What is the Step-Up SIP?
A step-up SIP (or top-up SIP) raises your monthly instalment by a set percentage every year, usually in line with your salary increment. Because the later, larger contributions still get years of compounding, a modest 10% annual step-up often produces roughly double the wealth of a flat SIP over 20 years — without ever feeling like a sacrifice.
Formula & worked example
Each year's SIP compounds monthly, then the instalment rises:
SIPyear+1 = SIPyear × (1 + step%)
Worked example: ₹10,000/month at 12% for 20 years with a 10% annual step-up grows to roughly ₹1.99 crore on about ₹68.7 lakh invested. A flat ₹10,000 SIP over the same period reaches only about ₹99.9 lakh — the step-up adds nearly ₹99 lakh, doubling the outcome.
How to use this step-up sip calculator
- Enter the SIP you can start with today, not what you hope to afford.
- Set the step-up near your expected annual increment — 10% is realistic for most salaried investors.
- Use 10–12% for diversified equity funds; 7–8% for hybrid or debt.
- Compare "Extra vs Flat SIP" to see what the step-up alone contributes.
Smart tips
- Most fund houses let you automate a top-up SIP at registration, so the increase happens without you deciding again each year.
- Time the step-up to your appraisal month — raising the SIP before the extra salary reaches your spending habits is painless.
- Even a 5% step-up meaningfully beats a flat SIP; you do not need an aggressive number to benefit.
- Never step up beyond what you can sustain in a bad year — a paused SIP costs more than a smaller consistent one.
Frequently asked questions
What is a step-up SIP?
A SIP where the monthly amount rises automatically by a fixed percentage each year, typically matching salary growth. It captures more compounding without a big upfront commitment.
Is a step-up SIP better than a regular SIP?
For a long horizon, substantially. A 10% annual step-up on a 20-year SIP roughly doubles the corpus versus a flat SIP with the same starting amount.
Can I change or stop the step-up later?
Yes. Step-up instructions can be modified or cancelled at any time, and pausing the increase does not affect units already bought.
What step-up percentage should I choose?
Match your realistic annual increment — usually 8–12%. Choosing a number you cannot sustain leads to cancelled SIPs, which defeats the purpose.
