Mortgage Refinance Break-Even: How to Compare Costs and Savings
A lower refinance payment can look attractive, but closing costs and a changed loan term affect the decision. Estimate a payment-based break-even point and review the full loan costs.

This guide explains a comparison framework and links to an interactive calculator. Results depend on the values and assumptions entered; they are not personalized financial advice.
Estimate payment savings and upfront costs
A simple payment break-even estimate divides upfront refinance costs by the monthly principal-and-interest savings, if the proposed payment is lower. Use actual lender documents when possible; an estimate based on a guessed fee or rate can mislead.
Check how long you expect to keep the loan
Compare the break-even time with your likely time in the home or loan. If you sell or refinance again before reaching the break-even point, you may not recover costs through payment savings.
Account for the new term
A refinance can restart the repayment clock. Extending the term may reduce the required monthly payment while adding months of interest. Compare total costs over the period that matters to you and consider the remaining balances, not only the payment.
Review the Loan Estimate
Compare interest rate, APR, points, lender credits, total loan costs, cash to close, and the full monthly payment. “No-cost” offers may cover costs through a higher rate or by adding costs to the loan, so inspect the terms carefully.
