Practical Examples
Example 1: Calculating Inventory Turnover
Let’s say a company has \(100,000 in inventory and sells \)500,000 worth of goods in a year. The inventory turnover ratio is:
Inventory Turnover Ratio = Sales / Average Inventory
Average Inventory = (Beginning Inventory + Ending Inventory) / 2
If the beginning inventory is \(50,000 and the ending inventory is \)60,000, then:
Average Inventory = ($50,000 + $60,000) / 2 = $55,000
Inventory Turnover Ratio = $500,000 / $55,000 = 9.09
This means the company sold its inventory 9.09 times in the year.
Example 2: Determining the Reorder Point
A company has a lead time of 2 weeks and a daily demand of 100 units. To determine the reorder point, we need to calculate the safety stock:
Safety Stock = Lead Time Demand * Safety Stock Factor
Lead Time Demand = Daily Demand * Lead Time
Safety Stock Factor = Z-Score * Standard Deviation of Demand
Let’s assume a Z-Score of 3 (for a 99.73% service level) and a daily demand standard deviation of 20 units:
Lead Time Demand = 100 units/day * 2 weeks = 2,000 units
Safety Stock Factor = 3 * 20 units = 60 units
Safety Stock = 2,000 units * 60 units = 120,000 units
Reorder Point = Lead Time Demand + Safety Stock = 2,000 units + 120,000 units = 122,000 units
This means the company should place an order when the inventory level reaches 122,000 units.
