No, you meant biweekly, at least if you want those numbers to add up. While most months will only have two paychecks, two months will have three.

Biweekly means you get paid once every two weeks, which is 26 times a year. 52 weeks in a year divided by once every two weeks is 26 times. Your gross pay of $3077 times 26 is $80K nearly exactly.
