(Units Shipped / Units Ordered) × 100What is Fill Rate?
Fill Rate measures what percentage of customer orders are completely fulfilled from existing inventory without backorders or split shipments. This metric reflects inventory availability and warehouse fulfillment effectiveness.
High fill rates improve customer satisfaction and reduce fulfillment costs. Most retailers target 95%+ fill rates. Very high rates (99%+) may indicate overstocking.
