This is the unit-economics view a CFO should see before scaling hiring: how the three models actually compare on total cost per hire, and where the break-even sits.
The Three Models on One Page
- External agency: pay a percentage of salary per placement. No fixed cost, highest per-hire cost, least control.
- Embedded recruiter: a dedicated recruiter (or team) working inside your org for a monthly fee, usually via RPO. Moderate fixed cost, low cost per hire at volume.
- In-house team: salaried recruiters you employ. Highest fixed cost, most control, slowest to scale up or down.
The Cost Components Nobody Lines Up
Comparing only the agency fee against a recruiter salary misses the real picture. The honest comparison includes fixed cost (salaries, tools, management), variable cost per hire, ramp time, and the cost of unfilled roles. An in-house hire who takes three months to become productive is a cost, even though it never appears on an invoice.
Cost Per Hire Compared
| External agency | Embedded recruiter | In-house team | |
|---|---|---|---|
| Fixed cost | None | Monthly fee | Salaries plus tools |
| Cost per hire | Highest | Low at volume | Lowest at high volume |
| Control / brand | Low | High | Highest |
| Ramp time | Immediate | 1 to 2 weeks | 1 to 3 months |
| Scales down easily | Yes | Yes | No |
| Best at | Low or spiky volume | Steady, scaling volume | High, sustained volume |
The Break-Even Math
Take a worked example. An agency at 20% of a ₹40L salary costs ₹8L per hire. At 10 hires a year that is ₹80L, with no fixed cost. An embedded recruiter on a monthly retainer might cost ₹1.2Cr a year but deliver 30 hires, a far lower cost per hire once volume is there. Below roughly 15 hires a year the agency is cheaper; above it, embedded wins and the gap widens with volume.
The other variable is duration. For a one-off hiring spike, an agency avoids the fixed commitment. For a sustained scaling phase, embedded or in-house amortizes the fixed cost across many hires.

Book a Discovery Call →Embedded hiring changes the unit economics because the cost is decoupled from salary and tied to capacity instead. For a company scaling steadily, that turns hiring from a variable, unpredictable line into a fixed, forecastable one. Our logistics engineering RPO build shows the model at scale, and the RPO and embedded hiring practice exists to run exactly this.
