It depends on the type of carpet, the quality of carpet, and the size of the room. Carpet installation can cost anywhere from $100 to $1,000 per room.

There is no one-size-fits-all answer to this question. The cost of carpet installation will vary depending on the size and complexity of the project, as well as the type of carpeting and installation methods used. That said, a general rule of thumb is that you can expect to pay around $2 to $5 per square foot for professional carpet installation. So, for example, if your room is 10'x10', you can expect to pay anywhere from $200 to $500 for installation.
