Formula and assumptions

How the calculator works

Cubic Yards = Length × Width × Thickness Inches / 12 / 27 × (1 + Waste %) Material Cost = Cubic Yards × Price Per Yard Estimated Cost = Material Cost + Labor/Prep Suggested Price = Estimated Cost / (1 - Target Margin)

Common mistakes this catches

  • Forgetting thickness visitor action from inches to feet.
  • Not adding waste or overage.
  • Leaving prep, forms, reinforcement, pump, finish, and disposal outside the quote.
