Pinnacle Contractor Calculator

Drywall Calculator

Calculate drywall for multiple rooms and ceilings — standard, moisture-resistant baths, or double-layer 5/8" commercial fire-rated assemblies.

This is an estimate, not a bid or contract. Every job has unique conditions — access, structure, moisture, code — that software cannot account for.

Use at your own risk. Pinnacle Designs, LLC is not liable for bids, losses, or code compliance based on calculator output. You are responsible for verifying all numbers before use.

Terms of Service (limitation of liability & your responsibilities)

Always verify local building codes. Supplier prices vary by region. Add waste for cuts, mistakes, and damaged material.

Job Site Market (ZIP & Region)

Enter the job ZIP — not your shop — to load typical local labor and material defaults. Useful when bidding out of town or out of state.

Most U.S. ZIPs auto-select a region. Unknown ZIPs — pick the closest market manually.

Typical U.S. contractor rates, loaded ~5% above market average — adjust for your bid.

National Average — typical contractor labor ~$57.75/hr

Typical labor rates align with the national average.

Defaults load ~5% above typical market averages — a conservative benchmark when clients compare your bid. Edit any rate below for your actual numbers.

Regional defaults update labor, materials, markup, and tax in this calculator. Your job ZIP and region are saved across all calculators — change ZIP when you switch to a different job site.

Estimate — not a bid

Numbers from this tool are planning estimates only. They are not a contract, quote, binding bid, or professional advice. Every job carries its own challenges — hidden damage, tight access, moisture, local code, and scope details — that no calculator can see.

Each project is different. Access, existing conditions, code requirements, material choices, and your local market all affect the final price. Use these figures as a starting point — your actual price may vary.

By using this tool you agree you will not rely on it as a final bid without your own verification. See our Terms of Service for limitations of liability and your responsibilities.

How this was calculated
  1. Per room: wall SF = perimeter × height − door/window deductions
  2. Ceiling SF added when enabled per room
  3. Screws: ~32 per 4×8 wall sheet (16" o.c.), ~36 per ceiling sheet (12" o.c.) — GA/IRC spacing
  4. Double-layer fire-rated rooms multiply screw count for both layers
  5. Tape ~1 roll per 800 SF; mud ~1 bucket (4.5 gal) per 400 SF
  6. Commercial fire-rated = double layer 5/8" Type X (×2 sheets)

Frequently Asked Questions

When do I use commercial fire-rated?
Schools, hospitals, and many commercial corridors require two layers of 5/8" Type X drywall. Always verify local fire code and inspection requirements.
How many drywall screws do I need?
Plan about 32 screws per 4×8 wall sheet (16" o.c. in the field) and 36 per ceiling sheet (12" o.c.). A typical 12×12 room with 8' walls and ceiling is roughly 500–600 screws — about one 1,000-count box for two similar rooms.
What about bathrooms?
Select Bathroom / Moisture Area for green or purple board in wet zones. Cement board is still required behind tile in showers — add that separately.

Drywall Calculator — Sheets, Mud, Tape & Finish Labor

Drywall quantity depends on wall and ceiling square footage, sheet size (4×8, 4×10, or 4×12), and waste for cuts around openings. This calculator estimates sheet count, screws, joint tape, mud, corner bead, and finishing labor for Level 4 or Level 5 finishes.

Add multiple rooms or use measurements from your framing takeoff. Set your local sheet price, mud cost, and labor rate per square foot to generate a client-ready price with overhead and markup included.
