The 173.33 Payroll Standard
The number of work hours in a month varies because the calendar is not perfectly divisible by four weeks. While some months have only 20 working days, others have up to 23. To simplify payroll, most organizations use the 173.33 rule.
The 173.33 Formula:
(40 Hours/Week × 52 Weeks) ÷ 12 Months = 173.333...
Calculation Formula
To manually find your hours per month, follow these steps:
- Count the total number of weekdays (Mon-Fri) in the month.
- Subtract any public holidays where you do not work.
- Multiply the remaining days by your daily shift length (e.g., 8 hours).
