We use PTO accrual per hour worked.   Because the employee's run a route their work hours can vary.  They can work 6 hours one day and 10 hours another day.

In order to be consistent in paying PTO for each employee, how should we calculate the amount to be paid per day?

Assumption:  Employee accrued 19.65 hours over 4 months.  Worked a total of 589.61 hrs during that time period.

To calculate how much time is available for 1 day: 

Divide 589.61 hrs by 16 weeks, by 5 days = 7.37 hrs (average hours worked)

Would this be accurate?  Or is there another way that would be better?
