Sip Calculator
When you start a monthly Systematic Investment Plan (SIP), it is common to set a fixed amount and let it run for decades. But over time, your salary increases, your household income grows, and inflation goes up. If you do not increase your investment amount accordingly, your financial goals will lag. Enter the Step-Up (or Top-Up) SIP — a simple tweak that will completely transform your wealth-creation journey.
Flat SIP vs Step-Up SIP Comparison Table
| Investment Type | Starting Monthly | Yearly Increase | Total Invested (20 Yrs) | Final Corpus (12% CAGR) |
|---|---|---|---|---|
| Flat SIP | ₹10,000 | 0% (Flat) | ₹24.0 Lakhs | ₹99.9 Lakhs |
| Step-Up SIP | ₹10,000 | 10% every year | ₹68.7 Lakhs | ₹2.07 Crores (Double!) |
The Math Behind Step-Up Compounding
By increasing your SIP by just 10% each year, your monthly contribution goes from ₹10,000 in Year 1 to ₹11,000 in Year 2, and ₹12,100 in Year 3. This matches standard salary increments and builds a massive compounding base. Over a long horizon, it does not just double your investment base; it dramatically accelerates your wealth accumulation velocity.

Key Implementation Tips
- Set it on autopilot: Choose the "Auto-Upgrade" or "Top-Up SIP" checkbox when launching a new SIP online via your broker.
- Link it to your appraisals: Schedule the step-up month to align with your annual salary revision (typically April or July).
- Choose percentages: A 10% annual increase is far superior and easier to manage than a flat ₹1,000 increase over multi-decade horizons.

What is a Step-Up SIP (Top-Up)?
A Step-Up SIP or Top-Up SIP is an investment feature or strategy where you increase your monthly SIP contribution by a fixed percentage (e.g., 10%) or a fixed rupee amount (e.g., ₹1,000) every year. This matches your increasing salary over time.
How much faster does a Step-Up SIP grow your wealth?
Over 20 years at a 12% CAGR, a flat ₹10,000 monthly SIP yields ₹99.9 Lakhs. By stepping up your SIP by just 10% every year, your final corpus becomes a massive ₹2.07 Crores — more than double the wealth, with a very gradual increase in investments.
Is a Step-Up SIP mandatory?
No, it is not mandatory. Most mutual fund portals allow you to set an automatic annual step-up when you initiate the SIP. Alternatively, you can manually start additional SIPs each year as your income increases.
