The number of stairs you want carpeted in your home will directly affect your carpet installation cost. Putting carpet on stairs generally increases the labor time and requires a higher degree of detail than laying carpet flat. Where you live in the country also plays a role in your carpet installation cost. Carpet installation companies in smaller towns with a lower cost of living and a lower cost to do business (insurance, company vehicles, employee labor, etc.) can usually offer their customers lower rates than companies in large cities where the cost of living and the cost to do business are higher. Carpet pros will often quote you a flat rate per stair once they do a site visit to provide an estimate. They’ll take into account the size of each stair you want carpeted (including both the step and the riser), and what type of stair it is. For example, the cost might range between $3 and $10 per stair for labor only. On the higher end of the spectrum, box stairs or staircase stairs with spindles that must be worked around might cost between $15 and $25 per stair.

If you’re building a new home, remodeling, or ready for new carpet in your bedroom, you’ll want to know carpet installation costs. Here are the factors that affect the cost of your new bedroom carpet:

• Installation cost per square yard: From under $2 to over $6. Carpet companies have a labor cost per square foot for installing your new carpet. Depending on where you live in the country, that rate can vary greatly. This rate does not include the cost of the carpet.
• Type of carpet: from $1 per square foot to $20 or more per square foot. The fibers that make up your carpet will have a direct effect on cost. As an example, specialty wool carpets may start at about $10 per square foot, while a manufactured fiber like nylon may be about $2 per square foot.
• Removal of old carpet: from $1 to $4 per square yard. Old carpet is labor-intensive to remove and also costs money to dispose of or recycle. The cost to remove carpet will depend on how much carpet you need removed and whether your installation pros offer a discounted rate for installing your new carpet at the same time.
• Subfloor repair: from $40 to $70 per hour (plus materials cost). If the flooring underneath your old carpet is damaged, it must be repaired before the new carpet is installed. Many carpet pros can offer this service, or you can hire a handyman to handle the job.  
• Type of carpet pad: $1 per square yard and up, depending on the thickness. The cost to install carpet pad is typically included with the labor cost per yard of installing the carpet itself.

If you’re ready to bring new life into your house with a makeover from the ground up, you’re ready to learn more about carpet installation costs. Installation costs vary greatly, depending on a number of factors such as the type of carpet, the number of square yards, any necessary repair work, the number of stairs you have, and where you live. Due to these variables, the national average cost of carpet installation ranges between $200 and $4,500.

To start planning for your new carpet, measure roughly how many square yards of carpet you’ll need. Research the main carpet styles and materials you like to get a feel for what they cost. Nylon carpets are typically the least expensive, and wool is one of the higher-end carpets. Prices per square foot might range from under $2 to over $10, depending on materials. Count the number of stairs you want carpeted; each one might average between $3 and $10 (or more for box steps). Carpet removal can be an added cost as well, averaging $1-$4 per square yard, depending on the company and regional disposal costs. 

If you’re looking to reduce carpet installation costs, there are several ways to save. Start by considering your carpeting needs. Manufactured materials such as polyester and nylon will be cheaper than natural fibers such as wool. From big box retailers, starting prices for olefin-based carpet are approximately 50 cents per square foot — making the cost under $5 per square yard. Indoor carpets made with olefin fibers are typically the least expensive on the market. Keep in mind that olefin fibers are not as soft on bare feet as other fibers, so are often used in areas like basements, playrooms or indoor patios. Nylon and polyester are good options to reduce carpet installation costs while still creating a cozy feel. The face weight, fiber construction and density of a carpet all affect the cost per square foot. The cheapest nylon or polyester carpets can start at just under $2 per square foot, making them about $18 per square yard. Lower-cost carpet tends to wear out more quickly and show stains more easily, so avoid light colors and vacuum regularly to keep the fibers clear of dirt that might age it too quickly.
