How the SIP Step Up Calculator Works
This calculator projects the maturity value of a step-up (top-up) SIP — a Systematic Investment Plan where your monthly contribution increases by a fixed percentage each year. Enter your initial monthly SIP, the annual step-up rate, the expected return and the tenure, and it returns your total invested, the estimated returns and the final corpus.
The Formula
The tool compounds month by month. Each month the balance grows by the monthly return rate after the new contribution is added:
Balance = (previous balance + monthly SIP) × (1 + return ÷ 12)
At the start of every new year, the monthly SIP is raised by the step-up percentage:
New monthly SIP = previous monthly SIP × (1 + step-up rate)
From the running totals:
- Total invested = sum of every monthly contribution
- Estimated returns = maturity value − total invested
Worked Example
Suppose you start with ₹10,000 per month, step up by 10% each year, expect a 12% annual return, and invest for 15 years:
- Year 1 SIP = ₹10,000/month; Year 2 = ₹11,000; Year 3 = ₹12,100, and so on
- Total invested ≈ ₹38,12,698
- Maturity value ≈ ₹86,83,849
- Estimated returns ≈ ₹48,71,152
A flat ₹10,000 SIP over the same 15 years at 12% would mature near ₹50,45,760 — the step-up adds over ₹36 lakh.
Step-Up SIP Growth (₹10,000 start, 10% step-up, 12% return)
| Tenure | Total invested | Maturity value |
|---|---|---|
| 5 years | ₹7,32,612 | ₹9,84,570 |
| 10 years | ₹19,12,491 | ₹33,74,326 |
| 15 years | ₹38,12,698 | ₹86,83,849 |
| 20 years | ₹68,73,000 | ₹1,98,88,715 |
Why Step Up Your SIP
- Beats inflation and lifestyle creep: raising your SIP yearly keeps your saving rate roughly constant against a rising salary.
- Compounds the contributions, not just the returns: larger later instalments still have years to grow.
- Easy to automate: many fund platforms let you set an automatic annual top-up.
Important Notes
- This calculator assumes a constant return rate and start-of-month investing; real returns vary and can be negative in any year.
- Figures are nominal, pre-tax and pre-fee — expense ratios, exit loads and capital-gains tax reduce the in-hand amount.
- Set the step-up rate to a level you can realistically sustain each year.
For a fixed monthly SIP, use the standard SIP calculator; to plan a withdrawal phase, see a SWP calculator.
Frequently asked questions
What is a step-up SIP?+
A step-up (or top-up) SIP is a Systematic Investment Plan whose monthly contribution increases by a fixed percentage every year. It lets your investing keep pace with rising income and builds a much larger corpus than a flat SIP over the same period.
How is a step-up SIP calculated?+
The calculator runs month by month. Each month the running balance and the new contribution earn the monthly return rate, and at the start of every new year the monthly amount is increased by the step-up percentage. The final balance is the maturity value.
How much extra does a 10% step-up SIP add?+
Investing ₹10,000 a month with a 10% annual step-up at a 12% return for 15 years grows to about ₹86,83,849, versus roughly ₹50,45,760 for a flat ₹10,000 SIP — over ₹36 lakh more, because each year's contributions are larger.
Should the step-up rate match my salary hike?+
A common approach is to set the step-up close to your expected annual salary increase (often 5% to 10%) so the higher SIP stays affordable. You can choose any rate; a higher step-up builds a bigger corpus but requires you to commit more cash each year.
Does this calculator guarantee returns?+
No. Mutual fund and market-linked returns are not guaranteed and vary year to year. The return rate you enter is an assumption for projection only; actual results can be higher or lower, and the figures are pre-tax and pre-fees.
