# Operating Ratios

Operating ratios are a class of ratios that are meant to analyze how well a company is using their assets. Specifically, these ratios show how well a company utilizes its assets to create revenue. Like many of the ratios that are used in financial analysis, operating ratios are complex ratios. Some use simple measures in their numerators and denominators, such as COGS (Cost of Goods Sold) and revenue, but many incorporate other ratios into the calculation. Therefore, it is crucial to have a firm grasp on the most basic ratios, such as working capital. Like all ratios, these are only meaningful when compared across time, and to the industry norm.

## Sample Financial Statements

We will use the following sample financial statements as the example for all of our ratios.

## Common Operating Ratios

### Inventory Turnover

The inventory turnover looks at how long a firm has inventory. The formula is:

For this firm, the inventory turnover would be 4x. This means that the firm completely sells its inventory about 4 times during the period. Some industries, like grocery stores, have a very high turnover, while others, like a Bentley dealership, will have very low turnover ratios. Therefore, it is crucial to understand what industry is being looked at, and what the average for that industry is. Comparing the ratios over time to see how it changes will also reveal any trends.

### Days of Inventory on Hand (DOH)

Inventory turnover can be taken one step further to see how many times a firm depletes its inventory over the year. The equation is:

In most cases, the number of days will be 365. In this case, 365/4 is ~91. This means that every 91 days, inventory is completely depleted. A high turnover ratio, and thus a low DOH ratio, may mean that the firm isn’t keeping enough inventory on hand. A low turnover ratio, and a high DOH ratio, may mean the firm is having issues selling the inventory. These ratios often point toward other problems in the firm, and are used as a starting place. If turnover is low, one may want to look into the company further to find out why.

### Receivables Turnover

The receivables turnover ratio shows how many times in a given period cash is collected from buyers. The formula is:

This firm has a receivables turnover of 2x, which means that is collects from its customers twice in a period. A number that is this low may indicate that the company’s credit policies are too relaxed, or that the firm lacks credit efficiency. On the other end of the spectrum, a high turnover can mean that the company has either a very efficient credit policy, or is very strict with its policy and may be losing customers to competitors with more relaxed policies.

### Days of Sales Outstanding (DOS)

As with DOH, days of sales outstanding allows an analyst to determine how many days a year sales are outstanding for a given firm. The ratio is calculated as:

The DOS for this firm is 182.5 days, which means the company goes 182.5 days without collecting from its customers. Again, it is important to compare to the industry average, because certain ratios that may seem abnormal are actually quite normal for a given industry.

### Payables Turnover

The payables turnover ratio describes how quickly a firm pays its vendors. It can be calculated as:
