Home-loan balance transfer after the repo hike: the break-even sum and the fees people miss

Rules and rates as of 12 October 2026.

On 7 October the Reserve Bank of India raised the repo rate to 5.50%. If your home loan is linked to the repo rate, your rate rises at the next reset, and so does everyone else's. What does not change with a hike is the spread: the fixed margin your lender adds on top of repo. Two borrowers with identical loans can sit 0.5 to 1 percentage point apart purely because of the spread each was given at sanction. A balance transfer, moving the outstanding loan to a lender with a lower spread, is how people close that gap. Whether it is worth doing comes down to one division.

Why the spread is the number to compare

RBI's September 2019 circular required banks to link new floating-rate retail loans, including home loans, to an external benchmark such as the repo rate or a Treasury Bill yield, from 1 October 2019. The rate must be reset at least once every three months. The spread is set by the bank, and the circular restricts how it can move: the credit-risk part may change only if your credit assessment changes substantially, as agreed in the loan contract, and other components such as operating cost may be altered once every three years.

So when repo moves, a repo-linked loan with a 3.25% spread and one with a 2.60% spread both move by the same amount. The 0.65-point gap stays. A rate hike makes the absolute rate higher, which makes each spread point cost more in rupees on a large balance. That is the case for checking your spread now rather than your headline rate.

Two cautions. The 2019 circular was addressed to banks; loans from housing finance companies may be priced off the lender's own reference rate, so compare the actual rate offered and how it resets, not just the word "repo". And your existing lender may agree to reduce your spread for a fee without a transfer; that option belongs in the same calculation.

The break-even formula

A balance transfer has costs up front and savings spread over time. Two numbers tell you whether it works:

• Break-even months = total switching costs ÷ monthly EMI saving.
• Net saving = (monthly EMI saving × months remaining) − switching costs.

EMI is computed as P·r·(1+r)ⁿ ÷ ((1+r)ⁿ − 1), where P is the outstanding principal, r is the annual rate ÷ 12, and n is the remaining months. If you plan to sell the flat or prepay the loan in full before the break-even month, the transfer loses money even if the new rate is lower.

A worked example

An illustrative borrower has ₹50,00,000 outstanding with 15 years (180 months) left. The loan is repo-linked at a spread of 3.25%, so after the hike the rate is 5.50% + 3.25% = 8.75%. Another lender offers repo + 2.60% = 8.10%. Both rates are assumptions for the example, not quotes.

Current EMI at 8.75%: r = 0.0875 ÷ 12 = 0.0072917. EMI = ₹49,972.

New EMI at 8.10%: r = 0.081 ÷ 12 = 0.00675. EMI = ₹48,072.

Monthly saving: ₹1,901 (₹1,900.73 using the unrounded EMIs of ₹49,972.43 and ₹48,071.70).

Now the costs, all illustrative assumptions since they vary by lender and state:

• Processing fee of 0.5% on ₹50 lakh plus GST: ₹29,500
• Legal and valuation charges at the new lender: ₹7,500
• Stamp duty on the new mortgage (memorandum of deposit of title deeds), which is set by each state: ₹10,000
• Document retrieval, registration filings and incidentals: ₹5,000

Total switching cost: ₹52,000. Foreclosure charge on the old loan: nil (see below).

Break-even: ₹52,000 ÷ ₹1,901 = 27.4 months, a little over two years.

Net saving if the loan runs its full 15 years: ₹1,901 × 180 = ₹3,42,132 in lower EMIs, minus ₹52,000 = about ₹2,90,000. Total interest over the remaining term falls from ₹39,95,038 to ₹36,52,906.

The saving is not discounted for the time value of money, and it assumes the spread on both loans stays put. Rupee figures are rounded; the arithmetic was run in Python.

How sensitive the answer is to the spread gap

Same ₹50 lakh, 180 months, current rate 8.75% and ₹52,000 in switching costs. Only the new lender's spread changes:

New spread (rate)	New EMI	Monthly saving	Break-even	Net saving over 15 years
3.00% (8.50%)	₹49,237	₹735	70.7 months	₹80,382
2.75% (8.25%)	₹48,507	₹1,465	35.5 months	₹2,11,775
2.60% (8.10%)	₹48,072	₹1,901	27.4 months	₹2,90,132
2.25% (7.75%)	₹47,064	₹2,909	17.9 months	₹4,71,556

A quarter-point gap takes nearly six years to recover the costs. A full-point gap pays back in about a year and a half. The shorter your remaining tenure or the smaller your balance, the further right on this table you need to be.

The fees people forget

Foreclosure on the old loan

RBI's Pre-payment Charges on Loans Directions, 2025 bar every regulated lender from levying pre-payment charges on floating-rate loans to individuals for non-business purposes, with or without co-borrowers, regardless of where the money to repay comes from and with no minimum lock-in. They apply to loans sanctioned or renewed on or after 1 January 2026. For an older loan, check the sanction letter and ask the lender in writing; a fixed-rate or dual-rate loan may be treated differently depending on whether it is on a floating rate when prepaid.

Stamp duty on the new mortgage

The new lender will usually create a fresh mortgage by deposit of title deeds, and the state charges stamp duty on it. Rates and caps differ by state, so the ₹10,000 above is a placeholder: ask the new lender what it will collect for your property's state.

Charges recovered "at actuals"

Legal opinion, valuation, property insurance and similar third-party costs are often passed on. Under RBI's April 2024 Key Facts Statement circular, applicable to retail and MSME term loans sanctioned on or after 1 October 2024, the KFS must show an annual percentage rate that includes all charges, list third-party charges separately, and a lender cannot later levy a fee not mentioned in the KFS without your explicit consent. Ask for the KFS before signing and add up every line.

Top-ups and bundled insurance

Transfer offers often come with a top-up loan or a loan-protection policy. Either changes the comparison. Keep the transfer amount equal to your outstanding balance when you run the break-even, and price any add-on separately.

The tenure trap

Some lenders show a lower EMI by stretching the remaining tenure. That raises total interest. Run the comparison at the same remaining months; if you want the saving to shorten the loan instead, keep the old EMI and ask the new lender for the resulting tenure.

What else to weigh

RBI's August 2023 circular on resetting floating rates requires lenders to communicate any increase in EMI or tenure immediately, to disclose all charges for switching from floating to fixed in the sanction letter, and to allow prepayment in part or full at any point. If your current lender lengthened your tenure after earlier hikes without you noticing, your "months remaining" may be larger than you think. Check the latest statement before you plug numbers in.
