Every consulting firm tracks utilization. It's the fundamental measure of efficiency: what percentage of available hours are being billed to clients?
And every consulting firm has felt the pressure to push utilization higher. If 75% is good, isn't 85% better? If 85% is possible, why not 95%?
Here's why not.
The Visible Math
The math seems obvious. A consultant costs the firm roughly the same whether they're 70% utilized or 90% utilized. But at 90%, they generate 29% more revenue. That drops straight to the bottom line.
Push a 10-person team from 75% to 90% utilization and you've just created the equivalent of 2 additional consultants worth of revenue. Without hiring anyone.
This is the math that drives utilization pressure. And it's not wrong, as far as it goes.
The Hidden Costs
What the utilization math doesn't capture:
Burnout and turnover. Sustained high utilization is exhausting. People quit. The cost of replacing a consultant (recruiting, interviewing, onboarding, ramping) is typically 50-100% of their annual salary. One departure erases months of "extra" revenue.
Quality degradation. Consultants at 95% utilization don't have time to think. They execute, but they don't innovate. Deliverables get good enough, not great. Clients notice, eventually.
No capacity for growth. When everyone is maxed out, there's no one to staff the new opportunity that just came in. You either turn down work or staff it with people who are already stretched. Neither is good.
Business development dies. The partners and principals who should be developing new business are instead delivering on current work. Pipeline dries up. Revenue becomes lumpy.
No slack for problems. When a project goes sideways (and projects always go sideways), there's no reserve capacity to absorb the hit. The overage cascades across other projects.
The Right Utilization Target
The right target isn't maximum utilization. It's optimal utilization: the level that balances revenue generation against all the hidden costs.
For most consulting firms, that's somewhere between 70-80% for delivery staff, lower for those with business development responsibilities.
| Role | Target Utilization | Why |
|---|---|---|
| Partner | 40% | BD, relationships, firm leadership |
| Principal | 60% | Mix of delivery and BD |
| Senior | 75% | Primarily delivery, some mentoring |
| Consultant | 80% | Delivery focused |
These numbers give you slack. Slack for quality. Slack for growth. Slack for the unexpected.
Utilization as a Symptom
High utilization isn't always a choice. Sometimes it's a symptom of other problems:
Understaffing. You don't have enough people for the work you've sold. The answer is hiring, not squeezing existing staff.
Pricing too low. You need more hours to generate enough revenue because your rates don't reflect your value. The answer is raising prices, not working more hours.
Scope creep. Projects expand beyond what was sold, but you don't adjust staffing or timelines. The answer is better scope management, not free overtime.
Pipeline gaps. You have to take every project that comes in because you're not sure when the next one will come. The answer is better business development, not desperation staffing.
Pushing utilization higher masks these problems. It treats symptoms while the underlying disease progresses.
Managing Utilization Intelligently
Good utilization management isn't about maximizing a number. It's about:
Visibility. Knowing where you are across the team, in real-time, not reconstructed from timesheets at month end.
Balance. Identifying over-allocated individuals early, before they burn out. Finding under-allocated capacity before it becomes bench time.
Forecasting. Seeing what's coming (project ends, new starts, pipeline that might close) so you can plan rather than react.
Trade-offs. Understanding that utilization is one input to firm health, not the only one. Being willing to sacrifice some utilization for quality, growth, or sustainability.
This is harder than just pushing a number higher. But it's how you build a firm that lasts.
