Inventory turns, also known as inventory turnover, is a crucial financial ratio that measures how many times a company has sold and replaced its inventory during a specific period. It's a vital indicator of a company's operational efficiency, inventory management effectiveness, and overall financial health. A higher inventory turnover generally suggests that a company is selling goods quickly, minimizing storage costs, and reducing the risk of obsolescence.
Why is Inventory Turns Important?
- Operational Efficiency: A high turnover rate indicates efficient sales and inventory management, meaning products aren't sitting in warehouses for too long.
- Liquidity: Faster inventory turns mean that inventory is quickly converted into sales, improving cash flow and liquidity.
- Cost Reduction: Holding inventory incurs costs (storage, insurance, spoilage, obsolescence). High turnover reduces these carrying costs.
- Profitability: Efficient inventory management can lead to higher profits by reducing waste and ensuring products are available when customers want them.
- Risk Management: Slow-moving inventory can become obsolete or damaged, leading to write-offs. High turnover mitigates these risks.
How to Calculate Inventory Turns
The most common formula for calculating inventory turns uses the Cost of Goods Sold (COGS) and Average Inventory:
Inventory Turns = Cost of Goods Sold (COGS) / Average Inventory
To calculate Average Inventory, you typically use the beginning and ending inventory values for the period:
Average Inventory = (Beginning Inventory Value + Ending Inventory Value) / 2
Let's break down the components:
- Cost of Goods Sold (COGS): This is the direct cost attributable to the production of the goods sold by a company. It includes the cost of materials, direct labor, and manufacturing overhead. COGS is found on a company's income statement.
- Beginning Inventory Value: The total value of inventory a company has at the start of an accounting period.
- Ending Inventory Value: The total value of inventory a company has at the end of an accounting period.
Interpreting Your Inventory Turns Ratio
What constitutes a "good" inventory turnover ratio varies significantly by industry. For example:
- Grocery Stores: Often have very high turnover rates (e.g., 10-20 times or more) because they sell perishable goods quickly.
- Car Dealerships: Might have lower turnover rates (e.g., 4-6 times) due to the high value and slower sales cycle of vehicles.
- Jewelry Stores: Typically have very low turnover rates (e.g., 1-2 times) because items are high-value, durable, and have a longer sales cycle.
Generally:
- High Turnover: Can indicate strong sales, effective inventory management, and minimal holding costs. However, excessively high turnover might suggest insufficient stock, leading to lost sales (stockouts).
- Low Turnover: May signal weak sales, overstocking, obsolete inventory, or inefficient purchasing. This can lead to higher carrying costs and potential write-downs.
It's crucial to compare your company's inventory turnover to industry benchmarks and its historical performance to gain meaningful insights.
Days Sales of Inventory (DSI)
Closely related to inventory turns is the Days Sales of Inventory (DSI), also known as "Days Inventory Outstanding" or "Average Age of Inventory." This metric tells you, on average, how many days it takes for a company to sell its inventory.
Days Sales of Inventory (DSI) = 365 / Inventory Turns
A lower DSI is generally better, as it means inventory is being sold more quickly. Like inventory turns, the ideal DSI varies by industry.
How to Improve Inventory Turns
If your inventory turns are lower than desired, consider these strategies:
- Optimize Purchasing: Implement just-in-time (JIT) inventory systems or improve forecasting to purchase only what's needed, when it's needed.
- Improve Sales and Marketing: Boost demand for your products through effective promotions, pricing strategies, and marketing campaigns.
- Clear Out Slow-Moving Inventory: Offer discounts, bundles, or promotions to sell off old or obsolete stock.
- Enhance Supply Chain Efficiency: Streamline logistics and supplier relationships to reduce lead times and improve delivery reliability.
- Better Forecasting: Utilize data analytics and historical sales trends to create more accurate demand forecasts, preventing both overstocking and stockouts.
- Product Rationalization: Review your product offerings and consider discontinuing items that consistently have low turnover.
Example Calculation
Let's say a company has the following financial data for a year:
- Cost of Goods Sold (COGS): $500,000
- Beginning Inventory Value: $100,000
- Ending Inventory Value: $150,000
Using the calculator above, we would input these values:
- Calculate Average Inventory:
($100,000 + $150,000) / 2 = $125,000 - Calculate Inventory Turns:
$500,000 (COGS) / $125,000 (Average Inventory) = 4.00 times - Calculate Days Sales of Inventory (DSI):
365 days / 4.00 (Inventory Turns) = 91.25 days
This means the company sold and replaced its entire inventory 4 times during the year, and on average, it took about 91 days to sell its inventory.
