How to calculate order fill rate
Order fill rate measures the percentage of orders completely fulfilled from available stock without backorder or substitution — a key inventory service-level metric.
How the calculation works
Fill rate = (Orders filled completely ÷ Total orders) × 100.
Example
940 completely filled out of 1,000 total orders: (940÷1,000)×100 = 94%.
