Inventory turnover is often used in business, but what does it mean? Inventory turnover measures how quickly a company sells and replaces its inventory over time.

It’s a key metric for gauging a company’s inventory management efficiency and overall business performance.

Definition of Inventory Turnover

Here’s the deal: inventory turnover is the number of times an inventory sold and replaced within a specific timeframe, usually a year.

It’s calculated by dividing your cost of goods sold (COGS) by your average inventory value for that period. This ratio reveals how effectively you manage your stock and generate sales from your inventory investment.

Importance of Inventory Turnover

Why should you care about knowing how to calculate inventory turnover? Because it’s a powerful indicator of your company’s financial health and operational efficiency.

A high turnover rate generally means selling products quickly and effectively, minimizing holding costs, and reducing the risk of obsolescence.

Conversely, a low turnover rate may signal weak sales, excess inventory, or inefficient purchasing practices.

Factors Affecting Inventory Turnover

It’s important to understand that inventory turnover isn’t a one-size-fits-all metric. It varies significantly across industries and is influenced by product type, demand patterns, and supply chain dynamics.

For example, fast-moving consumer goods (FMCG) companies typically have higher turnover rates due to the perishable nature of their products (also referred to as time-sensitive goods).

In contrast, luxury car dealerships may have lower ratios given the high value and slower inventory sales. Other factors impacting your inventory turnover include: 

  • Seasonality and market trends 
  • Supplier lead times and reliability 
  • Inventory management strategies (e.g., just-in-time vs. bulk ordering) 
  • Product life cycles and obsolescence risk. 

The key is to benchmark your turnover ratio against industry standards and monitor it over time to identify trends and areas for improvement.

Optimizing your inventory turnover can free up working capital, improve cash flow, and boost your bottom line.

Let’s dive into the nitty-gritty of learning how to calculate inventory turnover. The formula is pretty straightforward, but there are a few nuances to remember.

Inventory Turnover Formula

The inventory turnover formula is Inventory Turnover = Cost of Goods Sold (COGS) / Average Inventory.

Where: – COGS = Direct costs of producing and selling your products – Average Inventory = (Beginning Inventory + Ending Inventory) / 2

Calculating Cost of Goods Sold

To calculate your COGS, add all the direct costs of making and selling your products during the specific period.

This typically includes raw materials and supplies, direct labor costs, manufacturing overhead expenses, and freight and shipping costs.

You can find your COGS on your income statement or profit and loss (P&L) report.

Determining Average Inventory

Next, calculate your average inventory value for the same period. This is done by adding your beginning inventory balance (the value of your inventory at the start of the period) to your ending inventory balance (the value at the end of the period) and dividing the sum by two.

An average inventory value helps smooth out seasonal fluctuations or one-time events that may skew your high turnover ratios.

Example Turnover Calculation

Let’s say your company had the following financials for the past year: – COGS: $500,000 – Beginning Inventory: $100,000 – Ending Inventory: $150,000. To calculate your inventory turnover ratio: 

1. Average Inventory = ($100,000 + $150,000) / 2 = $125,000 

2. Inventory Turnover = $500,000 / $125,000 = 4 

This means your company sells and replaces its inventory four times yearly. Whether this is good or bad depends on your industry benchmarks and historical performance. That is how to calculate inventory turnover.

  • Reduced holding costs and obsolescence risk 
  • Improved cash flow and liquidity.

  • Weak demand or poor product-market fit 
  • Overstocking or inefficient purchasing practices 
  • Increased carrying costs and tied-up capital 
  • Higher risk of obsolescence or spoilage

Of course, these are broad generalizations, and there may be valid reasons for a low turnover ratio, such as intentional stockpiling ahead of a busy season or anticipated supply chain disruptions.

Industry Benchmarks

To understand the inventory turnover ratio, compare it to industry benchmarks. These can vary significantly based on product type, business model, and market dynamics.

Revenue per employee increased from $409,596 to $573,999, and net income per employee rose from $44,170 to $54,791, indicating enhanced efficiency and profitability.

However, the receivable turnover ratio declined from 4.45 in Q4 2023 to 4.04 in Q1 2024, suggesting inadequate inventory differences.

The inventory turnover ratio based on sales improved significantly from 10.44 to 13.21, showing better inventory management, while the ratio based on the cost of sales fluctuated, ending at 9.07.

The asset turnover ratio also saw a slight improvement, from 0.25 to 0.27, reflecting better utilization of assets.
