How to Calculate Exactly How Much I Make a Month

by Grace Ferguson; Updated September 26, 2017

An employer may choose to pay his employees on a weekly, biweekly or semi-monthly basis. Consequently, if the employee is not paid monthly, he can become confused as to precisely what his earnings are for the month. It is important to consider your pay frequency when determining how much you earn for the month.

Step 1

Calculate by weekly pay cycle. There are 4.3 weeks in a month, which equals 52 weeks per year. Multiply your weekly gross pay by 4.3 weeks to arrive at your monthly gross pay.

Step 2

Determine by biweekly pay cycle. A biweekly pay cycle occurs every two weeks; therefore, divide 4.3 weeks by 2, which equals 2.15. Multiply your biweekly pay amount by 2.15 to arrive at the monthly average.

Step 3

Calculate by semi-monthly pay cycle. A semi-monthly pay period has 24 pay dates, with each generally occurring on the 1st and the 15th of each month. Combine your earnings for both pay dates in the month to get your monthly pay.
