Home Loan Balance Transfer: When Switching Actually Saves Money
Every few months a bank sends you a message about moving your home loan to it at a lower rate. Sometimes that message is worth Rs 14 lakh. Sometimes it costs you Rs 40,000 and saves nothing. The difference is arithmetic, and it takes about ten minutes to do.
With the repo rate at 5.25% and advertised home loan floors clustered between roughly 7.10% and 7.50% at the large lenders, plenty of borrowers who took loans two or three years ago are paying a full percentage point more than a new borrower would today. That gap is what a balance transfer is for. Here is when to take it, and when to ignore it.
Key takeaways
- A gap of 0.50% or more, with 10 or more years left, is usually worth moving. Below 0.25%, or with under five years left, it rarely pays.
- Ask your own lender first. An internal rate reset costs a fee of a few thousand rupees against Rs 35,000 to Rs 50,000 for a full transfer.
- Keep the EMI, cut the tenure. On a Rs 50 lakh loan, holding the old EMI after a switch saves about Rs 14.5 lakh; taking the lower EMI instead saves about Rs 7.5 lakh.
- No foreclosure charge on a floating-rate home loan. The RBI's pre-payment directions apply from 1 January 2026 to loans sanctioned or renewed on or after that date, and floating-rate home loans to individuals were already outside penalty territory.
- The real costs are the new lender's — processing fee, fresh legal and technical valuation, and stamp duty on the new mortgage deed.
Why your rate drifted above the market
Since October 2019 new floating retail loans have been priced off an external benchmark, in practice the repo rate: your rate is repo plus a spread the bank fixed at sanction. When the repo moves, your rate follows within the reset cycle. What does not move is the spread, and that is where the gap opens.
Two borrowers with the same bank can hold repo-linked loans priced 90 basis points apart, purely because one signed when the bank was buying market share and the other did not. Older loans on MCLR or the base rate drift further, because those benchmarks pass on rate cuts slowly and incompletely. If you have never checked which benchmark your loan uses, that is the first thing to look up on your statement.
The arithmetic, on a real loan
Take Rs 50 lakh outstanding with 18 years left, at 8.75%, and a new lender offering 7.60%.
| Scenario | EMI | Interest still to pay | Tenure |
|---|---|---|---|
| Stay at 8.75% | Rs 46,040 | Rs 49.45 lakh | 18 years |
| Switch to 7.60%, take the lower EMI | Rs 42,540 | Rs 41.89 lakh | 18 years |
| Switch to 7.60%, keep paying Rs 46,040 | Rs 46,040 | Rs 34.90 lakh | About 15 years 5 months |
The lower-EMI route saves about Rs 7.5 lakh. Keeping the old EMI and letting the tenure shrink saves about Rs 14.5 lakh and ends the loan two and a half years early. Same transfer, same paperwork, nearly double the benefit — the only difference is a box you tick on the application.
What the switch costs
| Item | Typical cost on a Rs 50 lakh loan |
|---|---|
| Processing fee at the new lender | 0.25% to 1%, often capped or waived in a campaign — Rs 5,000 to Rs 25,000 |
| Legal and technical valuation | Rs 3,000 to Rs 7,000 |
| Stamp duty on the fresh mortgage deed | 0.1% to 0.5% by state — Rs 5,000 to Rs 25,000 |
| Documentation, CERSAI, courier | Rs 1,500 to Rs 3,000 |
| Foreclosure charge at the old lender | Nil on a floating-rate home loan to an individual |
Call it Rs 40,000 all in. Against a saving of Rs 3,500 a month, the switch pays for itself in about twelve months, and everything after that is yours. That break-even test — total cost divided by monthly saving — is the whole decision. If the answer is more than 24 months, or more than the time left on your loan, don't move.
Do this before you apply anywhere
- Find your spread. Your rate minus the current repo of 5.25% is what your bank thinks of you. A spread above 2.50% on a good credit profile is worth arguing about.
- Get a competing sanction letter in writing. Not a chat message — a letter with the rate, the fee and the validity date on it.
- Take it to your own lender and ask for a reset. Most banks will reprice an existing loan for a conversion fee, typically a few thousand rupees plus GST, or a small percentage of the outstanding. If they match within 15 basis points, stay: matching costs you a tenth of what moving does.
- Only then transfer, and tell the new lender to keep your EMI and shorten the tenure.
Five traps in the fine print
- The tenure reset. A transfer that quietly stretches your loan back out to 20 years makes the EMI look wonderful and costs more in total interest than staying. Check the sanction letter's tenure, not just its rate.
- Insurance bundled into the loan. A credit-life policy funded by the loan itself adds to the principal and to the interest you pay on it. It may be worth buying — it is rarely worth financing.
- The fee waiver with a string. "Zero processing fee" often depends on buying that policy. Price the two together.
- The gap period. Your old lender releases the property papers after the new one pays off the loan. Track the original title documents by name and get an acknowledgement — this is where files go missing.
- A top-up you did not need. The new lender will offer one at home loan rates. It is cheap money, but it undoes the tenure saving you just booked if you take it for consumption.
When a transfer is the wrong move
In the last five years of a loan you are paying mostly principal, so a lower rate does very little — the fees will usually exceed the saving. If your outstanding is under about Rs 15 lakh, the fixed costs bite the same way. If your income or credit score has fallen since the original sanction, a fresh underwriting can come back at a worse rate than you have now, or with conditions attached. And if the property has an unresolved title question or a pending completion certificate, the new lender's legal check will surface it and stall the file.
One more: if you are within a year or two of clearing the loan anyway, put the money into paying it down rather than into a transfer's fees. Part-prepayment on a floating-rate loan carries no penalty, and it beats a rate cut on a shrinking balance every time.
FAQ
How much rate difference makes a balance transfer worth it?
As a working rule, 0.50% or more with at least ten years remaining. At 0.25% the saving on a Rs 50 lakh loan is roughly Rs 800 a month, and Rs 40,000 of costs takes four years to recover.
Will I have to pay a foreclosure charge to my current bank?
Not on a floating-rate home loan taken by an individual. Fixed-rate loans can still carry a prepayment charge, so check your sanction letter for which one you hold.
Does a balance transfer hurt my credit score?
Briefly and slightly. The new application creates a hard enquiry and the old account closes, both of which nudge the score down for a few months. Paid on time, the new loan restores it.
Can I transfer a loan on an under-construction flat?
Usually yes, if the project has the approvals the new lender needs and the developer's tie-up is in place, but expect more scrutiny and a slower file. Many lenders prefer to wait for possession.
Is an internal rate reset better than switching banks?
Almost always, when the bank offers a competitive number. It costs a conversion fee instead of a fresh set of transfer costs, and there is no property paperwork to move. Use a competing sanction letter as leverage, and switch only if your bank will not come close.
Before you sign
The best time to fix your rate is before you take the loan, not after — how much you borrow and what you put down decide the pricing you are offered. Our guides to the down payment you actually need and to how much loan your salary supports cover that side.
