Calculate billable utilization rate
Billable utilization rate measures the proportion of an employee's available working hours that are billed to clients. It is calculated by dividing billable hours by total available hours and multiplying by one hundred. A consultant who bills fourteen hundred of two thousand eighty available hours in a year has a utilization rate of about sixty-seven percent. It is a central metric for consulting firms, agencies and professional services, where billable time is the main source of revenue.
Available hours are usually the total working hours in the period, though some firms base it on target hours instead.
Why utilization matters
Utilization directly drives revenue and profitability in services businesses, since unbilled hours are hours that cost money without earning it. Firms track it to balance workload, price engagements and plan hiring. A utilization that is too low signals under-selling or overstaffing, while one that is too high can lead to burnout and leaves no time for business development, training or admin.
The ideal rate varies by role and firm, with sixty to eighty percent being common for billable staff. Interpreting utilization alongside billing rates and realisation gives the clearest view of profitability. All calculation happens locally in your browser.
