How Do You Calculate Demolition Costs


Calculating demolition costs is crucial for anyone involved in construction, renovation, or property development projects. Whether you’re a homeowner planning to demolish part of your property or a contractor taking on a larger project, understanding the costs involved is essential. In this article, we provide a straightforward demolition cost calculator and a guide on how to use it effectively.


The demolition cost is calculated by multiplying the total square footage by the cost per square foot. In simple terms:

Demolition Cost = Total Square Footage x Cost Per Square Foot

How to Use

Using the provided calculator is straightforward. Follow these steps:

  1. Enter the total square footage of the area to be demolished in the “Total Square Footage” field.
  2. Specify the cost per square foot for the demolition in the “Cost Per Square Foot” field.
  3. Click the “Calculate” button.

The calculator will provide you with the estimated demolition cost, helping you budget your project effectively.


Suppose you have a building with a total square footage of 2,000 square feet, and the demolition cost per square foot is $5. Using the calculator, you would enter:
