Inventory KPIs Every Business Should Track
Measure What Matters
Numbers like turnover ratio, stockout rate, and carrying cost show how well your inventory is doing. This section explains what each metric measures and how to calculate it. It also explains what a good or bad number tends to signal.
Together, these guides cover the core KPIs worth tracking. It doesn't matter the size or type of business you run.
Turning Numbers Into Decisions
Numbers can feel abstract until you connect them to real decisions. Inventory KPIs turn raw data, like sales and stock counts, into signals you can act on. They tell you when something is working. They also tell you when something needs a closer look.
Take turnover ratio and Days Inventory Outstanding. Both measure how fast stock moves, just from slightly different angles. Together, they give you a clearer picture than either one alone. Stockout rate looks at the opposite problem. It tracks how often demand went unmet because stock ran out. Carrying cost puts a dollar figure on holding inventory. It covers storage space. It also covers the risk of stock losing value over time.
No single KPI tells the whole story. High turnover paired with a rising stockout rate might mean you're cutting it too close. Low turnover paired with high carrying cost usually points to overstock. Reading these numbers together matters more than watching just one.
Check these metrics on a regular schedule, instead of only when something feels wrong. That habit tends to catch small issues before they grow into bigger, costlier ones.
