How it is calculated
The calculation compares two totals: how much would still be paid on the current loan (annuity payment over the remaining term × number of months) and how much would be paid on a new loan for the same balance (new annuity payment × new term plus the one-off refinancing fee). The difference is the savings, or the extra cost.
Refinancing isn't always worth it even at a lower rate: if the new term is noticeably longer than the old one, total interest can rise despite the lower rate — the calculator accounts for both effects at once, not just a rate comparison.
The refinancing fee eats into the benefit right away — if it's large relative to the interest savings and little time is left on the current loan, refinancing may not pay off. The calculation doesn't include a possible loss of a tax deduction or insurance payout when re-registering — check that separately.
