Utilisation rate tells you the percentage of your team's total working hours that is spent on billable client work. It sounds simple. Most creative agencies still don't track it, and the ones that do often measure it wrong. That oversight quietly erodes margins, hides capacity problems, and makes accurate pricing nearly impossible.
A studio with 10 people working 40-hour weeks has 400 hours of potential capacity each week. If only 260 of those hours end up on client projects, the utilisation rate is 65%. The other 35% is absorbed by pitching, admin, internal meetings, professional development, and downtime between jobs. None of that is wasted in the abstract, but you need to know exactly where it goes before you can price services to cover it.
What counts as billable time
Before tracking anything, agree on your definition. Billable time is any hour that is directly charged to a client project or recoverable through project fees. Non-billable time includes new business activity, staff onboarding, internal reviews, and time spent on building pitch decks for prospects who haven't signed yet.
Some studios also include a third category: investment time. This covers work that doesn't bill today but builds future revenue, such as a speculative reel, a process template, or a training session that improves output quality. Tracking this separately stops it from dragging down your utilisation number and making the team feel punished for doing things that benefit the business.
The key rule: whatever you count, count it consistently. Changing the definition mid-year makes your data useless for trend analysis.
How to calculate it
The formula is straightforward:
- Billable hours logged divided by total available hours, multiplied by 100.
Total available hours should exclude statutory holidays, approved annual leave, and sick leave already taken. You're measuring utilisation against real working capacity, not a theoretical maximum that ignores that people take time off.
Run the calculation at three levels: individual, team, and studio-wide. Individual rates expose workload imbalances. One editor running at 90% while another runs at 40% is a resourcing problem, not a performance problem. Team-level rates help you see whether a department is generating enough revenue to justify its headcount. Studio-wide rates give leadership a single number to benchmark over time.
What a healthy utilisation rate looks like
For a creative agency, a studio-wide billable utilisation rate between 65% and 75% is a realistic and sustainable target. Below 60% and you're likely underpricing or carrying more overhead than your revenue supports. Above 80% sustained across the team and you're heading toward burnout, missed deadlines, and staff turnover.
Principals and senior creatives typically run lower than mid-level staff because they carry a heavier load of non-billable responsibilities: client relationship management, strategy, and business development. A studio director at 45% billable utilisation isn't underperforming; that may be exactly right for the role. The mistake is applying a single target across every position regardless of function.
Freelancers complicate the picture. When you bring in contract talent to cover a production surge, their hours should appear in your project costs but not distort your internal utilisation tracking. Keep staff and contractor hours in separate columns. Managing freelance creatives well means knowing when their hours are covering a genuine capacity gap rather than masking a structural staffing problem.
Common tracking mistakes
The most damaging mistake is relying on memory. Asking the team to log hours at the end of the week produces optimistic rounding. Real-time or same-day logging is more accurate and takes less cognitive effort than reconstructing a week from memory on Friday afternoon.
A second mistake is treating all non-billable time as equivalent. Pitching for a project that converts is not the same as an unfocused team meeting that produces nothing. If your agency invests 20 hours in a pitch that wins a $50,000 project, those 20 hours paid off. If the same 20 hours went into a pitch you knew you were unlikely to win, that's a different problem entirely. Tag non-billable time by category so you can see what non-billable activity is actually generating returns.
A third mistake is checking utilisation only monthly. By the time a low-utilisation month shows up in a report, three weeks of the next month may already be underbooked too. Weekly check-ins let you move work forward, bring in freelancers, or accelerate new business outreach while there's still time to affect the outcome.
Using utilisation to set smarter rates
Utilisation data feeds directly into pricing. If your studio runs at 70% billable utilisation and you want to cover all your costs with a profit margin, your effective hourly rate needs to account for the 30% of time that isn't billed. A team member whose total employment cost is $80 per hour needs to bill at a minimum of roughly $115 per hour at 70% utilisation just to break even, before profit.
Most agencies arrive at their rates through a different process: gut feel, competitor research, or rounding up from last year. Utilisation data replaces that guesswork with a specific number your business actually needs. That's the same discipline behind pricing video production services accurately rather than by approximation.
Run the calculation whenever you're preparing a services agreement, setting a retainer fee, or reviewing your rate card. A utilisation rate that has drifted down since the last pricing review means your current rates are now undercovering costs. The data tells you that before the bank account does.
The tools you need
You don't need enterprise software to track utilisation. Studios of 3 to 5 people can manage it in a shared spreadsheet with a consistent time-logging discipline. Studios of 10 or more benefit from dedicated time-tracking software. Tools like Harvest integrate project tracking with invoicing and produce utilisation reports automatically.
Whichever tool you use, the setup matters more than the brand. Create a project for every active client job. Create internal categories for pitching, administration, professional development, and investment time. Make logging as frictionless as possible. If it takes more than 90 seconds to log a task, people will batch-log at the end of the day and accuracy will suffer.
Review the raw data before it becomes a report. Numbers that look suspicious usually are. A team member logging 100% billable time week after week is almost certainly either underreporting non-billable activity or absorbing overhead into client projects. Both distort your understanding of real capacity.
Turning the number into a decision
Utilisation rate is a diagnostic, not a verdict. A low rate might mean you're between projects and need to accelerate new business. It might mean your project scheduling is creating gaps that better capacity planning could close. It might mean certain roles are misaligned with the work your studio actually wins. Each diagnosis leads to a different fix.
Track it monthly. Review it quarterly. Use it to test whether pricing changes, staffing changes, or workflow improvements are actually moving the business in the right direction. A studio that measures this properly isn't doing more admin. It's making fewer expensive decisions in the dark.
