Carpet pricing can feel confusing. Some stores quote per square foot, others per square yard. Fiber type, density, brand, and padding all move the number. Then installation labor, furniture moving, old carpet removal, and stair charges pile on top. Without a clear understanding of how carpet is priced, it is easy to overpay or underestimate your budget.
This guide breaks down every factor that affects carpet pricing so you can walk into any store or request any quote with confidence.
Per Square Foot vs. Per Square Yard
The carpet industry has historically priced products per square yard (sq yd). One square yard equals nine square feet. Many big-box stores have shifted to per-square-foot pricing to make numbers seem lower and to simplify comparisons. Both measurements describe the same thing, so always convert to the same unit before comparing quotes.
Quick conversion: Multiply the per-square-foot price by 9 to get the per-square-yard price, or divide the per-square-yard price by 9 to get the per-square-foot price.
For example, carpet listed at $4 per square foot equals $36 per square yard. If a competing store quotes $30 per square yard, that is $3.33 per square foot. The second option is cheaper, even though the dollar figure looked higher at first glance.
How Fiber Type Impacts Price
The fiber (also called the face fiber) is the yarn that makes up the carpet’s surface. It is the biggest single factor in the price of the carpet itself.
Nylon
Nylon is the most popular carpet fiber and the best performer overall. It resists wear, crushing, and staining (especially when treated with stain protection). Nylon carpet ranges from $2 to $8 per square foot for materials alone. Premium nylon brands like Stainmaster and Anso command the higher end of that range.
Polyester (PET)
Polyester is soft, stain-resistant, and available in vivid colors. It costs less than nylon, typically $1 to $4 per square foot. The trade-off is that polyester mats and crushes more easily in high-traffic areas. It works well in bedrooms and low-traffic living rooms.
Triexta (SmartStrand)
Triexta, branded by Mohawk as SmartStrand, is a newer polyester variant with significantly better crush resistance. It combines polyester softness with near-nylon durability. Pricing falls in the $2 to $6 per square foot range. It has become a strong mid-range choice for families and pet owners.
Olefin (Polypropylene)
Olefin is the budget fiber. It resists moisture and mildew, making it suitable for basements and outdoor applications. However, it crushes easily, stains from oil-based substances, and does not hold up to heavy traffic. Prices start around $1 per square foot.
Wool
Wool is the premium natural fiber. It offers unmatched softness, natural stain resistance, fire resistance, and a luxurious hand feel. Wool carpet starts around $5 per square foot and can exceed $20 for designer patterns. Expect higher maintenance costs as wool requires professional cleaning.
How Density and Face Weight Affect Price
Beyond fiber type, the amount of fiber packed into the carpet determines its quality and price.
Face Weight
Face weight measures how many ounces of fiber are in one square yard of carpet. A higher face weight generally means a denser, more durable carpet. Residential carpets typically range from 20 to 60 ounces.
- 20–30 oz: Entry-level. Fine for guest rooms and closets.
- 30–45 oz: Mid-range. Suitable for most bedrooms and family rooms.
- 45–60+ oz: Premium. Dense, plush, and built for heavy use and luxury feel.
Density
Density measures how tightly the fibers are packed together, regardless of pile height. A carpet can have high face weight but low density if the pile is very tall and loose. Density is calculated using face weight and pile height. Higher density means the carpet resists matting and crushing better and lasts longer.
For the best value, look for a carpet with density above 2,000. Premium products exceed 3,000.
Brand Tiers and What They Cost
Carpet brands fall into rough pricing tiers. Here is what to expect for materials only:
- Builder-grade / value ($1–$2/sq ft): Basic olefin or polyester. Thin, low density. Used in apartment complexes and spec homes. Brands: Dream Weaver, Home Decorators Collection.
- Mid-range ($2–$4/sq ft): Decent nylon or triexta. Moderate density and face weight. Solid performance for most homes. Brands: Shaw Floors, Mohawk, Stainmaster (select lines).
- Premium ($4–$8/sq ft): High-density nylon or triexta. Branded stain and wear warranties. Brands: Karastan, Stainmaster PetProtect, Mohawk SmartStrand Silk.
- Luxury ($8–$20+/sq ft): Wool, wool blends, designer patterns, custom textures. Brands: Karastan Kashmere, Couristan, Masland, custom-woven imports.
Carpet Padding Costs
Padding (also called cushion or underlay) sits between the carpet and the subfloor. It affects comfort, sound insulation, and carpet lifespan. Never skip padding, and never reuse old padding under new carpet.
