The short answer
It is worth it when the rate cut is large enough, and enough years remain, for the EMI savings to beat the switching costs. Moving ₹40 lakh with 15 years left from 9.25% to 8.5% saves about ₹2.81 L after ₹38,600 of costs, and breaks even in month 22.
What a balance transfer does
In a balance transfer, a new lender pays off your outstanding home loan and you repay the new lender instead, usually at a lower rate. The tenure normally stays the same, so the EMI falls. The saving builds up month by month, while the costs of switching are paid at the start. The switch is worth it only if the savings comfortably exceed those costs within the time you expect to keep the loan.
A worked example
You owe ₹40 lakh with 15 yrs left at 9.25%. Another lender offers 8.5%, a gap of 0.75 percentage points. It charges a processing fee of 0.5% plus 18% GST, and we assume a further ₹15,000 of legal, valuation and documentation charges.
| Stay at 9.25% | Switch to 8.5% | |
|---|---|---|
| EMI | ₹41,168 | ₹39,390 |
| Interest over remaining tenure | ₹34,10,184 | ₹30,90,125 |
| Switching costs | – | ₹38,600 |
- The ₹38,600 of costs is recovered by month 22. Every month after that is pure saving.
- With these costs, the switch only just pays for itself at a new rate of 9.16%. Any offer above that loses money over the remaining tenure.
Savings by rate gap and years left
The table keeps the balance at ₹40 lakh, the current rate at 9.25% and the same costs, and changes the rate cut and the remaining tenure. Each cell shows the net saving after costs and the month in which you break even.
| Rate cut | 5 yrs left | 10 yrs left | 15 yrs left |
|---|---|---|---|
| 0.25% | −₹9,430 (never) | ₹26,534 (month 72) | ₹68,865 (month 65) |
| 0.50% | ₹19,640 (month 40) | ₹91,287 (month 36) | ₹1,75,554 (month 33) |
| 0.75% | ₹48,608 (month 27) | ₹1,55,658 (month 24) | ₹2,81,460 (month 22) |
| 1.00% | ₹77,475 (month 20) | ₹2,19,645 (month 18) | ₹3,86,574 (month 17) |
Two things stand out. The saving grows sharply with the years left, because a lower rate on a long loan cuts interest on a large balance for longer. And a small gap on a short loan can lose money: a 0.25% cut with 5 yrs left leaves you −₹9,430 after costs.
The costs of switching
The rate cut is what you gain. Before you compare it, list everything you will pay:
- Processing fee of the new lender, usually a percentage of the loan, with 18% GST on top. Some lenders cap it or waive it during offers.
- Legal and valuation charges for the new lender’s checks on the property can apply.
- Stamp duty and registration on the new mortgage can apply in some states.
- Foreclosure charges on the old loan. RBI does not allow these on floating-rate loans taken by individuals for non-business purposes, but a fixed-rate loan may carry one.
When it is not worth it
- the rate gap is small, around a quarter of a percentage point, and the costs are not waived;
- only a few years are left, or most of the interest has already been paid;
- you plan to sell the property or repay the loan in full before the break-even month;
- the new lender’s spread over the benchmark is higher, so the saving may shrink at later rate resets;
- the switch is bundled with a top-up or insurance you do not need, which raises the cost.
The opposite holds too. A gap of half a percentage point or more, with ten years or more left, usually makes a switch clearly worthwhile.
How to transfer your home loan
- Ask your current lender for a rate reduction and note what it offers.
- Get written quotes from new lenders with the rate, the benchmark and spread, and every fee, and compare the net saving.
- Request a foreclosure statement and the list of property documents held by your current lender.
- Apply to the new lender with income proof, the loan statement and property papers, and wait for sanction.
- The new lender pays off the old loan. Collect a closure letter and confirm the old lender returns all original documents to the new lender.
- Check the first statement from the new lender for the rate, EMI and tenure you agreed.
Frequently asked questions
What is the minimum rate difference for a home loan balance transfer?
There is no fixed rule. With typical costs, a gap of half a percentage point or more with ten or more years left usually pays off. Work out the net saving and break-even month for your own balance.
Are there foreclosure charges when I transfer a home loan?
Not on a floating-rate home loan taken by an individual for a non-business purpose. A fixed-rate loan may carry a charge, so check your agreement.
Does a balance transfer affect my credit score?
The new lender will check your credit report, which is recorded as an enquiry. Closing the old loan and opening a new one on time is normally neutral over the long run.
Can I take a top-up loan with a balance transfer?
Many lenders offer one. A top-up adds to your loan and its interest, so compare its rate with other options and take it only if you need the money.
Should I ask my bank to lower the rate instead?
Yes, try that first. Many lenders reduce the rate for existing borrowers, sometimes for a small fee, which avoids fresh legal and valuation costs.
