Source: A contract professional costs a client EUR 81.02 per hour on average (VvDN MarktMonitor Q2 2026). The contract staffing firm's margin commonly runs at 20-30% of that rate, or EUR 16 to EUR 24 per hour. At roughly 1,700 billable hours per year that is EUR 27,000 to EUR 41,000 gross margin per year, per professional. Contract staffing assignments often run longer than a year.
This is a model, not a realised result. Adjust the assumptions to your own margins and placement rate.
