SIP Step-Up Calculator
A Step-Up SIP (also called Top-Up SIP) lets you increase your monthly investment amount by a fixed percentage every year. This mirrors salary increments — as your income grows, so does your investment. The compounding effect of both returns and increasing contributions creates a significantly larger corpus than a flat SIP.

Step-Up SIP: The Power of Increasing Contributions
A flat SIP of ₹5,000/month at 12% for 20 years grows to approximately ₹49.9 lakh. But with a 10% annual step-up, the same plan grows to over ₹1.49 crore — nearly 3x more, despite starting with the same ₹5,000 initial investment. The difference is the compounding effect of increasing contributions.
The logic is simple: if you get a 10% salary increment every year, investing the same percentage of your salary means your SIP should also increase by 10% annually. Step-Up SIP automates this discipline, ensuring your investment pace keeps up with your lifestyle inflation.
Most major mutual fund platforms including HDFC MF, SBI MF, and Zerodha Coin support Step-Up SIP mandates. You can set the increment as a fixed amount (e.g., ₹500/year) or a fixed percentage (e.g., 10%/year). This calculator uses the percentage method.
