15 KPIs in Supply Chain to Track in 2026

What are Supply Chain KPIs?

Supply chain KPIs are measurable performance indicators used to evaluate how effectively a supply chain operates and how well it supports business objectives. They help organizations track important areas such as cost, service, inventory management, delivery performance, and overall operational efficiency. In practice, these KPIs give managers a clearer view of what is working well, where bottlenecks exist, and which processes need improvement.

Common supply chain KPIs include on-time delivery, fill rate, inventory turns, cash-to-cash cycle time, and forecast accuracy because these metrics reflect both operational performance and customer service outcomes. Companies use them to monitor day-to-day execution, support better planning, reduce risk, and align supply chain activities with broader financial and strategic goals. A strong KPI system also improves visibility across functions, making it easier to connect procurement, production, logistics, and customer fulfillment into one performance-driven process.
