Which metric indicates how efficiently stock is used by showing how quickly it is consumed and replenished?

• A. Lead time
• B. Inventory turnover
• C. Safety stock level
• D. Fill rate

Answer: (B)

Inventory turnover measures how quickly stock is consumed and replenished, signaling how efficiently inventory is used. It answers the direct question of usage rate by showing how many times you replace your inventory over a period. Practically, it’s usually calculated as the cost of goods sold divided by the average inventory during that period. A higher turnover means stock moves faster, so you’re consuming and replenishing more rapidly, which often corresponds to better inventory management and lower holding costs. Lead time is about the time gap between placing an order and receiving it, which affects how quickly you can react to demand but doesn’t indicate how fast inventory is being used. Safety stock level is the buffer kept to guard against uncertainty, not the rate of consumption. Fill rate reflects service performance—how much demand you fulfill on time—not the speed at which stock is turned over. So, the metric that best captures how efficiently stock is used through rapid consumption and replenishment is inventory turnover.
