Home loan balance transfer: when is it worth it?
By the LoanReveal team · Updated 13 October 2026 · 5 min read
Short answer: a balance transfer is usually worth it when the new rate is meaningfully lower (often 0.5% or more), plenty of years are left, and the savings comfortably beat the switching costs. Always ask your current bank for a lower rate first; it may be cheaper than moving.
On ₹35 lakh with 15 years left, moving from 9.25% to 8% saves about ₹4,27,627 after costs. Moving to 8.5% still saves about ₹2,44,367.
What a balance transfer costs
- Processing fee at the new bank, often up to about 0.5% to 1% of the loan, plus 18% GST. Some banks waive it on offers.
- Legal and valuation charges for checking the property again.
- Stamp duty on the new mortgage documents, depending on your state.
- Foreclosure charge at your current bank: zero on floating-rate home loans to individuals (RBI doesn't allow it), but fixed-rate loans may carry one.
- Your time: paperwork, visits, and collecting documents from the old bank.
Worked example
₹35 lakh outstanding at 9.25%, 15 years left. New lender charges a 0.5% fee plus about ₹15,000 in other costs:
| Switching costs (incl. GST) | ₹35,650 |
| New rate 8%: interest saved | ₹4,63,277 |
| New rate 8%: net saving | ₹4,27,627 |
| New rate 8%: EMI lower by | ₹2,574 a month |
| New rate 8%: costs recovered in | 10 months |
| New rate 8.5%: net saving | ₹2,44,367 |
| New rate 8.5%: costs recovered in | 17 months |
The bigger the rate gap and the longer the remaining tenure, the more you save. With only a few years left, the same gap may barely cover the costs.
First, ask your current bank
Many banks will lower your rate to what new customers get, for a one-time conversion fee that is usually much smaller than the cost of moving. Write to your bank, mention the rate you've been offered elsewhere, and ask for a rate revision. If they agree, you save most of the benefit without any paperwork.
Watch out for
- Teaser rates that rise after a year or two. Check the spread over the benchmark (for example, repo rate + 2.5%), not just today's rate.
- Bundled insurance added to the new loan. It is usually optional; ask for it to be removed or priced separately.
- A longer tenure on the new loan. Keep the same remaining tenure, or the lower EMI may hide extra interest.
- Top-up offers bundled with the transfer. Borrow more only if you really need it.

Frequently asked questions
How much rate difference makes a balance transfer worthwhile?
There's no fixed rule, but a gap of about 0.5% or more with many years left is often worth checking. The real test is whether the interest saved clearly beats all switching costs; a calculator gives the answer for your loan.
Is there a charge for closing my old home loan?
Not for floating-rate home loans taken by individuals for non-business purposes: RBI doesn't allow foreclosure or prepayment penalties on them. Fixed-rate loans may carry a charge; check your loan agreement.
Does a balance transfer affect my credit score?
The new lender's credit check may cause a small, temporary dip. Closing the old loan properly and paying the new EMIs on time keeps your score healthy.
