Order lead time measures the time it takes to fulfill a customer's order from the moment it is placed until it is shipped. Reducing lead time improves customer satisfaction and enables faster order processing.
Formula: Sum of Total Time from Order to Delivery / Number of Orders
15. Stock-Out Rate
Stock out rate measures the frequency of out-of-stock items. Having the high frequency of out of stock items can lead to reduction in overall sales, poor customer experience, reduced brand visibility and negative impact on brand image.
Formula: (Number of Stock-Outs / Total Number of SKU) * 100%
16. Average Cost per Order
Average cost associated with processing an order is one of the warehouse efficiency metrics. Lower costs per order fulfillment means having higher profit margins and vice versa. Optimizing the warehouse processes can lead to better efficiency and less avg. cost per order.
Formula: Total Order Processing Cost / Number of Orders
17. Labor Cost per Order
The labor cost is one of the key warehouse management metrics which is associated with the human effort put in by the warehouse staff and managers to fulfill the orders. The higher the average labor cost is per order, the lesser profit margins there will be.
Automated warehouse systems like warehouse picking automation, inventory management software, automated warehouse receiving process, etc. can reduce labor cost.
Formula: Total Labor Cost / Number of Orders
18. Fill Rate
Fill rate measures the percentage of customer orders that are fulfilled completely on the first shipment. It indicates the warehouse's ability to meet customer demands without backorders or partial shipments.
Formula: Total order fulfilled in first shipment/ Total number of order fulfilled *100%
19. On-Time Shipment Rate
The on-time shipment rate is one of the most important warehouse metrics. It measures the percentage of orders shipped on or before the promised shipping date. Better customer satisfaction and repeat purchases can be achieved through high on-time shipment rate.
Formula: (Total on-time shipments / Total orders) * 100
On-time shipments are where cycle time is less than promised delivery SLA
20. Damage Rate
Damage rate is one of the warehouse metrics that measures the percentage of goods received or shipped that are damaged. Having a high rate of damage can lead to loss of clients, negative impact on profit margins, and less warehouse workflow efficiency.
