Step-Up SIP Calculator
Calculate returns when you increase your SIP amount each year (step-up/top-up SIP).
About this calculator
The Step-Up SIP Calculator projects the corpus from a SIP that rises each year. Give it the starting instalment, the yearly increase, an expected return and the number of years, and it shows the final corpus, total invested, wealth gained, the SIP amount in the last year and how much more you end up with than with a regular SIP.
It is a quick way to see the effect of annual top-ups on goals such as retirement, a child's education or a house.
How to use it
- Enter the Initial Monthly SIP.
- Enter the Annual Step-Up percentage.
- Enter the Expected Return and the Investment Period.
- Press Calculate Step-Up SIP and read the results.
Formula
Each year's monthly SIP is the previous year's multiplied by (1 + step-up). Instalments compound monthly at return ÷ 12. The total corpus is the sum of all instalments' future values.
Worked example
₹5,000 a month, 10% step-up, 12% return, 20 years
| Total corpus | ₹99.44 L |
| Total invested | ₹34.36 L |
| Wealth gained | ₹65.08 L |
| SIP in year 20 | ₹30,580 a month |
| Regular SIP corpus | ₹49.96 L |
| Extra from step-up | ₹49.49 L |
A ₹5,000 SIP becomes ₹30,580 a month by year 20. The extra effort roughly doubles the outcome.
Tips and common mistakes
- Pick a step-up you can sustain even in a lean year.
- Pair step-up with an annual review of your goal.
- Stepping up early has more impact than stepping up late.
- Avoid stopping the SIP when markets fall.
- Keep the return assumption modest.
Frequently asked questions
What is the final-year SIP?
It is the monthly amount in your last year, after all yearly increases. It shows what the plan demands of you later.
How much does a 10% step-up add?
For a 20-year plan at 12%, it roughly doubles the corpus compared with a flat SIP.
Is a step-up better than a larger flat SIP?
It is easier to afford because the increase comes from your rising income.
Can I step up by a fixed amount?
This tool uses a percentage. For a fixed-amount increase, estimate with an equivalent percentage.
What if my income does not grow?
Use a smaller step-up or 0% and compare.
Are the figures in lakhs?
Large results are shown in lakhs (L) and crores (Cr).
