Twenty-six half payments make thirteen whole ones, so nearly all of the saving is one extra payment a year. The last figure shows the same extra money paid monthly, without the two-week schedule. This assumes each half is applied the day it arrives. Some servicers hold the first half until the second comes, and then only the extra payment counts. Any fee for setting it up is not included.
