Separate fixed setup, variable production, waste, labor, overhead, finishing and delivery. The lab shows the raw cost per sellable piece, proposed selling price and break-even quantity without pretending your rates are universal.
Start with the quantity you expect to deliver. Waste is added to the produced quantity so material and variable production costs do not quietly ignore spoilage.
Change one assumption at a time to see which part of the job controls the unit cost.
| Cost component | Amount | Share | Basis |
|---|
If spoilage increases produced pieces, every per-produced-piece cost can rise with it: substrate, click charges, ink coverage assumptions or outsourced production. Finishing may instead apply only to accepted pieces. Keep those bases separate rather than multiplying the whole job by one blanket waste factor.
A 35% markup on cost means price equals cost × 1.35. That does not create a 35% gross margin on selling price. The lab deliberately labels markup so commercial targets are not silently mixed. Use the financial convention your business actually follows.
Break-even is meaningful only when fixed and variable costs are separated. Here setup, labor, overhead and shipping are treated as fixed for the modeled run while material, machine and finishing are variable. If your labor or delivery behaves differently, change the inputs or treat the output as a rough planning scenario.
