Setup cost (fixturing, programming, tooling setup, first-article inspection) is fixed regardless of batch size. Spreading $200 setup over 10 parts adds $20/part; over 1,000 parts it adds only $0.20/part.
EBQ balances setup cost amortisation against inventory holding cost. For most CNC job shops, the practical EBQ is driven by customer order quantity and machine schedule, not theoretical optimisation formulas.
Yes. The processing cost should include the fully burdened machine rate (operator + machine depreciation + electricity + coolant + floor space). Typical CNC machine rates range from $60-150/hour depending on the machine type and region.
Enter the batch quantity, material cost per part, setup cost, and processing cost per part. The calculator shows total batch cost and cost per unit. Use it to compare quotes or optimise batch sizes.

Use the calculator freely. If the result points to a tooling or process problem, we can source the exact carbide tooling you need from vetted factories in China. Compare factory-direct pricing.
Before you commit to a spec, it helps to know what the market pays for it. These are real, publicly listed factory prices — not a quotation, and not a guess.
We source the tool families below direct from vetted Chinese factories, matched to the material and tolerance you just worked out. Every batch ships with its material certificate and dimensional record.
