Step 6: Click Calculate
After entering all information, the calculator provides:
- Base demolition cost
- Labor-adjusted cost
- Waste disposal cost
- Equipment cost
- Total demolition cost
- Cost per square foot
Demolition Cost Calculation Formula
The calculator uses several formulas to estimate the total demolition cost.
1. Base Demolition Cost Formula
The basic calculation is:
Base Cost = Building Area × Demolition Rate
Where:
- Building Area = Total square feet
- Demolition Rate = Cost per square foot based on demolition type
Example:
A 2,000 sq ft residential demolition:
2,000 × $8
= $16,000 base demolition cost
2. Labor Adjusted Cost Formula
Labor adjustments are calculated as:
Labor Cost = Base Cost × Labor Factor
Examples:
Standard labor:
$16,000 × 1
= $16,000
High labor cost area:
$16,000 × 1.25
= $20,000
3. Waste Disposal Cost Formula
Waste expenses are calculated using:
Waste Cost = Labor Cost × (Waste Factor - 1)
Example:
If labor-adjusted cost is $20,000 and waste factor is 1.15:
$20,000 × (1.15 - 1)
= $3,000 waste cost
4. Total Demolition Cost Formula
The final cost is:
Total Cost = Labor Cost + Waste Cost + Equipment Cost
This provides the complete estimated demolition expense.
5. Cost Per Square Foot Formula
The average cost per square foot is:
Cost Per Sq Ft = Total Cost ÷ Building Area
This helps compare project costs with industry averages.
Demolition Cost Example Calculation
Let’s calculate the demolition cost for a residential building.
Project Details:
- Building area: 2,500 sq ft
- Demolition type: Residential
- Demolition rate: $8 per sq ft
- Labor adjustment: Standard
- Waste disposal: Moderate (+15%)
- Equipment cost: $3,000
Step 1: Calculate Base Cost
Formula:
Area × Rate
2,500 × $8
= $20,000
Step 2: Calculate Labor Cost
Standard labor factor:
$20,000 × 1
= $20,000
Step 3: Calculate Waste Cost
Moderate waste factor:
$20,000 × (1.15 - 1)
= $3,000
Step 4: Add Equipment Cost
$20,000 + $3,000 + $3,000
= $26,000
Step 5: Calculate Cost Per Square Foot
$26,000 ÷ 2,500
= $10.40 per sq ft
The estimated demolition cost would be:
- Base Cost: $20,000
- Waste Cost: $3,000
- Equipment Cost: $3,000
- Total Cost: $26,000
- Cost Per Square Foot: $10.40
