“Transfer your home loan. Save up to ₹7 lakh.” A client in Ahmedabad forwarded me that SMS last year and asked the obvious question: is this real or is this a trap? The honest answer is that it's both, depending on two numbers the ad never mentions — how much you still owe, and how long you have left. For him it was real. I've also talked two other clients out of the same move because for them it would have been a net loss dressed up as a saving.
Let me work his case first, with actual figures, and then show you the version where the exact same ad quietly costs you money.
The case where the ad was right
His loan: ₹58L outstanding, 16 years remaining, at 9.4% with a bank that had been slow to pass on repo rate cuts. A competing bank offered 8.5% on transfer. His EMI at 9.4% was about ₹58,500. At 8.5% on the same 16-year tenure, it drops to roughly ₹55,350. That's a saving of about ₹3,150 a month.
Now the part the ad skips: switching isn't free. The new bank charged a processing fee of ₹11,800 including GST. Then there's MODT — the mortgage deed stamp duty and registration on the new bank's charge over the property — plus legal opinion and valuation charges, which came to about ₹36,000 in Gujarat. Call it ₹48,000 all-in. Some banks also quietly add login fees or insist on a bundled insurance policy; he was asked to buy one and declined, which you're allowed to do.
So: ₹48,000 of cost, ₹3,150 of monthly saving. He recovers his switching cost in about 15 months, and every month after that is pure gain. Over the remaining 16 years the gross saving works out to just over ₹6L, or about ₹5.5L after costs. The ad said “save lakhs” and, for once, the ad was right.
The break-even formula
Everything above compresses into one line, and I'd rather you have the formula than my anecdote:
Break-even months = total switching cost ÷ monthly EMI saving.
Total switching cost means everything — processing fee with GST, MODT/stamp duty, legal and valuation charges, and any foreclosure-adjacent charges your current bank sneaks in (on floating-rate home loans to individuals, RBI rules say there should be no foreclosure penalty, but check the statement anyway). Then hold that break-even number against your remaining tenure. My working rule: the transfer has to break even inside a quarter of the time you have left. 15 months against 192 remaining months clears that easily. 40 months against 60 remaining months does not, even though it technically “breaks even.”
The case where the same ad loses you money
Different client, same year, same SMS. Her loan: ₹18L outstanding, 4 years left, 9.4%. The offer was 8.9% — a smaller cut, because the best transfer rates go to large, long loans. Her EMI drops from about ₹45,100 to ₹44,700. That's ₹400 a month. Against roughly ₹40,000 of switching costs, break-even is over 90 months — on a loan that finishes in 48. She would have paid ₹40,000 to save about ₹19,000. The ad doesn't lie, exactly. It just assumes you're the ₹58L borrower and not the ₹18L one.
The pattern is simple once you see it: rate cuts save you money on the interest you haven't paid yet, and most of a loan's interest sits in its early years. Big balance, long tenure, meaningful rate gap — transfer. Small balance or short tenure — the fixed costs eat the saving.
Try the free option first
One more thing I make every client do before filling a single transfer form: call your existing bank and ask for a rate conversion. Most lenders will reset your spread to something close to their current new-customer rate for a flat conversion fee — typically ₹2,950 to ₹5,900. My ₹58L client asked; his bank offered 8.85% for ₹5,900. He still transferred, because 8.5% beat it even after full costs. But I've had three other clients where the conversion alone captured most of the saving for a twentieth of the cost and zero paperwork. If you want us to run the break-even on your actual sanction letter, that's exactly the kind of thing our loan advisory work covers.
