Efficiency ratios are metrics that measure how well a company uses its resources to generate income and profit. They reflect the operational performance and management quality of a business, as well as its competitive advantage in the industry. Efficiency ratios can help investors, creditors, and managers evaluate the financial health and growth potential of a company.

To calculate efficiency ratios, you need to obtain the relevant financial data from the company’s income statement and balance sheet, such as net sales, cost of goods sold, average total assets, average inventory, average accounts receivable, and average accounts payable. Then, you can use the following formulas to compute different types of efficiency ratios:

• Asset turnover ratio = Net sales / Average total assets
• Inventory turnover ratio = Cost of goods sold / Average inventory
• Accounts receivable turnover ratio = Net credit sales / Average accounts receivable
• Accounts payable turnover ratio = Cost of goods sold / Average accounts payable

To interpret efficiency ratios, you need to compare them with the industry averages, the company’s historical performance, or the company’s competitors. Generally, a higher efficiency ratio indicates that a company is using its resources more effectively and generating more income per unit of resource. However, a very high efficiency ratio may also indicate that a company is underinvesting in its assets or inventory, which may hurt its long-term growth.

Here are some examples of how to calculate and interpret efficiency ratios for two hypothetical companies, A and B, in the same industry:

A	10,000,000	6,000,000	5,000,000	1,000,000	500,000	600,000
B	8,000,000	4,000,000	4,000,000	800,000	400,000	500,000

Company	Asset turnover ratio	Inventory turnover ratio	Accounts receivable turnover ratio	Accounts payable turnover ratio
A	2	6	20	10
B	2	5	20	8

• Both companies have the same asset turnover ratio of 2, which means they generate $2 of sales for every $1 of asset. This is a good sign of asset efficiency, but it does not tell us much about their relative performance.
• Company A has a higher inventory turnover ratio of 6, which means it sells its inventory six times a year, while Company B sells its inventory five times a year. This suggests that Company A has lower inventory holding costs and higher demand for its products than Company B.
• Both companies have the same accounts receivable turnover ratio of 20, which means they collect their credit sales 20 times a year, or every 18 days on average. This indicates that both companies have efficient and timely collection policies and low credit risk.
• Company A has a higher accounts payable turnover ratio of 10, which means it pays its suppliers 10 times a year, or every 36 days on average, while Company B pays its suppliers eight times a year, or every 45 days on average. This implies that Company A has lower trade credit cost and better supplier relations than Company B, but it may also have lower cash flow and solvency than Company B.

Based on these examples, we can conclude that Company A is more efficient than Company B in terms of inventory management and payables payment, but they are equally efficient in terms of asset utilization and receivables collection. However, we also need to consider other factors, such as the industry average, the quality and value of the assets, inventory, receivables, and payables, and the external market conditions, to get a more comprehensive and accurate assessment of the companies’ efficiency and profitability.
