Biweekly Mortgage Calculator

About this calculator

This calculator compares a standard monthly mortgage schedule against paying half the monthly payment every two weeks instead. Because a year has slightly more than 52 weeks, this pattern quietly results in the equivalent of one extra full monthly payment per year, which shortens the loan term and reduces total interest paid without requiring a large lump sum.

Homeowners use it to see the concrete effect of switching payment frequency, both in terms of years shaved off the mortgage and dollars saved on interest, before committing to a biweekly plan through their lender. It's a common comparison for anyone looking for a low-effort way to pay off a mortgage faster.
