Formula & Theory - HR Software ROI Calculator
The HR Software ROI Calculator uses this formulation:
Annual Cost = subscription + implementation + training + maintenance
Labour Saving = hours_saved_per_month × hourly_wage × 12
Annual Benefit = Labour Saving + recruiting + retention + compliance
Net Benefit = Annual Benefit - Annual Cost
ROI = Net Benefit / Annual Cost × 100%
Payback Period = Annual Cost / (Net Benefit / 12)| Symbol | Meaning |
|---|---|
| Subscription | Yearly SaaS licence fee |
| Implementation | One-time setup expenses amortized as year-1 cost |
| Hours Saved | Total HR hours freed per month |
| Hourly Wage | Average loaded hourly cost of HR staff |
Assumptions and Limits
The HR Software ROI Calculator assumes savings are realized linearly across the year. Real ROI may take 6-12 months to ramp up. Validate assumptions with the vendor’s case studies before approving the budget.
