Average cost of a new drywall to get installed will vary from $41.5 to $60.0 per 4'x8'x5/8 sheet including labor and materials or from $1.30 to $1.88 per square foot.
Labor Cost. Installers will determine the drywall prices by how much labor it will take to hang and finish the total finished area. They will then add in whatever profit they think is reasonable, and divide the total by how many sheets they will actually install and finish. Hence, the cost-per-sheet. You can pay for anywhere from $25 a sheet ($12.50 to hang, and $12.50 to finish) on the cheaper side, on up the scale to as much as $60 a sheet to finish drywall for the pricier projects such as wide arches, vaulted ceilings, etc.
