Training ROI Calculator
Estimate the financial return on investment for employee training programs using the Phillips ROI Methodology.
Number of Employees Trained
Average Annual Salary per Employee ($)
Estimated Productivity Gain (%)
Turnover Reduction (%)
Current Annual Turnover Rate (%)
Cost to Replace One Employee ($)
Total Training Program Cost ($)
Time Horizon (months)
Calculate ROI

#### Formulas Used
Productivity Benefit = (Employees × Avg Salary) × (Productivity Gain % / 100) × (Months / 12)
Retention Benefit = Employees × (Turnover Rate % / 100) × (Months / 12) × (Turnover Reduction % / 100) × Cost per Hire
Total Benefits = Productivity Benefit + Retention Benefit
Net Benefit = Total Benefits − Training Cost
ROI (%) = (Net Benefit / Training Cost) × 100
Benefit-Cost Ratio (BCR) = Total Benefits / Training Cost
Payback Period = Training Cost / (Total Benefits / Months)
#### Assumptions & References
- Based on the Phillips ROI Methodology (Jack J. Phillips, 1996), the industry standard for measuring training ROI.
- Replacement cost typically ranges from 50%–200% of annual salary depending on role complexity (SHRM, 2022).
- A BCR > 1.0 indicates the program generates more value than it costs; industry benchmark ROI is typically 25%–45% for well-designed programs (ATD, 2023).
