Spray Foam Insulation Cost Calculator

Introduction: Spray foam insulation is an excellent choice for improving the energy efficiency of your home or building. Whether you’re considering insulating your attic, walls, or another area, it’s crucial to estimate the cost accurately. The Spray Foam Insulation Cost Calculator simplifies this process, allowing you to budget effectively for your insulation project.

Formula: To estimate the cost of spray foam insulation, this calculator considers:

  • Area to Insulate (in square feet): The total area you plan to insulate.
  • Cost per Square Foot ($): The cost per square foot of spray foam insulation.

The formula used to estimate the cost is:

Total Cost = Area to Insulate (sq ft) × Cost per Square Foot ($)

How to Use:

  1. Enter the Area to Insulate in square feet.
  2. Input the Cost per Square Foot for spray foam insulation in dollars.
  3. Click the “Calculate” button.
  4. The calculator will display the estimated cost of spray foam insulation for your project.

Example: For instance, if you want to insulate an area of 500 square feet, and the cost per square foot of spray foam insulation is $2.50:

Total Cost = 500 sq ft × $2.50/sq ft = $1,250
