Refinance break-even

Compare monthly payment savings and changes in your remaining balance. A longer term can slow principal repayment.

Two ways to measure break-even

Payment break-even divides cash closing costs by monthly payment savings. True-cost break-even also accounts for the difference in remaining balances. A smaller monthly payment can still cost more over time if you restart a longer term.

Enter the costs you actually pay

Include lender and third-party refinance costs. Select financed costs if they increase the new balance. Zero cash costs with positive payment savings show immediate payment break-even. Taxes, insurance, penalties and changing rates are outside this model.
