How Biweekly Mortgage Payments Work
With a standard monthly mortgage, you make 12 payments per year. Switch to biweekly and you pay every two weeks, which adds up to 26 half-payments — or 13 full monthly payments annually. That one extra payment per year goes entirely toward principal, cutting your interest and loan term significantly.
On a $350,000 loan at 6.75% for 30 years, biweekly payments typically save over $60,000 in interest and pay off the loan about 4-5 years early.
Biweekly vs Monthly: Key Differences
Payment Frequency
Monthly = 12 payments/year. Biweekly = 26 payments/year. The extra payment per year is what drives all the savings.

Interest Savings
Each biweekly payment reduces your principal faster, so less interest accrues. The compounding effect grows substantially over a 30-year term.

Quick Tip: The DIY Biweekly Method
If your lender does not offer biweekly payments, divide your monthly payment by 12 and add that amount to every monthly payment labeled apply to principal. On a $350,000 loan at 6.75%, that is about $190 extra per month.
