Why a small home-loan prepayment saves lakhs

Where your money goes in a long loan

In the early years of a long home loan, most of each EMI is interest charged on a large outstanding balance. Any extra rupee you pay goes straight to principal — and reducing principal early removes all the future interest that balance would have generated.

The compounding effect of paying early

A prepayment in year 2 avoids interest for the remaining 18 years. The same prepayment in year 15 only avoids interest for 5 years. That is why when you prepay matters more than how much: early prepayments compound their savings over the longest remaining period.

A worked example

On a ₹40 lakh loan at 9% for 20 years, the EMI is about ₹35,989. Add just ₹5,000 a month to every EMI and you typically clear the loan several years early and save well over ₹10 lakh in interest — from money you would otherwise barely notice leaving your account.

Prepay or invest the difference?

Prepaying gives you a guaranteed, tax-free return equal to your loan rate. If you can reliably earn more than that after tax in an investment, investing may win; if not, prepaying is the safer, certain choice. Many people split the difference — prepay some and invest some.

Before you prepay, check

• Charges: floating-rate home loans to individuals usually have no prepayment penalty, but confirm with your lender.
• Liquidity: keep an emergency fund — money put into a loan is hard to take back out.
• Tax: if you claim home-loan interest deductions, factor in the tax benefit you give up.
