CFOs don't approve HR tech based on vibes—they need numbers
"We should automate recruiting" isn't a compelling business case. But "We'll save $890K annually while improving quality of hire 28%" gets budgets approved. In this guide, you'll learn exactly how to calculate recruitment automation ROI using proven financial frameworks. We'll cover every cost (obvious and hidden) and every benefit (quantifiable and soft). By the end, you'll have a bulletproof business case.
The ROI Formula (It's Simpler Than You Think)
ROI boils down to one question: Do the benefits exceed the costs? Here's the formula we'll use:
ROI Formula
Example Result:
($1,200,000 - $300,000) / $300,000 = 300% ROI
Payback Period:
$300,000 / $1,200,000 annually = 3 months
Simple in theory. The challenge is accurately calculating both sides of the equation. Let's break it down.
Part 1: Calculating Annual Costs (The Easy Part)
Recruitment automation costs are straightforward and predictable. Most vendors use transparent SaaS pricing.
| Cost Category | Typical Range | Notes |
|---|---|---|
| Platform Subscription | $15K - $150K/year | Varies by company size and hiring volume |
| Implementation/Setup | $5K - $25K (one-time) | Integration, data migration, workflow config |
| Training | $2K - $10K (one-time) | Recruiter and hiring manager onboarding |
| Ongoing Support/Success | Usually included | Premium support may cost 10-15% extra |
| ATS Integration Fees | $0 - $5K/year | Depends on existing tech stack |
Example: 200-Person Company, 60 Hires/Year
Part 2: Calculating Annual Benefits (Where the Magic Happens)
This is where most business cases fall apart. Benefits are harder to quantify but exponentially larger than costs. Let's break down every benefit category with real formulas.
Recruiter Time Savings
Automation eliminates manual screening, scheduling, and follow-ups. This is the most obvious and quantifiable benefit.
Calculation Formula:
Hours saved per hire = 12 hours (industry average)
Annual hires × hours saved = total hours saved
Total hours × hourly cost = annual savings
Example Calculation:
• 60 hires/year × 12 hours saved = 720 hours saved
• Average recruiter cost: $75/hour (loaded cost)
• 720 hours × $75 = $54,000 annual savings
Faster Time-to-Fill
Every day a role sits vacant costs money in lost productivity and opportunity costs.
Calculation Formula:
Days reduced × annual hires = total days saved
Average role salary / 365 = cost per vacant day
Total days saved × cost per day = annual savings
Example Calculation:
• Before automation: 45 days average time-to-fill
• After automation: 28 days average time-to-fill
• 17 days saved per hire × 60 hires = 1,020 days saved
• Average role salary: $85,000 / 365 = $233/day
• 1,020 days × $233 = $237,660 annual savings
Improved Quality of Hire
Better hires = higher performance = more revenue. This is the biggest benefit but hardest to quantify.
Conservative Approach:
Better hires perform 15-25% better (McKinsey research)
Use 10% improvement (conservative)
Annual hires × avg salary × 10% = value created
Example Calculation:
• 60 hires/year × $85,000 avg salary = $5.1M total comp
• 10% performance improvement = $510K incremental value
• Conservative capture rate: 25% (accounting for ramp time, attrition)
• $510K × 25% = $127,500 annual value
Reduced Turnover & Bad Hires
Better screening reduces mis-hires. Replacing a bad hire costs 50-200% of salary.
Calculation Formula:
Bad hire rate improvement × annual hires = fewer bad hires
Fewer bad hires × replacement cost = annual savings
Example Calculation:
• Before: 8% bad hire rate (industry average)
• After: 4% bad hire rate (50% improvement)
• 4% reduction × 60 hires = 2.4 fewer bad hires
• Replacement cost: $85K salary × 150% = $127,500 per bad hire
• 2.4 × $127,500 = $306,000 annual savings
Hiring Manager Time Savings
Managers spend less time on unqualified candidates and redundant interviews.
Calculation Formula:
Hours saved per hire × annual hires = total hours saved
Total hours × avg manager hourly rate = annual savings
Example Calculation:
• 5 hours saved per hire (fewer unqualified candidate interviews)
• 60 hires × 5 hours = 300 hours saved
• Average hiring manager cost: $125/hour
• 300 × $125 = $37,500 annual savings
Reduced Agency/Job Board Spend
Better internal sourcing and conversion reduces reliance on expensive external channels.
Calculation Formula:
Hires shifted from agency to internal × agency fee = savings
Example Calculation:
• Before: 25% of hires via agency (15 hires)
• After: 10% of hires via agency (6 hires)
• 9 fewer agency hires
• Average agency fee: 20% of first-year salary = $17,000
• 9 × $17,000 = $153,000 annual savings

Building Your Custom ROI Model
Every company's numbers are different. Here's how to build your own model:
Step 1: Gather Your Current Metrics
✓ Annual hires
Look at last 12 months of hiring
✓ Average time-to-fill
Days from req open to offer accepted
✓ Average salary by role
Weighted average of all hires
✓ Bad hire/turnover rate
% who leave or underperform in first year
✓ Recruiter fully-loaded cost
Salary + benefits + overhead
✓ Agency/job board spend
Annual external sourcing costs
Step 2: Benchmark Expected Improvements
Use these conservative benchmarks (actual results often exceed these):
Step 3: Calculate Your ROI
Plug your numbers into each benefit category formula. Use conservative assumptions (you can always exceed them).
