The Only Rule That Matters
Compare your home loan cost against your expected SIP return. Whichever number is higher — that's your answer. Use our home loan EMI calculator and SIP calculator to check your numbers quickly.
Loan 8.5% → ~8.5% effective cost.
Equity SIP at ~12% CAGR (based on long-term historical averages).
Spread: SIP wins by ~2–3% at 12% returns. At 9–10% returns, the gap disappears.
Based on historical market returns. Estimates for illustration. Actual returns may vary depending on market cycles. Review assumptions periodically.
SIP vs Home Loan Prepayment — Quick Comparison
| Factor | Prepayment | SIP Investment |
|---|---|---|
| Return | Guaranteed — equals loan rate | Market-linked — 10–13% historically |
| Risk | Zero. Saving is certain. | Medium — can underperform for 3–5 yrs |
| Liquidity | None — locked in property | High — redeem in 1–3 business days |
| Best for | Loan > 9%, near retirement | Loan < 9%, 10+ year horizon |
| Outcome | EMI-free early, no corpus | Growing wealth, EMI continues longer |
Short-term market volatility (3–5 years) can significantly impact SIP outcomes. Check latest rates before making decisions.
Real ₹ Example — ₹10,000/month Extra
Base scenario: ₹50 lakh loan · 8.5% rate · 20-year tenure. You can replicate this in our SIP calculator using your own monthly amount and horizon.
At historical 12% returns, SIP beats prepayment — but only by ₹5.5 lakhs over 12 years. That's a thin margin for meaningful market risk. Actual returns may vary. Below 10% returns, prepayment wins outright.
Consistency matters more than timing — trying to wait for market dips often leads to missed investing years.
When Each Strategy Wins
- Loan rate is above 9.5%
- Less than 7 years left on loan
- Retirement is within 10 years
- Income is unstable or variable
- Loan rate is below 8.5%
- 15+ years remain on loan
- You can hold through market crashes
- 80C / NPS limits aren't maxed yet
- You need liquidity as a backup
Before prepaying, ensure you've used key tax-saving investments like ELSS and NPS where applicable.
The Smart Strategy: Split It
⚖️ ₹6,000 SIP + ₹4,000 Prepayment
This remains the most balanced approach for most borrowers at 7–9% loan rates. You get ~₹10.5L in interest savings plus a liquid ₹13.9L SIP corpus after 10 years — combined benefit of ₹24L+.
Pure SIP leaves you exposed if markets deliver 6–8% for a stretch. Pure prepayment leaves no liquid corpus. The split hedges both risks and lets you adjust the ratio each year.
🔨 How to Adjust the Split
4 Mistakes That Cost People Lakhs
-
01
Prepaying before emergency fund exists
Prepaying ₹5L then breaking a FD at penalty rate to fund an emergency. Net loss, guaranteed stress.
Keep 6 months of expenses liquid before any extra repayment. -
02
Reducing EMI instead of tenure
When you prepay, banks offer: reduce EMI or reduce tenure. Reducing EMI saves ₹3K/month now. Reducing tenure saves ₹8–10L in total interest.
Always choose "reduce tenure" unless cash flow is critically constrained. -
03
Stopping SIP when markets crash
Redirecting SIP money to prepayment during a 30% correction is the worst possible timing — you miss the best NAV-averaging period.
Automate SIP. If you must cut, cut prepayment — never SIP during corrections. -
04
Prepaying before maxing 80C and NPS
ELSS saves ₹46,800 in tax immediately for a 30% bracket taxpayer — a 31% guaranteed return before the fund even starts. Ignoring this is expensive.
Exhaust ELSS and NPS deductions first. Prepay with what remains.
- Loan > 9.5%: Prepay. The guaranteed saving beats likely SIP returns at current market uncertainty.
- Loan 7–9%: Split ₹6K SIP + ₹4K prepay. Best risk-adjusted outcome for most borrowers.
- Loan < 7%: Prioritise SIP. Let low-cost debt work in your favour over 15+ years.
- Always reduce tenure, not EMI when making any prepayment to the bank.
- 80C and NPS first: Tax deductions give guaranteed returns that beat any prepayment rate.
If You're Unsure — Do This
Default to a 50-50 split and review yearly. Automate ₹5K to SIP and ₹5K as prepayment. As your loan outstanding drops, gradually shift more toward SIP. Consistency beats optimisation.
