SIP Corpus Calculator
A Systematic Investment Plan invests a fixed amount in mutual funds every month. Each instalment compounds for the months remaining, so the corpus at the end is larger than the sum of your contributions by the gains.
Expected corpus
$2,300,386.89
- Total invested
- $1,200,000.00
- Estimated gains
- $1,100,386.89
- Gains as share
- 47.83%

The formula this calculator uses
Corpus = P x ((1 + i)^n - 1) / i
- P
- Monthly instalment
- i
- Monthly rate of return
- n
- Number of monthly instalments
How to check the result by hand
- 1
Convert the return to a monthly rate
Divide the expected annual return by twelve to get the monthly rate used in the annuity factor.
- 2
Count the instalments
Multiply the tenure in years by twelve to get the number of monthly instalments.
- 3
Apply the annuity factor
Raise one plus the monthly rate to the number of months, subtract one and divide by the monthly rate.
- 4
Multiply by the instalment
Multiplying the annuity factor by the monthly instalment gives the projected corpus.
- 5
Split contributions from gains
Multiply the instalment by the number of months to get the amount invested, then subtract it from the corpus to see the gains.
