Start with the current principal outstanding and remaining months. Compare the old and new loan over the same target payoff date. A new lender can make the EMI look lower by restarting a long tenure, even when lifetime interest increases.
Build the break-even calculation
| Switching cost | Include |
|---|---|
| New processing/admin fees | All applicable charges/taxes |
| Legal/valuation/document costs | Actual quotes |
| Old lender closure-related costs | Only those actually applicable |
| Operational cost | Document movement, temporary cash gap |
Estimate monthly interest saving under a realistic rate path. Break-even months = total switching cost ÷ monthly saving. If you expect to sell, prepay or refinance again before break-even, the transfer is weak.
Compare benchmark + spread + reset
Do not compare only today’s headline rates. Record each loan’s benchmark, spread, reset frequency and borrower options. The RBI’s floating-rate reset FAQ describes communication and options when rate resets affect EMI/tenure.
Keep the remaining term constant in your calculator
Run three cases: current loan unchanged, transfer with same remaining term, and transfer with lender-proposed term. This exposes how much of the EMI reduction comes from rate savings versus simply borrowing for longer.
Plan document and security movement
Confirm the old lender’s foreclosure statement, new lender disbursal conditions, original-property-document handover, charge/lien release and creation, and what happens if there is a timing mismatch.
Do a final rate-shock test
Model the new loan at +1 percentage point as well as today’s rate. A transfer that only works at the introductory/current rate may be too fragile.
Decision rule: transfer when the same-term total cost is lower after every switching cost, break-even is comfortably inside your expected holding period, and the new reset structure remains affordable under a rate shock.
