How this calculator works

A biweekly schedule pays half the normal monthly amount every two weeks. That produces 26 half-payments—or 13 monthly equivalents—per year instead of 12.

Frequently asked questions

Why can biweekly payments save interest?

Twenty-six half-payments equal 13 full monthly payments per year, so more principal is paid over the year.

Will every lender process payments this way?

No. Some lenders hold partial payments until a full payment is available or charge program fees. Confirm the posting policy first.

Is this the same as paying twice a month?

No. Twice-monthly payments produce 24 half-payments, while true biweekly payments produce 26.
