Marketing Agency Rate Calculator
Small agencies typically sell monthly retainers, but the retainer should still be built from a real hourly rate, team overhead and realistic monthly billable hours.
Agency-specific cost considerations
- "Hours/week" here represents combined team billable capacity, not one person — adjust for however many billable staff you have.
- Software/tool stack costs (ads platforms, analytics, project management) scale with client count and should be reflected in overhead.
- Scope creep on "a few extra hours" per client is the most common way agency retainers become unprofitable — track actual hours per client regularly.
Worked example
$180,000 target compensation, $60,000 overhead, 48 weeks, 40 combined hrs/week, 65% utilization, 10% reserve, 15% margin, 15 hrs/month/client:
- Billable hours: 48 × 40 × 0.65 = 1,248 hours/year (104/month)
- Recommended rate: $240,000 ÷ (1 − 0.25) ÷ 1,248 ≈ $256.41/hour
- Monthly retainer: 15 × $256.41 ≈ $3,846
- Max clients: 104 ÷ 15 ≈ 6.9 clients at this scope

Frequently asked questions
How do I price a retainer if scope varies month to month?
Price for an average expected monthly hour commitment, and define an explicit overage rate for hours beyond that in the contract.
What is a healthy utilization rate for an agency?
Small agencies with dedicated account/admin roles often run 55-70% billable utilization for delivery staff.
Protect agency capacity and gross margin
An agency rate must fund delivery and the people who sell, manage and improve the work. Capacity planning is therefore as important as payroll: unused or unbillable team time changes the rate every client needs to support.
Use the rate in packaging
- Estimate strategy, account management, reporting and internal QA alongside production.
- Set retainer scope with deliverables, cadence and a clear process for additional requests.
- Review gross margin by client so one demanding account does not consume the portfolio profit.
Inputs that move quickly
- Contractors, media tools and reporting platforms can change cost by service line.
- Rush work and fragmented approvals reduce usable team capacity.
- Ad spend is client media budget, not agency revenue, unless the contract explicitly says otherwise.
