Practical Worked Example

An Rs 20,00,000 loan at 9.0% interest amortized over 10 years.

01.Monthly EMI = Rs 25,335.
02.Month 1: Rs 15,000 interest + Rs 10,335 principal reduction.
03.Month 120: Rs 188 interest + Rs 25,147 principal reduction.
04.Total Interest Paid = Rs 10,40,210.
Rs 25,335 / Month (Rs 10.4L Interest)As the principal balance reduces over time, the interest portion shrinks and the principal portion increases each month.

Interpretation & Industry Benchmarks

Amortization schedules illustrate why making prepayments early in the loan tenure saves far more interest than prepaying later.

Early Principal PrepaymentMaximum Interest Savings

Early prepayments eliminate future compounding interest.

Industry Nuance: Lenders front-load interest payments, which is why refinancing late in a loan term offers diminishing returns.

Analytical Limitations

  • Assumes regular on-time monthly payments without late penalties.

Frequently Asked Questions

Why is interest higher at the beginning of the loan?

Because interest is calculated as a percentage of the remaining principal balance, which is at its peak at the start of the loan.
