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.

Number of Employees Performing the Task

Average Hourly Wage per Employee ($)

Hours Spent on Task per Employee per Week

Working Weeks per Year

Percentage of Task Automated (%)

Benefits & Overhead Multiplier (e.g. 1.25 = 25% on top of wages)

One-Time Automation Implementation Cost ($)

Annual Automation Maintenance / Licensing Cost ($)

// --- Core Formulas --- // Total annual labor hours spent on the task across all employees var totalAnnualHours = numEmployees * hoursPerWeek * weeksPerYear;

#### 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)
