Billable utilization shows the share of available working time that turned into client-billable work. Total utilization shows the share of available working time that was used for tracked work overall, including non-billable delivery support, internal meetings, training, administration, and other productive time that does not become billable revenue.
The comparison matters because a person can look fully used while still producing too few billable hours. A 100% total utilization rate can hide a billable utilization shortfall if too much tracked time sits in non-billable categories. The gap tells a manager whether the issue is workload volume, billing classification, staffing mix, or too much internal work.
Both rates need the same denominator before the comparison means anything. Many U.S. firms start from a 40-hour weekly gross capacity baseline because federal overtime rules require covered nonexempt employees to receive overtime pay for hours worked over 40 in a fixed 168-hour workweek. That creates 2,080 gross annual hours before company PTO, holidays, unpaid leave, or other absences.
A net-working-hours denominator subtracts time not available for work. The FLSA does not require payment for time not worked, including vacations, sick leave, or federal or other holidays, so private-employer paid leave depends on employer policy unless another law or contract applies. OPM lists 11 federal holidays in 2026 for federal employees, but private-sector paid holidays remain policy-driven.
Use these formulas: billable utilization = billable hours ÷ available hours × 100. Total utilization = total tracked work hours ÷ available hours × 100. Total tracked work hours include billable hours plus non-billable work hours when your policy treats those hours as utilized capacity.
For one weekly example, a consultant has 40 available hours, 30 billable hours, and 8 non-billable project-support hours. Billable utilization is 30 ÷ 40 × 100 = 75%. Total utilization is 38 ÷ 40 × 100 = 95%. The 20-point gap shows that the consultant was busy, but one-fifth of available capacity did not convert into billable work.
A one-off calculation is enough for a spot check, a monthly management note, or a quick comparison between two denominator policies. It works when the inputs are already clean: available hours, billable hours, and non-billable tracked work hours for the same person or team and the same period.
A managed workflow is better when utilization affects staffing, billing, budgets, or performance reviews. Everhour Reporting can group and filter logged time by project, member, client, billable status, and date range, then export CSV, Excel/XLSX, or PDF reports. That gives managers a repeatable way to compare billable and total utilization against targets over time.

Total utilization includes non-billable work only when your firm defines the numerator as all tracked productive work. A common services definition uses billable hours plus approved non-billable work divided by available hours. Label the numerator clearly, because total utilization can mean total logged hours in one firm and total productive hours in another.
Total utilization is higher when a person records non-billable work that still consumes available capacity. Client administration, presales support, internal training, management meetings, and delivery support can raise total utilization without raising billable utilization. The difference is a utilization gap, measured in percentage points.
Both rates should use the same denominator for a fair comparison. Gross capacity often starts with 40 hours per week, or 2,080 annual hours. Net working hours subtract company PTO, holidays, unpaid leave, and other nonworking time according to policy. Mixing gross capacity for one rate and net hours for the other creates a false gap.
Yes. A person with 40 available hours, 24 billable hours, and 16 non-billable tracked hours has 60% billable utilization and 100% total utilization. That result signals a billing mix issue, not an idle-capacity issue. The next review should inspect non-billable categories before changing workload assignments.
No statutory national target exists. U.S. federal sources define work-hour and leave rules, but they do not set a professional-services utilization target. A firm sets target utilization by role, service line, seniority, delivery model, and industry benchmark rather than by federal law.
Everhour Reporting lets managers build reports with billable time, member, project, client, date range, labor cost, budget, and other columns. Grouping and filters separate billable hours from non-billable tracked work, so the same report can support billable utilization, total utilization, and the gap between them.
Everhour reports can be downloaded in CSV, Excel/XLSX, or PDF format for spreadsheet analysis, client sharing, or internal archives. That export workflow helps finance or operations teams review utilization inputs without rebuilding time data from separate task lists and timesheets.
Track billable and non-billable time in Everhour, then use customizable reporting to compare utilization by person, project, client, and period with cleaner billing decisions.
