ROI Calculator: AI Interviews vs Traditional Recruiting Costs

The True Cost of Traditional Recruiting

Most companies radically underestimate hiring costs. The "cost per hire" metric captures recruiter salary and job postings—but misses the iceberg beneath.

Hidden costs:

  • Hiring manager time in interviews (opportunity cost)
  • Poor quality hires turning over in <1 year (replacement costs)
  • Productivity loss from unfilled positions
  • Overtime for existing team covering gaps
  • Rushed bad hires from pressure to fill quickly

The actual cost per hire averages $15,750 when you include everything (SHRM, 2026).

For a 100-hire/year company, that's $1.575M annually just in recruitment costs.

AI Interview Economics

Voice AI dramatically changes the equation:

Cost structure:

  • Platform fee: $400-800/month (depending on volume)
  • Per-interview cost: $0 (unlimited in ARIA's model)
  • Implementation: 1-2 days setup (mostly configuring questions)

What you save:

  1. Recruiter time: 75-85% reduction in screening hours
  2. Time-to-fill: 60-80% faster means less productivity loss
  3. Quality-of-hire: 15-25% improvement = lower turnover costs
  4. Candidate experience: Higher offer acceptance rates

Common Objections

"Our company is too small for AI."

False economy.

Even 10 hires/year at $15K each = $150K spend. AI costs $4-8K/year. ROI works at ANY scale.

"AI is too expensive."

Compare to alternatives:

  • Additional recruiter: $80-120K/year + benefits
  • Staffing agency: 20-30% of salary per hire
  • Bad hire: $50-200K in turnover costs

AI is the cheapest option at scale.

"Setup is complicated."

Modern platforms = plug-and-play:

  • ARIA setup: 2-4 hours
  • ATS integration: Pre-built connectors
  • Training: 30-minute walkthrough

Faster than onboarding a new recruiter.
