Cycle service level  = [(No. of items sold and supplied) / (No. of items sold and supplied + No. of items sold but not supplied)] x 100

Where No. of items sold and supplied denotes the number of items that were successfully fulfilled and delivered promptly to meet customer demand. It represents the immediate fulfillment of customer orders, indicating the products that were not only sold but also promptly supplied to customers without delay.

No. of items sold but not supplied refers to the quantity of products that have been sold to customers but, for some reason, have not been successfully delivered or supplied to meet customer demand. We can call it back order also.

What Is the Cycle Service Level?

Cycle Service Level is a metric used to measure the efficiency of the supply chain. It evaluates the percentage of items sold and supplied compared to the total items sold, including those not supplied.

It indicates the likelihood of maintaining sufficient inventory to fulfill demand. For example, if a specific SKU boasts a service level of 90%, it implies a 90% probability that the current inventory will meet or exceed the anticipated demand.
