Home Loan Prepayment: Should You Reduce the EMI or the Tenure?

Every EMI contains interest and principal. In the early years, most of the EMI is interest. A lump-sum prepayment cuts the principal, so all future interest falls.

A worked example

Take a home loan of ₹30 lakh at 9% for 20 years. The EMI is about ₹26,992. After 3 years you pay a lump sum of ₹2 lakh. You have two choices:

Option A: keep the EMI, shorten the tenure

The remaining 204 months fall to roughly 174, so you finish about two and a half years earlier. Total interest saved is about ₹6.2 lakh.

Option B: keep the tenure, reduce the EMI

The EMI falls by about ₹1,900 to roughly ₹25,074, and you save about ₹1.9 lakh in interest.

Both are good, but Option A saves about three times more. Option B helps if you need more monthly cash flow. Try your own numbers with the prepayment calculator.

Before you prepay

• Keep 3 to 6 months of expenses aside first: see the emergency fund guide.
• Check whether your loan is floating or fixed. Floating loans for individuals generally allow free part-prepayment; fixed ones may charge a fee.
• Clear more expensive debt, such as credit card dues, before prepaying a home loan.
• Ask the lender in writing to apply the payment to the principal and to keep the EMI unchanged if you want a shorter tenure. Some lenders lower the EMI by default.
