FAQ

How is the refinance break-even calculated?

Break-even = closing cost ÷ monthly savings. If you save $200/month and pay $4,000 in closing costs, you break even in 20 months.

Does extending the term save money?

Extending the term lowers monthly payments but increases total interest paid. The calculator shows lifetime savings net of closing costs so you can see the full picture.

What closing costs should I include?

Typical closing costs are 2–5% of the loan and include origination fees, appraisal, title insurance, and prepaid items. Get a Loan Estimate from your lender for exact figures.
