1. What is the Home Addition Estimate Calculator?

The Home Addition Estimate Calculator provides a preliminary cost estimate for home addition projects based on size, cost per square foot, and quality level factors.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Size \) — Addition size in square feet
• \( Cost\ Per\ Sq\ Ft \) — Base construction cost per square foot
• \( Quality\ Factor \) — 1.0 (Basic), 1.25 (Standard), or 1.5 (Premium)

Explanation: The calculation accounts for both the physical size of the addition and the quality level of materials and finishes.

3. Importance of Accurate Estimates

Details: Preliminary estimates help homeowners budget appropriately and understand the financial feasibility of their home addition projects before committing to detailed plans.

4. Using the Calculator

Tips: Enter the planned addition size in square feet, your local average cost per square foot for construction, and select the quality level that matches your project goals.
