The Drywall Finishing Cost for a Room calculator estimates the cost to finish drywall in a room based on the dimensions of the room and the cost per unit (4x8) for finishing. Dimensions of a Room

INSTRUCTIONS: Choose units and enter the following:

• (L)  This is the length of the room.
• (W) This is the width of the room.
• (H)  This is the height of the room.
• (PPS)  This is the finishing price per drywall (4x8) sheet.

The Math / Science

The cost to finish drywall calculator:

1. computes the surface area of the room including the walls and ceiling,
2. divides the area by 32 square feet for a 4x8
3. multiplies the number of sheets calculated above by the price per unit for finishing.

Note: in 2019 the U.S. national average for drywall finishing ranged between $45 to $70 per 4x8 sheet.
