How to Use This Calculator

Enter the total cleanable area in square feet and the number of patient or exam rooms.
Set the average high-touch points per room (CDC recommends tracking 30-50).
Enter the EPA-required disinfectant contact time in minutes.
Input disinfectant cost per RTU gallon and EVS labor rate per hour.
Review total cleaning hours, staff needed per shift, and total cost per room for staffing decisions.

Identify Input Parameters
4 parameters
Total area (sq ft) = 3000, Number of rooms = 20, High-touch points per room = 35, Disinfectant contact time (min) = 3 = 6 input(s) provided
Calculate Total cleaning hours
Total cleaning hours = floorCleanHours + highTouchHours + dwellOverheadHours
33.94 = 33.94
Calculate Staff needed
Staff needed = ceil(totalCleaningHours / 8)
5 = 5
Calculate Total cleaning cost
Total cleaning cost = laborCost + disinfectantCost + ppeCost
830.43 = $830.43
Calculate Disinfectant needed
Disinfectant needed = floorDisinfectantGal + highTouchDisinfectantGal
7.3 = 7.3
Calculate Disinfectant cost
Disinfectant cost = totalDisinfectantGal * disinfectantCostPerGal
159.5 = $159.5
