A step-up SIP increases your monthly contribution by a fixed percentage every year — typically 5-15%, matching expected salary growth. This nearly painless escalation can grow your final corpus by 30-50% versus a flat SIP, while feeling no more burdensome than a regular SIP.
What is Step-up SIP?
Most people start a SIP in their 20s with whatever they can spare — say ₹5,000/month. Over 25 years, their salary grows 5-10× but the SIP often stays at ₹5,000 because it was set up once and never touched. The result: real (inflation-adjusted) savings drop year over year, and the final corpus is far smaller than it could have been.
Step-up SIP solves this. You commit to increasing your SIP by a fixed percentage every year — usually matched to salary growth (8-10%). The first year you might pay ₹5,000; year 5 it's ₹7,300; year 15 it's ~₹17,000. Each increase is small, but over 20+ years the compounding effect is dramatic.
Most fund houses (Zerodha Coin, Groww, Kuvera, AMC direct platforms) offer step-up as a built-in feature when you set up the SIP. The auto-debit increases automatically each year on the anniversary, with no action from you.
Compounding with annual step-up
Each year's contributions get added to the corpus and compound for the remaining years. Because contributions grow over time, total invested is much higher than a flat SIP — but the corpus grows even more, because later (larger) contributions still compound for several years.

How to use this calculator
Four sliders. The 'flat SIP equivalent' is shown for direct comparison.
Set initial monthly SIP
What you'd start at year 1. Most start in the ₹5K-25K range.
Set annual step-up percentage
10% matches typical Indian salary growth. 5% is conservative; 15% aggressive.
Set expected return
12% for equity, 8-9% for hybrid. Stay realistic — over-optimistic projections lead to under-saving.
Set duration
Step-up SIPs work best on 15+ year horizons where compounding has room to act.
Why step-up beats flat SIP
Salary growth alignment
Your income grows 8-10% per year. Without stepping up SIPs, your savings rate as a % of income falls every year.
Retirement planning
A flat SIP of ₹10K may not be enough; the corpus shortfall is dramatic. Step-up bridges the gap.
Inflation hedge
₹10,000 today buys what ₹3,200 will buy in 20 years. Step-up just keeps pace with inflation in real terms.
Large goal funding
House down payment in 12 years, kid's college in 18 years, retirement in 25 — step-up makes these realistic on a moderate starting income.
