Formula and assumptions

How the calculator works

Materials With Waste = Materials Before Waste × (1 + Waste %) Labor Cost = Labor Hours × Labor Rate Subtotal = Materials With Waste + Labor + Subs + Equipment + Permits + Travel + Overhead Contingency = Subtotal × Contingency % Total Job Cost = Materials With Waste + Labor + Subs + Equipment + Permits + Travel + Overhead + Contingency Suggested Price = Total Job Cost / (1 - Target Margin)

Common mistakes this catches

  • Adding waste to materials but not pricing it.
  • Forgetting permits, disposal, rentals, fuel, or trip costs.
  • Using wage instead of loaded labor rate.
  • Leaving overhead and contingency outside the job price.
