The Bi-Weekly Mortgage: 13 Payments Per Year. A bi-weekly mortgage payment program is meant to short-circuit your loan's amortization schedule. Instead of taking 12 payments per year, the bi-weekly payment plan asks for one payment every two weeks, which adds up to 13 payments per year.Except that you can't make 13 payments per year on your mortgage -- that's not how a mortgage works.ith a mortgage, you pay a certain amount of interest on an annual basis and that amount is covered in your first twelve payments. The 13th payment has to go somewhere, though, so it gets applied to your principal balance; the amount that you still owe to the bank. And, this is how a bi-weekly payment plan works.
