Step-up SIP Calculator – Grow Investments with Rising Contributions
Use this step-up SIP calculator to see how gradually increasing your monthly investment by a fixed percentage each year can accelerate your wealth creation at a chosen annual rate of return.
Step-up SIP Calculator
Plan a step-up SIP where your monthly contribution increases by a fixed percentage each year, and estimate the future value of your investments at an assumed annual rate of return.
How the step-up SIP formula works
A step-up SIP is a variation of a regular SIP where your monthly contribution does not remain constant. Instead, it increases by a fixed percentage at regular intervals, typically once every year, while investment returns are compounded monthly.
For month m, contribution = C × (1 + s)yearIndex, where yearIndex = floor((m − 1) ÷ 12)
- C is the starting monthly contribution.
- s is the annual step-up rate expressed as a decimal (for example 0.10).
- m is the month number, starting from 1.
Each monthly contribution is then compounded at the monthly return rate until the end of the investment period. The future value is the sum of all such compounded contributions, while the total gain is the difference between this future value and the total amount you have invested over the years.
