What Your Result Means

How This Calculator Works

You enter the room's length and width in feet, choose a carpet type, and set a waste percentage (10% is standard). The tool multiplies length by width for raw area, adds the waste factor, and looks up the per-square-foot cost range for your carpet type. It also converts area to square yards and shows padding at the raw room area.

Quick Questions

How much waste should I plan for?

10% is the industry standard for rectangular rooms. Add 15% for rooms with alcoves or angles, or pattern-match carpet.

Does this include installation cost?

No. The cost shown is for materials only. Professional carpet installation typically adds $1–$2 per square foot.

What's the difference between plush and berber?

Plush has a soft, even pile that shows footprints easily. Berber uses looped fibers for a flatter, more durable surface suited to high-traffic areas.

Do I need carpet padding?

Yes. Nearly all carpet installations require a separate pad underneath for comfort, insulation, and to extend carpet life.
