About the Inventory Turnover Ratio Calculator
Our free Inventory Turnover Ratio Calculator helps businesses, retailers, and manufacturers measure how efficiently they manage and sell their stock. By utilizing your Cost of Goods Sold (COGS) alongside beginning and ending inventory values, this tool computes your inventory turnover ratio and Days Sales of Inventory (DSI).
How Inventory Turnover Is Calculated
The inventory turnover ratio measures how many times a company's stock is sold and replaced over a specific period. The financial formula used is:
$$\text{Inventory Turnover Ratio} = \frac{\text{Cost of Goods Sold (COGS)}}{\text{Average Inventory}}$$
Where:
- Average Inventory: $(\text{Beginning Inventory} + \text{Ending Inventory}) \div 2$
- Days Sales of Inventory (DSI): $365 \div \text{Inventory Turnover Ratio}$ (represents the average number of days it takes to sell existing stock).
How to Use the Calculator
Simply enter your accounting and inventory figures:
- Cost of Goods Sold (COGS): The direct costs attributable to the production of the goods sold during the period.
- Beginning Inventory: The total value of inventory at the start of the financial period.
- Ending Inventory: The total value of inventory remaining at the end of the period.
Click the Calculate Turnover button to instantly view your average inventory, days to sell, efficiency evaluation, and final inventory turnover ratio.
Frequently Asked Questions (FAQs)
What is considered a good inventory turnover ratio?
A higher ratio generally indicates strong sales and efficient inventory management, though excessively high ratios can lead to stockouts. Typical healthy ratios vary widely by industry (e.g., grocery vs. automotive).
Why is COGS used instead of total revenue?
COGS reflects the direct cost of inventory at cost price, matching the inventory valuation on the balance sheet, whereas revenue includes profit markups which would distort the ratio.
What does a low inventory turnover ratio mean?
A low ratio indicates slow-moving or obsolete stock, poor sales performance, or excess capital tied up in unsold goods that incur holding and storage costs.
