Enter chargeable and total hours (or use available hours as the utilization denominator), plus optional standard and net fees to see utilization and realization percentages.
Utilization and realization formulas vary by firm; this tool shows the maths for the basis you select. It does not replace your practice management system or MAP survey benchmarks.
Hours
Billable hours ÷ total hours worked × 100.
Fees (realization)
Realization = net fees ÷ standard fees × 100 when both are entered. Journal of Accountancy: “Realization can be calculated by taking the net hours billed divided by gross billable hours accrued or, more typically, the net fees billed divided by gross fees accrued.”
