How this mortgage refinance calculator works
Refinancing replaces your current mortgage with a new loan, ideally at a lower rate or shorter term. This calculator compares your current monthly payment against the new payment and computes the break-even point — the number of months it takes for the monthly savings to recoup the closing costs.
- Calculate the new monthly payment using the refinanced loan amount, new rate and new term.
- Monthly savings = current payment − new payment (principal & interest only).
- Break-even months = total refinance closing costs ÷ monthly savings.
- Net savings over the remaining planned ownership period = (months remaining − break-even months) × monthly savings, minus any term extension effect.
Refinancing extends your loan term unless you select a shorter one, and closing costs increase total costs in the short term. Verify today's rates with your lender.
