Order picking accuracy is a fundamental KPI measuring the percentage of orders picked without errors. It is calculated by dividing the number of accurately picked orders by the total number of orders fulfilled. This KPI directly impacts customer satisfaction and order fulfilment. High order picking accuracy ensures that customers receive the correct products in a timely manner, leading to improved customer satisfaction, reduced returns, and increased operational efficiency.

Formula: Number of accurately picked orders / Total numbers of orders fulfilled


Inventory turnover is a critical KPI that assesses the efficiency of inventory management. It measures how quickly inventory is sold and replenished within a specific period. Inventory turnover can be worked out by dividing the cost of goods sold (COGS) by the average inventory value. A higher inventory turnover ratio indicates that inventory is being efficiently utilised and that capital is not tied up in excessive stock. This KPI helps businesses optimise inventory levels, reduce carrying costs, and prevent obsolescence.

Formula:  Cost of goods sold / Average Inventory

The time it takes for an order to move through the entire order processing cycle, from order placement to delivery, is measured as the order cycle time – including order processing, picking, packing, and shipping. The calculation involves tracking the average time taken for each step and summing them up. Monitoring order cycle time is crucial for evaluating order processing speed and efficiency. By reducing cycle time, businesses can improve customer satisfaction, minimise order lead times, and enhance overall operational effectiveness.

The on-time shipping rate measures the percentage of orders shipped within the promised or expected delivery time. It is calculated by dividing the number of orders shipped on time by the total number of orders. This KPI is directly linked to customer satisfaction and reputation. Maintaining a high on-time shipping rate builds trust with customers, enhances brand loyalty, and strengthens customer relationships. It also helps businesses avoid penalties associated with late shipments and improve overall operational efficiency.

Evaluating the efficiency of warehouse operations can be done with the cost per order, achieved by calculating the average cost incurred to fulfil a single order. It includes expenses related to labour, equipment, packaging materials, shipping, and other operational costs. Monitoring the cost per order helps businesses identify areas of inefficiency and implement cost-saving measures. By optimising processes and reducing operational expenses, businesses can enhance profitability and maintain a competitive edge.

The carrying cost of inventory assesses the expenses associated with storing and maintaining inventory over a specific period. It includes costs such as storage space, insurance, depreciation, obsolescence, and financing. Calculating the carrying cost of inventory helps businesses understand the financial impact of inventory holding and adjust inventory levels accordingly. By reducing carrying costs, businesses can improve cash flow, minimise inventory-related risks, and enhance overall warehouse profitability.

Formula: (Inventory Holding Cost / Total Value Of Inventory) x 100

Labour productivity measures the efficiency of workforce management in the warehouse by dividing the total output by the total labour hours. Monitoring labour productivity helps businesses identify opportunities to optimise staffing levels, streamline processes, and improve overall productivity. By analysing labour productivity KPIs, businesses can identify bottlenecks, implement training programs, and allocate resources effectively to maximise workforce efficiency.

To keep track of the extent to which a warehouse’s available storage capacity is being utilised, a KPI called capacity utilisation comes into play. It is calculated by dividing the actual inventory volume by the maximum storage capacity and multiplying it by 100. Monitoring capacity utilisation helps businesses optimise warehouse space and storage allocation. By maintaining an optimal level of capacity utilisation, businesses can minimise storage costs, maximise operational efficiency, and avoid stockouts or overcrowding.

Formula: (Actual Output / Maximum Possible Output) x 100

Equipment utilisation measures the efficiency and effectiveness of warehouse equipment. It involves tracking the usage of equipment such as forklifts, conveyors, and automated systems. Equipment utilisation is calculated by dividing the total operational hours of the equipment by the total available hours and multiplying it by 100. By monitoring equipment utilisation, businesses can identify underutilised or over utilised equipment, plan maintenance schedules effectively, and ensure smooth operations while minimising downtime and repair costs.

Formula: Total Hours of Usage / Total Number of Available Hours

Return on Investment is one of the most used KPI’s so this shouldn’t be new to your business, however it would be remiss to overlook this! A comprehensive KPI, ROI assesses the profitability and effectiveness of warehouse operations and investments. It measures the financial return generated from the capital invested in the warehouse. ROI is calculated by dividing the net profit from warehouse operations by the total investment cost and multiplying it by 100. Monitoring ROI helps businesses evaluate the success of their investments, identify areas for improvement, and make informed decisions regarding future investments or expansion plans.

Formula: Net Return / Cost of Investment
