Biweekly Mortgage Payment Calculator
True biweekly mortgages collect half the monthly payment every two weeks — 26 half-payments a year, which equals 13 full monthly payments. That extra payment per year pays the loan down faster than 12 monthly payments at the same rate.
This calculator uses 26 periods per year with the standard half-monthly payment amount, not monthly divided by two on a monthly schedule. The summary compares interest saved versus paying monthly.
Controls below let you switch back to monthly for side-by-side planning. Not financial advice.
