Most agencies target a 60–70% billable utilization rate for account managers, lower than the 75–85% expected of pure delivery roles like designers or developers. Account managers split time between billable client work and non-billable relationship management, internal coordination, and admin, so a healthy benchmark balances client revenue against the client-facing overhead that keeps accounts alive.
What utilization rate actually measures
Utilization rate is the percentage of an employee's available hours spent on billable work. The standard formula is:
Utilization Rate = (Billable Hours / Total Available Hours) x 100
If an account manager has 160 available hours in a month and logs 100 billable hours, utilization is 62.5%. Total available hours usually means working hours minus PTO and holidays, though some agencies use the full 40-hour week as the denominator. That choice matters a lot, and it's where most teams get their reporting wrong. Pick one definition and stick to it across the whole agency.
Billable vs. non-billable for account managers
Account managers carry a heavier non-billable load than other roles by design. Their non-billable time includes:
- Internal status meetings and team coordination
- Account planning and forecasting
- Proposal writing and scoping new work
- Relationship-building that doesn't map to a timesheet code
- Administrative tasks like invoicing reviews and CRM updates
That overhead is the reason a 60–70% target is realistic. Pushing AMs toward 85% usually means they stop doing the strategic account work that drives retention and expansion revenue.
Recommended benchmarks by agency type
Utilization targets shift depending on agency model, seniority, and how account management is structured.
| Role / context | Recommended utilization | Notes |
|---|---|---|
| Junior account manager | 70–80% | More execution, less strategy |
| Senior account manager | 55–65% | Heavier business development and oversight |
| Account director | 40–55% | Mostly relationship and growth focus |
| Hybrid AM (delivery + account) | 70–75% | Common in small agencies |
| Pure delivery roles | 75–85% | For comparison |
Senior people should carry lower billable targets, not higher. Their value is in renewals, upsells, and steering, which rarely shows up cleanly as billable time. Agencies that ignore this end up with directors buried in execution and no one growing the book.
Industry reference points
The widely cited benchmark from agency operations data, including resources from the Society of Digital Agencies and benchmarking surveys, puts agency-wide blended utilization around 70%. Tools like Float and resource-management vendors publish similar ranges and break them down by role. Treat these as starting points, not gospel, your service mix changes the math.
How to calculate a realistic target
Back into your target from your financial model rather than copying a benchmark blindly.
- Start with revenue goals. Determine how much billable revenue each AM needs to generate.
- Divide by billable rate. That gives required billable hours.
- Compare against available hours. Subtract realistic PTO, training, and internal time.
- Sanity-check the percentage. If the math demands 90% utilization, the model is broken, not the person.
This exercise often exposes underpricing. If you need 88% utilization just to hit margin, raise rates instead of squeezing capacity. Healthy account management also depends on solid pipeline qualification, so pairing utilization tracking with a structured sales discovery process keeps AMs from chasing low-fit work that tanks their billable ratio.
Signs your benchmarks are off
- Utilization above 85% consistently — burnout risk, no time for account growth
- Utilization below 50% — overstaffing, poor pipeline, or scope leakage
- High utilization but low realization — billing hours you can't collect on
- — uneven account loads or inconsistent time tracking
