Agency utilization answers a practical operating question: out of the hours a person or team was available to work, how many became client-billable time? The standard agency formula is billable hours divided by available hours, multiplied by 100. The numerator includes client-billable work only. The denominator must match the agency view you want: gross capacity, working capacity after leave, or another defined capacity base.
The result helps agency leaders compare staffing against demand, spot underused delivery capacity, and check whether a role target is realistic. Agency targets usually sit in the 60% to 85% range, with higher targets for delivery-heavy roles and lower or no billable-utilization targets for management, sales, and internal operations roles. A blended agency total needs role context, because averaging designers, account leads, and owners into one number hides the staffing signal.
A fixed weekly denominator treats a full-time person as available for the whole workweek. In the United States, the FLSA does not define full-time employment, so full-time capacity is an employer policy choice rather than a federal legal threshold. Many agencies use 40 weekly hours because federal overtime rules require covered nonexempt employees to receive overtime pay for hours worked over 40 in a fixed 168-hour workweek.
A working-time denominator removes leave, sickness, and similar absence from available hours. That view is cleaner for judging performance during the hours someone was actually available. The FLSA does not require payment for time not worked, including vacations, sick leave, or federal or other holidays, so private-sector paid leave depends on employer policy unless another law or contract applies. Using total logged hours as the denominator creates a common mistake: missed non-billable entries raise the utilization percentage.
Use this formula: billable utilization = billable client hours / available hours × 100. A senior designer with a 40-hour weekly capacity logs 34 client-billable hours and 6 internal agency hours. The utilization rate is 34 / 40 × 100 = 85%. The internal hours still matter for workload review, but they do not enter the billable-utilization numerator.
Realization answers a separate revenue question. If those 34 billable hours have a standard value of $4,250 and the client is billed $3,825 after a write-down, realization is 90%. Utilization says how much capacity became billable work. Realization says how much recorded billable value became revenue. Agencies need both numbers before deciding whether a team has a staffing problem, a pricing problem, or a scope-control problem.
A one-off calculation is enough for a quick check on one employee, one week, or one staffing scenario. It works when the inputs are already clean: billable hours, capacity, leave treatment, and role target. It also works for a sales planning question, such as estimating whether a new retainer needs another designer or can fit inside current delivery capacity.
A managed workflow becomes necessary when the agency needs the same calculation every week across roles, projects, and leave schedules. Everhour Time Off tracks vacations, sick leave, custom leave types, partial-day durations, accrual, carryover, and balances, then time-off data flows into timesheets and reports. That keeps working-capacity utilization tied to approved absences instead of a separate spreadsheet.

Agency utilization targets are normally set by role and business model. A delivery-heavy designer, developer, or strategist can carry a higher target, often inside a 60% to 85% range. Account management, sales, leadership, and internal operations roles usually need lower billable targets because their non-billable work supports revenue, retention, and delivery quality.
PTO should reduce available hours when the agency measures working-time utilization. That denominator asks how much available working time became client-billable work, so leave and similar absence stay outside the base. A total-capacity view can keep PTO in the denominator, but the report label must make that choice clear.
Total logged time overstates utilization when people under-record non-billable work. The formula becomes billable hours divided by recorded hours, so missing admin, sales, or internal project time makes the denominator too small. Available capacity is a cleaner denominator because it does not reward incomplete time entry.
Agency utilization can exceed 100% when billable hours are higher than the chosen capacity denominator. A person with 44 billable hours against a 40-hour capacity week reports 110% utilization. That result signals overtime, overbooking, or a short-term delivery push, not a sustainable target.
Utilization measures the share of available capacity spent on client-billable work. Realization measures billed value divided by the standard value of recorded billable time. High utilization with low realization points to write-downs, discounts, or unbilled scope. Low utilization with strong realization points to available capacity or demand planning.
Everhour Time Off tracks vacations, sick leave, custom leave types, partial-day absences, accrual, carryover, and per-employee balances. Approved time-off data flows into timesheets and reports, so agency utilization can use working capacity after absences instead of manually adjusting leave in a separate spreadsheet.
Everhour Reporting turns logged time, billable time, costs, budgets, and project data into customizable reports with columns, filters, grouping, date ranges, and exports. Agencies can group utilization by member, role, project, or client, then compare delivery teams without mixing them blindly with management or internal roles.
Track approved leave, billable time, and working capacity in one reporting flow. Everhour Time Off keeps agency utilization aligned with real availability and cleaner billing decisions.
