Refinance Calculator
Compare the current loan with a new rate, new term, closing costs, break-even timing, and the risk of restarting the mortgage clock.
Formula
How refinance break-even is estimated
The calculator estimates current and new principal-and-interest payments, then divides closing costs by monthly payment savings. It also compares remaining interest under the current loan with the new loan term.
FAQ

Recommended Tools to Help You Take Action
These neutral examples fit the mortgage action suggested by the calculator. Compare APR, lender fees, closing costs, PMI assumptions, and break-even timing before choosing a path.
If the payment looks affordable, compare lender estimates from options such as Rocket Mortgage, LendingTree, or SoFi Mortgage.
If the result points to payment stress or future savings, compare refinance options through platforms such as Credible or LendingTree refinance.
If PMI or income burden is the issue, use affordability and PMI tools to test down payment changes, LTV, and monthly payment risk before contacting a lender.