- Basic rebond pad (6 lb density, 3/8″ thick): $0.30 to $0.60 per square foot.
- Standard rebond pad (8 lb density, 7/16″ thick): $0.50 to $0.80 per square foot. This is the sweet spot for most homes.
- Premium pad (memory foam, rubber, or fiber): $0.80 to $1.50 per square foot. Adds luxury feel and extended carpet life.
Most carpet manufacturers specify a minimum padding density and thickness to maintain the warranty. Going too thick or too soft can actually damage the carpet by allowing excessive flex.
Installation Labor Costs
Professional carpet installation typically costs $1 to $3 per square foot, depending on your location, the complexity of the job, and the installer’s experience.
- Simple room (rectangle, one doorway): $1 to $1.50 per square foot.
- Average home (multiple rooms, closets, hallways): $1.50 to $2 per square foot.
- Complex layout (stairs, angles, pattern matching): $2 to $3+ per square foot.
Many big-box stores offer free or discounted installation with a minimum carpet purchase. Read the fine print: “free installation” sometimes excludes padding, tack strips, transitions, and removal of old flooring.
Hidden Costs to Budget For
The carpet and installation quotes often do not include several additional expenses. Budget for these before you commit.
Stairs
Stairs are priced per step, not per square foot. Expect to pay $10 to $30 per step for installation, depending on the style (waterfall vs. cap-and-band) and the stair configuration (straight vs. curved). A typical 13-step staircase adds $130 to $390 to the installation bill.
Old Carpet Removal and Disposal
Some installers include removal in the quote. Others charge $0.50 to $1.50 per square foot or a flat fee of $100 to $300. Ask up front. If you want to save money, rip out the old carpet yourself. It requires only a utility knife, pliers, and some sweat.
Furniture Moving
Most installers expect rooms to be empty. If you need them to move furniture, expect a charge of $25 to $75 per room or a flat fee for the whole house. Move lightweight items yourself and leave only heavy pieces for the pros.
Subfloor Repair
If the subfloor has squeaks, damage, or moisture issues, it needs to be repaired before carpet goes down. Subfloor repair costs vary widely but can add $1 to $3 per square foot in affected areas.
Tack Strips and Transitions
Tack strips around the perimeter and transition strips at doorways are usually included in installation quotes, but confirm this. Replacement tack strips cost $0.10 to $0.30 per linear foot. Metal transitions cost $5 to $15 each.
Pattern Matching
Patterned carpet requires careful alignment at seams, which increases waste and labor time. Expect 10 to 20 percent more material than you would need with a solid-color carpet.
Total Cost Examples
Here is what a 1,000-square-foot carpet project might cost at three different quality levels:
Budget Project
- Carpet: $1.50/sq ft x 1,000 = $1,500
- Padding: $0.40/sq ft x 1,000 = $400
- Installation: $1.25/sq ft x 1,000 = $1,250
- Removal: $0.75/sq ft x 1,000 = $750
- Total: approximately $3,900
Mid-Range Project
- Carpet: $3.50/sq ft x 1,000 = $3,500
- Padding: $0.65/sq ft x 1,000 = $650
- Installation: $1.75/sq ft x 1,000 = $1,750
- Removal: $0.75/sq ft x 1,000 = $750
- Total: approximately $6,650
Premium Project
- Carpet: $6.00/sq ft x 1,000 = $6,000
- Padding: $1.00/sq ft x 1,000 = $1,000
- Installation: $2.25/sq ft x 1,000 = $2,250
- Removal: $0.75/sq ft x 1,000 = $750
- Total: approximately $10,000
Tips for Getting the Best Carpet Quote
- Get at least three quotes. Prices vary significantly between retailers and installers.
- Ask for itemized quotes. A single lump-sum number hides how much you are paying for each component.
- Compare apples to apples. Make sure each quote includes the same padding, installation services, and extras.
- Shop during sales. Holiday weekends (Memorial Day, Labor Day, Black Friday) and end-of-year clearances offer the deepest discounts.
- Negotiate padding and installation. Stores have more margin on these items than on the carpet itself.
- Bring your room measurements. An accurate square footage lets you compare quotes without relying on each store’s measuring visit.
Understanding how carpet is priced puts you in control. When you know what drives the cost, you can make smart trade-offs between fiber quality, density, padding, and installation to land on a floor you love at a price that works.
