Do Biweekly Mortgage Payments Actually Save You Money?

Yes — biweekly mortgage payments save you tens of thousands in interest and pay off your mortgage approximately 5 years early. The reason is simple math: instead of 12 monthly payments per year, you make 26 biweekly payments — which equals 13 full monthly payments. That one extra payment per year goes entirely to principal reduction.

On a $300,000 mortgage at 6.5% for 30 years, the standard monthly payment is $1,896. Paid monthly for 360 months: total interest $382,633. Biweekly ($948 every two weeks, 26 times per year): you pay off in approximately 25 years instead of 30, saving approximately $68,000 in interest. That is $68,000 saved for doing nothing different except splitting your payment in half and paying every two weeks instead of once a month.

To set up biweekly payments: call your mortgage servicer and ask. Many offer biweekly programs for free. Others charge a small setup fee ($100 to $300). Avoid third-party biweekly services that charge monthly fees — they are unnecessary middlemen. If your servicer does not offer biweekly, you can achieve the same result by adding 1/12 of your monthly payment as extra principal each month: $1,896 / 12 = $158 extra per month.
