FAQ

Frequently asked questions

How the calculation works and where its limits are.

How do I calculate the break-even point on a mortgage refinance?

Break-even point in months equals Total Refinance Closing Costs divided by Monthly Payment Savings (Closing Costs / Monthly Savings). For example, if refinancing costs $4,500 and saves $150 per month, your break-even period is 30 months (2.5 years).

What happens if I sell or move before reaching the break-even point?

If you sell the home or refinance again before reaching break-even, you will lose money because cumulative monthly savings will not have recovered the upfront closing fees paid to execute the new mortgage.

How does resetting the loan term affect total lifetime interest paid?

Refinancing a loan with 22 years remaining into a fresh 30-year mortgage might lower your monthly payment, but the 8 extra years of interest charges could increase your total lifetime interest expense significantly.

Is this refinance calculation a formal mortgage quote?

No. This calculator provides deterministic planning estimates based on your entered interest rates and closing fees. Actual refinance approval requires formal credit check, property appraisal, and a licensed lender Loan Estimate.

What should I do after calculating my refinance break-even period?

Request Loan Estimates from at least three competing mortgage lenders on the same day, compare Section A origination charges, and verify that your planned duration in the home exceeds the break-even window.
