AI Interviewer ROI Calculator: Model Your Cost-per-Hire Savings (2026)
This calculator lets you model the cost-per-hire reduction from adopting AI interviewer tooling, using SHRM's $4,700 average cost-per-hire and real time-to-hire math. No email required. We show the formula. Last verified April 2026.
Your Organisation
AI Interviewer Assumptions
Conservative: 10-15%. With good change management: 20-25%. Vendor claims: 30-40% (apply scepticism).
Results
The Formula (verify in your spreadsheet)
In-scope hires = 300 x 60% = 180
Gross savings = 180 x $4,700 x 20% = $169,200
Net savings = $169,200 - $40,000 = $129,200
Payback = $40,000 / ($169,200 / 12) = 2.8 months
Honesty callout
These savings are achievable if you also implement good change management and structured interview design. Without recruiter adoption and process discipline, AI interviewer tooling typically reduces cost-per-hire by 5-10%, not 20-25%. See the implementation guide for the change management playbook.
