Operating Margin

Why it matters

Operating margin isolates how well the agency runs as a business, which is useful when comparing periods or agencies with different tax and debt situations.

For most small agencies, operating margin and net margin are close, because interest and tax are small. As an agency takes on debt or grows, the two diverge.

How do you find the operating profit margin?

Divide operating profit by revenue and multiply by a hundred. Operating profit is revenue minus the cost of delivering the work and minus your running costs, before interest and tax. The operating profit margin ratio is what is left of every dollar once the business has actually been run, which is why it is a harder and more honest number than gross margin. For agencies it commonly lands between 10 and 20 percent, and anything above 25 usually means either an unusually efficient shop or a cost that has not been counted.

How to calculate operating margin

The calculation is one subtraction repeated three times on the same base, and the base is the part agencies get wrong. Start from net revenue, also called agency gross income, which is what you billed minus anything you only passed through: media spend, contractors, print, production travel. Then:

Operating margin = (net revenue − delivery costs − overhead) / net revenue x 100

A worked example, using the 55:25:20 split the Agency Management Institute has published since 2019 and reaffirmed in 2022. An agency bills $1,500,000 and $300,000 of that is pass-through, leaving $1,200,000 of net revenue. Delivery and loaded salaries at 55% take $660,000. Overhead at 25% takes $300,000. Operating profit is $240,000, which is 20% of net revenue. Note that the same $240,000 is only 16% of the $1,500,000 billed, and neither number is wrong.

That gap is the whole reason to use net revenue. Hold operating profit fixed at 20% of net revenue and change nothing but how much of the work is passed through: on gross billings the same business reads 20% at no pass-through, 18% at 10%, 16% at 20%, 13% at 35% and 10% at 50%. A media buyer and a design studio with identical economics would look like different businesses. Measured on net revenue they look the same, which is the point.

What is a good operating margin for an agency

There is no clean published benchmark, and treating one as though it existed is the mistake worth avoiding. The two best-sourced datasets measure different things and should not be averaged together.

What owners say. In AgencyAnalytics' 2026 benchmark survey, among 201 agency owners and leaders who gave a figure, 10% reported an operating margin under 10%, 21% reported 10 to 20%, 26% reported 21 to 30%, 19% reported 31 to 40% and 23% reported over 40%. That survey ran on Typeform between February and April 2026 and half its base leads agencies of ten people or fewer. It is self-reported and unaudited, and it does not define operating margin for respondents or say whether owner pay was deducted first, which is exactly where a small owner-led shop tends to overstate.

What a research firm measured. Promethean Research, from 119 completed responses fielded in February 2026 covering 2025 performance, puts the average digital agency at a 13% after-tax net margin, down from 14% the year before against a long-run average near 15%. Broken down by size it falls as headcount rises: 19% at studios of nine people or fewer, 12% at 10 to 24, 9% at 25 to 49 and 8% at 50 and above.

Those are not in conflict. One is a pre-tax operating figure that owners state about themselves; the other is an after-tax net figure a research firm collected. Read together they say something more useful than either alone, which is that the money is usually lost between the project and the profit rather than on the work itself.

Where agency margin actually goes

Promethean found that only 59% of agencies track margin on individual projects, and among those that do, the average project margin was 35%. Set that beside the 13% net margin from the same dataset and the shape of the problem is visible: delivery is profitable, and overhead consumes most of what delivery earns.

That is why operating margin is the more useful number to watch than gross margin. Gross margin tells you whether the work was priced correctly. Operating margin tells you whether the business around the work can be afforded, and it is the first place a hiring decision or a new office shows up.
