Labor Cost Savings from Automation Calculator
Estimate how much your organization can save annually by automating manual labor tasks, and determine your return on investment and payback period.
Formulas Used
Total Annual Hours on Task
= Number of Employees × Hours per Week × Working Weeks per Year
Total Annual Labor Cost
= Total Annual Hours × Hourly Wage × Benefits & Overhead Multiplier
Annual Labor Cost Saved
= Total Annual Labor Cost × (Automation Percentage / 100)
Net Annual Savings
= Annual Labor Cost Saved − Annual Maintenance & Licensing Cost
First-Year Net Savings
= Net Annual Savings − One-Time Implementation Cost
ROI (%)
= ((Net Annual Savings − Implementation Cost) / Implementation Cost) × 100
Payback Period (months)
= Implementation Cost / (Net Annual Savings / 12)
Hours Freed per Year
= Total Annual Hours × (Automation Percentage / 100)
Assumptions & References
- The Benefits & Overhead Multiplier accounts for employer-paid benefits (health insurance, retirement, payroll taxes, etc.). A common rule of thumb is 1.25–1.40 (25–40% above base wages). Source: U.S. Bureau of Labor Statistics, Employer Costs for Employee Compensation.
- Automation rarely achieves 100% replacement; a realistic range is 60–85% for most repetitive tasks. Source: McKinsey Global Institute, "A Future That Works: Automation, Employment, and Productivity" (2017).
