Fill Rate
The percentage of ordered quantity actually delivered to the customer in full and on time, a core service-level metric.
Full definition
Fill rate measures how completely a distributor or brand meets its downstream orders. The standard formula is: (quantity delivered / quantity ordered) x 100. A fill rate of 97% means that for every 100 units ordered across the network, 97 were actually shipped on time and in full. Chronically low fill rates erode distributor trust and push retailers to stock competitor brands.
Fill rate is a richer metric than simple stock-out counts because it weights by quantity. A single SKU being out of stock on one order is very different from every SKU shortfalling 20%. Leading FMCG brands target 98%+ fill rate as part of their customer service level agreement.
Fill rate should always be read alongside line item fill rate, the stricter version that penalizes even partial fulfillment of any single SKU.
Real-world example
A distributor who receives orders for 10,000 cases and ships 9,700 has a fill rate of 97%.
