator works out the arithmetic of a monthly SIP at a steady yearly return:
- Estimated value: what the payments may grow to by the end of the period, for example 1,161,695.38 for 5,000 a month at 12% a year over 10 years.
- Amount invested: the total of your payments, 600,000.00 in that example.
- Estimated returns: the estimated value minus the amount invested, 561,695.38 in that example.
The result updates as you type. It calculates; it doesn’t tell you what to invest in.
How to use it

How it’s calculated
The calculator follows the usual Indian SIP convention: the monthly rate i is the yearly rate divided by 12, and each payment is made at the start of a month. With the monthly investment P and the number of monthly payments n:
FV = P × ((1 + i)^n − 1) ÷ i × (1 + i)
For 5,000 a month at 12% a year over 10 years, i = 0.01 and n = 120, so FV is 1,161,695.38. At 0%, FV = P × n.
Each payment grows for the months it’s invested: the first for all n months, the last for one month. The calculator adds these exactly and rounds the total half up to whole cents once, so no rounding builds up along the way.
The return is assumed to be the same every month. Fees, exit loads and tax aren’t included.
Good to know
- The monthly investment can be from 1 to 1,000,000,000, and is rounded to whole cents.
- The expected return can be from 0% to 50% a year, in steps of 0.01.
- The period is a whole number of years from 1 to 50, so at most 600 payments.
- No currency is assumed: the amounts are in whatever currency you type.
