Step-up SIP Calculator
See how raising your SIP a little every year massively grows your corpus.
A step-up SIP (also called a top-up SIP) increases your monthly investment by a fixed percentage every year — usually in line with your salary growth. This calculator shows how that small annual increase can add a substantial amount to your final corpus compared to a flat SIP.
How this calculator works
Enter your starting monthly SIP, the annual step-up percentage, your investment horizon and the expected return. Each year the calculator raises your instalment by the step-up rate and compounds every month, then shows your total invested, estimated returns and maturity value.
The formula
FV = Σ (yearly SIP instalments compounded monthly), with SIP increased by the step-up % each year- FV
- = Maturity value
- Initial SIP
- = First-year monthly amount
- step-up
- = Annual % increase in SIP
- i
- = Monthly return
- n
- = Months
Because there is no single closed-form expression, the value is computed year-by-year: each year's instalments compound to maturity and the instalment grows by the step-up percentage.
Worked example
Maturity value ≈ ₹75+ lakh — roughly 50% more than a flat ₹10,000 SIP, for the same starting amount.
Key benefits
- Aligns investing with rising income
- Beats inflation more effectively than a flat SIP
- Builds a far larger corpus for the same starting amount
- Automatable with most fund houses and platforms
Smart tips
- Set the step-up close to your expected annual salary hike (8–12%)
- Even a 5% step-up meaningfully improves outcomes
- Combine with long tenures to maximise the compounding benefit
- Revisit the step-up rate after big income jumps
