How much of your week is billable?

Billable utilization rate = billable hours ÷ total hours worked × 100. Someone who works 40 hours and bills 30 is at 75%. Agencies typically aim for 75–85% for designers, developers and writers, 40–60% for account managers and leads, and 60–70% across the whole team.

Your team, in a typical week
Billable means hours you invoice or that count against a retainer. Internal meetings, sales, admin and unbilled “quick favours” are not billable.
Year and target
The billable utilization formula
The rate itself is simple. The value is in pricing the gap: hours that could be billable, multiplied by what they bill at.
- Billable hours
- Time on client work that is invoiced or counts against a retainer.
- Hours worked
- All hours actually worked, including overtime. Not contracted hours.
- Working weeks
- 52 minus holidays, vacation and sick days. 46 is typical.
- Bill rate
- The rate the hour is billed at. For retainers, use the effective rate: retainer ÷ hours delivered.
One designer, one extra hour
A designer works 40 hours a week and bills 29, at $95 an hour: 29 ÷ 40 = 72.5% utilization. Over 46 working weeks that is 1,334 billable hours, or $126,730 of billable work.
Reaching a 75% target means 30 billable hours a week, one more than today.
One extra billable hour a week is worth $4,370 a year from this one person.
Utilization targets by role
Ranges widely used in agency and professional-services planning. Set targets by role, not one number for everyone.
| Role | Typical target | Why |
|---|---|---|
| Designers, developers, writers | 75–85% | Most of the week is client delivery |
| Strategists and senior specialists | 60–75% | Time for planning, reviews and pitching |
| Account and project managers | 40–60% | Coordination is mostly non-billable |
| Team leads and creative directors | 40–60% | Mentoring, hiring and quality control |
| Founders and owners | 20–40% | Sales, finance and running the business |
| Whole agency, blended | 60–70% | The mix of the roles above |
Running above 85% for weeks at a time is a burnout and quality risk, not a win.
How to calculate billable utilization
- 1
Pick a period
Use a typical week, or last month’s totals divided by the number of weeks.
- 2
Enter hours worked
Actual hours for each person or role, including overtime.
- 3
Enter billable hours
Hours that were invoiced or counted against a retainer. Unbilled client favours don’t count.
- 4
Add bill rates
Hourly rate, or the effective retainer rate, for each person.
- 5
Set weeks and a target
Working weeks per year and the target utilization you plan against.
- 6
Price the gap
Read the revenue gap and the value of one point, then decide where to win hours back.
Raise utilization without burning people out
Bill the small requests
Five-minute favours add up to hours of real client work that never becomes billable. Quote them.
Cut internal meetings
A weekly hour-long meeting for five people is 240 non-billable hours a year.
Log time daily
Time logged at the end of the week is guessed, and guesses miss the small billable tasks.
Fix waiting time
Slow approvals and unclear briefs leave people idle. Set feedback deadlines in the scope.
Plan capacity before you sell
Low utilization is often a sales problem. Know your free hours before the pipeline review.
Keep a buffer
100% isn’t the goal. Leave room for training, fixes and the unexpected.
What is billable utilization?
The share of working time spent on work you can bill to a client, or that counts against a retainer. Internal meetings, sales, admin, training and unbilled favours for clients are all non-billable.
How do you calculate the utilization rate?
Divide billable hours by total hours worked over the same period and multiply by 100. For a team, add up everyone’s billable hours and divide by everyone’s hours worked: 90 billable hours out of 170 worked is 53%.
What is a good billable utilization rate for an agency?
For people whose job is delivery, 75–85% is a common target. Account managers, team leads and strategists usually sit at 40–75% because coordination and mentoring are not billable. A blended agency-wide rate of 60–70% is typical for a healthy agency.
Should I calculate against 40 hours or actual hours worked?
Actual hours worked gives the honest picture: someone working 50 hours and billing 30 is at 60%, not 75%. Calculating against a 40-hour week hides overtime and makes burnout look like high performance.
What is the difference between utilization and realization?
Utilization measures how many hours were billable. Realization measures how much of the value of those hours you actually invoiced and collected. Discounts, write-offs and unbilled “quick requests” hurt realization even when utilization looks fine.
Why is my team’s utilization low?
The usual causes are too many internal meetings, waiting on client approvals, poor handoffs, under-selling (not enough work booked) and client work done but never logged or billed. Small out-of-scope favours are a big one: real work, done for clients, that never shows up as billable.
Can utilization be too high?
Yes. Above 85% for weeks at a time leaves no room for training, process improvement or sick days, and quality and retention usually suffer. Plan for a buffer.
