How Much Does Carpet Installation Cost? (2026 Prices)

Updated October 2026

Carpet installation costs $1.36–$13.58 per square foot installed, averaging about $7.47 — and that total is carpet material + padding + labor, three separate per-square-foot numbers stacked. Fiber is the biggest lever: polyester material starts near $0.5/sq ft and wool reaches $21/sq ft; nylon sits in the durable middle at $0.75–$9. Padding runs $0.25–$2 and labor $0.5–$1.5 per square foot. A typical 12×12 room lands roughly $196–$1,956; a staircase adds $3–$40 per step; old-carpet removal is $1–$3/sq ft (often included).

Cost per square foot — the headline

The single number people quote is the installed total, and it has four publishers behind it (each kept per source, never averaged):

The wide band is real: the low end is a thin budget carpet over existing subfloor with included removal; the high end is a premium fiber with new padding, stairs and prep. Fixr's $7.47/sq ft is the dataset's typical figure.

Cost by fiber — the biggest driver

Fiber sets the material price (padding and labor are added on top). These are material-only, per square foot:

The three publishers frame their own low-to-high, so the bands differ — but the ordering is consistent: polyester/olefin → nylon/triexta → wool. Pick the fiber for the traffic and the budget, then the style narrows it further.

Cost by style

Construction and pile height move the price within a fiber (single publisher — HomeAdvisor — flagged):

Style and fiber multiply: a textured nylon and a berber wool are different constructions at different prices. Read the style band together with the fiber band.

Cost by room size

Scale the installed band to your space (CarpetExchange; typical room 12×12 = 144 sq ft):

The 12×12 row is simple arithmetic on the cited per-sq-ft band, shown for scale; the 1,000 / 2,000 sq-ft rows are CarpetExchange's own examples.

Material vs padding vs labor — what's in the number

The installed price is three purchases, and knowing them explains quote gaps:

1. Carpet material — $0.50–$21.00/sq ft (by fiber, then style). The dominant lever.
2. Padding — $0.25–$2/sq ft (typical $0.75): thickness/density (lb) and bonded-vs-rebond fiber. Fixr frames it as “$0.35–$1.14 added”; CarpetExchange $0.25–$1.00; HomeAdvisor $0.75–$2.00.
3. Labor — $0.5–$1.5/sq ft (typical $1): stretch/fit/seam work, room count and layout. Fixr frames it as “$0.74–$1.17”; CarpetExchange $0.50–$1.50.

A quote that looks cheap can be cheap in exactly one of these — budget fiber with thin pad and a thin labor line — while a “high” quote may include a premium fiber, upgraded pad, and moving furniture. Ask which lines are itemized.

Stairs — the add-on outside the per-square-foot price

Carpeting a staircase is quoted per step, not per square foot, because each tread is individually wrapped and takes more labor:

• Modernize (total): $15–$40 per step, or $300–$450 for a standard 13–15-step project (low $150, high $600+).
• Thumbtack (labor-only): $3–$10 per step.

The recorded band of $3–$40 spans both bases — kept per source, never averaged. When you get a stairs quote, ask whether the figure is a total (material + labor) or labor only.

Removal, disposal and prep

• Old-carpet removal & disposal: $1–$3 per square foot (HomeAdvisor — single publisher, flagged; Modernize publishes a per-step variant of $1–$3). Many installers include removal in the install quote — confirm, because it can vanish from the bill.
• Subfloor prep and any transition strips/adhesive are additional line items quoted per job — verify at source with your installer.

DIY vs hiring an installer

Carpet is one of the least DIY-friendly floor jobs — it needs a power stretcher, seaming tools and a knee-kicker to be done without ripples and open seams, and a bad stretch shows within months. The honest split:

• Pro territory: almost always — stretch-in carpet over pad, stairs, seaming across rooms, and anything needing a power stretcher.
• DIY-able: pulling up old carpet and pad (but disposal is still $1–$3/sq ft if you don't haul it), and minor furniture moving.

Confirm the furniture-moving policy: many installers include basic moving, but heavy items and overnight staging may add cost.
