Why Extra Payments Are So Powerful
In any fixed-tenure loan, each EMI you pay covers both principal and interest. In the early years, a disproportionate part of each EMI goes to interest — on a typical home loan, for the first few years, over 70% of each EMI is pure interest. This is why an extra ₹5,000 per month paid early in a 20-year loan can save you lakhs — that money directly reduces the principal, shrinking the base on which future interest is calculated.
Real Example: On a ₹30 lakh home loan at 8.5% for 20 years (EMI: ~₹26,000), paying just ₹5,000 extra per month saves approximately ₹6.5–8 lakh in interest and cuts the tenure by 5–6 years. That ₹5,000/month for 14 years (instead of 20) is the same total cash out — but you become debt-free 6 years earlier.
Two Ways to Apply Extra Payments in India
- Monthly surplus: Transfer ₹500–₹10,000 extra to your loan account each month. Works well if you have consistent extra income or a small surplus after expenses.
- Annual lump-sum prepayment: Use your year-end bonus, tax refund, or festive gifts for a single large prepayment. A ₹1 lakh lump-sum on a ₹30 lakh home loan can save ₹2–3 lakh in interest if done in the first 5 years.
Floating vs Fixed Rate Loans: Prepayment Rules
RBI guidelines (circular RBI/2019-20/225) prohibit prepayment penalties on all floating-rate retail loans. This means you can prepay your home loan, car loan, or personal loan without any additional charge if they're on floating rates. Fixed-rate loans may carry a 1–5% penalty — always verify with your bank before making a large prepayment.
When Extra Payments Are Best vs When to Invest
The break-even question: if your loan costs X% after tax, and you can earn more than X% investing, investing wins over prepayment.
- Credit card debt (36%+ interest): Prepay 100% — no investment consistently beats this.
- Personal loans (12–18%): Prepay first — low-risk investments don't match this rate.
- Home loans (8–9.5%): After Section 24(b) deduction, effective rate is ~6–7%. Equity SIPs over 10+ years historically return 12–14%. If you have a long horizon and risk tolerance, investing may slightly outperform prepayment. But prepayment gives a guaranteed, risk-free return equal to your interest rate.
