Fill Rate


Fill rate refers to the percentage of customer orders that are fulfilled completely from existing stock upon initial request. It is a crucial metric in inventory management, measuring the effectiveness of an organization in meeting customer demand with available inventory.

Detailed Explanation

The fill rate is a critical indicator of supply chain efficiency and customer satisfaction. It measures the ability of a company to serve its customers’ orders from the stock it has on hand without resorting to backorders or delayed shipments.

A high fill rate is often indicative of excellent inventory management and forecasting, ensuring that products are available when customers need them.

Conversely, a low fill rate can signal issues in inventory planning, supplier reliability, or demand forecasting, leading to potential customer dissatisfaction and lost sales.

Companies strive to optimize their fill rates by balancing the costs of holding inventory against the need to meet customer demand promptly. This involves sophisticated demand forecasting, efficient inventory replenishment strategies, and effective supply chain coordination.


A retail store with a 95% fill rate indicates that 95 out of 100 customer orders were fulfilled immediately from stock on hand.

An online retailer improves its fill rate by adjusting inventory levels based on seasonal demand forecasts, ensuring most customer orders are shipped without delay.
