Split sales into the operating profit you keep and the operating costs you spend.

The operating profit margin indicates what portion of the revenue a company generates as its operating income. It is the profit that results from a company's operations and is expressed as a percentage of sales before interest and taxes are deducted.

If you enter two of the three values (operating profit, net sales or operating margin), the tool will calculate the remaining value. If you know the profit and sales, you get the margin. If you know a target margin and sales, you can find out what profit is required. If you know a target margin and desired profit, you can find out what sales are needed to achieve that goal.

Formula for calculating sales operating profit margin:

The operating profit margin is calculated by dividing the operating income by net sales and expressing the result as a percentage.

\text{Return on Sales} = \left(\frac{\text{Operating Profit}}{\text{Net Sales}}\right) \times 100

The same relationship rearranges to solve for either of the other two figures.

\text{Operating Profit} = \frac{\text{ROS} \times \text{Net Sales}}{100}

\text{Net Sales} = \frac{\text{Operating Profit}}{\text{ROS}} \times 100

It becomes more understandable when you look at concrete examples. A business has a monthly net turnover of $200,000 and the cost of producing the goods is $170,000, so the operating profit is $30,000. If you divide 30,000 by 200,000, it results in a return on sales of 15 percent. In other words: for every sale of $100, $15 goes to the operating profit.

Term	Where it comes from	Example
Operating profit (EBIT)	Sales minus COGS minus operating expenses	30,000
Net sales	Gross sales minus returns, discounts, allowances	200,000
Return on sales	Operating profit / net sales x 100	15%

Here's how to use this calculator:

Enter revenue and operating profit for the same period, then select the appropriate scale (thousands, millions or billions).
Check the sales operating profit margin. If you want to work backwards, enter a target rate and either the profit or the turnover to automatically calculate the missing value.
Activate "Calculate operating profit based on income statement" and enter the material costs and operating expenses to see the gross profit and operating profit step by step.
Turn on Compare to Net Income to understand how interest and taxes can cause net income to fall below the operating profit margin.
Turn on Industry Comparison to compare your results with typical values for your industry.

Sales-Operating Profit Margin and Net Profit Margin:

These are two of the most commonly misunderstood metrics. Both divide profit by sales, but there is a difference in the numerator of each ratio.

The revenue operating profit takes into account the operating result, i.e. the earnings before interest and taxes (EBIT) and measures only the performance of the core business.
The net profit margin uses net income, which is the bottom line after interest and taxes are paid.
The difference between the two values comes directly from interest and tax burdens. Companies with high debt or a high tax burden can have healthy sales operating margins but their net profit margin can be significantly lower.

Because operating profit does not take into account the company's financing choices or tax burden, ROS is a good way to compare the performance of two companies with different levels of debt.

Return on sales and gross profit margin

Both the gross profit margin and return on sales compare a particular profit to net sales, but they take into account different costs in calculating that profit.

The gross profit margin only takes into account the direct costs of producing the goods sold. The return on sales also includes operating expenses such as salaries, rent and marketing costs. Therefore a high cost to income ratio can result in low returns on sales even if the gross profit margin is high. Comparing both values allows you to pinpoint which costs are eating away at profits.

What is a good return on sales?

Most companies are satisfied with a return on sales of between 5 percent and 10 percent. The fact that it is positive alone is a good sign. In most industries more than 10 percent is considered to be good, while over 20 percent is exceptionally high.

However, the background conditions are extremely important. Food chains are based on their sales volume and therefore deliberately keep operating profit margins low. Software companies, however, should have significantly higher values. The entire industry is subject to economic cycles. In normal years, car dealerships' operating profits are around 7 percent, while in air freight they're at minus 42 percent. This figure fell to that level in 2020 and then recovered again. Don't compare on the basis of absolute values but always with comparable companies from the same industry and check the development over the last two to three years.

