## What Are Profitability Ratios?

Profitability ratios compare a company’s earnings to other financial metrics such as its revenue, operating income, or assets.

In general, profitability ratios show how well a company generates profits from its business activities.

There are many different types of profitability ratios, but some of the most common include the gross margin ratio, operating margin ratio, and net profit margin ratio.

## Most Common Profitability Ratios

### Gross Margin Ratio

The gross margin ratio is one of the most commonly used profitability ratios. It measures a company’s gross profit as a percentage of its total revenue.

To calculate the gross margin ratio, divide a company’s gross profit by its total revenue.

For example, if a company has a gross profit of \$5 million and total revenue of \$20 million, its gross margin ratio would be 25%.

### Operating Margin Ratio

The operating margin ratio is another common profitability ratio. It measures a company’s operating income as a percentage of its total revenue.

To calculate the operating margin ratio, divide a company’s operating income by its total revenue.

For example, if a company has an operating income of \$3 million and total revenue of \$20 million, its operating margin ratio would be 15%.

### Net Profit Margin Ratio

The net profit margin ratio is the last of the three most common profitability ratios. It measures a company’s net income as a percentage of its total revenue.

To calculate the net profit margin ratio, divide a company’s net income by its total revenue.

So, if a company has a net income of \$2 million and total revenue of \$20 million, its net profit margin ratio would be 10%.

## Why Are Profitability Ratios Important?

Profitability ratios are important because they show how well a company is generating profits from its business activities.

They can be used to compare similar companies in the same industry, or to compare a company to its own historical performance.

Profitability ratios can also be used to assess a company’s financial health and identify potential red flags.

For example, if a company’s gross margin ratio is declining, it may be struggling to generate profits.

Finally, profitability ratios can be used in valuation models to help estimate a company’s fair value.

## How to Use Profitability Ratios in Trading

Profitability ratios can be used in a number of different ways in trading.

### Screening

First, they can be used to screen for companies that are generating healthy profits.

For example, you might screen for companies with a gross margin ratio above 30%.

### Comparison

Profitability ratios can be used to compare similar companies in the same industry.

### Use in valuation

Profitability ratios can be used in valuation models to estimate a company’s fair value.

For example, you might use the net profit margin ratio to estimate how much earnings power a company has.

### Markers of financial health

Also, profitability ratios can be used to assess a company’s financial health.

For instance, a company with a declining gross margin ratio may be struggling to generate profits.
