Biweekly mortgage payments equal 26 half-monthly payments per year = 13 monthly equivalents. On a 30-year mortgage, this typically pays off the loan 5-7 years early and saves $30K-$80K in interest. The savings come from one extra payment per year + faster principal reduction.
How Biweekly Works
Standard: 12 monthly payments per year. Biweekly: 26 half-monthly payments = 13 full monthlies per year. The extra 1 payment goes straight to principal. Faster principal reduction → less interest charged on remaining balance.
Setup Methods
(1) Self-managed: pay half on 1st, half on 15th. (2) Bank biweekly program (sometimes $9.95/month fee — avoid this). (3) Automatic ACH biweekly. (4) Extra $X/month to principal (equivalent math, no biweekly logistics).
Caveats
Some lenders apply biweekly to monthly cycle (no benefit). Others have prepayment penalties (rare modern). DIY is cleanest: pay half monthly OR extra 1/12 per month — same effect, no fee. Verify lender applies extra to principal.
