Utilization = billable hours ÷ ((working days − days off) × hours per day).
Billability = billable hours ÷ all tracked hours.

How Billable Hours Turn Into Utilization

Billable hours are the hours a client pays for. Everything else a consultant does, from internal meetings to sales calls, is non-billable. Two ratios describe the split:

  • Utilization rate compares billable hours with the hours a consultant was available: working days minus holidays and leave, times the hours in a working day.
  • Billability compares billable hours with all hours actually tracked, so it shows how much of the recorded work can go on an invoice.

Unbilled capacity is the hours a consultant was available but did not bill, priced at the hourly rate. It is the number to watch when utilization drops.

Consulting Cockpit works this out for every consultant every month, from the hours they track, corrected for weekends, public holidays per country and approved leave. See utilization reporting, billable hours tracking and time tracking for consultants.

Billable Hours, Answered

What are billable hours?

Billable hours are the hours you can charge a client for: work done for that client under an agreed rate. Internal meetings, sales, training and admin are non-billable.

How do I calculate the utilization rate?

Divide billable hours by available hours. Available hours are the working days in the period minus holidays and leave, times the hours in a working day.

What is a good utilization rate for consultants?

Many consultancies aim for 70 to 80 percent. Above that there is little room for sales, training and internal work; well below it, capacity goes unbilled.

What is the difference between utilization and billability?

Utilization compares billable hours with the hours a consultant was available. Billability compares billable hours with all hours actually tracked.

Does Consulting Cockpit calculate this for me?

Yes. It tracks billable and non-billable time per client and reports utilization and billability per consultant per month, corrected for weekends, public holidays and approved leave.
