Calculator available to show mortgage term reduction ?

[Vaughan Moody]

Can anyone point me towards an online calculator that will show how much sooner we would pay off our mortgage if we divided our monthly repayment amount by two and paid that amount (half of a monthly amount) every two weeks, instead of paying the monthly amount once a month?

Thanks in advance!
