Utilization rate: what it is, how to calculate it accurately

So what's the best way to calculate utilization rate? The basic formula is pretty simple: it's the number of billable hours divided by the total number of available hours (x 100). So, if an employee billed for 32 hours from a 40-hour week, they would have a utilization rate of 80%.
