Prepaying Your Home Loan After the Repo Hike: Cut the EMI or the Tenure?

A Bengaluru family three years into a home loan gets two messages in the same month. The first is from the bank: the repo rate has gone up, and the loan's interest rate will reset at the next review. The second is from the employer: an annual bonus of Rs 5 lakh has been credited. The obvious idea is to put the bonus into the loan. The less obvious question is what to ask the bank to do with it.

When a borrower makes a part-prepayment, the loan can be adjusted in one of two ways: keep the EMI the same and shorten the remaining tenure, or keep the tenure the same and lower the EMI. The choice changes how much interest is paid over the rest of the loan, sometimes by several lakh rupees. This guide works through one illustrative loan, before and after a 25 basis point rise in the lending rate, to show how each choice plays out.

The short answer. On our illustrative Rs 60 lakh, 20 year loan, a Rs 5 lakh part-prepayment at the start of year four, after the rate moves from 8.5 percent to 8.75 percent, cuts remaining interest to about Rs 39.0 lakh if the borrower keeps the EMI and shortens the tenure, against about Rs 47.2 lakh if the borrower keeps the tenure and lowers the EMI. Keeping the EMI saves more interest. The trade-off: a lower EMI frees up monthly cash and leaves more room if income falls, so a household with a thin buffer may reasonably prefer it, while a household with steady surplus income gains more from a shorter tenure.

What did the RBI decide in October 2026?

The Reserve Bank of India's monetary policy statement records that the Monetary Policy Committee, at its meeting from 5 to 7 October 2026, raised the policy repo rate by 25 basis points to 5.50 percent. The standing deposit facility rate was set at 5.25 percent, and the marginal standing facility rate and the Bank Rate at 5.75 percent. The committee described its stance as calibrated tightening.

For a borrower, the repo rate matters because a floating rate home loan may be linked to an external benchmark such as the repo rate. If yours is, a rise in the benchmark can feed into your rate at the reset date set out in the loan agreement. How much of the change reaches your loan, and when, depends on your lender and your sanction terms, so check the reset clause rather than assume. Our earlier report on the RBI's move to a 5.50 percent repo rate covers the decision in more detail.

How does a 25 basis point rise change our illustrative loan?

To keep the arithmetic clear, we use one example throughout. It is an illustration, not a market quote. A buyer takes a Rs 60 lakh loan for 20 years, or 240 months, at 8.5 percent a year. By our calculation, the EMI is about Rs 52,069. After 36 EMIs, the outstanding principal is about Rs 56.09 lakh, with 204 months left.

Now assume the full 25 basis points pass through, so the rate becomes 8.75 percent at that point. The lender can adjust the loan in one of two ways. If the EMI stays at Rs 52,069, the remaining tenure stretches from 204 months to about 212 months, by our arithmetic. If the tenure stays at 204 months, the EMI rises to about Rs 52,922, an increase of roughly Rs 852 a month.

Lengthening the tenure keeps the EMI unchanged, which is convenient, but in this example it adds about Rs 2.4 lakh more interest than raising the EMI would, by our arithmetic. Our explainer on choosing a higher EMI or a longer tenure after a rate rise looks at that choice on its own.

What happens if you prepay Rs 5 lakh?

A Rs 5 lakh part-prepayment at the start of year four brings the outstanding principal down from about Rs 56.09 lakh to about Rs 51.09 lakh. The interest on every later EMI is calculated on this smaller balance, which is why prepaying early in a loan has a large effect.

With the balance at Rs 51.09 lakh and the rate at 8.75 percent, the two choices diverge sharply. Keeping the EMI at Rs 52,069 clears the loan in about 173 months instead of 204, by our arithmetic. Keeping the tenure at 204 months lowers the EMI to about Rs 48,204.

The table below compares five paths for the same loan from the start of year four, all from our own calculation on the assumptions above.

Two points stand out. First, a Rs 5 lakh prepayment with the EMI kept more than offsets the rate rise in this example: interest still to pay falls to about Rs 39.0 lakh, compared with about Rs 50.1 lakh had rates not changed at all. Second, the same Rs 5 lakh saves about Rs 8.2 lakh more in interest when used to shorten the tenure rather than to lower the EMI.

