Use our spray foam insulation cost calculator to get an instant estimate on your insulation project.

## How to Use the Spray Foam Insulation Cost Calculator

To use the calculator:

- Enter the total area to be insulated in square feet.
- Enter the desired depth of the foam in inches.
- Enter the cost of insulation per square foot.
- Click the “Calculate” button.

The calculator will then compute the total cost based on your inputs.

## How It Works

The calculator multiplies the area to be insulated by the foam depth to determine the total volume required for insulation. It then multiplies this volume by the cost per square foot to give you the total cost.

## Limitations

This calculator assumes a linear relationship between the depth of the foam and the cost, which may not always be accurate for various insulation projects. Additionally, it does not consider factors like labor costs, waste, or the potential need for additional materials, which could affect the final cost.
