Use the calculator near the top of the page, review the summary table, then change one input at a time to compare realistic scenarios before making a final decision.

What is the Refinance Calculator?

A refinance calculator compares a current loan with a new loan to estimate savings, costs, and the time needed to recover refinance fees.

It is designed to turn common planning inputs into a clear estimate, so users can understand the numbers before comparing options, speaking with a professional, or moving forward.

What mortgage refinancing means

Mortgage refinancing means replacing an existing home loan with a new loan. Borrowers often refinance to seek a lower interest rate, change the loan term, switch loan type, or access equity.

This refinance calculator helps estimate payment changes, possible savings, closing cost impact, and break even time before a borrower applies.

How to use the Refinance Calculator

Start with realistic numbers. If you do not know an exact value yet, use a careful estimate and update it later when you have a quote, statement, pay stub, tax document, or lender figure.

  1. Enter current loan balance, rate, payment, and remaining term.
  2. Add the new rate, new term, and closing costs.
  3. Review monthly savings, break even months, and total cost comparison.
  4. Test several new rate or cost scenarios.

Example

For example, a user can open the Refinance Calculator, enter a realistic loan balance and rate, then compare the result with another payment scenario. This makes it easier to see whether the option fits the monthly budget before moving forward.

Refinance break even formula

Break even months = closing costs / monthly savings
  • Monthly savings = old payment - new payment
  • Closing costs can include lender and legal fees
  • Cash out refinance may change the loan balance

Compare the break even point with how long you expect to keep the mortgage.
