A step-up SIP calculator shows what a SIP could grow into when you raise the instalment every year, usually by a fixed percentage in step with your pay rises. Enter the SIP you can start with, the yearly step-up, the return you expect and how long you’ll invest. It adds up every instalment month by month, so the bigger instalments of later years are counted correctly.
For a flat monthly amount, use the SIP calculator. To find the starting SIP a target needs, try the goal SIP calculator.
Each instalment is invested at the start of its month and compounds until the end of the plan. Here’s the formula with your numbers plugged in:
FV = P × [(1 + i)n − 1] ÷ i × (1 + i)
That’s for a flat SIP. With your 10% step-up, each year’s instalments compound for their own remaining time; added up month by month that’s ₹1,86,31,383 (₹1.86 Cr).
Why not just r ÷ 12? Fund returns are quoted as yearly compounded growth (CAGR). Converting with (1 + r)1/12 − 1 makes twelve monthly steps add up to exactly 12%. Dividing by 12 would quietly assume 12.68% a year and overstate your returns.
What ₹10,000 a month could grow to at 12% a year, with and without a yearly step-up:
| Time period | Flat SIP | 5% step-up | 10% step-up |
|---|---|---|---|
| 10 years | ₹22.4 L | ₹26.94 L | ₹32.69 L |
| 15 years | ₹47.59 L | ₹61.91 L | ₹82.75 L |
| 20 years | ₹91.99 L | ₹1.28 Cr | ₹1.86 Cr |
| 25 years | ₹1.7 Cr | ₹2.48 Cr | ₹3.94 Cr |
Most of the extra comes from investing more. Over 20 years the 10% step-up puts in ₹68.73 L against ₹24 L for the flat SIP, and ends at ₹1.86 Cr rather than ₹91.99 L. A step-up suits a rising income; if you can afford a bigger SIP today, starting higher gives the money longer to compound. For the full comparison, including when a flat SIP is the better choice, read step-up SIP vs regular SIP.
Yes. Fund houses use both names for a SIP whose instalment rises automatically at set intervals, usually once a year by a fixed percentage or amount, so your investing keeps pace with a rising income.
Month by month. Each instalment is invested at the start of its month and grows at the monthly equivalent of your annual return, and at the start of every year the instalment rises by the step-up percentage. The calculator adds up what every instalment grows to by the end of the plan.
At 12% a year, ₹10,000 a month grows to about ₹92 lakh in 20 years. Raising it by 10% every year takes it to about ₹1.86 crore, roughly double, though you also invest ₹68.7 lakh instead of ₹24 lakh.
One you can keep up, close to the pay rise you expect each year; 5% to 10% is common. At 10% a year your instalment roughly doubles every seven years.
Not if you can afford the bigger SIP. Money invested earlier compounds for longer, so a flat SIP that puts in the same total from day one ends higher. A step-up suits a tight budget today and a growing income tomorrow.
