Client Concentration Risk
No client should exceed 20% of revenue. High concentration makes revenue volatile and reduces acquisition valuation. Diversification across 10+ clients de-risks the business.

Quick Reference
A healthy marketing agency should target $150K+ revenue per employee, 20-30% profit margins, and under 5% monthly client churn. The average B2B marketing agency has 65% billable utilization and loses 15-25% of potential revenue to capacity gaps. Top agencies achieve 75%+ utilization and $200K+ revenue per employee.
The Scientific Model
The Scientific Model
Agency Revenue Projection Model
Formula
Monthly recurring revenue combines retainer income, amortized project revenue, and upsell revenue. Growth projection factors in net new clients (new clients minus churn).
Why this approach: Retainers provide predictable MRR; projects create revenue volatility. Optimal mix is 70% retainer / 30% project. Agencies over-indexed on projects (>50%) face cash flow challenges and growth instability.
People Also Ask
People Also Ask
- What is a good profit margin for a marketing agency?
- Healthy agency profit margins are 20-30%. Below 15% indicates pricing or efficiency issues. Above 30% often means under-investment in growth. Team costs should be 50-60% of revenue; overhead 15-20%. Top agencies achieve 25% net profit after owner compensation.
- How do I calculate revenue per employee for my agency?
- Revenue Per Employee = Annual Revenue ÷ Full-Time Employees. B2B agency benchmarks: $100K = struggling, $150K = healthy, $200K+ = excellent. Include all employees (not just billable). Agencies under $120K/employee typically have pricing or utilization problems.
- What is a good client churn rate for agencies?
- Target monthly churn under 5% (annual churn under 50%). Best agencies achieve 2-3% monthly churn. Above 8% monthly churn indicates service or fit issues. Calculate: (Clients Lost ÷ Starting Clients) × 100. Also track revenue churn, which should be lower due to upsells.
- How much should billable utilization be at an agency?
- Target billable utilization is 65-75%. Below 60% means excess capacity or too much admin work. Above 80% leads to burnout and quality issues. Calculate: (Billable Hours ÷ Total Available Hours) × 100. Senior staff typically have lower utilization (55-65%) due to management duties.
- What is the average agency retainer value in 2026?
- B2B marketing agency retainers average $5,000-15,000/month in 2026. Specialized agencies (SEO, paid media, ABM) command $8-20K. Full-service agencies range $15-50K. Micro-agencies typically price $3-8K. Retainer pricing should support 25%+ profit margin after fully-loaded costs.
Contextual ROI: The Intangibles
Contextual ROI: The Intangibles
Agency revenue is only part of the picture. These factors determine long-term agency health and valuation:
Referral Engine Health
Top agencies get 40-60% of new clients from referrals (near-zero CAC). If referrals are below 30%, client satisfaction or case study development needs work.
Team Retention Economics
Employee turnover costs 50-200% of annual salary. A $75K/year employee leaving costs $37-150K in recruiting, training, and lost productivity. Retention directly impacts profitability.
Intellectual Property Value
Proprietary frameworks, tools, and processes increase agency valuation by 0.5-1.5x revenue multiple. 'We do content marketing' is worth less than 'We use our proprietary Intent Framework™.'
