Employee Utilization Calculator

Measure how efficiently your team's time is being used — and identify capacity for more billable or productive work.

Utilization rate = Billable (or productive) hours ÷ Total available hours × 100. A 75% utilization rate means an employee spends 75% of their working hours on billable or value-generating work. The remaining 25% covers admin, meetings, training, and non-billable tasks.

Billable / Productive Hours

Hours spent on client work or direct value-generating tasks per week

Total Available Hours

Total working hours per week (typically 40)

Hourly Billable RateOptional — calculates revenue impact

Revenue generated per billable hour

Number of EmployeesOptional — shows team-level revenue

Team size (for aggregate calculation)

The Formula

Utilization % = Billable Hours ÷ Available Hours × 100

In plain English

Divide billable hours by total available hours and multiply by 100.

Worked Example

30 billable hours ÷ 40 available hours = 75% utilization. At $150/hr: 30h × $150 × 48 weeks = $216K annual revenue per employee.

Target Utilization by Industry

Target utilization varies by role and industry. Consulting and professional services: 70–80%. Software development: 65–75% (lower to allow for learning and innovation). Sales: measured differently via quota attainment. Creative agencies: 60–70%.

The hidden cost of low utilization: a 10-person team at 60% utilization vs 75% represents 60 hours of unused capacity per week. At $150/hr, that's $432K of annual revenue left on the table.

Common Mistakes

⚠️

Targeting 100% utilization

No buffer for innovation, training, or admin makes teams brittle and resentful. 100% utilization is a short-term illusion that destroys long-term productivity and retention.

⚠️

Measuring utilization without measuring output quality

High utilization with poor quality output is worse than moderate utilization with excellent output. Track billable hours alongside client satisfaction and rework rates.

⚠️

Applying the same target to all roles

Client-facing roles, internal support roles, and management have different utilization dynamics. Set appropriate targets per role, not a single company-wide number.
