How It Works
How to Calculate Order Fulfillment Rate
Formula
Fulfillment Rate = (Orders Successfully Fulfilled / Total Orders) x 100
Order fulfillment rate measures how reliably your operation delivers on customer orders. It captures stockouts, picking errors, shipping delays, and any other failures that prevent an order from being completed. World-class operations target rates above 99%, while typical businesses range from 90-98%.
Worked Example
A warehouse received 1,000 orders and successfully fulfilled 950.
- 01Fulfillment Rate = (950 / 1,000) x 100 = 95%
- 02Unfulfilled Orders = 1,000 - 950 = 50
