Most assessment platforms don't publish a per-candidate rate. What they publish (if anything) is a starting price, an annual subscription tier, or a prompt to request a quote. That opacity makes it genuinely difficult for HR leaders and CHROs to compare costs across platforms like Selection Lab, Harver, Talogy, and HireVue before entering a sales process.
This article builds an auditable methodology for estimating effective cost per candidate across different hiring volumes, applies it to worked scenarios at 500, 5,000, and 25,000+ applicants per year, and places those estimates alongside third-party starting-price benchmarks for Harver, HireVue, and Talogy. The goal is a framework you can reuse with actual quote data from any vendor.
"Cost per candidate" sounds simple. In practice, it depends on how you define the denominator and which cost components you include.
For this article, the denominator is assessed candidates per year (applicants who completed at least one assessment stage). The formula is:
Effective cost per candidate = (Annual subscription fee + variable assessment spend + prorated onboarding) / assessed candidates per year
The key variables are:
Two pricing mechanics are modeled throughout:
Competitor figures in this article come from third-party software review sources (GetApp Canada, SoftwareAdvice GB, Sova Assessment blog, and similar) and are used only to compute an implied effective cost per candidate at the stated scenario volume. They are not official published rate cards.
Selection Lab's public pricing page (selectionlab.com/pricing-form) contains no numeric tiers, no per-candidate rates, and no published price bands. The page routes buyers to a custom quote workflow. That's standard practice for a platform that sells modular, role-based assessment bundles configurable by assessment mix, ATS integration, and contract length.

Quote checklist to make the math defensible. Before modeling your own $/candidate, request these six data points from any vendor:
With those six numbers, the formula above produces a defensible estimate.
Assumptions:
Sub-scenario A1 (low overage): Subscription covers 400+ candidates; no significant overage.
Cost component Amount Annual subscription [S] Variable overage (0 candidates above included) $0 Prorated onboarding $1,000 Total annual cost [S] + $1,000 Assessed candidates 375 Implied effective cost per candidate ([S] + $1,000) / 375At a hypothetical subscription of $6,000/year, that produces an implied $18.67/candidate. At $9,000/year, it's $26.67/candidate. Replace [S] with your quoted figure.
Sub-scenario A2 (overage applies): Subscription includes 250 candidates; 125 candidates at an overage rate of, say, $15/candidate.
Cost component Amount Annual subscription [S] Overage (125 × $15) $1,875 Prorated onboarding $1,000 Total annual cost [S] + $2,875 Implied effective cost per candidate ([S] + $2,875) / 375At $6,000/year subscription, that's approximately $23.67/candidate.
Assumptions: same assessment mix; completion rate 75% = 3,750 assessed candidates; onboarding $5,000 amortized over 24 months = $2,500/year.
The key dynamic at this volume is that a fixed annual subscription fee is spread across far more candidates, so the implied per-candidate cost drops materially even if overage applies to a portion of volume.
Cost component Amount Annual subscription [S] Overage (assume 750 candidates above included volume at $10/candidate) $7,500 Prorated onboarding $2,500 Total annual cost [S] + $10,000 Assessed candidates 3,750 Implied effective cost per candidate ([S] + $10,000) / 3,750At a subscription of $20,000/year, that's approximately $8.00/candidate. Subscription-dominated pricing rewards volume: a $6/candidate improvement compared to Scenario A is common as fixed costs dilute across a larger base.
The practical breakeven question is: at what assessed volume does paying overage per candidate become cheaper than upgrading to a higher subscription tier? Request both figures during the quote process and run the comparison directly.
Assumptions: 25,000 applicants; completion rate 70% (17,500 assessed) and 90% (22,500 assessed); onboarding $15,000 amortized over 24 months = $7,500/year.
Sensitivity to completion rate matters at this scale:
Completion rate Assessed candidates Implied cost/candidate (at $60,000/year total spend) 70% 17,500 $3.43 90% 22,500 $2.67A 20-percentage-point difference in completion rate shifts implied cost per candidate by roughly $0.76 at a $60,000 total spend level. For enterprise programs where candidate dropout is a known risk, Selection Lab's reported 27% reduction in drop-offs (March 2025, Selection Lab Main Deck 2026) has a direct effect on implied cost per candidate: fewer incomplete assessments mean the fixed spend is distributed across more completions, reducing $/candidate.
At enterprise volumes, Harver and HireVue operate exclusively on custom annual contracts. Use only starting-benchmark figures for comparison, not implied per-candidate math from published rate cards that don't exist.
The table below uses third-party starting-price benchmarks as inputs. All figures in the "implied effective $/candidate" column are illustrative estimates based on stated starting prices divided by a fixed assumed volume. They are not published rate cards.

Implementation, integration complexity, and assessment mix can shift true effective cost significantly upward for any platform.
Volume predictability is the first filter. If your hiring volume is stable year-over-year, a subscription model with included volume offers budget certainty. If volume fluctuates, a per-candidate or credit model (like Talogy's standard tier) may be more economical in low-volume years, but scales less favorably at high volume.
Assessment depth is the second filter. A platform that covers the full selection funnel from intake through structured interview guide (as Selection Lab does) may carry a higher per-candidate cost than a single-stage test tool, but the relevant comparison is total recruitment cost, not assessment cost alone. Selection Lab reports 15 minutes saved per applicant (December 2025) and 21% lower early turnover in the first six months (January 2024). Those outcomes reduce post-hire costs that don't appear in a platform invoice.
