How much does carpet cost?

Installed carpet typically runs about $2–$8 per square foot all-in — that's the carpet itself ($1–$5/sq ft), plus padding and labor. For a 12 × 15 ft room (180 sq ft), expect roughly $400–$1,400 installed, depending on the carpet grade and your area.

Cost breakdown

The cost of carpet per square foot is about $1–$5 for the carpet alone, or roughly $2–$8 installed once you add padding and labor. Carpet is often quoted per square yard (1 sq yd = 9 sq ft); here it's broken down per square foot for clarity (US estimates):

ItemTypical cost
Builder-grade carpet$1–$2 / sq ft
Mid-range carpet$2–$4 / sq ft
High-end / wool$5+ / sq ft
Padding$0.30–$0.60 / sq ft
Installation$0.50–$1.50 / sq ft

Cost by room

Using the $2–$8 / sq ft installed range, here's what common spaces tend to run:

SpaceApprox. areaInstalled cost
Bedroom~120 sq ft$250–$1,000
Living room~300 sq ft$600–$2,400
Staircase~13 steps$200–$500
Whole house1,500–2,500 sq ft$3,000–$20,000

Scaling up, 800 sq ft of carpet costs roughly $1,600–$6,400 installed — handy for a large basement or several rooms done at once. The carpet grade you choose is still the biggest swing in the total.

Carpet is cut from 12-ft rolls You buy the cut: 12 × 13 ft = 156 sq ft Room: 10 × 13 ft = 130 sq ft Waste 12-ft roll The roll is 12 ft wide — a 10-ft-wide room still takes a 12-ft cut
Broadloom comes on 12-ft rolls: you pay for the cut, not the room’s area, and rooms wider than 12 ft add a seam.

Cost by carpet type

Fiber is the biggest lever on price and durability (carpet only, before padding and labor):

FiberCarpet / sq ftBest for
Olefin (polypropylene)$1–$3Budget, basements, low traffic
Polyester (PET)$1–$3Soft, stain-resistant, bedrooms
Nylon$2–$5Durable, high-traffic areas
Wool$5–$12+Premium, natural, long-lasting

What changes the price

  • Carpet type. Fiber (nylon, polyester, wool) and pile style drive most of the price range.
  • Padding. Don't skip it — good padding extends carpet life and is sold separately.
  • Room shape & stairs. Seams, closets, and stairs add labor and waste.
  • Old floor removal. Tear-out and haul-away of old carpet may be extra.

Ways to save

  • Move your own furniture before the installers arrive.
  • Buy carpet and pad together and ask for an all-in installed price.
  • Order the right amount — about 10% waste avoids a second order without overspending. Measure first with our room measuring guide.

Frequently asked questions

How much to carpet a 12×12 room?
144 sq ft at $2–$8 / sq ft installed is about $300–$1,150, including carpet, padding, and labor.
How much to carpet stairs?
Roughly $15–$40 per stair installed — about $200–$500 for a typical 13-step staircase — since each step is labor-intensive.
What's the cheapest carpet?
Olefin and basic polyester at about $1–$3 / sq ft. Fine for low-traffic rooms, but they don't wear like nylon.
How much is carpet padding?
About $0.30–$0.60 / sq ft. Don't skip it — it extends carpet life and is usually required for the warranty.
Is it cheaper to install carpet yourself?
DIY saves the $0.50–$1.50 / sq ft labor, but carpet needs a power stretcher and knee kicker to avoid wrinkles — and retailers often bundle low-cost install, so hiring out is frequently the better deal.
How long does carpet last?
About 5–15 years — longer for quality nylon in low-traffic rooms, shorter for budget carpet in busy areas.
