A utilization rate answers one practical question: out of the hours a person was available to work, how many hours counted toward the work category you measure? On iPad, the math stays the same as on desktop. The useful workflow detail is screen space: keep source timesheets, PTO records, or project reports open in Split View so you can check each input before entering it.
For U.S. teams, the denominator comes from employer policy. The FLSA does not define full-time or part-time employment, so full-time capacity is not a federal legal threshold. Many firms start from 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.
The clean formula is billable hours divided by available hours, multiplied by 100. Available hours can be gross capacity or net working capacity. A 40-hour weekly baseline produces 2,080 annual gross hours before company PTO, holidays, unpaid leave, and other nonworking time reduce the denominator by policy.
Federal law does not require private employers to pay for time not worked, including vacations, sick leave, federal holidays, or other holidays. Private-sector paid holidays and paid vacation still belong in many utilization models because employer policy, contract terms, or another law can make them part of the working calendar. The denominator should match the benchmark you plan to use.
Use this formula: utilization rate = billable hours / available hours x 100. If a consultant records 38 billable hours in a 40-hour week, utilization is 95%. At a $125 billing rate, those 38 billable hours carry $4,750 of billable value.
The same inputs can show capacity economics. Divide $4,750 by the full 40 available hours, and the effective value across capacity is $118.75 per available hour. This second figure helps owners compare staffing, pricing, and write-downs without changing the utilization rate itself.
The United States has no statutory national utilization target. Federal sources define work-hour and leave rules, but they do not set a professional-services utilization percentage. A partner, project manager, engineer, and bookkeeper can have different targets because their jobs include different amounts of sales, admin, training, management, and nonbillable client support.
A common mistake is comparing a net-capacity calculation with a gross-capacity target. If your target assumes 2,080 annual hours, do not subtract PTO and holidays from the denominator before judging performance. If your firm target uses net working hours, subtract policy-based absences consistently for everyone in the same worker category.
A one-time calculator is enough when you need a quick weekly check, a proposal assumption, or a back-of-envelope staffing number. It works best when the inputs are already known: billable hours, available hours, and the target percentage.
A managed workflow matters when utilization drives scheduling, hiring, or project margin. Everhour Resource Planning uses visual timelines, member and project views, weekly capacity, availability gaps, scheduled time off, and planned-vs-actual time comparisons so managers can spot overbooking before a utilization number becomes a payroll or delivery problem.

Divide the measured work hours by available hours, then multiply by 100. For billable utilization, use billable hours as the numerator. For productive utilization, use the work category your firm defines as productive. Keep the denominator consistent with the target, either gross capacity or net working capacity after policy-based absences.
An iPad does not change the formula, inputs, or result. The practical difference is workflow. Use Split View to keep the source report next to the calculator, or save the page to the Home Screen when you run the same check often. The calculation remains billable hours divided by available hours times 100.
Many U.S. firms use 40 hours per week as a gross capacity baseline because federal overtime rules apply after 40 hours worked in a workweek for covered nonexempt employees. The FLSA does not define full-time employment, so a 40-hour denominator is a firm policy choice, not a federal full-time rule.
Paid holidays and PTO reduce available hours only 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. Private employer policy, contracts, or another applicable law can still make those absences part of the denominator design.
U.S. federal sources do not set a professional-services utilization target. Set targets by role, service line, seniority, and business model. A client-facing consultant usually carries a higher billable target than a manager who spends scheduled time on supervision, staffing, training, or sales.
Everhour Resource Planning shows team capacity on visual timelines with member and project views, weekly capacity, availability gaps, scheduled time off, and planned-vs-actual comparisons. Managers can see who is overallocated, who has room for more work, and how planned assignments compare with tracked time.
Use Everhour Resource Planning to compare scheduled capacity, time off, and actual tracked work before utilization gaps turn into missed margins or overloaded teams.
