How it works

Biweekly payments are half the monthly payment, made 26 times a year. Interest is calculated on a shorter cycle and the extra month of payments lowers the balance faster.

Worked example

On a 300,000 loan at 6.5 percent over 30 years, biweekly payments finish years early and save close to 88,000 in interest.
