Carpet Installation Cost Per Sq Ft Calculator
Enter your room area and instantly see the total cost of carpet, padding, and installation.
Carpet showrooms quote an installed price — bundling carpet, pad, and labor into one figure — which makes it hard to know if you're getting a fair deal. This calculator breaks it down by square foot so you can see exactly what $3 vs $7 per sq ft gets you in quality and durability.

How much does carpet installation cost per square foot?
Basic polyester or nylon carpet installation costs $2–$5 per sq ft all-in (carpet + pad + labor). Mid-range carpet runs $4–$7 per sq ft installed. Premium wool or cut-pile options can reach $8–$15 per sq ft. Removing old carpet typically adds $0.50–$1 per sq ft. Stairs are quoted separately — usually $3–$10 per step. Always measure and order 10% extra to cover cuts and doorway thresholds. Comparing carpet to hard flooring? Our flooring cost per sq ft calculator covers LVP, laminate, hardwood, and tile so you can see the full picture.

What affects flooring cost per square foot?
Carpet fibre type
Polyester is the most affordable at $1–$3/sq ft for material. Nylon is more durable at $2–$5/sq ft. Wool is the premium option at $5–$15/sq ft. Triexta (SmartStrand) is a popular mid-range choice with excellent stain resistance.
Carpet pile type
Cut pile (plush, saxony) is soft and popular for bedrooms. Loop pile (Berber) is more durable for high-traffic areas. Cut-loop (pattern) carpets cost more to install due to directional matching requirements.
Padding quality
Standard 6 lb density rebond pad is cheapest at $0.25–$0.50/sq ft. Higher density pads ($0.50–$1.50/sq ft) extend carpet life significantly and add noticeable comfort underfoot — worth the upgrade.
Old carpet removal
Removing and disposing of existing carpet and padding adds $0.50–$1/sq ft. Most professional installers offer this as an add-on. DIY removal can save money and is relatively easy for most homeowners.
Stairs
Stairs are quoted per step, not per square foot — typically $3–$10 per step. Waterfall installation (folded over the edge) is cheaper than Hollywood style (wrapped around each individual step).
Room layout & seams
Standard carpet rolls are 12 ft wide. Rooms wider than 12 ft require seams. Good installers position seams in low-traffic areas where they'll be less visible. More seams means more labour and material waste.
Frequently asked questions
How much does it cost to carpet a 12×12 room?
Carpeting a 12×12 ft room (144 sq ft) costs $290–$1,010 all-in including carpet, pad, and installation at $2–$7/sq ft. Mid-range carpet and quality pad brings the typical cost to $400–$700 for this size room.
What is the cheapest carpet you can buy per square foot?
Basic polyester carpet can be found for $0.99–$2/sq ft for material only. With standard pad and installation, the all-in cost is $2–$4/sq ft. Builder-grade carpet used in rentals and new construction is in this range — functional but not particularly durable under heavy traffic.
How long does carpet installation take?
A professional crew can install carpet in 1–3 rooms per day. A whole house (1,000–1,500 sq ft) typically takes 1–2 days. Furniture moving, old carpet removal, and stair installation all add time to the project.
How long does carpet last?
Budget polyester carpet lasts 5–8 years in medium traffic. Mid-range nylon carpet lasts 10–15 years. Premium nylon or wool carpet can last 15–25 years with proper care. Regular vacuuming and professional cleaning every 1–2 years significantly extends lifespan.
Is it worth replacing carpet with hard flooring?
Hard flooring (LVP, hardwood, tile) lasts longer, is easier to clean, and is better for allergy sufferers. Carpet is warmer, softer underfoot, and better suited for bedrooms and playrooms. LVP costs $3–$8/sq ft vs $2–$7/sq ft for carpet — similar upfront, but hard flooring lasts significantly longer and typically adds more resale value.
