Compare a standard monthly mortgage schedule with an accelerated biweekly strategy of 26 half-payments per year, equal to roughly 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 as an equivalent additional amount spread across the year.
| Year | Beginning Balance | Scheduled Payments | Extra Principal | Principal Paid | Interest Paid | Ending Balance |

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 additional amount is generally applied toward principal. Reducing principal sooner means less balance remains on which future interest can be calculated.
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 making the equivalent 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-payment effect by making an additional principal payment directly to your mortgage servicer.
This is an educational estimate. Actual mortgage servicing, payment application, interest accrual and lender policies may differ.
There are 52 weeks in a year, so a payment made every two weeks results in 26 half-payments. Those 26 half-payments equal approximately 13 full monthly payments.
The strategy effectively makes one additional monthly payment each year. The extra amount reduces principal sooner, which can reduce future interest.
No. Paying twice a month creates 24 half-payments per year, equal to 12 full payments. Paying every two weeks creates 26 half-payments, equal to 13 full payments.
Policies vary. Some servicers accept biweekly payments while others may hold partial payments until a full monthly payment is available. Check with your mortgage servicer before changing your payment schedule.
Generally, making one additional full principal-and-interest payment per year can create a similar accelerated-payoff effect, depending on when and how the extra amount is applied.
No. The accelerated-payoff calculation focuses on mortgage principal and interest. Property taxes, homeowners insurance, mortgage insurance and HOA dues are not included.