Measuring efficiency - When return on sales falls it is often the first sign that costs are rising faster than sales.
Comparison with competitors - Comparing the return on sales to that of competitors shows how much leeway a company has in lowering prices and still be profitable.
Provide information to lenders - Lenders look at the return on sales as a measure of whether core business is generating stable profits and the company can pay back its debts.

How to improve your return on sales:

There is almost never a single aspect to focus on. It usually requires a series of small adjustments in order to get more operating profit out of each individual sale.

Reduce operating costs without reducing production - automate repetitive tasks, disable unused software and give up office space that is no longer fully used.
Reduce material costs - renegotiate with suppliers when renewing contracts, order in bulk to get volume discounts and change materials if it doesn't affect quality.
Raise the price within a range that is acceptable to the market and observe the effect on sales volume. If there is little change in sales volume, then a small increase in price can significantly improve profit margin.
We are changing our product mix to offer products with higher profit margins and a slight decrease in sales is acceptable. Companies with lower volumes but higher profits are generally healthier.
These metrics are reviewed quarterly. If negative trends are detected early enough, they can be corrected with small adjustments. However, if discovered too late, a more extensive reorganization will be required.

Limitations of sales-profit ratio

The return on sales ratio is useful for comparing companies' situations because it intentionally excludes operating side effects. However, it does not reflect the whole picture. Interest and taxes are not taken into account, and operating profit still includes non-cash expenses such as depreciation, so it does not match cash flow.

When comparing across industries, analysts often switch to the EBITDA margin. The EBITDA margin adds back depreciation and amortization, which allows for a fairer comparison between capital-intensive manufacturers and low-capital companies. The return on sales should be used in combination with other metrics and not viewed in isolation.

Frequently asked questions

What is a good return on sales?

Most companies are happy with a return on sales of 5 percent to 10 percent, and any positive number is a good sign. In most industries, a return on sales above 10 percent is considered healthy, while anything over 20 percent would be considered unusually high. However, this varies widely by industry. Grocery chains can have low returns on sales because of the volume they sell at, whereas software companies should have much higher numbers. Compare yourself to similar companies in your industry and don't judge on a single number - look at trends over two or three years.

What is the difference between return on sales and net profit margin?

Both divide profit by net sales but the difference is in what type of profit they use. The return on sales uses operating income or EBIT (earnings before interest and taxes). The net profit margin uses net income, which is the bottom line after interest and taxes are paid. The difference between them is that interest and taxes are subtracted from the earnings to get the net profit margin. So a company with high debt or a very high tax burden can have a healthy return on sales while the net profit margin may be much lower.

What is the difference between the sales operating profit ratio and the net operating profit ratio?

The two terms are often used synonymously and will usually result in the same outcome. The only slight difference is in the numerator. The sales operating margin is typically calculated using EBIT (earnings before interest and taxes), which is a non-GAAP measure. The pure operating margin, on the other hand, uses operating income, which is a GAAP number found on an income statement. As most companies treat EBIT and operating income as equivalent, both ratios will be in agreement.

Can the sales operating profit ratio be negative?

Yes it is possible. A negative revenue operating profit ratio means that the core business expenses were higher than the income in a particular period resulting in an operating loss. This often happens during the early stages of a company when investments need to be made before revenues are generated. It can also happen during economic downturns. The airline industry has had a revenue operating profit ratio of around minus 42 percent and reached this level in 2020. A single period with a negative value is usually not critical but if the revenue operating profit ratio is consistently negative, then costs and pricing need to be urgently reviewed.

How can a company improve its revenue operating profit ratio?

There are two main areas to focus on: costs and revenue. To increase the sales operating profit ratio, companies can try to reduce operational expenses without affecting production, renegotiate prices with suppliers to lower material costs, raise prices within market conditions while keeping an eye on sales volumes, and reorient product portfolio towards more profitable products. Small adjustments combined can have a big impact. A slight price hike for high-volume selling items can significantly boost operating profit. If this value is checked quarterly, negative trends can often be corrected with small adjustments without requiring a major restructuring.
