Refinance Break-Even Calculator

Refinancing is not automatically worth it when rates fall: closing costs must be recovered first. Payment savings times months must exceed the cost; if you sell before the break-even month, you may not recover it.

Where people go wrong

  • Comparing rates only, not payments and closing costs.
  • Treating break-even months as the loan term.
  • Ignoring that amortization restarts.

FAQ

Is a 30-month break-even good?

It depends on whether you will sell or refinance within 30 months; staying longer is usually safer.

What is in closing costs?

Appraisal, title, recording, lender fees and more; use the total on the Loan Estimate.
