Calculating Laser Cutting Cost In Actual Work

Let’s consider cutting a 4ft x 8ft sheet of stainless steel (304 grade) that’s 0.25 inches thick. The material cost is $5 per square foot. The machine setup cost is $100 per hour, and the cutting speed is 50 inches per minute. The machine’s operational cost is $20 per hour, and the estimated cutting time for the design is 2 hours.

  • Material Cost = 4ft x 8ft x $5/sq ft = $160
  • Machine Setup Cost = $100
  • Cutting Time Cost = 2 hours x $20/hour = $40
  • Machine Operational Cost = 2 hours x $20/hour = $40

Total Cost = Material Cost + Machine Setup Cost + Cutting Time Cost + Machine Operational Cost = $160 + $100 + $40 + $40 = $340
