Yield Ratio and Cost Per Hire Formula: A Practical Guide
Two formulas explain most of your desk economics: cost per hire tells you what a placement costs, and yield ratio tells you how many candidates it takes to get there. Here is how to calculate both, with worked examples for staffing agencies.
Written by: Saply Team
Cost per hire is total recruiting costs divided by the number of hires made in a period. Yield ratio is the percentage of candidates who move from one stage of the hiring process to the next. Together they answer the two questions every agency owner eventually asks: what does a placement actually cost us, and how many candidates do we have to touch to make one?
Most desks track time to fill obsessively and leave these two alone, which is backwards. Time to fill tells you how fast you moved. Cost per hire and yield ratio tell you whether the desk makes money and where the pipeline leaks. This guide gives you both formulas, worked examples with real numbers, and the mistakes that quietly break the math.
The cost per hire formula
The Society for Human Resource Management, which authored the ANSI cost per hire standard, defines it simply: add every internal and external recruiting cost for a period, then divide by the number of hires in that same period.
The formula is easy. The honest work is in the numerator, because “recruiting costs” is where agencies either overcount or, more often, forget the biggest line items. Internal costs are the ones you pay whether or not you fill the role. External costs are the ones triggered by the search itself.
| Internal recruiting costs | External recruiting costs |
|---|---|
| Recruiter and sourcer salaries (time on the role) | Job board and LinkedIn slot fees |
| Talent acquisition tooling: ATS, CRM, matching | Advertising and sponsored posts |
| Referral bonuses paid internally | Background checks and assessments |
| Onboarding and admin time | Agency or RPO fees (for internal teams) |
| Overheads allocated to the recruiting function | Events, job fairs, and travel |
For a staffing agency the framing shifts slightly: your “hire” is a placement, and the largest internal cost is recruiter time spent sourcing, screening, formatting, and submitting. That is exactly the cost that scales with volume and quietly decides whether a desk is profitable.
SHRM puts the average cost per hire at nearly $4,700. Treat that as a reference point, not a target. Agency placement economics differ from in-house hiring, but the number is useful for one thing: if your own figure is a small fraction of it, you are probably undercounting recruiter time.
A worked cost per hire example
Take a desk that made 5 placements last quarter. Internal costs: two recruiters at a blended 4,000 per month of loaded salary time attributed to sourcing and submission, over three months, is 24,000, plus 1,500 in ATS and tooling. External costs: 3,000 in job board and LinkedIn spend, plus 500 in assessments. Total is 29,000 across 5 placements.
Cost per hire is 29,000 divided by 5, which is 5,800 per placement. If your average placement fee is 8,000, the desk is profitable but thinner than it looks once you add non recruiting overhead. That single number changes how you price, how you staff, and which clients you keep. If you want to model fee against fully loaded cost before you take a role, our ROI calculator runs the same math on your inputs.
The yield ratio formula
Cost per hire tells you the price of a placement. Yield ratio tells you how many candidates it took to get there, one stage at a time. It is the percentage of candidates who advance from one step of the funnel to the next.
Yield ratio for a stage is candidates advancing to the next stage, divided by candidates entering the current stage, times 100. You calculate it per transition, and you can also calculate an overall applicant to hire yield across the whole funnel.
Read the funnel one transition at a time. Of 200 applications, 80 passed screening, a 40 percent yield. Of those 80, half were submitted to the client. Of the 40 submitted, 16 got an interview. Of those, 4 were placed. The overall applicant to hire yield is 4 divided by 200, which is 2 percent.
| Transition | Formula | Yield |
|---|---|---|
| Application to screen | 80 / 200 | 40% |
| Screen to submission | 40 / 80 | 50% |
| Submission to interview | 16 / 40 | 40% |
| Interview to placement | 4 / 16 | 25% |
| Overall applicant to hire | 4 / 200 | 2% |
The single most important ratio for an agency is submission to interview. It is the client’s verdict on your shortlist. A submission to interview yield below roughly 40 percent usually means you are sending volume instead of fit, and every rejected submission is recruiter time you already paid for. Track it per client, because the same recruiter can post a strong ratio with one hiring manager and a weak one with another.
How the two formulas explain each other
Yield ratio and cost per hire are the same story told from two ends. Every stage where your yield drops is a stage where you spent effort that produced nothing, and that wasted effort lands in the numerator of your cost per hire. Improve a weak yield and cost per hire falls without you touching a single price.
The lever most desks ignore: the submission stage. If your screen to submission yield is high but submission to interview is low, you are formatting and sending candidates who were never going to land. Fixing fit earlier costs nothing extra and lifts both metrics at once.
This is where the upstream workflow matters more than the reporting. The quality and consistency of what you submit is what moves the submission to interview yield, and that in turn moves cost per hire. Better candidate to role matching means recruiters submit fewer, stronger CVs instead of padding a shortlist to look busy. In Saply, parsing, tailoring, and matching run in one pass, so the shortlist a recruiter sends is ranked by fit rather than by whoever applied first. The honest limit: no tool improves a yield that is broken by a bad brief or an unrealistic client. Software sharpens the shortlist, it cannot fix a role nobody wants.
Where agencies get the math wrong
Three mistakes account for most bad numbers.
- Forgetting recruiter time. The biggest cost on a staffing desk is human hours, and it is the one line people leave out because it is not an invoice. A cost per hire built only from job board spend is fiction.
- Mismatched periods. Divide this quarter’s costs by this quarter’s hires. Counting costs for roles that will close next quarter inflates the number and hides the trend.
- Averaging across very different desks. A perm desk and a high volume temp desk have different yields and different costs by design. Blend them and both look wrong. Segment first.
Yield ratios fail the same way when the funnel stages are not defined consistently. If one recruiter logs “submitted” at CV send and another at client acknowledgement, the ratios are not comparable. Agree on stage definitions before you compare people. A shared recruitment KPI dashboard with fixed stage names is the cheapest way to keep everyone honest. For a fuller picture of whether your placements actually stick, pair these two metrics with quality of hire, which measures the outcome the client actually pays for.
Frequently asked questions
What is the cost per hire formula?
Cost per hire is total internal recruiting costs plus total external recruiting costs, divided by the number of hires made in the same period. Internal costs include recruiter time and tooling. External costs include job board fees, advertising, and assessments. For a staffing agency the largest internal cost is almost always recruiter hours spent sourcing and submitting.
How do you calculate yield ratio in recruiting?
Yield ratio for a stage is the number of candidates who advance to the next stage divided by the number who entered the current stage, multiplied by 100. Calculate it per transition, for example screen to submission or submission to interview, and calculate an overall applicant to hire yield by dividing final placements by total applications.
What is a good yield ratio for a staffing agency?
There is no universal figure because it depends on role type and channel, but submission to interview is the ratio that matters most for agencies, and below roughly 40 percent usually signals a fit problem rather than a volume problem. Track it per client and per recruiter rather than as a single blended number, since the same person can perform very differently across hiring managers.
What is the average cost per hire?
SHRM reports an average of nearly $4,700, though that figure reflects in-house hiring rather than agency placements. Use it as a sanity check, not a benchmark to hit: agency economics are driven by placement fee against fully loaded recruiter cost, so your own segmented number is far more useful than any industry average.
How are yield ratio and cost per hire related?
They measure the same pipeline from opposite ends. Low yield at any stage means effort that produced no placement, and that wasted effort inflates cost per hire. Improving a weak yield, especially at the submission stage, lowers cost per hire without changing any prices, which is why the two should always be read together.
