Planning comparison only. Check estimates, omitted costs, timing, and constraints before making an operating decision.

What it calculates

Agency Margin Calculator uses monthly revenue, delivery hours, blended cost per hour, pass-through costs, and monthly overhead to estimate gross margin, operating margin, labor cost, delivery cost, and operating profit.

Formula

Agency margin formula

Gross margin = (revenue - labor cost - pass-through costs) / revenue x 100

Operating margin subtracts overhead after delivery cost. Use loaded labor cost for a cleaner estimate.

How to use

Steps

  1. Enter monthly revenue for the agency, team, or client group.
  2. Enter delivery hours and blended labor cost per hour.
  3. Add pass-through costs and overhead allocation.
  4. Review gross margin, operating margin, labor cost, and delivery cost.

Calculator use

Best for

  • Checking whether current client revenue covers delivery labor, pass-through costs, and agency overhead in the same month.
  • Comparing a proposed hire, contractor mix, or rate increase against gross and operating margin before changing the staffing plan.
  • Separating delivery economics from overhead so an apparently profitable account does not hide an agency-level loss.
  • Running a downside case for lower utilization, higher blended labor cost, or unexpected client expenses before approving scope.

Before relying on it

Check first

  • Using payroll wage instead of a loaded hourly cost that includes employer taxes, benefits, software, and non-billable time.
  • Counting pass-through media, production, or freelancer spend as margin-bearing revenue without including the matching cost.
  • Leaving owner delivery time or unbilled revisions out of delivery hours and overstating operating profit.
  • Comparing monthly margins without accounting for retainers billed in advance, delayed vendor invoices, or uneven project timing.

Details

What to know before using the result

Pass-through treatmentKeep reporting consistent

Pass-through ad spend, media, contractors, and outside vendors can distort agency margin if one report counts them as revenue and another excludes them.

Gross vs operating marginDelivery cost vs overhead

Gross margin subtracts labor and pass-through delivery cost. Operating margin also subtracts monthly overhead, so it is usually a better management view.

Blended labor costLoaded average cost

Use a loaded blended cost per hour that includes payroll burden, contractor cost, management time, and delivery overhead when possible.

Next decisionClient, retainer, margin, terms, or cash flow

After checking agency margin, review client profitability, retainer pricing, profit margin, payment terms, and small-business cash flow before changing staffing or pricing.

Benchmarks

How to read the result

Under 30%: Tight.

A broad heuristic that may leave little room for sales, admin, management, and profit.

30% - 50%: Workable.

Often a more stable range if scope, staffing, and overhead are controlled.

50%+: Strong.

Can indicate efficient delivery, premium pricing, or under-counted labor cost.

FAQ

Common questions

What is agency margin?

Agency margin is the percentage of revenue left after delivery costs such as labor and pass-through expenses.

Should pass-through ad spend count as revenue?

It depends on how you report revenue. Keep pass-through costs consistent so the margin comparison is not distorted.

What is blended cost per hour?

Blended cost is the average loaded hourly cost for the people delivering the work, including payroll burden when possible.

What is the difference between gross margin and operating margin?

Gross margin subtracts labor and pass-through delivery costs from revenue. Operating margin subtracts overhead too, so it shows more of the agency's operating profitability.
