Reading the table for a 12x18 space
Notice how the installed range widens as tiers climb: material choice, not labor, is what separates a $620 job from a $5,189 one on the same 216 sq ft floor plan. Labor for mid-range carpet lands near $378 nationally, plus or minus your state's rate. All rows include the 10% cut-waste pros actually order.
