What is the payroll expense ratio?

Payroll expense ratio measures total payroll costs as a percentage of revenue, indicating how much of each revenue dollar goes to employee compensation. In professional services, this is typically the largest expense category. For professional service firm owners, tracking payroll expense ratio against industry benchmarks reveals whether staffing costs are in line with profitable firms.

Why it matters for professional service firms

Professional service firms are people businesses. Payroll is usually 50% to 70% of revenue. If yours is higher, you are either undercharging, overstaffing, or under-utilizing. If lower, you might be burning out your team. This ratio is a vital sign for firm health.

Real-world example

Jennifer's annual revenue: $1.8 million. Total payroll (including owner salary and burden): $1.1 million. Payroll expense ratio: 61%. Industry benchmark for consulting: 55% to 65%. She was in range but toward the high end. Analysis revealed two underperforming staff members with low utilization dragging down the ratio. Performance management improved their utilization, and the ratio dropped to 57%.
