The average cost of carpet with padding and professional installation is $30 to $40 per square yard. Carpet ranges in price from a few dollars per square yard to $100 per square yard, depending upon the quality of carpet selected.
There are other factors that play into the price of carpet installation as well. Carpentry work to the sub floor or base boards can cost up to hundreds of dollars. Additionally, there can be other installation fees that are not readily apparent, charges for removal of old carpeting and charges for upgrades such as stain protection, pet protection and extended warranty.
