A utilization rate shows the share of available working time that became billable time. The core ratio is billable hours divided by available hours, then multiplied by 100. A consultant with 126 billable hours and 160 available hours has 78.75% utilization. That result answers a practical staffing question: how much of this person's capacity produced billable work during the selected period.
The online version is enough when you need a fast percentage for one person, one team, or one project period. It does not set the target. U.S. federal sources do not create a statutory national utilization target, and the FLSA does not define full-time or part-time employment. Firms set the target by role, service line, pricing model, and staffing policy.
Use this formula: billable hours ÷ available hours × 100 = utilization rate. Billable hours are client-chargeable work. Available hours are the capacity denominator you choose, such as gross scheduled capacity, working hours net of PTO and holidays, or total logged time. The percentage changes when the denominator changes, even when billable hours stay the same.
For example, use 126 billable hours and 160 available hours for a monthly calculation. Divide 126 by 160 to get 0.7875, then multiply by 100 to get 78.75%. If the same person had 144 net available hours after approved time off, the rate becomes 87.5%. Label the result as gross-capacity utilization or net-working-hours utilization so the reader knows which denominator produced it.
An online calculator reduces friction because you can enter two numbers and get a result without installing software or building a spreadsheet. That speed helps during staffing reviews, client-margin checks, and quick month-end audits. The common mistake is treating every available-hours field as the same number. Gross capacity, net working hours, and total logged hours answer different operational questions.
A 40-hour weekly baseline gives 2,080 gross annual hours before PTO, holidays, unpaid leave, and other absences. Many U.S. firms start there because federal overtime rules require covered nonexempt employees to receive overtime pay for hours worked over 40 in a fixed 168-hour workweek. Private-sector paid holidays and paid vacation remain employer-policy items unless another law or contract applies, so net them out only when your denominator policy says to.
A one-off calculator works for spot checks, proposal planning, and a quick comparison between two denominator choices. It also works when a freelancer wants to see whether the month had enough billable work. A spreadsheet or online tool is sufficient when the input hours already exist, the period is short, and no one needs an approval trail.
A managed workflow becomes necessary when several people submit time, managers approve periods, time off affects capacity, and utilization feeds staffing or billing decisions. Everhour Team Management supports weekly capacity, roles, project assignments, team groups, approval workflows, lock rules, and admin time correction, so the same capacity policy can carry from timesheets into utilization reviews.

Yes. Gross capacity is valid when you label it clearly, such as billable hours divided by scheduled capacity. For U.S. teams, a 40-hour weekly baseline equals 2,080 gross annual hours before subtracting company PTO, holidays, unpaid leave, or other nonworking time. A gross-capacity rate runs lower than a net-working-hours rate when leave is excluded from the second denominator.
No. BLS classifies workers as full time in CPS statistics when they usually work 35 or more hours per week, but BLS states that this is a statistical definition. It does not create a legal full-time threshold for a firm utilization denominator. Your denominator should follow employer policy, role expectations, and the reporting question.
Remove federal holidays only when your policy treats them as nonworking paid time for the worker group in the report. OPM lists 11 federal holidays in 2026 for federal employees. Private-sector paid holidays remain a matter of employer policy unless another law or contract applies, so the denominator should match the company's actual paid-holiday rules.
Two calculators give different results when they use different denominators, rounding rules, or billable classifications. One tool may divide by gross scheduled capacity, while another divides by working hours after PTO and holidays. Another may count only approved billable time. The right comparison uses the same period, same billable-hours rule, and same available-hours definition.
No. Utilization measures billable hours as a share of available capacity. Realization measures how much billable or worked time becomes billed or collected revenue under the firm's pricing and write-off rules. A person can have high utilization and lower realization if the project records many billable hours that are discounted, written off, or billed under a capped fee.
Everhour Team Management lets admins set weekly capacity, assign roles and projects, group teams, approve timesheets, lock completed periods, and correct time entries. Those controls keep capacity and approved hours consistent before managers review utilization by person, group, or project.
Everhour Resource Planning shows member capacity and workload on a visual timeline, including time off and planned-vs-actual comparisons. Managers can see overallocated people, available bandwidth, and future capacity gaps before utilization problems appear in month-end reports.
Set capacity rules once, approve time before reporting, and use Everhour Team Management to keep utilization reviews grounded in approved hours, weekly capacity, and team structure.
