How this calculator works

Compound Investment

Compounding means estimated returns are earned on both the money contributed and previous growth. The result is an illustration, not a guaranteed return.

01

Formula

Future value combines monthly compounding of the initial amount with contributions made at the end of each month.

02

Simple example

Try Rs. 500,000 initially, Rs. 25,000 monthly, 8% annually, and 10 years to see contributions compared with estimated growth.
