Step-Up SIP Calculator
A 10% yearly SIP step-up can almost double your final corpus versus a flat SIP. See exactly how much faster your wealth compounds.
About this tool

Why "set and forget" is the wrong default
A flat SIP made sense in an era of stagnant salaries. With most professional roles seeing 7–12% annual increments, a flat SIP slowly shrinks as a % of income — meaning your savings rate decays even as your income rises. A step-up SIP defends against this lifestyle drift automatically: each raise routes a fraction into investing before it touches your spending budget.
The "raise + half" rule
Whenever your monthly take-home goes up by X%, raise your SIP by at least X/2 %. Live on the rest. Over a 25-year career, this single discipline often separates retirement-ready savers from "lifestyle inflators" who never quite get there.
Frequently asked questions
Does a step-up SIP really make that much difference?+
Yes — and the longer your horizon, the bigger the gap. A ₹10,000 SIP for 20 years at 12% returns roughly ₹1 crore. The same SIP with a 10% annual step-up returns ~₹2 crores. The reason: each year's extra contribution compounds for the remaining horizon, and that compounding stack is huge.
What is a realistic step-up rate?+
A safe baseline is your expected annual salary increment — typically 7–10% in stable jobs, 10–15% during high-growth career years. The point is to never let lifestyle inflation eat 100% of your raise. If your salary went up 12%, raise your SIP by at least half of that.
When should I start a step-up SIP vs a flat one?+
Always pick step-up when starting fresh — most platforms now offer it as a default toggle. If you have a flat SIP running today, raise the amount manually each year on a fixed date (anniversary, January, after appraisal). The discipline matters more than the mechanism.
Can I have multiple SIPs with different step-up rates?+
Yes, and it can be smart. Run a high step-up on your retirement SIP (since horizon is longest), a moderate one on a 10-year goal, and a flat SIP on a 3-year goal where the compounding window is too short to matter much. Model each goal separately in the calculator.
What if my income drops? Can I pause the step-up?+
Absolutely. The step-up is a target, not a contract. Most fund houses let you pause or modify the SIP anytime. The calculator is for planning — real life adapts. Even hitting 70% of your plan beats not having one.
