Calculation details

Formula and methodology

See the exact math used to produce the result.

New payment uses the fixed-rate amortization formula. Monthly savings = current comparable principal-and-interest payment minus new payment. Break-even months = closing costs divided by positive monthly savings.

Before acting

Assumptions to check

Review the real-world details that can change the estimate.

Compare principal and interest on both sides. The result does not automatically include points, financed fees, escrow, taxes, insurance, PMI, prepayment effects, a reset loan term, or how long the home will be kept.

FAQs

Mortgage Refinance Calculator questions

What does refinance break-even mean?

It is the modeled number of months of payment savings needed to recover the entered closing costs. It does not measure every cost or benefit of the new loan.

Should my current payment include taxes and insurance?

Use the comparable principal-and-interest portion unless the new-payment side includes the same escrow items. Mixing scopes distorts monthly savings.

Does a lower payment always mean the refinance saves money?

No. A longer term, larger balance, fees, points, or staying past a different time horizon can increase total cost despite a lower payment.
