What billable utilization means

Utilization is the percentage of working time that can be billed to a client. A 75% target across 40 working hours means 30 billable hours and 10 non-billable hours.

Billable hours = total working hours × utilization percentage

Revenue is not profit

The revenue estimate does not subtract wages, taxes, software, overhead or uncollected invoices. The annualized figure simply scales the selected period to 52 weeks, 12 months or one year.
