Enter the area to be covered and the cost per square foot into the calculator to determine the total cost of installing a vapor barrier.

Vapor Barrier Cost Formula

The following formula is used to calculate the total cost of a vapor barrier.

TC = A * C

Variables:

  • TC is the total cost ($)
  • A is the area to be covered (square feet)
  • C is the cost per square foot ($)

To calculate the total cost of a vapor barrier, multiply the area to be covered by the cost per square foot.

What is a Vapor Barrier?

A vapor barrier is a material used to prevent moisture from penetrating walls, ceilings, and floors into the interior spaces of a building. It is typically installed during construction or renovation to protect the building structure and indoor air quality from the damaging effects of moisture and mold. Vapor barriers are essential in areas with high humidity levels or in buildings where temperature differences can lead to condensation.

How to Calculate Vapor Barrier Cost?

The following steps outline how to calculate the total cost of installing a vapor barrier.


  1. First, determine the area to be covered (A) in square feet.
  2. Next, determine the cost per square foot (C) in dollars.
  3. Next, gather the formula from above = TC = A * C.
  4. Finally, calculate the total cost (TC) in dollars.
  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 to be covered (A) = 500 square feet

Cost per square foot (C) = $0.50
