How We Calculate Your ROI
🏗️ Tower System (Manual UVC) Calculations
Step 1: Calculate Daily Human Time Required
How much time do staff spend repositioning the tower each day?
Daily Minutes = rooms × cycles × min
Daily Minutes = minutes
Step 2: Calculate Annual Human Hours
Convert daily minutes to annual hours worked
Annual Hours = ( min ÷ 60) × workdays
Annual Hours = hours/year
Step 3: Calculate Annual Labor Cost
Multiply hours by hourly labor rate
Labor Cost = hours × $/hr
Labor Cost =
Step 4: Calculate Annual Equipment Cost (Depreciation)
Spread the equipment cost over 5 years
Annual Equipment = $ ÷ 5 years
Annual Equipment =
Step 5: Calculate Annual Maintenance Cost
Maintenance as a percentage of equipment cost
Maintenance = $ × %
Maintenance =
📌 Tower Total Annual Cost
Total = Labor + Equipment + Maintenance
Total = + +
Total =

📌 Robot Total Annual Cost
Total = Labor + Equipment + Maintenance
Total = + +

💰 Savings & ROI Calculations
Annual Savings Calculation
How much money do you save per year by switching to the robot?
Annual Savings = Tower Total - Robot Total
Annual Savings = -
Annual Savings =
Annual ROI (Return on Investment)
What percentage return do you get on your robot investment each year?
Annual ROI = (Annual Savings ÷ Robot Cost) × 100
Annual ROI = ( ÷ $) × 100
Annual ROI = %
Payback Period
How long until the robot pays for itself?
Payback Period = Robot Cost ÷ Annual Savings
Payback Period = $ ÷
Payback Period = years
💡 Key Insight: These calculations show the complete financial picture of switching from manual tower repositioning to autonomous robot operation, including all labor, equipment, and maintenance costs over time.
