The Agency Margin Estimator measures how much of agency revenue remains after selected costs. It calculates gross margin from direct delivery costs and operating margin after overhead, allowing managers to separate service efficiency from the overall economics of the business.
This view is useful when pricing retainers, comparing service lines, reviewing staffing models, or testing a growth plan. Use revenue and costs from the same period and apply a consistent definition of direct cost. The calculator returns gross profit, operating profit, gross margin, and operating margin so that a healthy delivery margin is not confused with final profitability.
1. Set the revenue base
Use recognized or forecast revenue for one consistent period.
2. Define direct cost
Enter costs directly associated with delivering client work.
3. Add overhead
Include agency-wide operating expenses not assigned to specific projects.
4. Compare the two margins
Gross margin reflects delivery economics; operating margin also includes overhead.
Gross margin (%) = (Revenue − Direct costs) ÷ Revenue × 100
Operating margin (%) = (Revenue − Direct costs − Overhead) ÷ Revenue × 100
The calculation assumes all inputs use the same accounting period and currency. A zero-revenue scenario returns zero percentages to avoid an undefined division.
Operating margin shows the share of revenue remaining after both client-delivery cost and agency overhead.
Margin definitions vary, so document which labor and pass-through costs are treated as direct.
Given: Revenue of $300,000, direct costs of $165,000, and overhead of $75,000.
Calculation: Gross profit = $135,000, so gross margin = 45%. Operating profit = $60,000, so operating margin = 20%.
Result: The agency retains 20 cents of operating profit per revenue dollar under these assumptions.
Gross margin isolates service-delivery economics. Operating margin shows what remains after agency-wide overhead.
That depends on whether the agency records it gross or net. Use the same accounting treatment in both revenue and cost inputs.
The calculator reports zero margins because a percentage cannot be calculated without revenue.
Yes, provided each team uses the same cost definitions and reporting period.
Margin divides profit by revenue, while markup divides profit by cost.
