Estimated Cost Range: Low and high ends based on your chosen carpet type's per-square-foot price range, applied to the waste-adjusted area.
Total Sq Ft Needed: The raw room area plus your waste percentage — this is how much carpet to buy.
Square Yards: The same room area expressed in square yards, since many retailers price carpet per square yard.
Padding Needed: Equal to your raw room area (before waste), since carpet padding is typically sold to cover the room footprint.
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.
