Capacity Utilization
See how much of your capacity clients actually bill for.
About Capacity Utilization
Utilization is billable hours divided by working capacity, and uncovered hours are the part not sold to clients. Low utilization means earning time is quietly burning in overhead while high levels threaten burnout, so a target keeps balance.
