About the Refinance Calculator
Refinancing replaces your mortgage with a new one, usually to get a lower rate. It costs money — typically 2–5% of the loan in the US, or arrangement and legal fees elsewhere — so it only pays off after the break-even point.
Break-even = costs ÷ monthly saving. Watch the term: restarting a 30-year loan lowers the payment but can increase total interest.
