- Annual overhead (rent, software, non-billable staff, insurance, marketing)
What You'll Get
- Total annual staff cost

Important Notes — 2025/26 Rates & Caveats
Agency benchmarks for 2025/26: healthy gross margin is 50–60% (staff cost as 40–50% of revenue); net margin after overhead is typically 10–20% for a well-run agency. Utilisation below 60% is a warning sign — staff time not billed is the primary margin destroyer. Overhead costs for a mid-size agency: office rent £10,000–£30,000/person/year in London, £5,000–£15,000 outside London. Agency management software (e.g. Harvest, Forecast, Teamwork) typically costs £15–£40/user/month. Employer NI from April 2025 is 15% (increased from 13.8% on earnings above the secondary threshold of £5,000).
Frequently Asked Questions
What is a healthy gross margin for a UK creative agency?
A healthy gross margin for a UK creative agency is 50–60%. This means staff cost (salaries + employer NI + pension + benefits) should represent 40–50% of revenue. Below 40% gross margin, the agency is unlikely to cover overhead and generate profit. The best-performing agencies maintain gross margins of 55–65% by managing utilisation closely and pricing value-based rather than time-based.
What is agency utilisation and what should it be?
Utilisation is the percentage of an agency's available staff time that is billed to clients. A 70% utilisation rate means a staff member with 220 available working days bills 154 days per year. Typical target utilisation: senior creatives 65–70%; account managers 70–75%; junior creatives 60–65%. Below 60% signals over-staffing or low workload; above 80% risks burnout and quality deterioration. Utilisation is tracked via timesheets in agency management software.
How do I calculate the blended day rate for my agency?
The blended day rate is the average daily revenue per fee-earner needed to hit your margin target. Formula: (total annual staff cost ÷ gross margin target) ÷ billable days. Example: 5 staff at £50,000 total annual cost each = £250,000. At 50% gross margin target, revenue needed = £500,000. At 70% utilisation × 220 days = 154 billable days per person × 5 = 770 billable days. £500,000 ÷ 770 = £649/day blended rate.
