Drywall Cost Estimator
Estimate drywall cost for your project with our free calculator. Get accurate material quantities, costs, and specifications.
Formula
Total Cost = (Sheets x Price) + Supplies + (Area x Hang Rate) + (Area x Finish Rate)
The total drywall cost combines material costs (sheets based on net wall area plus 10% waste, plus supplies like tape, compound, and screws) with labor costs (hanging rate plus finishing rate per square foot, which varies by finish level). A 10% deduction for windows and doors is applied to gross wall area.
Worked Examples
Example 1: Single Room Drywall
Problem: Estimate drywall cost for a room with 50 linear feet of walls, 8 ft ceiling height, using regular 4x8 sheets with Level 4 finish.
Solution: Wall area = 50 x 8 = 400 sq ft\nNet area (90%) = 360 sq ft\nSheets = 360 x 1.1 / 32 = 13 sheets\nMaterial: 13 x $12 + supplies = $283\nLabor: 360 x ($1.75 + $2.50) = $1,530\nTotal = $1,813
Result: Total cost = $1,813 ($5.04/sq ft)
Example 2: Basement Moisture-Resistant Drywall
Problem: Estimate cost for a basement with 120 linear feet of walls, 8 ft height, moisture-resistant 4x8 sheets, Level 4 finish.
Solution: Wall area = 120 x 8 = 960 sq ft\nNet area (90%) = 864 sq ft\nSheets = 864 x 1.1 / 32 = 30 sheets\nMaterial: 30 x $16 + supplies = $769\nLabor: 864 x ($1.75 + $2.50) = $3,672\nTotal = $4,441
Result: Total cost = $4,441 ($5.14/sq ft)
Frequently Asked Questions
How much does drywall installation cost per square foot?
Drywall installation typically costs $1.50 to $3.50 per square foot for standard 1/2-inch drywall with a Level 4 finish, including materials and labor. Hanging drywall alone costs about $1.00 to $1.75 per square foot for labor, while taping and finishing adds another $1.50 to $3.00 per square foot depending on the finish level. Specialty drywall like moisture-resistant or soundproof panels costs 30-100% more for materials. Ceiling work costs 10-25% more than wall work due to the difficulty of overhead installation.
What are the different drywall finish levels?
Drywall finish levels range from Level 0 to Level 5 as defined by the Gypsum Association. Level 0 is no finishing at all. Level 1 has taped joints with compound embedded, used in above-ceiling areas. Level 2 adds a thin coat of compound over tape and fasteners, suitable for garages. Level 3 has two coats of compound and is adequate for textured walls. Level 4 has three coats of compound and light sanding, standard for smooth painted walls. Level 5 adds a skim coat over the entire surface for the highest quality flat-paint finish.
How do I estimate the number of drywall sheets needed?
Calculate the total wall area by multiplying the perimeter of each room by the ceiling height, then subtract approximately 10% for windows and doors. Divide the net area by the sheet size (32 sq ft for 4x8, 40 sq ft for 4x10, or 48 sq ft for 4x12 sheets) and add 10% for waste from cutting and fitting. Using longer sheets that match your ceiling height reduces the number of horizontal seams and speeds up installation. For 9-foot ceilings, use 4x10 sheets; for 10-foot or higher ceilings, use 4x12 sheets.
What supplies are needed besides drywall sheets?
In addition to drywall panels, you need joint tape (paper or mesh), joint compound (premixed or setting type), drywall screws (coarse thread for wood framing, fine thread for metal studs), corner bead for outside corners, and sandpaper or sanding sponges. A typical room requires one roll of joint tape per 300 sq ft, one 4.5-gallon bucket of compound per 100 sq ft, and one box of screws per 8 sheets. Other tools include a drywall T-square, utility knife, screw gun, mud pan, and taping knives in 6-inch, 10-inch, and 12-inch sizes.
