SIP Calculator with Step-up and Yearly Table

See what a monthly SIP could grow to at an assumed return, with an optional yearly step-up. An estimate for planning, not a forecast.

What this calculator does

This calculator estimates what a monthly SIP (systematic investment plan) could grow to if it earned a steady yearly return. You enter a monthly amount, an expected annual return and a number of years. You can also add an annual step-up, which raises the instalment each year. It then shows the amount invested, the estimated returns, the total value and a year-by-year table. It runs in your browser and stores nothing.

Convention and formula

The calculator follows the convention common in Indian SIP calculators: each instalment is paid at the start of the month, and the monthly rate is the annual rate divided by 12. With no step-up, the future value is:

FV = P × ((1 + i)ⁿ − 1) ÷ i × (1 + i)

Here P is the monthly amount, i is the annual return divided by 12 and 100, and n is the number of months. The final (1 + i) factor reflects payment at the start of the month. With a step-up, the calculator walks month by month and raises P at the start of each new year. At 0% return, the value is simply the total invested.

A worked example

The form is pre-filled with ₹10,000 a month at 12% a year for 10 years. That is 120 instalments, so ₹12,00,000 invested. The monthly rate is 1%, and the formula gives a total value of about ₹23,23,391. The estimated returns are about ₹11,23,391. Add a 10% annual step-up and the same plan grows to roughly ₹33,74,326 on ₹19,12,491 invested.

How to use it

Enter the amount you plan to invest each month.
Enter a return you want to test. Try a lower figure too, because actual returns vary.
Choose the number of years, and a step-up if you expect to raise the amount.
Read the totals and scroll the yearly table to see how the value builds up.

Limitations

It assumes one constant return. Real funds rise and fall, and the order of good and bad years changes the outcome.
It ignores expense ratios, exit loads, taxes and inflation. A real, after-tax result will be lower than the projection.
Monthly compounding at annual divided by 12 is a convention. It is not the same as an effective annual rate of 12%, which is higher.
To measure the return of a SIP you have already run, use XIRR on the real dates and amounts.

Frequently asked questions

Is the SIP calculator result guaranteed?

No. Market-linked investments do not earn a fixed return. The calculator assumes one steady yearly rate, which real markets never deliver, so treat the output as an illustration.

Why does this use payment at the start of each month?

Many Indian SIP calculators assume the instalment goes in at the start of the month, which adds one extra month of growth to every instalment. It is a convention. A calculator that assumes month-end payments will show a slightly lower value.

What does the annual step-up do?

It raises your monthly amount by the chosen percentage at the start of each year after the first. A 10% step-up turns ₹10,000 a month into ₹11,000 in year two.

How is this different from XIRR?

This calculator projects a future value from an assumed return. XIRR measures the return you actually earned from real dated cash flows. Use the XIRR calculator on past investments.
