Step-Up SIP Calculator
Calculate returns from step-up SIP with annual top-up. Compare corpus vs regular flat SIP with bar chart and year-wise progression. Free top-up SIP calculator.
M = Σ(year=1 to n) Σ(month=1 to 12) [monthly_sip_year × (1+r)^remaining_months]Each year the monthly SIP grows by the step-up rate. Every monthly contribution compounds at the monthly return rate (annual return ÷ 12) for the remaining months until maturity. This models a top-up SIP that increases annually — more realistic than a flat SIP.
| Symbol | Meaning |
|---|---|
| monthly_sip_year | Initial SIP × (1 + step-up%)^(year−1) |
| r | Monthly return rate (annual return ÷ 12) |
| remaining_months | Months left until end of investment period |

Frequently Asked Questions
Quick answers to common questions
What is a step-up SIP?+
A step-up SIP (also called top-up SIP) increases your monthly investment by a fixed percentage each year. For example, 10% annual step-up on ₹5,000/month grows to ₹5,500 in year 2, ₹6,050 in year 3, and so on.
How is step-up SIP different from regular SIP?+
A regular SIP invests the same amount every month. A step-up SIP increases annually, reflecting salary growth and boosting your final corpus significantly over long tenures.
What step-up rate should I use?+
Many investors use 5–15% annual step-up to match expected salary increments. Our calculator defaults to 10% — adjust based on your income growth expectations.
How much more does step-up SIP earn?+
Over 10 years at 12% returns, a ₹5,000/month SIP with 10% annual step-up can earn ₹3–5 lakh more than a flat ₹5,000 SIP, depending on tenure and rate.
Can I do step-up SIP in mutual funds?+
Yes. Most fund houses offer step-up SIP or top-up SIP facilities. You can also manually increase your SIP amount each year.
What return rate should I assume?+
Equity mutual funds have historically returned 10–12% over long periods. Debt funds may yield 7–8%. Use conservative estimates for planning.
Is step-up SIP better than increasing lumpsum?+
Step-up SIP automates disciplined increases. Both work — step-up SIP is easier to maintain as it happens automatically through your fund.
How is the corpus calculated?+
Each year's monthly SIP compounds monthly at the expected return rate. The formula sums every contribution multiplied by its remaining compounding months.
