How to Use This Calculator

Enter the total carpet area in square feet to be cleaned.
Set the production rate (sq ft/hr) for your equipment -- portable units average 800-1,200, truck-mounts 1,500-2,500.
Enter the chemical concentrate cost per gallon and the dilution ratio.
Set the labor rate and soil level (1 = light, 3 = heavy) to adjust cleaning time.
Review the total job cost, cost per sq ft, and labor hours to build your customer quote.

How the result changes with Soil level (1-3)

Soil level (1-3)	Cleaning time (hrs)	Total job cost
1.2	3.03	$91.90
1.7	3.03	$92.04
2.3	3.03	$92.21
2.8	3.03	$92.35

What each input means

Carpet area (sq ft): Total square footage of carpet to be cleaned.
Production rate (sq ft/hr): Equipment cleaning rate. Portable: 800-1,200; truck-mount: 1,500-2,500 sq ft/hr.
Chemical cost ($/gal concentrate): Cost per gallon of cleaning concentrate.
Dilution ratio (1:X): Concentrate dilution ratio. Typical HWE pre-spray: 1:128.
Labor rate ($/hr): Hourly wage for the cleaning technician.
Soil level (1-3): 1 = light soil, 2 = medium, 3 = heavy. Affects speed and chemical usage.

What each result means

Cleaning time (hrs): Estimated hours to complete extraction.
Solution needed (gal): Total gallons of diluted cleaning solution.
Chemical cost: Cost of cleaning chemicals for the job.
Labor cost: Total labor cost based on cleaning hours.
Equipment wear cost: Estimated equipment depreciation/maintenance cost.
Total job cost: Combined labor, chemical, and equipment cost.
Cost per sq ft: Total cost divided by area cleaned.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Carpet area (sq ft) = 2000, Production rate (sq ft/hr) = 1200, Chemical cost ($/gal concentrate) = 12, Dilution ratio (1:X) = 128 = 6 input(s) provided
Calculate Cleaning time
Cleaning time = sqFt / max(1, effectiveRate)
1.67 = 1.67
Calculate Total job cost
Total job cost = laborCost + chemicalCost + equipmentCost
50.94 = $50.94
Calculate Solution needed
Solution needed = (sqFt / 100) * galPer100
10 = 10
Calculate Chemical cost
Chemical cost = concentrateGal * chemCostPerGal
0.94 = $0.94
