How to Read Your Home Loan Amortization Schedule

Your bank gives you an amortization schedule with 240+ rows. Here is how to read it, find the interest-principal breakpoint, and use it for prepayment planning.

1.What an amortization schedule shows

An amortization schedule breaks down every EMI into its interest and principal components, month by month. For a ₹50 lakh loan at 8.5% for 20 years (EMI ₹43,391): **Month 1**: ₹35,417 interest + ₹7,974 principal. **Month 120** (year 10): ₹22,849 interest + ₹20,542 principal. **Month 240** (final): ₹305 interest + ₹43,086 principal. The "crossover month" where principal exceeds interest happens around month 130-140 for a typical 20-year loan.

2.The crossover point and why it matters

Before the crossover, more than half your EMI goes to interest — the bank earns more than you repay. After crossover, you're mostly paying down principal. **On a ₹50 lakh 20-year loan at 8.5%, crossover happens in month 136 (year 11.3)**. This means: if you plan to sell the property in year 8, you've paid ₹41.7 lakh in total EMIs but only repaid ₹14.2 lakh in principal. The remaining ₹27.5 lakh went to interest. Understanding this prevents the shock of seeing your outstanding balance after years of payments.

3.Using amortization for prepayment decisions

Look at the interest column in your schedule. In the early years, the interest per month is nearly equal to your EMI. Every ₹1 of principal prepaid in these years saves ₹3-4 in future interest. Strategy: identify months where interest is highest (months 1-60) and prioritize prepayment there. Even ₹50,000 prepaid in month 12 saves more than ₹2 lakh prepaid in month 180.

4.Key takeaway

Your amortization schedule is a roadmap for smart repayment. Look at the crossover month to understand when your payments start meaningfully reducing principal. Use our mortgage amortization calculator to generate your full schedule and identify the optimal prepayment windows.
