Overview
Utilization rate measures what percentage of available working time is spent on billable or productive activities, serving as a key indicator of resource efficiency and profitability in professional services.
Calculation
Utilization Rate = (Billable Hours / Total Available Hours) × 100
Example
- Total available hours: 40/week
- Billable hours logged: 28/week
- Utilization rate: 28 ÷ 40 = 70%
Industry Benchmarks
- Consulting Firms: 70-85% target
- Law Firms: 65-75% for partners, 75-85% for associates
- Creative Agencies: 60-75% target
- Software Development: 70-80% for billable roles
Components
