How to Calculate Inventory Turnover Ratio with Example
Inventory turnover ratio is a key accounting metric used to evaluate how efficiently a business manages and sells its stock. For students, understanding inventory turnover ratio is vital for school and competitive exams, and is relevant in real-world business decision-making. At Vedantu, we guide you through concepts essential for exam success and practical business understanding.
| Aspect | Inventory Turnover Ratio | Stock Turnover | Inventory Days |
|---|---|---|---|
| Definition | Number of times inventory is sold/replaced in a period | Alternative term; often used interchangeably | Average number of days inventory is held |
| Formula | COGS ÷ Average Inventory | COGS ÷ Average Inventory | 365 ÷ Inventory Turnover Ratio |
| Indicates | Efficiency in stock management | Same as above | Speed of inventory movement |
What is Inventory Turnover Ratio?
The inventory turnover ratio measures how many times a business sells and replaces its inventory over a specific period, usually a year. It highlights operational efficiency—in other words, how quickly stock is converted into sales. This concept is central to commerce and financial management.
Inventory Turnover Ratio Formula and Calculation
The most common formula for inventory turnover ratio uses cost of goods sold (COGS) and average inventory for the period. This ensures consistency, as both are valued at cost rather than at sales price.
| Formula | Explanation |
|---|---|
| Inventory Turnover Ratio = COGS ÷ Average Inventory | COGS: Total cost of goods sold during the period Average Inventory = (Opening Inventory + Closing Inventory) ÷ 2 |
Step-by-Step Calculation
- Find the Cost of Goods Sold (COGS) from the income statement.
- Calculate average inventory: add opening and closing inventory, divide by 2.
- Divide COGS by average inventory.
Interpretation of Inventory Turnover Ratio
A higher inventory turnover ratio indicates efficient inventory management and strong sales. A lower ratio may suggest weak demand or overstocking. Comparing the ratio with industry standards is important for accurate analysis. For exams, remember that retail industries usually have higher turnover ratios compared to auto dealerships or luxury goods.
- A high ratio: Fast inventory movement, but risk of stockouts.
- A low ratio: Slow movement, risk of excess or obsolete stock.
- Compare with industry average for effective judgment.
Examples of Inventory Turnover Ratio Calculation
Here's a clear example to help you master inventory turnover calculations for exams and assignments:
| Details | Amount (₹) |
|---|---|
| Opening Inventory | 40,000 |
| Closing Inventory | 60,000 |
| Cost of Goods Sold (COGS) | 2,50,000 |
Calculation Steps
- Average Inventory = (40,000 + 60,000) ÷ 2 = 50,000
- Inventory Turnover Ratio = 2,50,000 ÷ 50,000 = 5 times
This means inventory was sold and replaced 5 times during the year.
Why is Inventory Turnover Ratio Important?
The inventory turnover ratio is essential for students preparing for accountancy and ratio analysis exams, and helps in real business by measuring stock management. It guides companies in maintaining ideal inventory levels, avoiding overstocking, and meeting market demand.
Limitations of Inventory Turnover Ratio
- Industries differ: Benchmarks for turnover vary between industries; always compare ratios within the same sector.
- Seasonal factors: Peak and off-season inventory levels can distort the ratio.
- Calculation methods: Some use sales instead of COGS, which can inflate results.
- Does not reflect lead times: May not show how quickly new stock is restocked.

Related Ratios and Inventory Days
Inventory turnover ratio is related to other efficiency ratios like profitability ratios. Another useful metric is “Inventory Turnover in Days,” calculated as 365 divided by the turnover ratio. It shows the average days inventory remains unsold. For deeper exam understanding, study Analysis of Financial Statements.
| Ratio | Formula | Measures |
|---|---|---|
| Inventory Turnover Ratio | COGS ÷ Average Inventory | Frequency of stock sales/replacement |
| Inventory Turnover in Days | 365 ÷ Inventory Turnover Ratio | Average holding period of stock |
Tips for Exams and Assignments
- Memorize the formula: Inventory Turnover Ratio = COGS ÷ Average Inventory
- Always use COGS, not Sales, unless otherwise specified
- Present calculation neatly in stepwise tables for clarity
- Understand interpretation: Know when high or low ratios are good or bad
- Use real numbers from balance sheets for practice

FAQs on Inventory Turnover Ratio: Definition, Formula & Example
1. What is the inventory turnover ratio?
The inventory turnover ratio is a key financial metric showing how efficiently a company manages its inventory by measuring how many times it sells and replaces its stock during a given period. A high ratio suggests strong sales, while a low one might indicate overstocking or weak demand.
2. How is the inventory turnover ratio calculated?
The inventory turnover ratio is calculated by dividing the Cost of Goods Sold (COGS) by the average inventory. To find the average inventory, add the beginning and ending inventory values and divide by two. The formula is: Inventory Turnover Ratio = Cost of Goods Sold / Average Inventory.
3. What is considered a "good" inventory turnover ratio?
There's no single "good" inventory turnover ratio. The ideal ratio varies significantly by industry. A high ratio might be considered good in some sectors (like fast-moving consumer goods), but it could be problematic in others (like luxury goods). Always compare a company's ratio to its industry benchmarks to get a meaningful comparison. Consider the inventory turnover days as well.
4. Is a high inventory turnover ratio better or worse than a low one?
Whether a high or low inventory turnover ratio is better depends on the context. A high ratio generally suggests strong sales and efficient inventory management, minimizing storage costs. However, an excessively high ratio might indicate understocking, leading to lost sales. Conversely, a low ratio could signal overstocking, tying up capital. Analyzing this in conjunction with profitability ratios is crucial.
5. What does an inventory turnover ratio of 1.5 or 2 mean?
An inventory turnover ratio of 1.5 means the company sells and replaces its inventory 1.5 times per year. A ratio of 2 indicates the inventory is sold and replaced twice a year. The interpretation needs to consider industry benchmarks and company-specific factors. These values might indicate relatively slow turnover depending on the sector.
6. How does industry type affect average inventory turnover ratios?
Industry type significantly impacts average inventory turnover ratios. Fast-moving consumer goods (FMCG) companies typically have much higher turnover ratios than industries with slower-moving products, such as luxury goods or capital equipment. Comparing a company's ratio to its industry average provides a much more relevant interpretation.
7. Is 12 a good inventory turnover ratio?
Whether an inventory turnover ratio of 12 is good depends entirely on the industry. For some sectors, that would be exceptionally high, suggesting possible understocking and lost sales opportunities. In other industries, it might be a standard or even low rate. Always compare against industry averages for accurate assessment.
8. What does an inventory turn of 2 mean?
An inventory turnover of 2 means a company's inventory is sold and replaced, on average, twice during the accounting period (usually a year). This implies that the company is selling its inventory at a moderate pace. Comparing this to industry benchmarks offers valuable context.
9. How to calculate inventory turnover ratio from balance sheet?
You can't calculate the inventory turnover ratio from the balance sheet alone. You need both the balance sheet (for beginning and ending inventory) and the income statement (for the Cost of Goods Sold (COGS)). The formula remains: COGS / Average Inventory.
10. What are the limitations of using the inventory turnover ratio?
The inventory turnover ratio has limitations. It doesn't account for factors like obsolescence, spoilage, or seasonal demand fluctuations. Using only this ratio for business decisions might not be adequate and it should be used in conjunction with other accounting ratios and analyses.
