A flooring and carpet calculator estimates the floor area, recommended material quantity, and project cost using room dimensions, identical room count, waste allowance, material price, and installation rate.
📏 Base Area: Length × Width × Number of Identical Rooms
✂️ Waste Allowance: Base Area × Waste Percentage ÷ 100
➕ Area With Waste: Base Area + Waste Allowance
📐 Square Yards: Area With Waste ÷ 9
📦 Material Cost: Area With Waste × Material Price per sq ft
🛠️ Installation Cost: Base Area × Installation Cost per sq ft
💰 Total Cost: Material Cost + Installation Cost
For two 12 ft × 15 ft rooms, the base area is 360 sq ft. With a 10% waste allowance, the recommended material quantity is 396 sq ft, equal to 44 sq yd.
This estimate assumes rectangular rooms with identical dimensions when more than one room is selected. Material cost includes the selected waste allowance, while installation cost is calculated from the base floor area.
Taxes, delivery, underlay or padding, old-floor removal, disposal, subfloor preparation, stairs, baseboards, trims, and transitions are not included.

Enter the room length and width in feet. The calculator multiplies one room’s area by the number of identical rooms.
Many carpet and flooring projects use 5–10% waste. Complex shapes, closets, hallways, seams, and patterned materials may require 10–20% or more.
Enter the material price per square foot. If carpet is quoted by the square yard, divide the square-yard price by 9 before entering it.
Material cost uses the area with waste. Installation cost uses the actual base floor area and excludes extra material waste.
Multiply room length by room width and by the number of identical rooms, then add an appropriate waste allowance.
Yes. In United States mode, material, installation, and total costs are labeled in USD.
No. Installation is calculated from the base floor area. Material cost is calculated from the area including waste.
Yes. The area and cost formulas can be used for carpet, vinyl, laminate, and other flooring materials priced by the square foot.
