Enter the area of the floor and the coating thickness into the calculator to determine the amount of floor wax needed. This calculator can also evaluate any of the variables given the others are known.

Floor Wax Formula

The following formula is used to calculate the amount of floor wax needed.

FW = (A * C) / E

Variables:

  • FW is the amount of floor wax needed (oz)
  • A is the area of the floor (sq ft)
  • C is the coating thickness (oz/sq ft)
  • E is the efficiency of the wax application (%)

To calculate the amount of floor wax needed, multiply the area of the floor by the desired coating thickness. Then divide the result by the efficiency of the wax application.

What is a Floor Wax?

Floor wax is a type of material used to protect and add shine to floors. It is typically made from a mixture of solvents, waxes, resins, and oils that create a hard, protective finish when applied to surfaces like wood, vinyl, or linoleum. Floor wax not only enhances the appearance of the floor but also provides a layer of protection against scratches, stains, and water damage. It requires periodic stripping and reapplication to maintain its protective qualities and aesthetic appeal.

How to Calculate Floor Wax?

The following steps outline how to calculate the amount of floor wax needed.


  1. First, determine the area of the floor (A) in square feet.
  2. Next, determine the coating thickness (C) in ounces per square foot.
  3. Next, gather the formula from above = FW = (A * C) / E.
  4. Finally, calculate the amount of floor wax needed (FW) in ounces.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

area of the floor (A) = 500 sq ft

coating thickness (C) = 0.5 oz/sq ft

efficiency of the wax application (E) = 80%
