Step-Up SIP Calculator
See how increasing your monthly SIP every year builds a bigger corpus than a flat SIP
Direct Answer: A step-up SIP increases your monthly investment every year by a fixed % or ₹ amount, so your later instalments are larger and still have time to compound — building a noticeably bigger corpus than a flat SIP of the same starting amount.

❓ Frequently Asked Questions
What is a step-up SIP?
A step-up SIP (also called a top-up SIP) is a mutual fund SIP where you increase your monthly investment amount every year, either by a fixed percentage or a fixed rupee amount, instead of investing the same amount for the entire tenure.
How much bigger is the corpus with a step-up SIP compared to a flat SIP?
It depends on your SIP amount, tenure, expected return, and step-up rate. Use the calculator above to see the exact difference for your own numbers — for most 10-20 year tenures with a 10% annual step-up, the extra corpus is commonly 20-40% higher than a flat SIP of the same starting amount.
What step-up percentage should I choose?
A common approach is to match your step-up percentage to your expected annual salary increment, typically 8-12% per year. This keeps the increase manageable while still meaningfully growing your corpus over time.
Can I stop or change my step-up SIP later?
Yes. Most fund houses allow you to modify, pause, or cancel a step-up SIP instruction at any time, similar to a regular SIP. Speak with your mutual fund distributor or use your fund house's app/portal to make changes.
Are the returns shown in this calculator guaranteed?
No. The 8%, 10%, and 12% return options are standard illustration rates used for planning purposes only. Actual mutual fund returns are market-linked, vary by scheme and category, and are not guaranteed.
Is a step-up SIP better than a flat SIP for goal-based planning?
For long-term goals like child education, retirement, or a home purchase, a step-up SIP is often more effective because it grows in line with your rising income, helping you close larger goal gaps without straining your monthly budget in the early years.
