1. What is the House Addition Estimate?

The House Addition Estimate Calculator provides a quick calculation of potential costs for home additions based on square footage and local real estate rates. This helps homeowners and contractors budget for expansion projects.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• \( Sq\ Ft \) — Square footage of the planned addition
• \( RE\ Rate \) — Current real estate rate per square foot in your area

Explanation: The calculation multiplies the size of the addition by the current construction cost per square foot in your local market.

3. Importance of Accurate Estimation

Details: Proper estimation helps in budgeting, securing financing, and comparing contractor bids. Underestimating can lead to financial shortfalls while overestimating may make projects seem unaffordable.

4. Using the Calculator

Tips:

• Measure the exact square footage of your planned addition
• Research current construction costs per square foot in your area
• Consider adding 10-20% for unexpected costs
