ROI Framework

Measuring HR AI value.

Recruitment ROI

Cost per Hire Reduction:

Before AI:
- Recruiter time: 40 hours × $50 = $2,000
- Job boards: $500
- Screening tools: $200
Total: $2,700

After AI:
- Recruiter time: 15 hours × $50 = $750
- AI screening: $100
- Job boards: $500
Total: $1,350

Savings per hire: $1,350 (50%)

Time to Fill Reduction:

25% faster hiring × 50 hires/year × $500/day vacancy cost × 10 day reduction
= $250,000 annual savings

Onboarding ROI

HR Time Savings:

30% reduction in questions × 100 new hires × 5 hours saved
= 500 hours × $50 = $25,000

Faster Productivity:

50% faster ramp × 100 new hires × $5,000 value/month
= $250,000 additional value

Total HR AI ROI

Example Organization (500 employees, 100 hires/year):

Investment: $50,000/year ROI: 650%
