₹25 lakh loan. ₹27 lakh interest. You read that right — you pay more in interest than you borrowed.
Most people don't realize this until they're 5 years into their EMI payments and the bank statement shows a balance that barely moved. Here's why, and what you can do about it.
The Brutal Math of Home Loans
₹25 Lakh Home Loan at 8.5% for 20 Years
| Metric | Value | |--------|-------| | Loan Amount | ₹25,00,000 | | Interest Rate | 8.5% per year | | Tenure | 20 years (240 months) | | Monthly EMI | ₹21,698 | | Total Payment (240 × ₹21,698) | ₹52,07,520 | | Total Interest | ₹27,07,520 | | Interest as % of loan | 108.3% |
You pay ₹27 lakh in interest on a ₹25 lakh loan. That's 108% of the principal. The bank makes more from your interest than the loan itself.
The Trench Truth: In the first 5 years of a 20-year home loan, approximately 75% of every EMI goes toward interest, not principal. Your loan balance barely moves. This is by design — banks front-load their profit. The amortization schedule is not your friend.

The 15-Year vs 20-Year Dilemma
Should you choose a shorter tenure with higher EMI, or longer tenure with lower EMI?
| Parameter | 15 Years | 20 Years | Difference | |-----------|----------|----------|------------| | Monthly EMI | ₹24,617 | ₹21,698 | +₹2,919/month | | Total Payment | ₹44,31,060 | ₹52,07,520 | -₹7,76,460 | | Total Interest | ₹19,31,060 | ₹27,07,520 | -₹7,76,460 | | Interest Savings | — | — | ₹7.76 lakh |
Choosing 15 years saves ₹7.76 lakh in interest — that's a new car or 2 years of international tuition. The EMI increase is only ₹2,919/month (13.4% more), but the savings are 28.7% of total interest.
The Trench Truth: Always choose the shortest tenure you can afford. The "lower EMI" of a longer tenure is a trap — you feel relief today but pay lakhs more tomorrow. If you can afford ₹24K instead of ₹21K, do it. Your future self will thank you.
The Prepayment Hack: How ₹1 Lakh Saves ₹3 Lakh
Making a one-time prepayment of ₹1 lakh in Year 3 of a 20-year home loan:
| Scenario | Remaining Tenure | Total Interest Remaining | Interest Saved | |----------|-----------------|-------------------------|---------------| | No prepayment | 17 years remaining | ₹22.1 lakh | — | | ₹1L prepayment (reduce tenure) | 14.5 years | ₹18.9 lakh | ₹3.2 lakh | | ₹1L prepayment (reduce EMI) | 17 years | ₹20.4 lakh | ₹1.7 lakh |
Key insight: Always choose "reduce tenure" over "reduce EMI" when making prepayments. Reducing tenure saves nearly double the interest compared to reducing EMI.

| Prepayment | When | Interest Saved | Tenure Reduced | |-----------|------|---------------|----------------| | ₹1 lakh | Year 3 | ₹3.2 lakh | 2.5 years | | ₹1 lakh | Year 5 | ₹2.4 lakh | 2 years | | ₹1 lakh/year | Every year | ₹12+ lakh | 7+ years | | ₹5 lakh | Year 3 | ₹14+ lakh | 8+ years |
