Say you hired a sales rep last quarter at $65,000, and your recruitment agency invoiced you $13,000. You paid it, onboarded the hire and moved on.
Here’s the question most companies never ask about recruitment agency fees: what did that $13,000 actually buy?
It didn’t buy a guarantee that the hire would work out, and it rarely buys a look at how the candidate compares to your best people. In most cases, you paid for a shortlist: a filtered stack of resumes, often from job boards you already have access to, screened by a recruiter who works with many other clients and has no financial stake in whether your new employee stays past day 90.
For companies that hire often, agency fees can become one of the biggest lines in the hiring budget, and one of the least questioned. Here’s how the model works.
How recruitment agency fees work
The most common structure is contingency: the agency submits candidates, and you pay only if you hire one. The fee is usually a percentage of the new hire’s first year’s base salary, and the rate depends on the agency, the role and what you negotiate.
A second structure is the retainer model. You pay part of the fee upfront to engage the agency exclusively, with the balance due at placement. Retained searches are more common for senior and executive roles.
Some agencies also bill by the hour for project work. It’s less common, but it gives you some visibility into where the recruiter’s time goes.
Most companies hiring in volume for retail, call centers or sales work on contingency. It feels safe: no placement, no fee. But the incentive structure that makes contingency feel safe can also work against you.
What the fee covers (and what it doesn’t)
When you pay a contingency fee, you’re paying the agency to source, screen and present candidates. In practice, that usually includes:
- Sourcing: searching LinkedIn, Indeed and niche job boards. Your internal team may already have access to many of the same sources.
- Resume screening and a shortlist: the recruiter filters applications and presents a curated list. This saves internal time, and it’s where most of the work goes.
- Interview coordination: scheduling, candidate communication and offer logistics.
Here’s what contingency arrangements often don’t include:
- Fit with your top performers: agencies usually match candidates to the job description. They don’t typically compare a candidate’s profile to the people who already succeed in that role at your company.
- Accountability after the hire: once the hire is made and the invoice is paid, the agency’s financial incentive ends. If the hire leaves in month 4, you carry the cost of filling the seat again.
Some agencies offer replacement guarantees. Read the terms closely: they often cover a short window, and using one means restarting the search with the same agency that produced the first hire.
The structural misalignment in contingency fees
The contingency model, the most common structure for recruitment agency fees, has a basic design problem: the agency gets paid when you hire, not when the hire works out.
That rewards placement speed. Present enough viable candidates, get one across the finish line and collect the fee. Volume is rational from the agency’s side, and quality is harder to prioritize when there’s no financial stake in it.
The misalignment can show up in a few ways:
- Split attention: agencies work for several clients at once. A recruiter juggling roles across many companies has limited time for each one.
- Shared candidates: a strong candidate may be presented to your role and to other clients at the same time, because that raises the recruiter’s odds of a placement somewhere.
- Little visibility: many agencies don’t share their sourcing methods, screening criteria or why candidates were rejected. You get a shortlist with no view into how it was built.
For a single executive hire, those tradeoffs may be acceptable. At 40, 100 or 500 hires a year, they add up.
The math at volume
Take a hypothetical company in retail or call centers that makes 120 hires a year. Say the average salary across those roles is $55,000 and the agency charges 20%.
- Fee per hire: $11,000
- Annual agency spend: $1.32 million
For context, SHRM’s 2025 benchmarking data puts the average cost per hire at $5,475 for nonexecutive roles, counting all recruiting costs. In this example, the agency fee alone is about twice that average, on every hire. For more on how that benchmark is built, see our breakdown of the SHRM average cost per hire.
What to look for instead
The alternative to a black box starts with alignment. Judge a provider not only on whether they fill roles, but on whether the people they place perform and stay. Ask how candidates are sourced, how they’re screened and what you’ll see along the way. These questions to ask a staffing agency are a good place to start.
For volume hiring, Recruiting as a Service (RaaS) is one alternative. Workwolf® sources candidates, filters them with AI, phone screens them with its recruiters and books the best fits into your calendar, so you only meet the finalists and make the hire. Workwolf® runs on its own AI engine, Packfinder. It screens and ranks every applicant against the profile of each client’s top performers, and it gets more precise with every placement. Clients get transparency into how candidates were sourced and scored.
The traditional agency model has its place. For a single executive search where network access matters, retained search can make sense. But for high volume roles, where costs compound and retention is the real metric, the fee structure most companies default to is worth questioning.
The question you should be asking
Recruitment agency fees aren’t unreasonable in themselves. Placing candidates is real work. The problem is the structure: a model that charges a premium, offers little visibility into the process and collects the full fee whether the hire succeeds or not.
For companies making dozens or hundreds of hires a year, that’s not a minor inefficiency. It’s a cost built into the hiring function, and it repeats every quarter.
Start by understanding what you’re paying for. Then ask whether the model fits your volume, your risk tolerance and your retention goals. If you need to make that case to finance, our guide to building a business case for outside recruiting walks through it step by step.
