How this is calculated

Utilization = billable hours / available hours x 100. Available hours normally means working hours minus holiday and known time off, not a flat 40 a week.

Frequently asked
Should available hours be 40 a week?

Only if nobody takes holiday. Most teams subtract holiday, public holidays and known training, which raises utilization for the same billable hours and gives a number you can actually plan against.

Is 100 percent utilization good?

No. It means there is no slack for sickness, estimation error or the next sales cycle, so the first surprise slips a client date. Sustained utilization above roughly 85 percent is a scheduling risk rather than an achievement.

How does this differ from billable utilization versus capacity?

Utilization looks backward at hours already logged. Capacity looks forward at hours still unassigned. Planning needs both, which is why a capacity heatmap across people and weeks is more useful than a single percentage.
