Overview
Utilization rate measures what percentage of an employee's total available time is spent on billable client work. It's a critical metric for professional services firms including law firms, consulting firms, and agencies.
Calculation
Utilization Rate = (Billable Hours / Total Available Hours) × 100
Example
- Total hours available per year: 2,080 (40 hrs/week × 52 weeks)
- Billable hours achieved: 1,500
- Utilization rate: 1,500 / 2,080 = 72%
Target Rates by Role
Senior Partners/Executives: 40-60% (More business development, management)
Mid-level Professionals: 70-80% (Mix of billable work and internal duties)
Junior Staff: 75-85% (Primarily billable work)
Industry Averages:
- Law firms: 65-75%
- Consulting: 60-75%
- Architecture/Engineering: 55-65%

Realization Rate
Related metric: Realization = (Revenue Collected / Hours Billed)
Both utilization and realization matter:
- High utilization + high realization = profitable
- High utilization + low realization = efficiency problem
- Low utilization + high realization = capacity problem
