Social feeds love step-up SIP screenshots: start with ₹2,000/month, raise contribution each year, assume a glossy CAGR, and out pops ₹2 crore+ at retirement. The math is often arithmetically correct and economically fragile. This piece puts assumptions up front so you can stress-test any headline corpus.
What a step-up SIP actually models
You invest S₀ in month 1, then increase by fraction g each year (or on a schedule), while the portfolio compounds at rate r with volatility in real life. Spreadsheets usually use constant r—markets do not.
Sensitivity: CAGR ±2% changes everything
Over 25–30 years, moving assumed CAGR from (say) 10% to 8% can shave tens of percent off terminal value—sometimes more than the step-up itself added. Always run three scenarios: pessimistic / base / optimistic.
Inflation: nominal crore ≠ retirement spending
A ₹2 crore nominal figure in 2045 buys less than the same number suggests today. Pair SIP plans with inflation and longevity checklist.
Income floor vs growth sleeve
Step-up SIPs are growth equity/hybrid tools. For sleep-at-night floors, many households still use PPF/EPF-like sleeves—see PPF income framing and PPF limits.
Gold as diversifier (optional)
If you worry about equity drawdowns in the same decade you retire, understand gold wrappers—digital gold vs gold ETF—rather than doubling equity risk blindly.

Bottom line
Step-up SIPs are a discipline hack, not a prophecy. Disclose your CAGR, step-up %, fee drag, and inflation whenever you share a corpus screenshot—or ignore the screenshot entirely and build your own model.
