What is a productivity ratio?

Productivity ratio measures billable hours as a percentage of total available working hours, indicating how much of staff time generates revenue versus administrative, business development, or other non-billable activities. It is similar to utilization but may include all staff, not just billable professionals. For professional service firm owners, the productivity ratio reveals the capacity for additional revenue without adding headcount.

Key characteristics

• Billable/total hours

• Indicates revenue capacity

• Target varies by role

• Administrative time included

• Room for improvement often exists

• Weekly or monthly tracking

Why it matters for professional service firms

Where does time actually go? A consultant with 50% productivity has 50% of their time on non-billable work. Some non-billable time is necessary: training, administration, and business development. But excess non-billable time is lost revenue. Tracking productivity identifies where time leaks and how to recapture it.

Real-world example

Marcus tracked productivity across his 6-person firm. Results: senior consultants 68% and 72%, mid-level 65% and 58%, junior 55% and 48%. The 48% junior concerned him. Analysis revealed excessive internal meeting attendance and administrative tasks. He reassigned admin work and limited meetings. Junior productivity rose to 62%—additional billable hours: roughly 300 annually, worth $45,000 at her billing rate.
