Biweekly mortgage payments are one of the simplest ways to pay off your home early without feeling a big budget hit. You make half a payment every two weeks — 26 half-payments = 13 full payments per year.

The Math

Monthly payment on $350,000 at 7%: $2,329. Biweekly half-payment: $1,164.50 × 26 = $30,277/year vs $27,948/year monthly — one extra payment annually.

That extra payment goes straight to principal, compounding savings over 30 years.

Biweekly vs DIY Extra Payment

Dividing your monthly payment by 12 and adding that amount each month achieves nearly the same result without a biweekly service.

Avoid third-party biweekly services that charge $300+ in setup fees.
