Mortgage Refinance Break-Even

$6,000 in closing costs. $200 less P&I each month. Simple cash break-even: 6,000 ÷ 200 = 30 months. Sell or refinance again before that, and the payment cut alone may not have paid for the fees. That screen is useful — and incomplete. Use the mortgage refinance calculator to see monthly savings, months to recover costs, and whether total interest still rises.

What that 30-month figure really is

Cash break-even is closing costs divided by the monthly payment reduction, rounded up to whole months. It ignores the time value of money and tax effects. It is a planning screen, not a full present-value model.

If the new payment is not lower, there is no payment-based break-even. People still refinance to shorten the term, drop PMI, or leave an adjustable rate — those goals need a different comparison than “months until the payment cut covers the fees.”

The trap: restarting a 30-year clock

You have already paid several years on the current loan. Refinance into a fresh 30-year term and you can increase lifetime interest even when the rate is lower. The calculator flags that case. A lower payment bought with more years of debt is a cash-flow choice — not proof the refinance “saves money” overall. Compare remaining interest on the current loan with interest on the new loan, including costs rolled into the balance.

Costs hide in more than one place

Closing costs often include origination, appraisal, title, recording, and prepaid interest. Ranges like about 2%–5% of the loan amount are educational, not a quote. A “no-closing-cost” refinance usually means costs sit in the rate or the balance. Rate quotes expire; do not treat an example rate in a calculator as a market forecast.

Planning extra principal after you refinance? Model it separately with the extra payment calculator. Shortening the term without refinancing? Compare 15-year and 30-year payment differences.
