Why does 1 extra EMI save so much?
While regular EMIs are mostly interest in early years, 100% of an extra prepayment reduces principal. One extra payment in Year 1 wipes out nearly 5 to 6 months of future principal repayments at once.

Why Does 1 Extra EMI Per Year Make Such a Big Difference?
It often surprises people that paying just one extra EMI each year can shave nearly 5 years off a 20-year loan. Here is the math behind how it works:
The Early Loan Phase is Mostly Interest
Suppose you have a ₹50 Lakh home loan at 8.75% for 20 years. Your monthly EMI is roughly ₹44,186.
In the first year, out of ₹5.3 Lakhs paid in monthly EMIs, over ₹4.3 Lakhs goes towards interest alone. The actual loan balance only drops by ~₹1 Lakh.
100% of an Extra EMI Goes to Principal
When you pay your regular monthly EMI, the bank deducts interest first. But when you make a part-prepayment of 1 extra EMI (₹44,186), 100% of that money directly reduces your principal balance.
Because a regular monthly payment only reduces principal by ~₹7,700, paying ₹44,186 in one go instantly wipes out nearly 5 to 6 months of future principal repayments in a single transaction.
The Compounding Reversal Effect
Home loan interest is recalculated every month on your remaining balance. Once you reduce the principal early:
- The bank can never charge interest on that prepaid amount again.
- Next month, less interest is due, so a slightly larger share of your next regular EMI goes toward principal.
- Repeating this once every year (e.g. from an annual bonus or tax refund) compounds in your favor year after year.
Real Example: ₹50 Lakh Loan @ 8.75%
By paying 15 extra bonus EMIs over the shortened loan period (~₹6.6 Lakhs), you eliminate ~58 regular EMIs at the end (~₹25.6 Lakhs), resulting in a net interest reduction of ~₹14.8 Lakhs and finishing nearly 5 years earlier.
Three Common Prepayment Strategies
Making one additional payment annually, such as using an annual bonus or tax refund.
Adding a small fixed amount (e.g. ₹2,000 to ₹5,000) directly to your monthly EMI.
Paying an occasional lump sum directly towards the principal balance whenever funds are available.
Common Questions
Do banks allow home loan prepayment?
Most banks and housing finance companies in India allow part-prepayments on floating-rate home loans for individual borrowers. Check with your lender for their specific procedures, minimum payment limits, and processing timelines.
Should I reduce my EMI or reduce tenure?
Keeping your EMI the same and reducing the tenure generally results in lower total interest over the life of the loan. Reducing your EMI lowers your monthly commitment but keeps the repayment period longer.
