The percentage of hours worked is the number of hours actually worked divided by the total hours available during a specified period of time. Employers and employees can use this calculation to help gauge the employee's quality of life and work-life balance. Additionally, as the percentage of hours worked increases above certain levels, an employee can become less productive as he starts to experience a burnout factor.

Determine the number of hours worked during a pay period. You will normally find the hours worked listed on your pay stub. Salaried employees should keep track of the actual hours worked during the pay period. For example, assume you worked 45 hours during the pay period.

Determine the number of actual hours in the pay period. For example, assume your company pays every week. Multiply the number of hours in a a day by the number of days in the pay period. Continuing the same example, 24 multiplied by 7 equals 168.

Divide the hours worked by the actual number of hours in the pay period. Continuing the same example, 45 divided by 168 and multiplied by 100 equals 26.8 percent. This figure represents the percentage of hours worked during the pay period.
