How is net margin calculated?
Start with fee revenue, which excludes pass-through costs such as media spend. Subtract direct labor cost to get gross profit. Then subtract overhead: rent, software, sales and marketing, finance and admin, leadership salaries, insurance, professional fees and depreciation. Divide the result by fee revenue and multiply by 100.
Owner compensation is the number most often fudged. If the founders take a market salary for the roles they perform, net margin is honest. If they take distributions instead of salary, add a market salary back into overhead before computing the margin, or the figure overstates how healthy the business is.
What is a good net margin for a marketing agency?
A net margin of 15 to 25% is healthy for an independent marketing agency. Below 10% the agency has no buffer for a lost client or a slow quarter. Above 30% is possible for specialized or productized agencies but is unusual for full-service shops with custom work.
Net margin is the product of two numbers: gross margin and overhead ratio. A 55% gross margin with overhead at 35% of revenue produces 20% net. A 50% gross margin with 40% overhead produces 10%. Small changes in either number move the bottom line a lot, which is why both need tracking.
- Gross margin 50 to 60%, overhead 30 to 40%: net margin 15 to 25%, healthy
- Gross margin 45%, overhead 38%: net margin 7%, fragile
- Gross margin 60%, overhead 30%: net margin 30%, strong, usually a specialist
What drives net margin up or down?
Delivery is the largest lever. Unbilled work, scope creep and low utilization all reduce gross margin, and every point lost there comes straight out of net. An agency that fixes its realization rate from 80% to 90% on the same revenue typically adds 5 or more points of net margin.
Overhead creep is the second lever. Headcount added in sales, ops and management ahead of revenue growth, plus software subscriptions that accumulate, push the overhead ratio above 40%. The third lever is pricing: a 10% fee increase on a 55% gross margin book of business adds roughly 9 points to net margin if costs stay flat.
How should net margin be tracked?
Track it monthly on an accrual basis, with retainer revenue recognized over the service period rather than when invoices are paid. Cash-basis figures lurch with billing cycles and hide the trend. Compare trailing three months against the same period a year earlier.
Client-level net margin is useful but requires allocating overhead, which is always somewhat arbitrary. Most agencies allocate overhead in proportion to direct labor hours and treat the result as directional. Client-level gross margin, which needs no allocation, is the more reliable number for account decisions.
Worked example
A 12-person agency earns $2,400,000 in annual fee revenue, about $200,000 per head, after removing $600,000 of media spend billed at cost. Direct labor for nine delivery staff at 173.3 hours per month costs $1,080,000, so gross profit is $1,320,000 and gross margin is 55%. Overhead, including two founders on market salaries, an operations lead, rent, software and sales costs, totals $840,000 or 35% of revenue. Net profit = $2,400,000 less $1,080,000 less $840,000 = $480,000. Net margin = $480,000 ÷ $2,400,000 × 100 = 20%. If the founders instead took no salary and the $300,000 was left out of overhead, net margin would appear to be 32.5%, which is misleading.
Questions
Should net margin be calculated on gross billings or fee revenue?
Fee revenue. Gross billings include media spend and other pass-through costs that the agency collects and pays out without earning, and including them shrinks the margin percentage to a number that means nothing. An agency with $2.4 million in fees and $600,000 in media should report margin on the $2.4 million.
What is the difference between net margin and EBITDA margin?
EBITDA margin adds back interest, taxes, depreciation and amortization, so it is always higher than net margin. Buyers and lenders usually quote EBITDA margin for agencies. For running the business month to month, net margin after owner salaries is the more honest number.
Why is my gross margin healthy but my net margin low?
Overhead is too high for the revenue. A 55% gross margin with 45% overhead leaves 10%. Common causes are non-delivery headcount hired ahead of growth, founders who are no longer billable but still counted as delivery, and software and office costs that grew faster than fees.
