Get the current outstanding and remaining schedule. Confirm principal, rate and tenure.
Obtain the new effective rate formula. Record benchmark, spread and reset rules, not only the introductory rate.
Calculate payments on equal remaining tenure. This isolates rate savings.
Add every switching cost. Include legal, valuation, documentation and insurance changes.
Calculate break-even and stay period. Transfer only if you expect to keep the loan long enough to recover costs with margin.
Decision rule: the transfer should reduce total future cost under a realistic rate scenario—not merely reduce the next EMI by stretching repayment longer.
