Bi-Weekly vs Monthly

The Bi-Weekly vs Monthly Calculator compares the total cost and timeline of making 26 half-payments per year (bi-weekly) versus 12 full payments per year (monthly). Bi-weekly payments effectively result in one extra full payment per year. This seemingly small change can shave years off a mortgage and save thousands in interest without requiring a larger monthly commitment. The calculator shows the exact years saved, interest saved, and effective extra annual payment. Many borrowers overlook this strategy because it feels insignificant, but over a 25-30 year mortgage the compounding effect of that extra annual payment is substantial. This tool quantifies the benefit so you can decide if setting up bi-weekly payments is worth the effort.
