Understanding Inventory Turnover Ratio
Definition and Core Concept
Inventory Turnover Ratio measures how many times a company sells and replaces its inventory during a specific period, typically a year.
High Ratio
Efficient inventory management, quick cash conversion, reduced storage costs
Low Ratio
Potential inventory problems, excess stock, cash flow issues
Basic Calculation Formula
Cost of Goods Sold divided by Average Inventory Value
Detailed Calculation Methods
Method 1: COGS Approach (Recommended)
Step-by-Step Calculation
- Calculate total Cost of Goods Sold (COGS)
- Calculate average inventory value
- Divide COGS by average inventory
Example Calculation
- COGS: $500,000
- Beginning Inventory: $100,000
- Ending Inventory: $150,000
- Average Inventory: ($100,000 + $150,000) ÷ 2 = $125,000
- Turnover Ratio: $500,000 ÷ $125,000 = 4.0
Method 2: Sales Approach
Note: This method provides higher ratios and is useful for quick estimates, but COGS method is more accurate.
