A step up SIP calculator estimates what your mutual fund SIP could be worth if you raise the monthly amount by a fixed percentage every year. Type your starting SIP, the expected return, the number of years and the yearly step up. You see the estimated value, how much you would invest in total and how it compares with a flat SIP.
Most people's income rises over time, so a SIP that rises with it is more realistic than one that stays the same for 20 years. Even a 5% or 10% yearly raise changes the end result a lot.

How the step up SIP calculator works
The calculator runs the SIP month by month. For the first 12 months it invests your starting amount. At the start of year 2 it raises the amount by your step up percentage, and so on each year. Every instalment grows at the monthly rate from your expected return until the end of the period.
Example: ₹5,000 a month, step up 10%, so the SIP is ₹5,000 in year 1, ₹5,500 in year 2, ₹6,050 in year 3 and ₹30,580 in year 20. If the fund grows 12% a year, the total invested is about ₹34.4 lakh and the estimated value is ₹99,44,358. A flat ₹5,000 SIP at the same return reaches ₹49,95,740.
Flat SIP vs step up SIP
| ₹10,000 a month at 12% for 15 years | Total invested | Estimated value |
|---|---|---|
| Flat SIP | ₹18,00,000 | ₹50,45,760 |
| 5% yearly step up | about ₹25,90,000 | about ₹65,00,000 |
| 10% yearly step up | ₹38,12,698 | ₹86,83,849 |
A step up SIP grows more mainly because you invest more. The gain per rupee invested is actually lower than a flat SIP, since the larger later instalments have less time to grow. That is fine: the point is that your investing keeps pace with your income instead of shrinking as a share of it.
Choosing your step up percentage
- Match your raises: if your salary rises about 8% a year, a 5% to 10% step up keeps your SIP at a steady share of income.
- Start smaller, raise more: a ₹3,000 SIP with a 15% step up catches up with a ₹6,000 flat SIP in about 13 years.
- Keep it affordable: a step up that you later pause does less than a smaller one you keep.
- Use a fixed amount if easier: some fund houses let you top up by a rupee amount, such as ₹500 a year, instead of a percentage.
Test a few settings. Raising ₹5,000 by 5% yearly, over a decade at 12%, ends near ₹13,93,471, while the flat version ends at ₹11,61,695.
Step up SIP calculator with inflation
A rupee 20 years from now buys much less than today. To see a step up SIP's value in today's money, use the SIP calculator with inflation, which has a step up box too. At 6% inflation, ₹99 lakh in 20 years is worth roughly ₹31 lakh in today's money. That sounds sobering, but it is the right number to compare with a goal priced at today's rates, such as a child's education.
How to set up a top up SIP
- When you register a new SIP, look for the top up or step up option on the form or app.
- Choose a percentage or a fixed rupee raise and how often, usually yearly.
- Set a cap if you want the raises to stop at a certain amount.
- For an existing SIP without top up, you can start a second SIP in the same fund each year, or stop and restart with a higher amount.
A step up only changes the amount. The units you buy and how they are taxed work exactly as in a normal SIP. Learn the basics on the SIP calculator page.
Reading the year by year table
Below the result, each row of the table gives, the total you have put in so far and the estimated value at year end. Look for the year where the value starts pulling far ahead of the money invested; that is where compounding begins to dominate. If you plan to use part of the money in a particular year, read that year's row rather than the final figure.
To check how a SIP actually performed after some years, use the SIP XIRR calculator. To see what a lumpsum added at the start would do, try the lumpsum calculator.
Mutual fund returns are not fixed. This calculator uses one steady return for every year, which real markets never give. Use it to plan amounts, not to predict results. For personal advice, consult a SEBI registered investment adviser.
Frequently asked questions
What is a step up SIP?
A SIP where the monthly amount rises by a fixed percentage or amount every year. It is also called a top up SIP.
How much does a 10% step up add?
Starting at ₹5,000 and growing at 12% over 20 years, a 10% yearly step up takes the estimate from about ₹50 lakh to about ₹99 lakh. You also invest more, about ₹34.4 lakh instead of ₹12 lakh.
Is a step up SIP better than a normal SIP?
It builds a bigger corpus because you invest more as your income grows. The return rate is the same; only the amounts change.
Can I change the step up later?
Most fund houses let you cancel the top up or start a new SIP with different terms. Rules differ, so check with the fund house or your platform.
Does a step up SIP calculator account for inflation?
This one shows the nominal value. Use the SIP calculator with inflation, which also has a step up box, to see the value in today's money.
What step up percentage is common?
Many investors use 5% to 10% a year, close to typical salary raises. Pick a level you can keep up through bad years.
