Loan against property balance transfer calculator (India)

What a loan against property transfer involves

A loan against property balance transfer moves a mortgage-backed loan to another lender for a lower rate. Mechanically it looks like a home loan transfer: the new lender sanctions against a fresh valuation, pays off the existing loan, and takes the title deeds. Bajaj Housing Finance advertises rates from 9.85% per year and Tata Capital from around 9% (as at 2026-09-03), and both, with L&T Finance and Jio Credit, publish transfer calculators that compare EMIs. The difference from a home loan is not the interest arithmetic. It is that the cost of reaching the lower rate is much larger, and large enough to change the answer.

The switching costs, as at 2026-09-03

GST at 18% applies to the fee components. Interest on a loan is GST-exempt in India, and stamp duty is a state levy rather than a service, so neither carries GST. On a Rs 30 lakh balance those lines add to roughly Rs 70,000 to Rs 80,000, against perhaps Rs 20,000 on a home loan of the same size where foreclosure is nil and the processing fee is capped.

The fresh valuation can cap what moves

A loan against property is sanctioned at a loan-to-value of roughly 50% to 70% of market value, well below the ratio allowed on a home loan, because the lender is underwriting a general-purpose loan rather than a purchase. The new lender values the property on its own panel valuer’s view, which can differ from the old lender’s number from several years ago.

The practical consequence is a ceiling on the transfer. If Rs 30 lakh is outstanding and the fresh valuation supports only Rs 26 lakh, then Rs 26 lakh moves and the remaining Rs 4 lakh has to be settled from other funds before the title deeds are released. Under those inputs the saving applies to the smaller balance while the switching costs apply in full.

Business-purpose loans and the micro and small enterprise branch of the rules

A large share of these loans are taken for business working capital, and the purpose recorded in the sanction letter changes which rule applies. Under the RBI (Pre-payment Charges on Loans) Directions, 2025, applying to loans sanctioned or renewed on or after 1 January 2026:

• A floating-rate loan to an individual for a non-business purpose carries no pre-payment charge, at any amount.
• A floating-rate business loan to an individual or a micro or small enterprise carries no charge at commercial banks and upper-layer non-banking finance companies. At middle-layer non-banking finance companies and small co-operative banks the free band is limited to a sanctioned amount of up to Rs 50 lakh, tested on the sanctioned amount rather than the outstanding balance and per lender rather than in aggregate (secondary source).
• Fixed-rate loans are not covered at all, whatever the purpose or the borrower.

Whether a borrower is a micro or small enterprise turns on the MSMED classification thresholds, and whether a lender sits in the upper or middle layer is set by RBI’s scale-based regulation. Both are questions for the existing lender in writing rather than assumptions to build into a calculation. Loans sanctioned before 1 January 2026 keep the terms they were sold on.

A worked example

Take the calculator’s default figures: Rs 30,00,000 outstanding, 120 months left, 11.5% moving to 9.85%, a processing fee of 1% plus GST, no foreclosure charge because the loan is floating rate to an individual for a non-business purpose, and Rs 40,000 covering stamp duty on the fresh mortgage, valuation, legal and documentation. The EMI follows the standard annuity formula, EMI = P × r(1+r)ⁿ / ((1+r)ⁿ − 1).

• Old EMI at 11.5% for 120 months: about Rs 42,179. Total interest still to pay: about Rs 20,61,435.
• New EMI at 9.85% over the same 120 months: about Rs 39,396. Total interest: about Rs 17,27,573.
• Monthly relief: about Rs 2,782. Interest saved before costs: about Rs 3,33,862.
• Cost of switching: Rs 30,000 processing plus Rs 5,400 GST, plus Rs 40,000 of mortgage, valuation and legal costs. Total Rs 75,400.
• Net saving over the full tenure: about Rs 2,58,462, with the saving overtaking the cost in month 19 of 120.

Holding the EMI at the old figure instead of taking the relief clears the loan in about 108 months and lifts the net saving to roughly Rs 4,62,849. Note also how thin the margin is: the offer would only have to weaken to about 11.13%, a cut of roughly 0.37 percentage points instead of 1.65, for the whole exercise to net to zero. Two thirds of the apparent rate advantage is consumed by the cost of re-mortgaging.

Why the break-even month is the number to watch

On a home loan transfer with nil foreclosure and a capped processing fee, break-even usually lands inside the first year and the decision turns on the size of the saving. Here the costs are a percentage of a large loan, so break-even is commonly a year and a half to three years out, and the answer stops being about the rate gap and becomes about whether the loan will still be running when the saving arrives. Selling the property, prepaying from a business inflow, or transferring again inside that window means paying the full switching cost and collecting only part of the benefit. Under the example above, an exit in month 12 leaves the borrower worse off than doing nothing, despite a 1.65 percentage point rate cut. A third comparison no lender calculator offers is applying the same Rs 75,400 as a part-prepayment on the existing loan, which costs nothing to arrange where prepayment is free.

Top-up on the transfer

Transfers are often marketed with a top-up, since the property is being revalued anyway and any headroom below the loan-to-value ceiling can be lent, at a rate far below a personal loan or a credit card. Two cautions belong in the arithmetic. Re-amortising a top-up over the full remaining tenure can generate more total interest than the shorter, dearer borrowing it replaces, and the security is the property rather than a signature. The calculator shows the extra EMI and extra interest on their own line, so the transfer verdict is not flattered by borrowing added alongside it.

Where the arithmetic tends to say no

• A short remaining tenure. With three years or less to run, percentage-based mortgage costs rarely recover from the interest still at stake.
• A rate gap under about one percentage point. The costs here are large enough that a small cut nets to nothing, as the break-even rate above shows.
• A fixed-rate or business-purpose loan with a foreclosure charge. Adding 2% to 5% of the outstanding balance can double the costs above.
• A valuation that has fallen. A shortfall against the fresh loan-to-value has to be found in cash before the switch can complete.
• A planned exit. Where the property is likely to be sold or the loan cleared inside the break-even month, the costs are paid and the saving is not collected.

How to use the calculator above

Enter the outstanding principal from the latest statement, the rate charged now, the months left, and the rate quoted in writing rather than the advertised starting rate. Set the foreclosure percentage from the sanction letter after checking the rate type, the purpose and the sanction date against the 2026 rules. Add stamp duty, valuation, legal, CERSAI and documentation together into the other costs box, since those are the lines that decide this product. Then read the break-even month first and the net saving second, and compare the same-EMI path against the same-tenure path.
