ROI Calculation

Example: Machine Tending

MANUAL OPERATION:
• Labor cost: $25/hour
• Shift: 8 hours
• Days/year: 250
• Annual labor cost: $25 × 8 × 250 = $50,000

ROBOT IMPLEMENTATION:
• Robot cost: $60,000
• Integration: $30,000
• Tooling: $10,000
• Total investment: $100,000
• Annual maintenance: $5,000
• Labor for oversight: $15,000
• Annual operating cost: $20,000

Annual savings: $50,000 - $20,000 = $30,000
Payback: $100,000 / $30,000 = 3.3 years
5-year savings: $150,000 - $100,000 = $50,000

ROI Factors
