Does this laser cutting cost calculator choose a cutting speed?+
No. Enter an effective speed from your process data or equipment supplier. Material, thickness, gas, laser power and geometry matter; the default speed is an arithmetic example, not a process recommendation.
Do I enter total batch length or length per part?+
Enter cut path per part. The calculator multiplies it by the part count. Include internal holes and slots as well as the outside contour, but do not multiply by batch quantity yourself.
Is material waste the same as nesting utilization or reject rate?+
No. This input is an added material-cost percentage. At 80% nesting utilization, the equivalent cost allowance is 25%, because 1 ÷ 0.8 − 1 = 0.25. It does not add machine time or replacement parts for rejects.
Is the estimate a selling price?+
No. It estimates the machine and material costs entered, excluding profit, tax, shipping and unentered finishing work. Your all-in hourly rate should cover labor, energy, assist gas and the shop overhead you want included. Request a supplier quote for a purchase or outsourced job.
