A step-up SIP raises the monthly instalment by a fixed percentage every year, typically in line with salary increments. The effect on the final value is large because the higher instalments compound for years. Enter the starting amount, expected return, period and the yearly step-up; the calculator shows the maturity value, the total you actually invested and the year-by-year build-up.
Set the step-up to 0 for a plain SIP. Returns are assumptions, not guarantees; run the calculation at 8%, 12% and 15% to see the range.
SIP Calculator
A systematic investment plan puts a fixed amount into a mutual fund every month, and the SIP calculator shows what that discipline adds up to. The maths is compound interest applied to a stream of payments: ₹10,000 a month for ten years is ₹12 lakh invested, and at a 12% expected annual return it grows to roughly ₹23.2 lakh, so almost half of the final value is gains rather than contributions. The year-by-year table shows how slowly it starts and how fast it finishes.
Add a step-up percentage to model raising the instalment every year as your income grows; a 10% annual step-up on the same plan raises the amount invested to about ₹19 lakh and the final value to roughly ₹33.7 lakh. The expected return is an assumption, not a promise: equity funds have averaged around 12% over long periods but have had many losing years along the way, so run the calculation at 8% and 15% as well to see the range. For a one-time investment use the compound interest calculator.

Frequently Asked Questions
How much difference does a 10% step-up make?
On ₹10,000 a month for ten years at 12%, a plain SIP invests ₹12 lakh and grows to about ₹23 lakh; a 10% annual step-up invests about ₹19 lakh and grows to roughly ₹34 lakh.
When does the step-up apply?
Once a year, at the start of each new year of the plan, matching how most fund houses implement top-up SIPs.
Are step-up SIP returns guaranteed?
No. Mutual fund values fluctuate; the calculator projects a constant assumed return.
