1. Choose a measurement period
Use one consistent period such as a shift, day, or week for both processed volume and capacity.
2. Enter processed returns
Provide the number of return units completed during that period using the same definition of completed work throughout.
3. Enter available capacity
Use the maximum practical number of units the operation could process in the same period under the assumed staffing and equipment plan.
4. Review utilization
The main percentage shows the share of capacity used. The breakdown also shows unused units and the remaining capacity percentage.
