Order Fill Rate

A demand-fulfillment KPI. Line fill and case fill variants use the same structure with different unit definitions.

Fill rate % = shipped quantity ÷ ordered quantity × 100.

Tip: Keep “Units Shipped” and “Units Ordered” on the same basis (period, units, and population) before calculating Order Fill Rate.

Fill rate measures how much of ordered demand you actually shipped (or fulfilled) in the period.

Enter units shipped and units ordered for the same SKU set and window.

Understanding Order Fill Rate

How we calculate. Fill rate % = shipped quantity ÷ ordered quantity × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.

Real-world scenario: A typical Order Fill Rate case uses units shipped 9400 and units ordered 10000. Enter the same figures below to reproduce the worked path.

What is Order Fill Rate?

A demand-fulfillment KPI. Line fill and case fill variants use the same structure with different unit definitions.

  • Same UOM for shipped and ordered
  • Backorders usually reduce fill unless policy says otherwise
  • Can be under 100% when short

The Formula

Order Fill Rate
Fill rate % = (Units shipped ÷ Units ordered) × 100

Worked Example

Scenario: 9,400 units shipped against 10,000 ordered.
Step 1: 9400 ÷ 10000 = 0.94
Step 2: × 100 = 94%
Answer: Order fill rate is 94%.

Common Use Cases

  • Inventory planning: stockout impact
  • Customer service: fulfillment quality
  • S&OP: demand vs supply gaps

Pro Tips

  • State line vs order fill
  • Exclude cancelled demand if appropriate
  • Segment A-items for focus

Limitations: Order Fill Rate results are educational logistics and supply-chain planning aids—not SLAs, carrier contracts, or inventory valuation advice. Confirm definitions with your WMS/TMS and finance policies.

FAQ

Can fill rate exceed 100%?

Not for a strict shipped÷ordered definition. If overships are allowed, treat that as a separate overship metric.

What if units ordered is 0?

Fill rate is undefined—enter positive ordered units.
