Key points
- Keeping the EMI and shortening the tenure saves the most interest.
- On a ₹50 lakh loan, ₹5 lakh prepaid after 5 years saves about ₹10.7 lakh by reducing tenure — but only ₹3.9 lakh by reducing EMI.
- Reducing the EMI makes sense if you need cash-flow relief or expect your income to fall.
The two options
When you prepay part of a loan, the lender recalculates it. Either it keeps your EMI the same, so the loan finishes earlier (reduce tenure), or it keeps the end date the same and lowers the EMI (reduce EMI). Many banks default to reducing the tenure; you can usually ask for either.
The numbers
Take a ₹50 lakh home loan at 8.5% for 20 years, with an EMI of ₹43,391. After 5 years, about ₹44.06 lakh is outstanding, and you prepay ₹5 lakh.
| Option | EMI afterwards | Loan ends | Interest saved |
|---|---|---|---|
| No prepayment | ₹43,391 | After 20 years | — |
| Reduce tenure | ₹43,391 | 3 years earlier | ₹10,69,153 |
| Reduce EMI | ₹38,467 | After 20 years | ₹3,86,266 |
Reducing the tenure saves nearly three times as much. The reason: with the same EMI, the lower balance means more of every future EMI goes to principal, so the balance falls faster and faster. Reducing the EMI simply repays the smaller balance at the same slow pace.
When to reduce the EMI instead
- Your monthly budget is tight, or you want room for another goal such as a child’s school fees.
- You expect your income to fall — a career break, or approaching retirement.
- You plan to invest the difference in EMI every month; this can work if you actually do it, but most people do not.
Watch the tenure when rates rise
On floating-rate loans, banks respond to rate increases by extending the tenure while keeping the EMI unchanged. A few rate rises can quietly add years to a loan. Check your remaining tenure every year; if it has grown, a prepayment or a voluntary EMI increase brings it back.
Why reducing the tenure saves so much more
Every EMI first pays that month’s interest; only the rest reduces principal. After a prepayment, the balance — and therefore the monthly interest — is lower. If the EMI stays the same, the extra that is no longer needed for interest goes straight to principal, which lowers next month’s interest further. The effect snowballs, which is why keeping the EMI unchanged ends the loan years early.
If the EMI is reduced instead, that saving is handed back to you every month, and the loan continues at the same pace as before, just on a smaller balance.
How to ask your lender
- State your choice in writing when you make the part-payment; if you do not, most banks reduce the tenure by default.
- Ask for the revised amortisation schedule and check the new end date or EMI.
- On floating-rate loans, recheck the tenure after every interest-rate change — rate rises are usually absorbed by extending the tenure.
- Some lenders allow reducing the EMI only on the next reset date or charge a small fee for a schedule change; confirm before you pay.
A middle path
If you need some cash-flow relief but still want to save interest, reduce the EMI now and increase it again when your income rises, or reduce the EMI after one prepayment and the tenure after the next. The loan prepayment calculator shows both outcomes for any amount, so you can see the cost of the choice before you make it.
Frequently asked questions
Which option does the bank choose by default?
Most Indian banks reduce the tenure and keep the EMI unchanged unless you ask otherwise. Always confirm in writing.
Does reducing the EMI help my loan eligibility?
Yes. A lower EMI reduces your fixed obligations, which can help if you plan to apply for another loan soon. That can be a good reason to choose it.
Can I switch from reduced EMI back to the original EMI?
Usually yes — lenders allow you to increase the EMI voluntarily. Doing so has the same effect as reducing the tenure from that point on.
