The three variables that decide it
Rate gap alone tells you very little. It has to be read against the other two.
- Rate gap: the difference between your current rate and what you can get today
- Remaining tenure: interest saving accrues over time, so a short remaining term kills the case
- Outstanding balance: a 2 point gap on Rs 2 lakh is worth a fraction of the same gap on Rs 20 lakh
- Against those three, weigh a processing fee of typically 1 to 2 percent of the new loan
