Utilization depends on billable hours and firm-defined capacity. Everhour Reporting helps turn tracked work into useful reports.
Measure billable utilization against total capacity and see exactly how many hours you're leaving on the table each period.

A utilization rate shows the share of available work capacity that became billable, client-facing, or otherwise productive under your firm's definition. On an iPhone, the math stays the same as on a desktop: billable hours divided by available hours, then multiplied by 100. The practical value is speed. You can check a weekly number from a timesheet, invoice draft, or staffing note without opening a full spreadsheet.
For U.S. teams, the denominator comes from company policy. The FLSA does not define full-time or part-time employment, so full-time capacity is an employer policy input rather than a federal legal threshold. Many firms start with 40 hours per week because federal overtime rules require covered nonexempt employees to receive overtime pay for hours worked over 40 in a fixed 168-hour workweek.
Utilization changes when you choose gross capacity, net working capacity, or scheduled capacity. A 40-hour weekly baseline equals 2,080 gross annual hours before company PTO, holidays, unpaid leave, or other nonworking time. A net-working-hours denominator subtracts approved absences. Actual-hours data is different from gross capacity because it excludes time not worked for holidays, annual paid leave, illness, maternity or parental leave, and similar absences.
U.S. federal law does not mandate paid vacation or holiday time for private employers under the FLSA. OPM lists 11 federal holidays in 2026 for federal employees, while private-sector paid holidays depend on employer policy, law, or contract. Eligible employees of covered employers may take up to 12 workweeks of unpaid, job-protected FMLA leave in a 12-month period, and actual leave taken should reduce available hours when your firm uses a net-working-hours denominator.
The core formula is utilization rate = billable hours / available hours * 100. If a consultant has 48 billable hours and 64 available hours in a two-week period, utilization is 75%. At a $142 standard hourly billing rate, those 48 billable hours carry $6,816 of billable value before discounts, write-downs, or invoice adjustments.
The same employee can show different utilization under different denominator rules. If the firm uses 80 gross hours for the same two-week period, 48 billable hours equals 60% utilization. If one approved leave day reduces available capacity to 72 hours, the same 48 billable hours equals 66.67%. The calculation is only useful when the numerator and denominator follow the same policy every period.
A one-off calculation is enough when you need a quick answer for one person, one week, or one invoice review. Keep the source data open in another iPhone tab, then copy billable hours, available hours, and rate into the calculator. This works for spot checks, freelancer planning, and small client updates where no approval trail is required.
A managed workflow becomes necessary when utilization feeds payroll review, staffing decisions, billing, or recurring management reports. Everhour Reporting turns logged time, budgets, costs, and project data into customizable reports with grouping, filters, date ranges, exports, and scheduled email delivery. That matters when the utilization number must trace back to approved time entries instead of a manual note.

A utilization rate measures the percentage of available capacity spent on billable or productive work under your firm's definition. The standard formula is billable hours divided by available hours, multiplied by 100. A 75% result means 75 out of every 100 available hours were counted as billable or productive.
An iPhone does not change the utilization formula, inputs, or result. The same billable hours, available hours, PTO adjustments, and billing-rate assumptions produce the same percentage on any device. The iPhone-specific advantage is workflow: you can check a number while reviewing a mobile timesheet, email approval, or invoice draft.
Federal holidays reduce available U.S. capacity only when your employer policy, contract, or applicable rule treats them as nonworking paid holidays. OPM lists 11 federal holidays in 2026 for federal employees. Private-sector paid holidays are not mandated by the FLSA, so a private employer's utilization denominator should follow its own policy.
Mixing gross capacity with a net-hours numerator distorts utilization. For example, counting billable hours after PTO but leaving the denominator at full gross capacity makes utilization look lower than the employee's true available-time performance. Pick gross annual capacity, net working capacity, or scheduled capacity, then apply it consistently across people and periods.
There is no statutory U.S. utilization target for professional-services teams. Federal sources define work-hour and leave rules, but they do not set a required billable percentage. Target utilization should come from firm role, service line, pricing model, and industry benchmarks rather than country-level law.
Everhour Reporting turns logged time, budgets, costs, and project data into customizable reports with 45+ columns, metadata filters, grouping, date ranges, and exports. Teams can review utilization by member, project, client, or period, then schedule recurring email reports for managers who need the same view every week.
Track approved hours in Everhour, group them by member or project, and schedule recurring utilization reports so manual calculator checks become repeatable reporting.
