## How this is calculated

Compares the remaining EMI and total interest on an outstanding home loan at the current lender against a new lender at a different rate, over the same remaining tenure, then nets the interest saved against the one-time cost of switching to find whether refinancing pays off.

**Formula:** `EMI_old = computeEMI(P, oldRate, n); EMI_new = computeEMI(P, newRate, n); netSavings = (EMI_old - EMI_new) x n - switchingCost; breakEvenMonths = switchingCost / (EMI_old - EMI_new)`

**Variables:**

- `P`: Outstanding loan principal, in INR
- `oldRate`: Current lender annual interest rate, as a percentage
- `newRate`: New lender annual interest rate, as a percentage
- `n`: Remaining loan tenure, in months
- `switchingCost`: Processing fee plus other transfer costs plus any prepayment penalty, in INR

Reference: Matches the EMI-difference-minus-switching-cost methodology used by BankBazaar's Home Loan Balance Transfer Calculator.

## Assumptions

- Assumes the new lender finances the exact outstanding principal over the same remaining tenure as the current loan; a longer or shorter new tenure changes the comparison.
- Floating-rate home loans carry no prepayment penalty under RBI rules; the calculator zeroes this cost automatically when the floating-rate option is selected.

## Frequently asked questions

### Is a 1% rate cut on a 40 lakh loan worth switching for?

Usually yes, over a 15-year remaining tenure a 1% cut saves lakhs in interest, comfortably covering a typical 0.5% processing fee and other transfer costs within the first year or two.
