Inventory Turns

Inventory Turns (Inventory Turnover): The number of times that a companies inventory cycles or turns over per year. It is one of the most commonly used Supply Chain Metrics.

Calculation: A frequently used method is to divide the Annual Cost of Sales by the Average Inventory Level.
Example: Cost of Sales = $36,000,000. Average Inventory = $6,000,000.
$36,000,000 / $6,000,000 = 6 Inventory Turns

OR
Inventory Turns can be a moving number.
Example: Rolling 12 Month Cost of Sales = $16,000,000. Current Inventory = $4,000,000
$16,000,000 / $4,000,000 = 4 Inventory Turns

Projected Inventory Turns: Divide the “Total Cost of 12 Month Sales Plan” by the “Total Cost of Goal Inventory”
Example: The Total Cost of 12 Month Sales Plan is $40,000,000. Total Cost of Goal Inventory = $8,000,000
$40,000,000 / $8,000,000 = 5 Projected Turns

Turns can be viewed using Cost Value, Retail Value, or even in Units. Just make sure that you’re using the same Unit of Measure in both the Numerator and the Denominator.

Although results vary by industry, typical manufacturing companies may have 6 inventory turns per year. High volume/low margin companies (like grocery stores) may have 12 inventory turns per year or more.

Consult a qualified benchmarking company to help you set your target for your inventory turns.
