Carpet Cost Calculator
Calculate the total cost of a carpet installation project including carpet, padding, labor, and taxes.
Formula & Explanation
Total carpet installation cost is calculated as: 1. Calculate room area: Area = Length × Width (in square feet) 2. Apply waste factor: Carpet Yards = Area × (1 + Waste Factor) ÷ 9 3. Calculate material costs: - Carpet Cost = Carpet Yards × Price Per Sqyd - Padding Cost = Carpet Yards × Padding Cost Per Sqyd - Labor Cost = Carpet Yards × Labor Cost Per Sqyd 4. Calculate subtotal: Subtotal = Carpet Cost + Padding Cost + Labor Cost 5. Calculate tax: Tax = Subtotal × Tax Rate 6. Calculate total: Total = Subtotal + Tax All monetary amounts are in dollars. Note: 1 square yard = 9 square feet.
Assumptions
- •Room is rectangular with perpendicular walls
- •Measurements are in feet
- •Carpet is sold and priced per square yard
- •Padding is sold and priced per square yard
- •Labor is charged per square yard of carpet installed
- •Waste factor of 10% is typical for rooms narrower than 12 feet
- •Waste factor of 15% is recommended for rooms wider than 12 feet (seam penalty)
- •Padding densities: 6 lb (economy), 8 lb (standard), 10 lb (premium) - discuss with installer
- •Tax is calculated on combined material and labor costs
- •Additional costs (removal, disposal, furniture moving) are not included
- •Stairs, complex patterns, and custom seaming may increase labor costs
Example Calculation
A 12×12 ft room (144 sqft = 16 sqyd base) with 10% waste needs 17.6 sqyd. At $6/sqyd carpet, $1.50/sqyd padding, and $4/sqyd labor, with 8% tax, the total is $216.42.
