Agency vs In-House Recruiter ROI

Agency or in-house and how this is calculated

Recruiting agencies charge a fee for each hire, usually a percentage of the new hire's first-year salary, so the more you hire, the more you pay. An in-house recruiter is a fixed annual cost that does not rise much with volume. This tool compares the two: the agency route is your hires times the fee, and the in-house route is the recruiter's fully loaded cost. The gap is your annual saving, and the crossover point is where in-house starts to win.

What goes into each route

The agency route is hires per year times the average starting salary times the agency fee percent. Standard contingency fees run from 15 to 25 percent, with 20 percent typical and executive roles higher. The in-house route adds up the recruiter's base salary, benefits, and the tools and job boards they need. If your volume is higher than one recruiter can fill, the overflow is priced at the agency rate so the comparison stays fair.

Reading the break-even

Break-even is the number of hires per year at which an in-house recruiter costs the same as paying agency fees. Below it, agencies are usually cheaper because you only pay when you hire. Above it, the fixed cost of a recruiter is spread across enough hires to beat the per-hire fees. That crossover is the single most useful number for deciding when to bring recruiting in-house.

What the dollars miss

Cost is only part of the decision. Agencies give you speed, a ready network, and a guarantee if a hire does not work out, with no fixed payroll. An in-house recruiter gives you a consistent candidate experience, a stronger employer brand, and a talent pipeline that compounds over time. Weigh those alongside the numbers.

What agency fee should I use?

Contingency fees are commonly 15 to 25 percent of first-year salary, with 20 percent the usual benchmark. Entry-level roles run lower, around 10 to 15 percent, and executive or retained searches run higher, often 25 to 35 percent. Use the rate your agencies charge.

How many hires justify an in-house recruiter?

It depends on your salaries and fee. The break-even here gives you the number for your inputs. As a rough rule, steady volume in the high single digits or more per year often favors in-house, while low or unpredictable volume favors agencies.

Should I include hidden agency costs?

This tool counts the agency fee only. Your team still reviews candidates and runs interviews either way, so those costs are roughly common to both routes. If you want, add them to the recruiter's tool budget to see the effect.

Is this financial advice?

No. It is a planning estimate based on common fee benchmarks. Confirm fees, salaries, and the right model for your situation.
