Tools · Refinance Break-Even
Refinance break-even.
Months to recover your closing costs.
Refinancing makes financial sense only when the monthly payment savings recoup the closing costs before you sell or move. This calculator shows the exact break-even and what you save if you stay through the planned period.
US-only. 30-year fixed mortgages are a US product. Other countries use different structures.

What this tool assumes
- Standard mortgage amortization formula: P&I = P × r/(1 - (1 + r)^(-n)), where P is principal, r is the monthly rate, and n is the term in months.
- Closing costs are paid upfront (not rolled into the loan balance). Rolling them in changes the math; this tool does not model that scenario.
- Break-even = closing costs / monthly savings. Whole months, rounded up.
- Net savings if you stay = (monthly savings × months stayed) - closing costs.
- Property tax, insurance, and PMI are not included. Refinancing typically does not affect those except via cash-out reducing equity.
- Tax effects of mortgage interest deduction (limited by SALT and itemization) are not modeled. After the OBBBA-permanent standard deduction ($16,100 single / $32,200 MFJ in 2026), most filers do not itemize and the deduction does not change effective rate.
