What moves the number in a 20x24 room

The spread comes almost entirely from product tier: Polyester Cut-Pile Carpet and Wool Carpet — Luxury are several dollars per square foot apart, which compounds to a four-figure gap in a 480 sq ft room. Labor is steadier — about $840 here at national rates, drifting 15–25% with your state. Every figure already carries the industry-standard 10% material waste allowance.

Carpet note: figures include a standard rebond pad ($0.60/sf). Upgrading to memory-foam pad adds roughly $240–$480 but extends carpet life.
Example mid-range build: Nylon Cut-Pile Carpet (Nylon fiber · Cut pile · 35–45 oz face weight) — material $2,107, labor $1,128, total $3,235 for the full 20x24 room.
