Model a new loan

Refinance Calculator

Refinancing replaces your current loan with a new one, usually to lower the rate, change the term, or tap equity. Enter the balance you would refinance and today's rate to see the new payment and total interest, then weigh it against your current loan and closing costs.

The real question

It is not the rate, it is the break-even

A lower rate looks great, but refinancing costs money up front, typically 2% to 5% of the loan in closing costs. The number that matters is the break-even point: your monthly saving divided into those costs tells you how many months until the refinance pays for itself. If you plan to move before then, it rarely makes sense.

To use this tool for a refinance, enter your remaining balance as the loan amount (set the home price to the balance and down payment to zero), pick the term you want, and use today's rate. Compare the resulting payment and total interest against your current loan.

Watch the term

A lower payment can still cost more

Refinancing a 30-year loan you are 6 years into back to a fresh 30-year term lowers the payment, but it also restarts the clock and can raise the total interest you pay. If the goal is to save money overall, compare total interest, not just the monthly figure, and consider matching the remaining term.

Questions & answers

Frequently asked

How do I model my refinance here?
Set the home price to your remaining balance, the down payment to zero, choose your new term, and enter today's rate. The result is your new principal and interest, plus tax and insurance if you add them.
What is a break-even point?
The number of months it takes for your monthly savings to cover the refinance's closing costs. Divide total closing costs by your monthly saving. Stay in the home past that point and the refinance pays off.
Should I refinance to a shorter term?
If you can afford the higher payment, a shorter term usually carries a lower rate and dramatically less total interest. Compare the total-interest figures for a 15-year and a 30-year to decide.
Does a lower rate always save money?
Not necessarily. Closing costs and a reset term can erase the savings. Always compare total interest and factor in how long you plan to stay.
