Note: This calculator will show you how much you will save if you make 1/2 of your mortgage payment every two weeks instead of making a full mortgage payment once a month. In effect, you will be making one extra mortgage payment per year -- without hardly noticing the additional cash outflow. But, as you're about to discover, you will certainly notice the "increased" cash flow that will occur when you pay your mortgage off way ahead of schedule!

When entering numbers into the data fields only use numbers and applicable decimal points. Entering commas, dollar signs, or any other non-numeric characters will cause an error. Also please note that this calculator has been tested to work with Internet Explorer 5.5 and Netscape Navigator 4.6 web browsers. However, both must have the JavaScript option turned on.
