1. What is the Home Addition Calculator?

The Home Addition Calculator By Square Footage Tool estimates the cost of home additions by multiplying the square footage by the tool rate. This provides a quick estimate for budgeting and planning purposes.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Sq\ Ft \) — Square footage of the addition
• \( Tool\ Rate \) — Cost per square foot for the addition
