Looking for a mortgage calculator

Does anyone know of a mortgage calculator that will allow you to add extra principle and make payments every 2 weeks? Bankrate allows you to do either, but they do not stack. I have determined that making the extra principle payment each month will cut about 10 years off the loan, and paying every two weeks will cut 4 years off, but I think if you make extra principle payment every two weeks it will take more than 14 years off the loan.

Anyone know of a website?

I approximate it by summing up the total extra principle payments into one yearly payment.
