A conversion fee is a charge a company pays a staffing agency to convert a temporary or contract worker into a permanent employee, or to hire an agency-sourced contractor directly onto its own payroll. The fee compensates the agency for the cost and effort of sourcing, vetting, and placing that worker, essentially "buying out" the agency's stake in the ongoing relationship. It is most often calculated as a percentage of the worker's annual base salary, and it frequently decreases the longer the worker has already been on assignment, since the agency has by then recouped more of its investment through markup on billed hours. Conversion fees are common in temp-to-perm hiring arrangements and are sometimes referred to as a buyout or a temp-to-perm fee. Understanding these terms up front, before a contract begins, is essential to avoid surprise costs when you decide to bring a strong contingent worker onto your permanent team.
When you engage a temporary worker or contractor through a staffing agency, the agency retains a commercial interest in that placement. If you later decide to hire that person directly, you are removing the agency from the revenue stream it expected to earn through its ongoing markup on billed hours. The conversion fee is how the agency is compensated for that lost future income and for the original work of finding and vetting the candidate.
The mechanics typically follow a predictable sequence:
Because these terms are set inside the original staffing contract, the smartest time to negotiate a conversion fee is before the assignment starts, not when you are already attached to a specific person and have less leverage.
Most conversion fees are structured as a percentage of the worker's first-year annual base salary, commonly landing somewhere in the range of a standard direct-placement fee. A defining feature is that the fee usually declines on a sliding scale the longer the worker has been on assignment, because the agency recovers more of its investment through markup with each week billed.
Two common structures
| Time on Assignment | Illustrative Conversion Fee | Why It Changes |
|---|---|---|
| 0-3 months | Full percentage of salary | Agency has recovered little of its sourcing cost |
| 3-6 months | Reduced percentage | Markup earned to date offsets part of the fee |
| After a set threshold | Often waived entirely | Agency has been fully compensated through billing |
Always read the exact schedule in your staffing agreement, since the salary basis (base only versus total compensation) and the tenure thresholds vary widely between agencies.

Book a Demo A conversion fee is easy to confuse with other contingent-workforce charges, but each serves a different purpose in your contingent workforce spend.
Understanding where a conversion fee sits helps you evaluate the true total cost of workforce before committing to a temp-to-perm path, rather than discovering it as a surprise at conversion time.
Surprise conversion fees are a symptom of the traditional agency model, where the provider is incentivized to keep a worker classified as contingent for as long as possible. WorkGenius takes a different approach. As an AI-powered contingent workforce platform for US enterprises, we combine AI matching with expert human recruiters to deliver pre-vetted candidates typically within 48 hours, and we give you one platform to source, classify, onboard, manage, and pay talent.
Because WorkGenius supports direct sourcing and builds reusable talent pools, you reduce reliance on layered agency markup and gain real-time visibility into contingent spend. When a worker is the right long-term fit, our transparent model and integrated employer-of-record compliance make the path to a permanent or direct-hire relationship clear and predictable, so conversion terms never become a hidden cost. Explore our contingent workforce playbook to see how enterprises replace unpredictable agency fees with a single, accountable platform.
Conversion fees are most often calculated as a percentage of the worker's first-year annual base salary. The exact figure depends on your staffing agreement and, critically, on how long the worker has already been on assignment. Many agreements use a declining scale, so a conversion after several months costs far less than one in the first few weeks, and some fees are waived entirely once a defined tenure threshold is reached.
The fee compensates the agency for two things: the original cost of sourcing and vetting the candidate, and the future markup revenue it forgoes when you take the worker off its billing and onto your own payroll. From the agency's perspective, converting a worker ends an ongoing revenue stream, and the conversion fee is how that lost income is recovered in a single payment.
Yes. The best time to negotiate is before the assignment begins, while you still have leverage and are not attached to a specific person. You can push for a lower percentage, a shorter buyout period, or a clear point at which the fee drops to zero. Working with a transparent platform that supports direct sourcing can reduce or remove these fees altogether by lessening reliance on the traditional agency markup model.
They usually describe the same thing. "Buyout" is common industry shorthand for a conversion fee, especially when the amount declines over time as the agency recovers its investment. Both terms refer to the payment that lets you move an agency-sourced temporary worker or contractor into a permanent, direct-hire role.
It can. A conversion fee is not limited to temp-to-perm situations. If you want to hire an agency-sourced independent contractor directly onto your payroll, the agency may charge a conversion or buyout fee to compensate for having sourced and placed that person. Always check your staffing agreement for the specific triggers and amounts before making the move.
