Step-Up Comparison: The Cost of Inaction
10y @ 12%| Scenario | Total Invested | Gross Corpus | Post-Tax | In Today's ₹ |
|---|---|---|---|---|
| Flat SIP (0% Step-up) | ₹12.00 Lakh | ₹23.23 Lakh | ₹21.93 Lakh | ₹12.84 Lakh |
| 1% Annual Step-up | ₹12.55 Lakh | ₹24.08 Lakh | ₹22.73 Lakh | ₹13.31 Lakh |
| 5% Annual Step-up | ₹15.09 Lakh | ₹27.87 Lakh | ₹26.36 Lakh | ₹15.43 Lakh |
| 10% Annual Step-up | ₹19.12 Lakh | ₹33.74 Lakh | ₹31.99 Lakh | ₹18.73 Lakh |
*Notice how a 10% annual step-up nearly doubles the real purchasing power compared to a flat SIP.
Statutory Note: In accordance with Finance (No. 2) Act 2024, each SIP instalment represents an independent acquisition lot. All units held for more than 12 months qualify for Section 112A LTCG (12.5% after ₹1.25L exemption); units from the final 12 months are taxed under Section 111A STCG (20%). This assumes a lump-sum complete exit at tenure completion.
