What is a step-up SIP?
A step-up SIP starts with one amount and increases it every year. It lets your investing keep pace with your income.
How to use this calculator
- Choose a mode: value, goal or time needed.
- Set the starting amount, how often you invest and the expected return.
- Choose whether the yearly increase is a percentage or a fixed amount, and how much.
- Turn on tax or inflation if you want those views.
Worked example
Starting at ₹10,000 a month for 20 years at 12%: a flat SIP invests ₹24,00,000 and grows to ₹91.99 lakh. Raising it by 10% a year invests ₹68.73 lakh and grows to ₹1.86 crore.
Effect of the yearly step-up
₹10,000 a month to start, 20 years, 12% a year.
| Yearly step-up | Invested | Value |
|---|---|---|
| 0% | ₹24 lakh | ₹91.99 lakh |
| 5% | ₹39.68 lakh | ₹1.28 crore |
| 10% | ₹68.73 lakh | ₹1.86 crore |
| 15% | ₹1.23 crore | ₹2.86 crore |
How the calculation works
Instalment in year y = P × (1 + s)y − 1 (or P + s × (y − 1) for a fixed amount); each grows at i per period until the end.
Assumptions
- Constant yearly return; the step-up happens once a year.
- Tax view uses the equity-fund rules described on the SIP calculator page.
