Operating margin: follow SEK 100,000 from revenue to operating profit

Move through the expenses one step at a time

The fictional company has net revenue of SEK 100,000. Cost of goods sold is SEK 60,000, leaving gross profit of SEK 40,000. The model then subtracts SEK 20,000 of other operating expenses and SEK 5,000 of depreciation. Operating profit is 40,000 − 20,000 − 5,000 = SEK 15,000.

Our operating profit already includes the depreciation expense. It is therefore not a measure before depreciation. Interest and tax come after operating profit in this particular ladder. All amounts are fictional and the expense rows are separate; the same depreciation must not be deducted again if it were already included in another expense row.

If the table does not fit, scroll it sideways.

15,000 out of 100,000 gives 15%

Operating margin is 15,000 / 100,000 × 100 = 15%. In this model SEK 15 of operating profit remains per SEK 100 of sales. Gross margin at an earlier step is instead 40,000 / 100,000 = 40%. The difference comes from which expenses have been included.

Use the same period for numerator and denominator. Dividing a quarter’s operating profit by a whole year’s revenue does not give the quarterly operating margin. Also check the unit: if profit is stated in thousands of kronor, revenue must use the same scale before you divide. A percentage can otherwise look plausible while relying on mismatched inputs.

Net margin comes at a later step

We now add an interest expense of SEK 3,000 and a fictional tax expense of SEK 2,400. The model produces profit before tax of SEK 12,000 and net profit of SEK 9,600. Net margin is therefore 9,600 / 100,000 = 9.6%. The tax amount is a given input, rather than a current tax rule or a recommended tax rate.

An operating margin of 15% and a net margin of 9.6% are both correct for this example. They answer different questions. With only operating profit and revenue, you cannot assume final net earnings; financing and tax can still change the answer. More profit in money also does not automatically mean a larger margin.

If the table does not fit, scroll it sideways.

Check the company’s definition before comparing

Actual reports may also present adjusted profit measures and their own explanations of one-off items. Read the reconciliation to reported amounts. Our simple operating profit before interest and tax describes these stated items, rather than guaranteeing that every alternative company measure with a similar abbreviation is identical.

Record the company, period, revenue line, profit measure and any adjustments. Then compare inputs that really address the same question.

This earnings ladder is a manual exercise and says nothing about automatic margin analysis in the app.
