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. It defaults to SHRM's last openly-published figure, $4,129 average cost-per-hire (Human Capital Benchmarking Report, fiscal year 2015); current-market costs run higher, so set your own. No email required. We show the formula. Last verified June 2026.

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 $4,129 x 20% = $148,644
Net savings = $148,644 - $40,000 = $108,644
Payback = $40,000 / ($148,644 / 12) = 3.2 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.
