Formula and assumptions

How the calculator works

Sheets = Ceiling(Drywall Area × (1 + Waste %) / Sheet Area) Sheet Cost = Sheets × Cost Per Sheet Labor Cost = Area × Labor Rate Suggested Price = Total Cost / (1 - Target Margin)

Common mistakes this catches

  • Counting only wall area and forgetting ceilings.
  • Ignoring waste, odd cuts, corners, bead, tape, mud, sanding, cleanup, and texture.
  • Using the same labor rate for patch work and large open rooms.
