Managing inventory can feel exhausting when your cash stays tied up in stock, shelves keep filling up, and demand remains uncertain. You may be dealing with slow-moving items, rising storage costs, and constant pressure to avoid shortages without overbuying.
Research shows carrying costs usually account for between 20% and 30% of total inventory value, steadily eating into margins without obvious warning signs. When you lack a clear way to measure how fast products sell, inventory decisions often rely on assumptions rather than clear financial signals.
In this blog, we’ll explore what inventory turnover means, how the inventory turnover ratio works, how to calculate it correctly, and how to interpret results. We’ll also cover practical examples, deadstock risks, common limitations, and realistic ways to improve inventory turnover.
Learn how HAL ERP helps small and medium-sized businesses in Saudi Arabia gain better inventory visibility and control through automated, data-driven systems.
Inventory turnover measures how often you sell and replace your stock within a specific period, usually monthly or annually. It shows how quickly your products move from storage to customers, helping you understand whether inventory levels match actual demand.
Understanding inventory turnover sets the foundation for deeper analysis, especially when evaluating whether your turnover rate signals balance or potential risk.
Inventory turnover can become problematic when it swings too far in either direction, creating different operational and financial pressures. A very low inventory turnover often points to weak demand forecasting, excess purchasing, or products losing relevance in the market.
On the other hand, extremely high inventory turnover may signal frequent stock shortages, rushed purchasing, or missed sales opportunities. When you carry too little inventory, customers may face delays, and your teams may struggle to keep up with replenishment needs.

To move from concept to measurement, you need a ratio that translates inventory movement into a clear financial indicator.
The inventory turnover ratio is a financial measure that shows how many times you sell and replace inventory during a specific period. You track this ratio to assess whether purchasing levels match sales activity and whether inventory investment supports actual customer demand.
For many Saudi businesses, a low ratio signals cash tied up in unsold goods, while a high ratio points to faster stock movement. Holding inventory longer increases storage, insurance, and obsolescence costs, which steadily reduce available working capital.
To understand this ratio clearly, it helps to review the formula, how it works, standard benchmarks, and its practical limits.
The inventory turnover ratio uses two cost-based figures from your financial statements.
Standard inventory turnover ratio formula:
Inventory Turnover Ratio = Cost of Goods Sold ÷ Average Inventory
Each component serves a clear purpose.
Average inventory is calculated as:
Average Inventory = (Beginning Inventory + Ending Inventory) ÷ 2
Some businesses use sales instead of COGS, though this often inflates results because sales include profit markup.
The logic behind the inventory turnover ratio focuses on the balance between sales activity and inventory investment. Inventory represents cash tied up in goods, waiting to be sold and converted back into liquidity.
Here is what the ratio reflects in practice:
This relationship helps you spot whether inventory supports growth or quietly strains cash flow.
A good inventory turnover ratio depends heavily on your industry, product type, and margin structure. High-volume, low-margin businesses usually record higher turnover than low-volume, premium product sellers.
Here are general reference points to guide interpretation:
The goal is consistency within your industry rather than chasing a universal benchmark.
While useful, the inventory turnover ratio does not tell the full inventory story on its own. It can mislead when viewed without context, seasonality, or supporting metrics.
Here are common limitations you should keep in mind:
Because of these factors, the ratio works best when reviewed alongside other inventory and financial measures.

Calculating the inventory turnover ratio helps you understand how frequently your inventory converts into sales within a defined accounting period. This process relies on financial statements you already use and directly connects inventory levels with sales activity.
Here are the steps involved in the calculation, explained clearly:
Choose the accounting period:
Select one financial year to keep the calculation consistent and make year-to-year comparison easier.
Identify Cost of Goods Sold:
Cost of Goods Sold reflects the direct cost of purchasing or producing goods sold during the year. This value appears on the income statement and excludes indirect costs like rent or marketing. In this example, the business reports an annual Cost of Goods Sold of SAR 500,000.
Determine beginning inventory:
Beginning inventory represents the value of stock available at the start of the year. This figure is usually taken from the previous year’s closing balance. In this example, beginning inventory equals SAR 40,000.
Determine ending inventory:
Ending inventory is the value of stock remaining at the end of the same year. It shows how much inventory remains unsold. In this example, ending inventory equals SAR 60,000.
Calculate average inventory:
Add beginning inventory and ending inventory, then divide by two to reduce the effect of short-term fluctuations.
Calculation: (40,000 + 60,000) ÷ 2 = 50,000 SAR
Calculate the inventory turnover ratio:
Divide the Cost of Goods Sold by the average inventory to find how often inventory was sold and replaced.
Calculation: 500,000 ÷ 50,000 = 10
Interpret the result:
Your inventory turnover ratio is 10, meaning the business sold and replaced its entire inventory ten times during the year. Roughly speaking, this means the warehouse is cleared out about every 1.2 months on average.

Once you can calculate inventory turnover, you can use the result to spot slow-moving items and growing dead stock.
Inventory turnover plays a critical role when you sell products with limited shelf life or seasonal demand, such as groceries, fashion, or vehicles. When stock sits too long, changing trends or expiration dates can turn valuable goods into items that no longer generate revenue.
Dead stock refers to inventory that remains unsold for extended periods and no longer meets customer demand. A consistently low inventory turnover ratio often signals this issue, since low sales reduce recorded cost of goods sold, leaving excess stock trapped in storage.
To gain a fuller view of inventory health, you should review turnover alongside other commonly used inventory ratios.
Inventory turnover provides helpful insight, though it becomes far more meaningful when reviewed alongside other inventory-focused financial ratios. These supporting measures help you assess stock aging, sales balance, and profitability using different financial perspectives.
To build a clearer view of inventory performance, here are commonly tracked inventory ratios with their definitions and formulas:
Once these ratios highlight problem areas, the next focus becomes practical actions that help improve inventory turnover.

Improving inventory turnover starts with understanding why products stay in storage longer than expected and where purchasing decisions fall out of sync with demand. Minor adjustments in planning, ordering, and review cycles can gradually reduce excess stock while keeping customers supplied.
Here are practical actions businesses often take to improve inventory turnover over time:
As inventory volumes grow, technology-based systems can support better visibility and control beyond manual processes.

1. What increases inventory turnover?
Inventory turnover often increases when purchasing quantities align more closely with actual sales patterns rather than projections. Better demand visibility, regular review of slow-moving items, and timely price adjustments also help products move faster through inventory.
2. What is an acceptable inventory turnover ratio?
An acceptable inventory turnover ratio depends on factors like industry type, product shelf life, and profit margins. Comparing your ratio against similar businesses in the same sector usually provides more useful insight than aiming for a fixed number.
3. How often should inventory turnover be reviewed?
Inventory turnover should be reviewed monthly or quarterly to catch changes in sales behaviour and stock buildup early. Regular review helps you adjust purchasing decisions before excess inventory affects cash flow.
4. Does inventory turnover affect business valuation?
Inventory turnover can influence how lenders and investors view your business because it reflects stock control and cash usage. Consistent turnover often signals stable demand and disciplined purchasing practices.
5. Can inventory turnover vary within the same business?
Inventory turnover often differs across product categories due to pricing, demand cycles, or regulatory constraints. Tracking turnover by category helps you make better decisions than relying on a single company-wide figure.
