What is a step-up SIP?
A step-up (or top-up) SIP increases your monthly investment by a fixed percentage every year. Because salaries usually rise, this keeps your savings in step with your income. It is one of the simplest ways to build a larger corpus without feeling the pinch.
Value = Σ (monthly SIP × (1 + step-up)year grown at the monthly rate)
Each month’s SIP grows at the monthly rate r = annual return ÷ 12. The SIP rises once a year by the step-up percentage.

Tips for a step-up SIP
- Match the step-up to your raises. A 10% step-up is a sensible start for most salaried people.
- Automate it. Many fund houses and apps let you set the yearly increase when you start the SIP.
- Stay invested through falls. The benefit builds up over many years.
Frequently asked questions
How much step-up should I choose?
Pick a rate close to your expected yearly pay rise, usually 5% to 15%. Do not choose one that strains your budget.
Is a step-up SIP better than a flat SIP?
For the same starting amount, yes, because you invest more over time. The gap grows with the number of years and the step-up percentage.
Can I change my step-up later?
Yes. You can usually modify or stop the step-up through your fund house or app.
Are returns guaranteed?
No. Equity mutual fund returns change with the market. The return here is only an assumption.
