Step Up SIP Calculator
The Step Up SIP Calculator helps you estimate the returns on a SIP where you increase your monthly investment by a fixed percentage every year, instead of keeping it the same throughout. You enter your starting monthly amount, your annual step-up rate, an expected return, and your time horizon, and the calculator instantly shows your total invested amount, your estimated returns, and your final maturity value. It's a quick, free way to see how raising your SIP a little each year can grow your corpus.
What is a Step Up SIP?
A step-up SIP, also called a top-up SIP, is a Systematic Investment Plan in which your monthly contribution rises by a set percentage each year. The idea is simple: as your income grows over time, your investment grows with it. So instead of investing the same amount for the entire tenure, you might start at ₹10,000 a month and increase it by, say, 10 per cent every year. Over a long horizon, this steady annual increase can make a substantial difference to your final corpus.
What is the Step Up SIP Calculator?
The Step Up SIP Calculator is an online tool that estimates the maturity value of a SIP whose monthly amount increases each year. You provide your initial monthly investment, your annual step-up rate, an assumed return, and your tenure, and it works out your total contribution, your estimated returns, and your combined maturity value. It handles the year-by-year maths for you, so you can see the impact of stepping up before you commit. The figures are estimates; actual returns depend on the scheme and market performance.
How Does the Step Up SIP Calculator Work?
Unlike a regular SIP, where the monthly amount stays fixed, a step-up SIP changes every year, so the calculator works it out one year at a time. In each year, the monthly amount is increased by your step-up rate:
Year k monthly amount = P × (1 + g)(k−1)
where P is your starting monthly amount and g is your annual step-up rate. Each year's contributions are then compounded at the expected return to the end of your tenure, using the standard SIP building block:
M = A × ( [ (1 + i)n − 1 ] ÷ i ) × (1 + i)
where A is that year's monthly amount and i is your annual return divided by 12. The calculator applies this to every year, grows each year's contributions forward to maturity, and adds them all together. The important thing to understand is that the step-up compounds: a 10 per cent annual increase on a ₹10,000 start takes your monthly amount to about ₹23,600 by year 10, not ₹20,000, because each year's increase builds on the last.
How to Use the Indiabulls Securities Step Up SIP Calculator
It takes only a few seconds. Enter your starting monthly investment, then set your annual step-up rate, the percentage by which you want to raise your SIP each year. Add an expected annual return; for a long-term equity SIP, an illustrative 10 to 12 per cent is commonly used, though it varies by scheme and market. Choose your tenure in years. The calculator instantly shows your total contribution across the whole period, your estimated returns, and your final maturity value, so you can compare different step-up rates and see how much extra a small annual increase can build.

Step Up SIP Calculation Example
Suppose you start a SIP of ₹10,000 a month, increase it by 10 per cent every year, assume a 12 per cent annual return, and stay invested for 10 years. Because of the annual step-up, your monthly investment grows to about ₹23,600 by the tenth year, and your total contribution over the decade comes to roughly ₹19.12 lakh. With compounding, the estimated corpus could grow to about ₹33.7 lakh. For comparison, a flat SIP of ₹10,000 a month over the same 10 years would total ₹12 lakh in contributions and reach an estimated ₹23.2 lakh, so stepping up adds meaningfully to both what you invest and what you accumulate.
(Note: this is an illustrative example; actual returns depend on the scheme and market performance.)
Step Up SIP vs Regular SIP: How a Top Up SIP Differs
In a regular SIP, your monthly amount stays the same for the entire tenure. In a step-up, or top-up, SIP, it rises by a fixed percentage each year. The regular SIP is simpler and easier to budget for, while the step-up SIP puts more money to work over time and typically builds a larger corpus, as the example above shows. The trade-off is that your outgoings increase each year, so a step-up plan works best when you expect your income to grow. Neither is inherently better; the calculator lets you compare the two so you can choose the approach that fits your finances and your goals.
