How to Calculate Inventory Turnover?
Inventory turnover is one of the most valuable key performance indicators (KPIs) for measuring the efficiency of a company’s inventory management. It shows how quickly products are sold and replaced over a given period. The better your inventory turnover aligns with your business activity, the more effectively you can improve cash flow, reduce storage costs, and minimize the risks of overstocking or stockouts.
For SMEs, cooperatives, and small businesses, monitoring this KPI helps make better purchasing decisions and anticipate customer demand more accurately. When combined with an ERP or inventory management software, inventory turnover becomes a powerful management tool.
What Is Inventory Turnover?
Inventory turnover measures the number of times a company’s inventory is completely sold and replenished during a given period, typically one year.
This KPI helps answer several important business questions:
- Are products selling quickly enough?
- Are certain items sitting in storage for too long?
- Are purchasing decisions aligned with actual customer demand?
A high inventory turnover generally indicates that products are moving quickly. On the other hand, a low turnover ratio may suggest excess inventory, slow-moving products, or inefficient purchasing practices.
However, the ideal inventory turnover varies by industry. A food distributor will naturally have a higher turnover than a cosmetics manufacturer or a cooperative selling seasonal products.
Inventory Turnover Formula
Calculating inventory turnover is relatively simple.
Inventory Turnover = Cost of Goods Sold (COGS) ÷ Average Inventory
Average inventory is calculated using the following formula:
Average Inventory = (Beginning Inventory + Ending Inventory) ÷ 2
Example
A Moroccan company reports annual sales with a Cost of Goods Sold (COGS) of 900,000 MAD.
Its inventory was worth 120,000 MAD at the beginning of the year and 180,000 MAD at the end of the year.
The average inventory is therefore:
(120,000 MAD + 180,000 MAD) ÷ 2 = 150,000 MAD
The inventory turnover ratio is then calculated as:
900,000 MAD ÷ 150,000 MAD = 6
This means the company’s inventory was sold and replenished six times during the year.
Although this figure provides a useful indication of inventory performance, it should always be interpreted according to your industry and the type of products you manage.
How to Interpret the Results
The inventory turnover ratio is only valuable if the results are interpreted correctly.
High Inventory Turnover
A high turnover ratio generally indicates that products are selling quickly. Inventory remains in storage for a shorter period, improving cash flow and reducing inventory carrying costs.
However, an excessively high turnover may also indicate insufficient inventory levels. In this case, the business faces a greater risk of stockouts, potentially leading to lost sales and dissatisfied customers.
Low Inventory Turnover
Conversely, a low turnover ratio means products remain in storage for a long time.
This can lead to several problems, including:
- Higher storage costs
- Capital tied up in inventory
- Increased risk of obsolete inventory
- Expired or damaged products, depending on the industry
The goal is therefore not to achieve the highest possible inventory turnover, but rather to maintain a healthy balance between product availability and inventory costs.
How to Improve Inventory Turnover
Good inventory turnover depends not only on sales but also on efficient purchasing, accurate forecasting, and consistent inventory control.
The first step is to analyze the performance of every product. Some items sell quickly, while others remain in storage for months. Identifying these differences helps optimize purchasing decisions.
It is also important to review inventory levels regularly to avoid over-ordering. Monitoring sales trends improves demand forecasting and reduces purchasing errors.
The choice of inventory valuation method can also affect financial analysis. Methods such as FIFO (First In, First Out), LIFO (Last In, First Out), and Weighted Average Cost (WAC) influence the calculation of the Cost of Goods Sold depending on the company’s accounting policies.
Finally, inventory turnover should be monitored regularly—not just at the end of the financial year—to identify trends and make timely adjustments.

Why Use ERP Software to Monitor Inventory Turnover?
Calculating inventory turnover manually is manageable for businesses with only a few products. However, as the number of inventory items grows, manual calculations become increasingly time-consuming and prone to errors.
An ERP solution like Logistiqa automatically calculates key inventory management KPIs.
Inventory movements are recorded in real time, inventory valuations are updated automatically, and interactive dashboards allow managers to identify both fast-moving and slow-moving products instantly.
This enables decision-makers to identify products that tie up unnecessary capital, optimize purchasing decisions, and base inventory planning on reliable data.
For SMEs, this level of visibility helps reduce inventory costs while ensuring products remain available when customers need them.

What is a good inventory turnover ratio?
There is no universal benchmark. A good inventory turnover ratio depends on your industry, product type, and customer purchasing behavior. The most important factor is monitoring the trend over time and comparing it with your business objectives.
Can inventory turnover be calculated monthly?
Yes. Many businesses calculate inventory turnover every month to detect changes in demand early and adjust purchasing decisions before inventory problems become significant.
Why is inventory turnover important?
Inventory turnover helps evaluate the efficiency of inventory management. It reduces storage costs, improves cash flow, supports better purchasing decisions, and minimizes the risks of overstocking and stock shortages.