Why does an early prepayment save so much interest?

The answer lies in how an EMI is split. Each month, the lender first charges interest on the outstanding balance, and whatever is left of the EMI goes towards the principal. Early in a loan, the balance is large, so most of the EMI goes to interest.

In our example, the first EMI of about Rs 52,069 at 8.5 percent includes about Rs 42,500 of interest on the full Rs 60 lakh, by our arithmetic. Even at the start of year four, after the rate moves to 8.75 percent, the interest part of the month 37 EMI is about Rs 40,900, and only about Rs 11,169 reduces the principal.

A Rs 5 lakh prepayment changes that split at once. On the lower balance of about Rs 51.09 lakh, the interest part of the next EMI falls to about Rs 37,254, so about Rs 14,815 goes to principal. If the EMI is kept, that larger principal share repeats and grows every month, which is why the tenure shrinks so quickly. If the EMI is lowered, the saving is spread out as a smaller monthly payment instead, and the loan runs for the full remaining period.

The same logic explains why a prepayment late in a loan has less effect. By then the balance is smaller and most of each EMI is already going to principal.

Should you keep the EMI or cut it?

The arithmetic favours keeping the EMI and shortening the tenure. But arithmetic is not the only test. A home loan is a long monthly commitment, and the right choice depends on how secure the household's income is and how much cash it keeps aside.

Keeping the EMI suits a borrower with steady income and an emergency fund already in place. Every rupee of the prepayment then works to cut the number of future EMIs. Cutting the EMI suits a borrower who expects expenses to rise, such as a child's school fees or a parent's care, or whose income varies. The lower EMI of about Rs 48,204 in our example frees close to Rs 3,865 a month, which can be held as a buffer.

Some borrowers split the difference: they ask for the lower EMI, then continue to pay the old amount voluntarily when they can. Whether a lender allows that flexibly, and how extra payments are credited, varies, so ask before you rely on it.

What should you check with your lender before prepaying?

A part-prepayment is simple to make, but the details sit in your loan agreement and the lender's policy. Before paying, get clear answers in writing on how the payment will be applied and what the revised schedule will look like.

Prepayment charges are one item to confirm. Our guide on prepayment charges on floating rate home loans explains the position for individual borrowers. Use this checklist:

1. Confirm your loan's benchmark and the next reset date in the sanction letter.
2. Ask what the new rate will be after the reset, and from which EMI it applies.
3. Ask whether any prepayment charge or minimum amount applies to your loan.
4. Choose in writing whether the prepayment should reduce the EMI or the tenure.
5. Pay from your own account so the payment is traceable.
6. Get a revised repayment schedule and check the new balance and months left.
7. Keep an emergency fund in place before putting surplus cash into the loan.

What do Bengaluru home loan borrowers ask about part-prepayment?

Is it better to reduce EMI or tenure after a part-prepayment?

Reducing tenure usually saves more interest. In our illustrative Rs 60 lakh loan at 8.75 percent, a Rs 5 lakh prepayment with the EMI kept leaves about Rs 39.0 lakh of interest, against about Rs 47.2 lakh if the EMI is lowered instead. A lower EMI, though, gives more monthly breathing room.

What did the RBI do to the repo rate in October 2026?

The RBI's Monetary Policy Committee, meeting from 5 to 7 October 2026, raised the policy repo rate by 25 basis points to 5.50 percent and set its stance as calibrated tightening. Floating rate home loans linked to the repo rate may reset higher, depending on each lender's terms.

How much does a 25 basis point rise add to a home loan EMI?

It depends on the balance and months left. In our example, an outstanding Rs 56.09 lakh with 204 months left sees the EMI rise from about Rs 52,069 to about Rs 52,922 at 8.75 percent. If the EMI is kept instead, the tenure stretches to about 212 months.

Does a small part-prepayment make a difference?

It can. In our example, a Rs 5 lakh prepayment at the start of year four, with the EMI kept, shortens the remaining tenure from 204 months to about 173 months at 8.75 percent. The earlier in the loan a prepayment is made, the larger the effect tends to be.
