AI Hiring ROI: A Worksheet for Capacity, Cash Savings and Margin

AI hiring ROI needs a defined baseline, a complete cost model and a clear distinction between time released and money saved. This article provides worked examples you can reproduce. All figures below are illustrative assumptions, not customer results or Skill Society prices.

Start with one role type and the screening work you expect to change. A shorter first screen does not automatically reduce total time-to-hire, improve retention or create additional placements.

Define the measures before calculating ROI

Measure	Calculation	What it establishes
Hours released	Baseline human hours minus pilot human hours for comparable volume	Capacity available for other work
Capacity value	Hours released × fully loaded hourly cost	An economic estimate; salary may still be paid
Cash saving	Actual avoided expense attributable to the change	A reduction in spending, such as approved overtime no longer needed
Additional contribution	Incremental revenue minus incremental delivery costs	Money available before fixed overhead and tax; not revenue alone
Net financial ROI	(Attributable financial benefit − total investment) ÷ total investment × 100	Return for the stated period and assumptions

Include software, setup, integration, training, reviewer time and ongoing administration in the relevant cost categories. Count each item once. If reviewer time has already been subtracted when calculating released hours, do not subtract it again as the same labour expense.

Worked example 1: released screening capacity

Assume a hiring team processes 100 comparable campaigns over a year. Manual screening takes 8 hours per campaign. The pilot workflow takes 3 hours of human work per campaign, including setup allocated to that campaign, review, follow-up and exceptions.

• Baseline: 100 × 8 = 800 hours.
• Pilot: 100 × 3 = 300 hours.
• Released capacity: 800 − 300 = 500 hours.
• At an assumed fully loaded cost of AUD 60/hour: 500 × 60 = AUD 30,000 of capacity value.

If the team spends an illustrative AUD 12,000 on software and external implementation, its net capacity value is AUD 18,000. The corresponding economic return is (30,000 − 12,000) ÷ 12,000 × 100 = 150%.

That is a capacity-based estimate. If staffing costs do not fall and the released time creates no measured additional contribution, it is not AUD 30,000 of cash savings. Report the 500 hours and explain how the team will use them.

Worked example 2: actual avoided expenditure

Assume a business had approved AUD 24,000 in temporary screening support for the measurement period. A pilot demonstrates that the support is no longer needed for the same workload and review standard. Software, external setup and incremental paid training cost AUD 16,000 in total.

• Avoided expenditure: AUD 24,000.
• Net benefit: 24,000 − 16,000 = AUD 8,000.
• Net financial ROI: 8,000 ÷ 16,000 × 100 = 50%.

Keep the approved budget, comparable workload and cancellation of that expense as evidence. Do not also count the temporary staff's hours as a second saving. If the support would never have been purchased, the avoided-spend claim does not hold.

Worked example 3: an agency's additional placements

Assume an agency attributes 20 additional placements to newly available delivery capacity over a year. Each generates AUD 8,000 in fees and AUD 5,600 in incremental delivery costs, including commissions and an allowance for replacements.

• Additional revenue: 20 × 8,000 = AUD 160,000.
• Additional delivery costs: 20 × 5,600 = AUD 112,000.
• Additional contribution: 160,000 − 112,000 = AUD 48,000.
• Separate software and setup investment: AUD 20,000.
• Net contribution after that investment: 48,000 − 20,000 = AUD 28,000.
• Illustrative net ROI: 28,000 ÷ 20,000 × 100 = 140%.

AUD 160,000 is revenue, not profit. This example excludes changes in fixed overhead and tax. Attribution also matters: additional placements caused by a new client, stronger demand or extra recruiters cannot all be credited to screening software.

A worksheet for your own pilot

Use the same period and currency throughout.

Input	Baseline	Pilot	Evidence to retain
Comparable applications/campaigns	Your count	Your count	Role type, applicant volume and requirements
Human screening and review hours	Your total	Your total	Time records, including exceptions
Paid external support/overtime	Your spend	Your spend	Invoices or payroll records
Software and implementation	Existing cost	Incremental cost	Current quote and actual charges
Completed placements/hires	Your count	Your count	Start dates and agreed outcome definition
Incremental contribution	If relevant	If relevant	Fees, commissions, delivery costs and attribution
Candidate completion and feedback	Your results	Your results	Counts, denominators and collection method

Do not use a broad percentage reduction as a substitute for these inputs. Include a low case where applicant volume or completion is lower than expected, and a high-cost case with more review and integration work.

Check the break-even point

For the capacity example, AUD 12,000 ÷ AUD 60/hour = 200 released hours to match the investment in economic value. That still does not establish cash payback.

For the agency example, contribution before the software investment is AUD 2,400 per additional placement. AUD 20,000 ÷ AUD 2,400 = 8.33, so 9 attributable additional placements would exceed the investment under those assumptions.

What evidence should a customer case study provide?

Look for the named customer, role, period, sample size, baseline, included costs and the precise stage measured. A reported reduction in qualification-and-interview time is different from time to accepted offer. Annualised projections are different from observed results.

These illustrative returns are not typical results or guarantees.
