What drives the corpus
- Time in the market matters more than the monthly amount
- A yearly step-up of 10% can raise the final corpus substantially
- Expense ratios reduce returns every year — direct plans cost less
- Assumed returns should be conservative for planning
Tax on SIP redemptions
| Fund type | Short-term | Long-term |
|---|---|---|
| Equity funds (≥ 65% Indian equity) | ≤ 12 months: 20% | > 12 months: 12.5% above ₹1.25 lakh |
| Debt funds (bought from April 2023) | Slab rate | Slab rate |
| Other funds (hybrid, FoFs, international) | Slab rate (≤ 24 months) | 12.5% (> 24 months), depending on type |
Worked example: 10-year SIP
- 1₹10,000 a month for 10 years (120 instalments) at an assumed 12% annual return (1% monthly).
- 2Future value = ₹10,000 × [(1.01^120 − 1) ÷ 0.01] × 1.01 ≈ ₹23,23,391.
- 3Amount invested = ₹12,00,000; estimated gain ≈ ₹11.2 lakh.
Corpus ≈ ₹23.2 lakh, before tax on redemption.
