Compare a standard monthly mortgage schedule with an accelerated biweekly strategy of 26 half-payments per year, equal to 13 full monthly payments annually.
We'll compare the normal monthly schedule with an accelerated biweekly equivalent.
The accelerated plan effectively adds one extra monthly payment each year.
This schedule models the extra annual payment created by an accelerated biweekly strategy.

A year has 52 weeks. Making a half-payment every two weeks produces 26 half-payments during the year.
Twenty-six half-payments equal 13 full monthly payments, compared with the 12 full payments made under a normal monthly schedule.
The main potential benefit is not simply paying more often. It is that the accelerated strategy results in the equivalent of one additional monthly payment toward the mortgage each year.
Mortgage servicers do not all process partial payments the same way. Some may hold a half-payment until enough money has been received to make a complete monthly payment.
For that reason, this calculator models the common financial effect of 13 monthly payments per year rather than assuming a specific lender's payment-processing method.
Some third-party biweekly payment programs charge setup or transaction fees. You may be able to create a similar accelerated-payoff effect by making additional principal payments directly to your mortgage servicer.
There are 52 weeks in a year, so a true every-two-weeks schedule produces 26 half-payments. Together, those equal 13 full monthly-payment equivalents.
The accelerated strategy results in the equivalent of one extra monthly payment each year. Applying that additional amount to principal may reduce the balance faster and lower future interest.
No. Twice-monthly payments produce 24 half-payments per year, which equals 12 full monthly payments. Every-two-weeks payments produce 26 half-payments, which equals 13 monthly-payment equivalents.
Processing practices vary. Some servicers may hold partial payments until a full monthly payment has been received. Contact your servicer before starting a biweekly strategy.
In many cases, making the equivalent of one additional monthly principal payment each year can create a similar payoff effect, depending on when the payment is applied and your loan terms.
No. The comparison focuses on mortgage principal and interest because accelerated payments generally affect the loan balance rather than taxes, insurance or HOA expenses.
