Utilization rate measures the share of an employee’s available work time charged to defined project work.
Definition
A utilization rate divides time charged to specified project work by a defined measure of available work time. Firms may count billable client work, all project work, or another category in the numerator, and may treat holidays, leave, training, and part-time schedules differently in the denominator. They also choose their reporting period, such as a week, month, or year. Those choices mean rates are most useful when the firm applies its own definition consistently. Owners can use trends to inform staffing, workload, and revenue planning, then consider them alongside project needs and employee capacity. Utilization does not show whether work is profitable, properly scoped, or completed well. It is not a complete measure of employee performance or wellbeing, and one person’s rate should not be interpreted without understanding their role and assignments.
How owners use it
- Set a consistent definition of project time and available time before comparing teams or periods.
- Review utilization trends alongside workload, project demand, and staffing plans.
- For example, 30 project hours / 40 available hours = 75% utilization for that week.
- Compare the firm’s utilization assumptions with the hours available for upcoming project work.
