Refinance Calculator

Estimate whether refinancing pays off. Compare current and proposed loan terms to estimate break-even month and long-term savings after refinance costs.

How the estimate works

Current and proposed payments use standard amortization. Break-even months divide closing costs by monthly payment savings.
Change one assumption at a time to compare scenarios.
Use current balances, rates, costs, and timelines whenever possible.

Important limitation

A longer replacement term can lower the payment while increasing lifetime interest. Results are estimates only and are not financial, lending, legal, tax, or investment advice.
