What is a Step-up SIP Calculator?
A step-up SIP (also called a top-up SIP) increases your SIP amount by a fixed percentage at regular intervals, usually once a year, so your investments grow along with your income.
This calculator shows how much more you could build by stepping up, compared with keeping the same SIP amount throughout.
How it helps you
- See the impact of raising your SIP every quarter, half-year or year.
- Know what your monthly SIP will be in the final year before you commit.
- Compare a step-up plan with a flat SIP to see the extra value created.
- Plan increases that match expected salary or business growth.
How it is calculated
Value = Σ (instalmentₖ × (1 + i)^(months left)), instalment rises by s% every step
- instalment
- Starting SIP amount, raised by the step-up percentage at each step
- s
- Step-up percentage per step (quarter, half-year or year)
- i
- Monthly rate = expected yearly return ÷ 12 ÷ 100
- months left
- Months each instalment stays invested until the end
Each month's instalment is invested at the start of the month and compounds monthly.
You start a ₹10,000 monthly SIP, increase it by 10% every year, and invest for 10 years at an expected 12%.
- 1Year 1: ₹10,000 a month; Year 2: ₹11,000; Year 3: ₹12,100 … Year 10: about ₹23,579
- 2Total invested over 10 years ≈ ₹19,12,491
- 3Each instalment grows at 1% a month until the end of year 10
Estimated value ≈ ₹33,74,326, compared with about ₹23,23,391 for a flat ₹10,000 SIP.

Frequently asked questions
How much should I step up my SIP?
Many investors match the increase to their expected yearly raise, for example 5–10% a year. Choose an amount you can keep up comfortably.
Can I set up a step-up SIP with any fund?
Most fund houses offer a top-up option when you register the SIP. Availability and the minimum top-up amount depend on the scheme.
Is quarterly step-up better than yearly?
A smaller quarterly increase and a larger yearly increase can lead to similar results. The calculator sets typical defaults (2.5% quarterly, 5% half-yearly, 10% yearly) so you can compare.
Does stepping up change the risk?
No. It changes how much you invest, not where you invest. The risk depends on the fund you choose.
Are the results guaranteed?
The result is an estimate based on a constant rate. Actual market returns change every year and are not guaranteed.
