Fill Rate Calculator

How to use

Enter your fulfilled and total order counts, then tap Calculate. The fill rate reflects the percentage of orders you shipped without backorders.

Methodology

We compute fill rate as fulfilled orders divided by total orders, multiplied by 100 to express the result as a percentage.

• Total orders must be greater than 0.
• Fulfilled orders cannot exceed total orders; otherwise the result is capped at 100%.
• The output rounds to two decimals for reporting clarity.

This calculator supports supply chain professionals who track fulfillment performance.

All calculations follow industry standards and are based on the formula below.

Fill Rate = (Fulfilled Orders / Total Orders) × 100

Glossary

• Fulfilled Orders: Orders shipped in full from inventory.
• Total Orders: The total orders received.
• Fill Rate: The ratio expressed as a percentage.

Example

With 80 fulfilled orders out of 100, fill rate equals (80 ÷ 100) × 100 = 80%.
