Cost to Install Carpet on Stairs
Updated July 2026 · Pricing data from Floormath's flooring cost model
Stairs don't price like floors. Each step needs individual cuts, nosing, and finish work, so installers charge per step — Floormath models $135/step at national-average labor, adjusted by state. A typical 13-step flight runs about $1,755 before materials.
What a full staircase costs with carpet

| 10 steps | $1,350 | $1,823–$2,160 |
| 13 steps | $1,755 | $2,369–$2,808 |
| 16 steps | $2,160 | $2,916–$3,456 |
| 20 steps | $2,700 | $3,645–$4,320 |
| 26 steps | $3,510 | $4,738–$5,616 |
Stairs are priced per step, not per square foot — the labor is in the cuts and nosing work. Landings are measured as regular square footage and added on top.

Why are stairs so expensive to floor?
Every step requires individual measuring, cutting, and nosing installation — there's no economy of scale. At roughly $135 per step, a 13-step flight costs about $1,755 in labor alone.
Can I DIY carpet on stairs?
Stairs are the least DIY-friendly part of any flooring job. Bad nosing work is a safety hazard and the most visible flaw in the house. Most homeowners who DIY the floors still hire out the stairs.
