What is a step-up SIP calculator?
A step-up SIP calculator projects returns when your monthly investment increases by a fixed percentage every year—often called a top-up or step-up SIP. Many investors raise their SIP when income grows; this tool models that pattern.
You set starting monthly amount, annual step-up rate, expected return, and tenure. The result shows total capital deployed, estimated gains, and maturity value across the full schedule.
Why use a step-up SIP calculator?
Flat SIP math understates what you might accumulate if you plan to increase contributions alongside salary hikes. A step-up model captures that discipline more realistically.
- See how a 10% annual SIP increase changes your corpus versus a flat SIP.
- Plan top-up percentages before starting a mandate with your AMC.
- Compare step-up outcomes against a standard <a href="/calculators/sip/">flat SIP</a> or <a href="/calculators/lumpsum/">lumpsum</a> for the same starting capital.
How does this calculator work?
Each month, the current SIP amount is invested and compounded at the effective monthly return (same conversion as the flat SIP calculator). At the start of each new year, the monthly SIP increases by your step-up percentage.
Total invested is the sum of every monthly payment across the tenure—not simply starting SIP × months.
Quick illustration
Start at ₹25,000 per month with a 10% annual step-up and 12% return over 10 years. Year one deploys ₹25,000 monthly; year two deploys ₹27,500 monthly, and so on. The maturity value exceeds a flat ₹25,000 SIP because later, larger contributions have fewer years to compound but the total capital deployed is also higher.
How to use this step-up SIP calculator
Enter starting monthly investment, expected return (p.a.), tenure in years, and annual step-up (%). Set step-up to 0% to match a flat SIP baseline.
What this calculator does not include
Step-up timing assumes increases at yearly boundaries. Real mandates may step up on anniversary dates with different rules. Fees, taxes, and return volatility are not modeled.
Frequently asked questions
What is a good annual step-up percentage?
Many planners suggest 5–15% aligned with expected income growth. There is no single correct number—it should match what you can sustain.
How is this different from the flat SIP calculator?
The flat SIP calculator keeps the monthly amount constant. This tool increases the monthly amount each year by your chosen step-up rate.
Can I set step-up to zero?
Yes. At 0% annual step-up, results align with a standard flat SIP for the same starting amount, tenure, and return.
