Fill rate: Key figure for delivery capability and availability in Procurement
November 19, 2025
The fill rate is a key performance indicator in Procurement and supply chain management that measures the proportion of fully fulfilled orders or purchase requisitions. It provides information about the delivery capability of suppliers and the availability of materials or products. Find out below what the fill rate means exactly, how it is calculated and what strategic importance it has for Procurement .
Key Facts
- Measures the percentage of fully fulfilled orders or requisitions
- Key performance indicator for evaluating supplier performance and availability
- Can be measured at different levels: Article, order or quantity level
- Typical target values are between 95-99% depending on industry and criticality
- Direct impact on customer satisfaction and operating costs

Definition and meaning of the fill rate (key figure)
The fill rate quantifies the ability to meet customer needs or internal requirements in full and on time.
Basic concepts of the fill rate
The fill rate is calculated as the ratio between fulfilled and requested quantities or orders. It can be viewed at different aggregation levels:
- Article fill rate: availability of individual products or materials
- Order fill rate: Complete fulfillment of complete orders
- Quantity fill rate: proportion of the total quantity delivered to the total quantity ordered
Fill rate vs. service level
While the service level measures general performance, the fill rate focuses specifically on the completeness of deliveries. Adherence to delivery dates adds the time dimension to this consideration.
Importance of the fill rate in Procurement
In procurement management, the fill rate serves as a critical indicator for the reliability of the supply chain. It directly influences production planning, stock levels and ultimately customer satisfaction. A low fill rate can lead to production downtime, increased safety stocks and emergency procurements.
Measurement, database and calculation
Precise measurement of the fill rate requires systematic data collection and standardized calculation methods.
Calculation formulas and variants
The basic formula is: Fill Rate = (Quantity Fulfilled / Quantity Requested) × 100%. Different variants are used depending on the application:
- Immediate fill rate: availability at the time of request
- Periodic fill rate: fulfillment within a defined period of time
- Weighted fill rate: consideration of the value of different items
Data sources and system integration
The calculation is based on data from ERP systems, warehouse management and order processing. Modern systems enable automated recording of the three-way match rate and integration with the PO cycle time.
Segmentation and categorization
A differentiated view is often taken using ABC analysis to distinguish between critical and less important articles. This enables targeted control of the fill rate according to priorities.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Interpretation and target values for fill rates
The correct classification of fill rate values enables well-founded decisions to be made in procurement management.
Industry-specific benchmarks
Typical target values vary depending on the industry: automotive suppliers often aim for 99%+, while 95-98% is common in retail. The criticality of the items and the minimum order quantity have a significant influence on the target.
Correlation with other key figures
The fill rate should always be considered in the context of related metrics. A high fill rate combined with poor on-time delivery indicates planning problems. The backorder rate adds important insights to the analysis.
Continuous improvement and monitoring
Regular analysis of fill rate trends enables proactive measures to be taken. Integration in supplier evaluations and linking with the supplier rating create incentives for continuous improvement.
Measurement risks and bias in fill rates
The correct interpretation of the fill rate requires an understanding of possible distortions and measurement inaccuracies.
Data quality and system errors
Incomplete or incorrect data entries can distort the fill rate. Particularly critical are discrepancies between the ordering system and goods receipt postings, which can lead to an apparently lower goods receipt throughput time.
Temporal distortions and reporting date effects
The choice of measurement period has a significant influence on the fill rate. Seasonal fluctuations or one-off events can lead to misleading conclusions. A correlation with the complaint rate helps to validate the results.
Optimization paradox and conflicting goals
Focusing too much on high fill rates can lead to excessive stock levels and rising costs. The tension between availability and efficiency requires a balanced view of various KPIs such as inventory turns.

Practical example
An automotive manufacturer monitors the fill rate of its A-parts daily via a dashboard. In the case of a critical component, the fill rate drops from 99% to 92%. The system automatically triggers an escalation and Procurement contacts the supplier. A production standstill is avoided thanks to a rapid response and alternative procurement sources.
- Automated monitoring of critical components
- Escalation processes if target values are not met
- Proactive communication with suppliers and internal stakeholders
Current developments and effects
Digitalization and new technologies are fundamentally changing the measurement and control of the fill rate.
Artificial intelligence and predictive analytics
AI-based systems enable a more precise prediction of fluctuations in demand and optimize the fill rate through intelligent inventory management. Machine learning algorithms analyze historical data and external factors to identify bottlenecks at an early stage.
Real-time monitoring and transparency
Modern dashboard solutions offer real-time monitoring of the fill rate and enable quick reactions to deviations. Integration with Forecast Accuracy significantly improves planning quality.
Sustainability and resilience
Companies are increasingly balancing high fill rates with sustainable procurement strategies. The COVID-19 pandemic has highlighted the importance of resilient supply chains and diversified supplier portfolios for a stable fill rate.
Conclusion
The fill rate is an indispensable key figure for successful supply chain management and Procurement. It enables the objective assessment of supply capability and forms the basis for strategic procurement decisions. Modern technologies such as AI and real-time analytics open up new possibilities for more precise measurement and proactive control. A balanced view in the context of other key figures ensures optimal results for the company.
FAQ
What is the difference between fill rate and service level?
The fill rate specifically measures the completeness of deliveries, while the service level is a more comprehensive measure of supplier performance. The service level can include additional factors such as quality and on-time delivery, while the fill rate focuses on quantity fulfillment.
How is the fill rate calculated in practice?
The calculation is made as a quotient of the quantity fulfilled and the quantity requested, multiplied by 100. Example: 950 of 1000 parts ordered are delivered, resulting in a fill rate of 95%. It is important that the measurement period is defined uniformly and that partial deliveries are taken into account.
What target values are appropriate for the fill rate?
Target values depend on the sector, article criticality and cost-benefit ratio. A-items often require 98-99%, while 90-95% may be sufficient for C-items. Setting the target too high can lead to uneconomically high stock levels.
How can the fill rate be systematically improved?
Improvements require a holistic approach: optimization of requirements planning, supplier development, diversification of procurement sources and adjustment of safety stocks. Regular analyses and continuous monitoring are essential for sustainable improvements.
