Financial Planning Guide: The Power of Accelerated Biweekly Mortgage Payments
A biweekly mortgage payment plan is one of the most effective, painless wealth-building strategies available to homeowners. In a traditional mortgage schedule, you submit 12 monthly payments per calendar year. Under an accelerated biweekly structure, you divide your regular monthly mortgage payment in half and pay that half-amount every two weeks.
Because there are 52 weeks in a year, you make 26 biweekly half-payments. Twenty-six halves equal exactly 13 full monthly payments per year—effortlessly slipping one extra monthly payment onto your mortgage every 12 months without creating a significant budgetary strain.
Because that 13th payment is applied directly to your loan principal, it dramatically accelerates the amortization schedule. On a $350,000 30-year mortgage at 6.75% interest, switching to accelerated biweekly payments shaves roughly 5.5 to 6 years off your mortgage term and saves more than $100,000 in compounding interest.
Beware of third-party mortgage acceleration services that charge setup fees ($300 to $500) or recurring processing fees ($5 to $10 per transaction) to manage biweekly payments. Most loan servicers offer free automated biweekly scheduling directly through their portal. Alternatively, you can achieve the exact same mathematical outcome by simply dividing your monthly principal-and-interest payment by 12 and adding that amount as an extra principal payment to your regular monthly check.

How does an accelerated biweekly mortgage work?
You pay half of your monthly mortgage payment every two weeks. Since there are 52 weeks in a year, you make 26 half-payments, which equals 13 full payments per year—giving you one full extra payment toward principal annually.
What is the difference between bimonthly and biweekly?
Bimonthly means twice a month (24 payments per year, equaling 12 monthly payments). Biweekly means every two weeks (26 payments per year, equaling 13 monthly payments). Only biweekly creates the accelerated extra payment.
Should I pay a fee for a biweekly payment program?
No! Never pay an outside company or lender an enrollment fee or monthly fee to set up biweekly payments. You can achieve the identical financial result for free by adding 1/12th of your payment to your principal each month.
Does my mortgage servicer allow biweekly payments?
Most major servicers allow biweekly payments. However, verify with your lender that payments are applied immediately upon receipt rather than held in escrow until the second half arrives.
Can I do this with an auto loan?
Yes. Biweekly payments work on any standard amortizing loan without prepayment penalties, speeding up payoff and saving interest on auto loans and student loans.
