- Driveway: 600 sq ft
- Garage floor: 500 sq ft
The larger the area, the higher the demolition cost will usually be.
Step 2: Enter Concrete Thickness
Input the thickness of the concrete slab in inches.
Common concrete thickness examples:
| Project Type | Typical Thickness |
|---|---|
| Sidewalk | 4 inches |
| Patio | 4 inches |
| Driveway | 4–6 inches |
| Garage floor | 4–6 inches |
| Foundation slab | 6+ inches |
Thicker concrete requires more effort, equipment, and disposal capacity.
Step 3: Enter Demolition Cost Per Square Foot
Enter the estimated demolition price charged per square foot.
Typical demolition rates may depend on:
- Concrete thickness
- Location accessibility
- Labor availability
- Equipment requirements
- Reinforcement inside concrete
For example, if demolition costs $3 per square foot and the area is 500 square feet:
500 × $3 = $1,500 demolition cost
Step 4: Add Debris Removal Cost
Concrete disposal is often a separate expense. Enter the estimated cost for:
- Loading debris
- Transportation
- Dumpster rental
- Recycling or landfill fees
Removing concrete can sometimes cost as much as demolition itself because concrete is heavy and difficult to transport.
Step 5: Add Additional Labor Costs

- Removal cost
- Labor cost
- Total estimated cost
- Cost per square foot
These results give you a complete overview of your expected demolition expenses.
Concrete Demolition Cost Calculation Formula
The calculator uses several formulas to estimate project costs.
1. Concrete Volume Formula
Concrete volume is calculated to determine how much material needs to be removed.
Formula:
Volume (Cubic Yards) = (Area × Thickness in Feet) ÷ 27
Since:
- 12 inches = 1 foot
- 27 cubic feet = 1 cubic yard
First, thickness is converted from inches into feet.
Example:
Concrete area = 500 sq ft
Thickness = 4 inches
Convert thickness:
4 ÷ 12 = 0.333 feet
Calculate volume:
(500 × 0.333) ÷ 27
= 6.17 cubic yards
The project contains approximately 6.17 cubic yards of concrete.
2. Demolition Cost Formula
The basic demolition cost depends on the area and price per square foot.
Formula:
Demolition Cost = Concrete Area × Demolition Rate
Example:
Area = 500 sq ft
Rate = $3 per sq ft
500 × 3 = $1,500
Estimated demolition cost:
$1,500
3. Total Project Cost Formula
The total cost includes demolition, debris removal, and additional labor.
Formula:
Total Cost = Demolition Cost + Removal Cost + Labor Cost
Example:
Demolition cost = $1,500
Removal cost = $500
Labor cost = $200
Total:
$1,500 + $500 + $200 = $2,200
4. Average Cost Per Square Foot Formula
The calculator also determines the final project cost per square foot.
Formula:
Cost Per Square Foot = Total Cost ÷ Concrete Area
Example:
Total cost = $2,200
Area = 500 sq ft
$2,200 ÷ 500
= $4.40 per sq ft
Practical Example of Concrete Demolition Cost Calculation
Suppose you want to remove an old concrete driveway.
Project details:
- Concrete area: 800 sq ft
- Thickness: 5 inches
- Demolition rate: $3.50 per sq ft
- Debris removal: $700
- Additional labor: $300
Step 1: Calculate Demolition Cost
800 × $3.50
= $2,800
Step 2: Add Removal and Labor
$2,800 + $700 + $300
= $3,800
Step 3: Calculate Cost Per Square Foot
$3,800 ÷ 800
= $4.75 per sq ft
Estimated project cost:
$3,800
Average demolition cost:
$4.75 per square foot
