Step-Up SIP Calculator
Estimate SIP returns when your monthly investment grows every year with your income.
What is a Step-Up SIP?
A Step-Up SIP, also called a top-up SIP, increases your regular monthly investment at a chosen interval. Most investors use an annual increase because it naturally matches salary increments, bonuses, and rising savings capacity.
A flat SIP is useful for quick planning, but it can understate long-term corpus if you expect your income and monthly investments to grow over time.
Step-Up SIP Formula
Monthly Return = (1 + Annual Return)^(1/12) - 1
Each monthly SIP instalment is compounded until the end of the selected period. The SIP amount increases at the start of year 2, year 3, and so on.
Step-by-Step Example
Example: ₹10,000/month at 12% for 10 years with 10% annual step-up
Starting SIP: ₹10,000 per month
Year 2 SIP: ₹11,000 per month
Year 10 SIP: about ₹23,579 per month
Total Invested: about ₹19.12 lakh
Final Corpus: about ₹32.69 lakh before tax and fees
Percentage vs Fixed Rupee Step-Up
- Percentage step-up: Best when you want investments to grow in line with income. A 10% annual step-up means each year's SIP is 10% higher than the previous year.
- Fixed rupee step-up: Best when you think in salary-hike amounts, such as adding ₹2,000 more to your monthly SIP each year.
- Inflation-adjusted value: Shows what the future corpus may be worth in today's purchasing power.
