Utilization depends on disciplined hour classification. Everhour turns tracked time into reports that separate billable work from capacity.
Measure billable utilization against total capacity and see exactly how many hours you're leaving on the table each period.

Tracking utilization answers a practical management question: how much of a person's available capacity turns into billable client work. The usual services formula is billable hours divided by available hours, then multiplied by 100. The result matters for staffing, pricing, hiring, and workload balance because it shows whether paid capacity is being converted into revenue-generating work.
The denominator needs a written definition before the rate means anything. A U.S. firm often starts with 40 weekly hours as gross capacity because federal overtime rules require covered nonexempt employees to receive overtime pay for hours worked over 40 in a fixed 168-hour workweek. That baseline is a company operating choice for utilization, since the FLSA does not define full-time employment.
Utilization changes when the denominator changes. Gross capacity counts scheduled capacity before absences. Net working capacity subtracts company PTO, holidays, unpaid leave, and other nonworking time. Total logged hours uses the time a person recorded, which can hide untracked capacity gaps. Name the denominator beside every utilization figure so managers compare the same metric.
A consultant with 32 billable hours in a week with one 8-hour paid holiday shows the difference. Gross capacity gives 32 ÷ 40 × 100 = 80%. Net working capacity gives 32 ÷ 32 × 100 = 100%. The same billable work swings 20 percentage points because the holiday changes available hours under the net method.
Utilization is a capacity conversion metric. Realization compares billed value with billable value or billed hours with billable hours, depending on the firm's definition. Efficiency compares output against input. Productivity can mean tasks completed, revenue per person, or another operating measure. A fully utilized consultant is not automatically fully realized if write-offs, discounts, or unbilled time reduce revenue.
Track each metric with its own numerator and denominator. Billable utilization uses billable hours over available hours. Total utilization can use all logged work over available hours. Capacity utilization in services often means used capacity over planned capacity, while manufacturing uses output over potential output. Mixing those families creates false trends and pushes managers toward the wrong fix.
A one-off calculation is enough when you need a quick answer for one person, one week, or one project review. Spreadsheet math works if the billable classification is already clean, the capacity denominator is written down, and leave data is complete. The risk rises when people submit late time, managers recode work, or targets differ by role.
A managed workflow fits recurring utilization review. Everhour Reporting can group logged time by member, project, client, or metadata, filter billable and non-billable work, and export reports in CSV, Excel/XLSX, or PDF. That turns utilization from a manual weekly check into a repeatable reporting handoff for staffing, billing review, and target tracking.

Use hours tied to client work that the firm treats as billable under its engagement rules. Exclude internal meetings, training, administration, business development, and leave unless the firm's policy explicitly classifies a category as billable. Keep written categories stable so changes in utilization reflect work patterns instead of recoding habits.
A percentage without a denominator label can describe different realities. A 75% rate against 40 gross weekly hours means 30 billable hours. A 75% rate against 32 net working hours means 24 billable hours. Label each figure as gross capacity, net working capacity, scheduled capacity, or total logged hours before comparing people or teams.
Paid holidays reduce available hours only when the firm uses a net-working-hours denominator. The FLSA does not require payment for time not worked, including vacations, sick leave, or federal or other holidays. OPM lists 11 federal holidays in 2026 for federal employees, while private-sector paid holidays depend on employer policy unless another law or contract applies.
Actual leave taken should reduce available hours when the firm uses a net-working-hours denominator. Eligible employees of covered employers may take up to 12 workweeks of unpaid, job-protected FMLA leave in a 12-month period for qualifying reasons. Counting those absent hours as available capacity would understate utilization for the period.
U.S. federal sources define work-hour and leave rules, but they do not set a professional-services utilization target. A target utilization rate is a firm or industry benchmark choice. Delivery roles often need different targets than managers, sales-support roles, or internal operations roles because their expected billable mix is different.
Everhour Reporting turns logged time, budgets, costs, and project data into customizable reports with 45+ columns. Teams can group by member, project, or client, filter billable and non-billable time, set date ranges, and export reports for utilization review.
Everhour Resource Planning shows team workload on a visual timeline with weekly capacity per person. Managers can compare planned capacity with actual tracked time, see time off on the schedule, and spot overallocated people before assigning more client work.
Track approved hours, classify billable work, and review utilization by person, project, or client. Everhour Reporting gives teams a repeatable way to compare capacity with billable output.
