Part-prepayment: reduce EMI or reduce tenure?

Last checked: 12 November 2026. Rates, fees and rules change; check the linked sources before you act.

A bonus, a maturing deposit or an inheritance often raises the same question: should this money go into the home loan? If you do prepay, the lender will ask a second question that matters almost as much. Do you want a lower EMI, or do you want to keep paying the same EMI and finish earlier?

What a part-prepayment does

A part-prepayment is any amount you pay on top of your regular EMI. All of it goes to principal, so the balance falls at once and every future month's interest is charged on a smaller amount. The lender then has two ways to rebalance the loan:

• Reduce the tenure. Your EMI stays the same, and because more of each EMI now goes to principal, the loan ends sooner.
• Reduce the EMI. The end date stays the same, and the lender recalculates a smaller EMI for the remaining months.

Both are worked out with the same reducing-balance formula that sets your original EMI (HDFC Bank EMI formula, checked 12 November 2026).

A worked example

Take a loan of ₹60 lakh at an assumed 8.5% a year over 20 years, with an EMI of about ₹52,069. After two years of payments, about ₹57.5 lakh is still owed. You then prepay ₹5 lakh. The rate is an illustration, not an offer from any lender (Showcasia prepayment example, checked 12 November 2026).

• Keep the EMI, reduce the tenure: the loan ends after about 202 months instead of 240, a little over three years early, and you save about ₹15.1 lakh of interest.
• Keep the tenure, reduce the EMI: the EMI falls to about ₹47,542, a saving of about ₹4,500 a month, and you save about ₹4.8 lakh of interest. Figures from the Showcasia prepayment example, checked 12 November 2026.

The same ₹5 lakh saves roughly three times as much interest when you keep the EMI. That gap is typical, because shortening the loan removes whole years of interest at the end, while lowering the EMI keeps the loan running for the full term (Showcasia prepayment example, checked 12 November 2026).

Timing matters more than the choice

Early in a loan most of each EMI is interest, so principal removed then avoids many years of interest. If the same ₹5 lakh were prepaid after 15 years instead of after two, with the EMI kept the same, the saving in this example falls to about ₹2.3 lakh (Showcasia prepayment example, checked 12 November 2026). Our guide to the amortisation schedule shows why the early years carry so much interest.

When reducing the EMI is the better choice

Saving the most interest is not the only goal. A lower EMI can be the right call when:

• your income has fallen or become less certain, and a smaller compulsory payment protects you;
• your floating rate has risen and the EMI is now tight;
• you want to free up monthly cash for school fees, a parent's care or a second loan;
• you plan to keep prepaying, and want the lowest fixed commitment in between.

When reducing the tenure is the better choice

Keeping the EMI and shortening the loan suits you when your budget already handles the EMI comfortably, when you want to be debt-free before retirement, or when the loan currently runs past the age at which your income is likely to drop. It is also the simplest way to turn a one-off sum into a large, certain saving.

Before you prepay

1. Keep an emergency reserve. Money paid into a loan is hard to get back. Most households keep several months of expenses aside first.
2. Check charges. For floating-rate loans to individuals for non-business purposes sanctioned or renewed from 1 January 2026, RBI directions bar prepayment charges (RBI prepayment directions, checked 12 November 2026). Other loans depend on your agreement; see our guide to prepayment penalties.
3. State your choice in writing and keep the acknowledgement.
4. Ask for a new schedule and check that the end date or EMI changed as you asked.
5. Think about tax. Lower interest can mean a smaller interest deduction where one applies to you. Check with a tax professional.
