This JavaScript calculator will help you to decide whether
or not you should refinance your current mortgage at a lower interest rate. Not only will
this calculator calculate the monthly payment and net interest savings, but it will also
calculate how many months it will take to break even on the closing costs.
Note: When entering numbers into the data fields only use numbers and applicable
decimal points. Entering commas, dollar signs, or any other nonnumeric characters will
cause an error. Also please note that your webbrowser must have
the JavaScript option turned on.
