Cleaning Chemical Calculator

Pad Life and Coverage Calculator

How many floor pads a job consumes at a stated pad life, and what the pads add to the chemical cost per square foot.

Inputs

Range: 1–1,000,000

Length times width of the area to be cleaned.

Range: 100–500,000 sq ft per pad

Area one pad cleans before it is spent. Aggressive stripping and gritty soil shorten it; a clean floor and light scrubbing extend it.

Range: 0–1,000,000 each

Enter the current purchase price in US dollars for the unit shown.

Result

Pad cost per 1,000 sq ft
$0.65
Pad cost for the area
$13.00
Pads needed
2 pads
Reading: what this result means for the job
A handful of pads. The pad cost is now a line in the bid rather than a rounding error, so record the area the last pad actually cleaned against this figure.
Applicability limit
The pad count follows the pad life entered, and pad life is a measured figure for one machine, one floor and one pass. Stripping, gritty soil and a heavy wet pick-up all shorten it, while a clean floor and light scrubbing extend it. This is a planning figure for the values entered, not a measured result. Coverage rates, product yields and application rates are properties of a specific product, applicator and substrate, and the label or data sheet for the product you are using always takes precedence over the default here. Cost covers the chemical only, at the price entered. It excludes labour, equipment, applicators, consumables, freight, storage, waste disposal and any over-pour that the allowance does not capture.

What to check

  • Record the area one pad cleaned before replacing it, rather than assuming a life.
  • Check the pad price for the grit and size actually used on the job.
  • Confirm whether the pad is being used for scrubbing or stripping, since the life differs.

Pad life is the one consumable figure that is almost never measured, and it moves the cost per square foot more than the chemical price does. Enter the area a pad actually cleaned before it was spent, not the number on the box.
