Quality of hire by channel.
Direct CPH is only half the picture. The channel that delivered the hire matters for quality, retention, and ramp time. JobVite Benchmark Report, the 2025 SHRM Benchmarking Report, and Greenhouse and Lever ATS provider data converge on the following ranking:
- Internal promotion: highest 12-month retention (85 to 95%), shortest ramp time, lowest bad-hire rate.
- Employee referral: 75 to 90% 12-month retention, fast ramp, high cultural fit.
- Retained search: 80 to 90% 12-month retention at senior level due to research depth and reference rigor.
- LinkedIn direct sourcing: 65 to 80% 12-month retention; varies by recruiter and message quality.
- Contingency agency: 60 to 75% 12-month retention; varies widely by agency partner.
- Job board inbound: 55 to 70% 12-month retention; lowest in the cohort.
The implication: investment in employee referral programmes and internal promotion ladders has the best ROI of any hiring-cost lever because it improves both direct cost and quality.
Best channel mix by role type.
Channel choice is role-specific. The same company may run referral-first for engineering and retained search for executive in the same quarter.

Why employee referral is the most-recommended hiring lever.
A well-run referral programme typically captures 30 to 45 percent of total hires at $2,500 average CPH including bonus payout. Replacing those hires with a 25-30 percent agency stack would cost $20,000+ per hire, or roughly $500K to $1M+ in agency spend at a 100-hire annual programme. Referral programme operating cost (bonus payouts + small admin overhead) at the same volume runs $75K to $150K.
Net savings: $400K to $900K per year at moderate scale. Plus the retention and quality uplift. Plus reduced recruiter screening time per hire. The investment to run the programme well is modest: a designated programme owner, clear payout policy, fast bonus payment turnaround, and quarterly internal promotion of referral asks. The hard part is sustaining it; programmes that launch with fanfare and then go silent within 6 months under-deliver consistently.

Cost per hire by channel, answered.
Which sourcing channel has the lowest cost per hire?
Internal promotion has the lowest direct CPH ($0 to $1,000 per hire, mostly admin and announcement cost) but is limited by available internal pool. Employee referral runs $1,800 to $3,500 per hire including the referral bonus payout, with a high yield rate (60 to 70 percent of qualified referrals progress to offer per Greenhouse and Lever benchmark data). Job boards (Indeed, ZipRecruiter, LinkedIn job posts) run $1,500 to $5,000 per hire depending on role seniority and posting strategy. Agency channels (contingency 15-25% of base) are the most expensive at $15,000 to $40,000+ per hire.
Why is employee referral cheaper than every other channel?
Three factors compound. First, no sourcing time investment; the referring employee surfaces the candidate. Second, no agency fee or job-board spend. Third, qualification rate is dramatically higher (60 to 70 percent of referrals make it to qualified interview vs 10 to 25 percent for inbound from job boards), which reduces recruiter screening time. The referral bonus payout ($1,000 to $5,000 typical) is the only meaningful direct cost line, and it lands in the employee's pocket rather than a vendor's bank account. Quality of hire is also higher per JobVite and SHRM benchmarks because referrers self-select against poor-fit candidates.
When does LinkedIn Recruiter pay back?
LinkedIn Recruiter Corporate seat lists around $10,000 to $14,000 per year per seat. The seat pays back when the recruiter produces enough sourced-and-hired candidates through LinkedIn to beat the cost of equivalent agency placements. Typical recruiter productivity on LinkedIn Recruiter is 6 to 12 sourced hires per year at $5,000 to $10,000 fully-loaded sourced cost per hire (including recruiter time at loaded rate). That beats 20% contingency on $100K+ hires after the second placement. For lower-volume or junior-role hiring, LinkedIn Recruiter typically does not pay back on a per-seat basis.
What is the typical channel mix for a tech company?
Greenhouse and Lever benchmark data across thousands of growth-stage tech customers shows: employee referral 25 to 40 percent of hires, LinkedIn or direct sourcing 20 to 30 percent, job board inbound 10 to 20 percent, agency 5 to 15 percent (concentrated on senior or specialist), internal promotion 5 to 10 percent, university / early-career programmes 0 to 10 percent. The mix shifts heavily for high-volume retail and hospitality (job board and walk-in dominate, agency rare) and for senior banking and consulting (retained and referral dominate, job board near-zero).
Does channel choice affect quality of hire?
Yes per multiple benchmark sources. Employee referral and internal promotion produce the highest 1-year retention rates (typically 75 to 90 percent retention at 12 months vs 60 to 75 percent for job board hires per JobVite Benchmark Report). Agency channel hires have intermediate retention. Internal-promotion hires also have the shortest ramp time. The implication: cheapest channel by direct CPH is also typically the highest quality, which is why employee-referral programmes are the single most-recommended hiring lever.
