This calculation answers one practical question: how much of a person's available work capacity turned into billable or productive work. On Chrome, the math stays the same as it does on any modern browser, so use the page beside your timesheet, project report, or payroll spreadsheet. The useful result is the percentage, not the device or browser used to enter the hours.
For a U.S. team, 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.
A 40-hour weekly capacity baseline equals 2,080 gross annual hours before subtracting company PTO, holidays, unpaid leave, or other nonworking time. That gross number works for high-level planning. A net denominator works better when you compare actual delivery capacity, because it removes approved absences that the person was not available to work.
The FLSA does not require payment for time not worked, including vacations, sick leave, federal holidays, or other holidays. Private-sector paid holidays and paid leave come from employer policy unless another law or contract applies. OPM lists 11 federal holidays in 2026 for federal employees, but those dates become private-sector denominator reductions only when the employer treats them as paid nonworking days.
Use this formula: utilization rate = billable hours ÷ available hours × 100. Billable hours are the numerator. Available hours are the denominator after you choose gross capacity or net working capacity. Keep training, internal meetings, admin time, sales work, holidays, paid leave, and unpaid leave out of the numerator unless your firm explicitly treats that category as productive utilization.
For example, a consultant records 31 billable hours in a week with 40 available hours. The utilization rate is 31 ÷ 40 × 100 = 77.5%. At a $150 standard billing rate, those 31 billable hours carry $4,650 of billable value. The percentage explains capacity use, while the dollar value helps managers connect utilization to revenue planning.
Chrome works well for a quick utilization check because you can keep the source report open in one tab and the calculator in another. Copy hours from the weekly timesheet, paste the billable total first, then enter the available capacity. Browser autofill can speed repeated entries, but it does not verify whether the denominator excludes PTO, holidays, or unpaid leave correctly.
The common mistake is mixing a net numerator with a gross denominator without making that choice visible. A person who worked 31 billable hours during a week with one paid holiday has a different utilization story under a 32-hour net denominator than under a 40-hour gross denominator. Use the same denominator rule across the team before ranking performance.
A one-off calculator is enough when you need a quick weekly percentage, a client staffing check, or a single utilization figure for a spreadsheet. It is also enough when the hours already come from approved records and the denominator rule is already documented. The calculator gives the answer, but it does not create an approval trail.
A managed workflow matters when utilization feeds billing, payroll review, capacity planning, or performance reporting. Everhour Time Tracking captures task and project hours through timers or manual entries, works inside supported project tools, and sends approved time into timesheets, reporting, budgeting, invoicing, and payroll review. Admin controls such as approvals, locked periods, reminders, and timer rules keep repeated utilization reviews tied to governed records.

Divide billable hours by available hours, then multiply by 100. A person with 31 billable hours and 40 available hours has 77.5% utilization. Use the same denominator policy across comparable employees, because gross capacity and net working capacity produce different percentages.
PTO and holidays reduce available hours when your firm uses a net-working-hours denominator. The FLSA does not require payment for time not worked, including vacations, sick leave, or holidays, so private-sector paid leave depends on employer policy unless another law or contract applies.
U.S. federal sources do not set a professional-services utilization target. The target utilization rate is a firm, role, service line, or industry benchmark choice. Federal work-hour and leave rules help define capacity inputs, but they do not supply a national utilization percentage.
Overtime hours belong in the denominator only when your policy treats actual extra working time as available capacity for that period. Federal overtime rules require covered nonexempt employees to receive overtime pay for hours worked over 40 in a fixed 168-hour workweek, but that pay rule does not create a utilization target.
Chrome does not change the formula or the labor assumptions. The useful Chrome-specific workflow is keeping the source timesheet, project report, or payroll export open in another tab while you enter billable hours and available capacity. Saved form values help speed repeat checks, but they do not validate the underlying hours.
Everhour Time Tracking records task and project hours through live timers or manual entries, then feeds approved time into timesheets and reporting. Admins can use approvals, locked periods, reminders, and timer rules so utilization calculations draw from reviewed work records.
Everhour embeds time tracking in supported tools such as Asana, ClickUp, GitHub, Linear, Jira, Monday, Notion, Trello, and Basecamp. Teams can keep logging time where work happens while tracked hours flow into one reporting layer for budgets, utilization, and billing.
Track approved hours where work happens, then use Everhour Time Tracking to connect utilization reviews with timesheets, budgets, invoicing, and payroll review.
