What is gross profit per hour?

Gross profit per hour measures the profit contribution from each hour of billable work, calculated as the billing rate minus the direct cost per hour. For professional service firms, this metric reveals the value generated per hour of work, enabling comparisons across service lines, project types, and individual consultants. Higher gross profit per hour indicates more profitable work.

Key characteristics

• Billing rate minus direct hourly cost

• Measures profit contribution per hour worked

• Enables comparison across work types

• Useful for pricing and staffing decisions

• Should be tracked at the service and consultant levels

• Different from gross margin percentage

Why it matters for professional service firms

Hours are the fundamental unit of production for professional service firms. Understanding profit per hour helps prioritize work types and inform pricing. A service line with $75 gross profit per hour generates twice the value of one with $38, regardless of utilization. Professional service firms should track gross profit per hour by service line to understand where hours create the most value and price accordingly.

Real-world example

Marcus's firm assumed all billable hours were equally valuable. Gross profit per hour analysis: Service A billed at $175, direct cost $72, gross profit $103 per hour. Service B is billed at $145; direct cost is $85; gross profit is $60 per hour. Service C is billed at $200; direct cost is $110; gross profit is $90 per hour. An hour of Service A work generated 72% more value than Service B. Strategic implications: grow Service A, improve Service B efficiency or pricing, and ensure higher direct costs justify Service C projects. Resource allocation shifted toward higher profit per hour of work.
