About this calculator
Enter the starting monthly amount, how much you will raise it each year, the expected return and the period. The result is shown next to the same SIP without any increase, so you can see what the step-up adds.
How to use it
- Enter the monthly SIP you will start with.
- Choose whether you will raise it by a percentage or by a fixed rupee amount each year, and enter the increase.
- Enter the expected yearly return and the number of years.
- Compare the estimated value with the “same SIP without step-up” line.
The formula
- P
- the monthly SIP in the first year
- s
- the yearly increase as a decimal (10% = 0.10); with a fixed increase, P + amount × (y − 1)
- i
- the monthly return: expected yearly return ÷ 12 ÷ 100
Each instalment is invested at the start of its month, as in the SIP calculator, so a 0% step-up gives exactly the same answer as a normal SIP.
Worked example
₹5,000 a month, raised 10% every year, for 15 years at 12%
- Year 1: ₹5,000 a month. Year 2: ₹5,500. By year 15: ₹18,987 a month.
- Total invested over 15 years: ₹19,06,349.
- Estimated value: ₹43,41,925.
- The same ₹5,000 SIP without any increase would be worth ₹25,22,880, so the step-up adds about ₹18.2 lakh.
What the result means
The step-up line shows how much of the final value comes from raising your SIP. Part of that is simply the extra money you put in; the rest is the return those extra instalments earn.
A step-up that matches your yearly pay rise keeps your savings rate steady as your income grows, without feeling like a big jump in any single year.
Assumptions
- The increase happens once a year, at the start of each new year of the SIP.
- The yearly return is constant and compounds monthly.
- No instalments are missed and nothing is withdrawn.
Limitations
- Market-linked returns are not fixed; the actual value can be much higher or lower.
- Your fund house may round step-up amounts or apply them on a specific date, so real amounts can differ slightly.
- Exit loads, stamp duty and taxes are not included.
Frequently asked questions
How much should I step up my SIP each year?
Many people use their expected pay rise, often 5% to 10%. Try a few values to see how sensitive the result is.
Can I set up a step-up SIP with my fund?
Most Indian fund houses and investment apps offer a top-up or step-up option when you register a SIP. Check the options your platform provides.
Why does a 10% step-up add so much?
Because the larger instalments of the middle years still have many years left to compound. The later increases add less, since they have little time to grow.
