Example Calculation

Let’s say you’re replacing carpet in a 15 ft × 12 ft room:

• Carpet Price: $3.50 per sq ft
• Padding Price: $0.75 per sq ft
• Installation Cost: $1.50 per sq ft
• Waste Percentage: 10%
• Removal Cost: $80
• Furniture Moving Cost: $50

Step-by-Step Calculation:

1. Room Area: 15 × 12 = 180 sq ft
2. Area with Waste: 180 × 1.10 = 198 sq ft
3. Carpet Cost: 198 × $3.50 = $693.00
4. Padding Cost: 198 × $0.75 = $148.50
5. Installation Cost: 198 × $1.50 = $297.00
6. Add Removal: + $80
7. Add Furniture Moving: + $50

Total Estimated Cost = $1,268.50
