Laser cutting quotes often fail because they use area as a proxy for time. A large simple shape may cut faster than a smaller design filled with tiny interior cuts. The reliable method is to estimate production time, material yield and handling for the actual file.
Step 1: Estimate machine minutes
Use your software's estimated time as a starting point, then compare it with real runs for the same material and settings. Add loading, focusing, positioning, testing and unloading time. Track setup separately if it applies to the whole order.
Step 2: Calculate material yield
Divide the usable sheet area by the parts per sheet after spacing and waste. Include edge trim, support tabs, failed cuts and offcuts that cannot be used for another product. If one sheet yields eight parts but ten are attempted, the cost per sellable part must include the two unsuccessful positions.
Step 3: Add finishing and packing
Smoke residue, masking removal, sanding, edge treatment, assembly and protective packing can consume more labor than the cut itself. Record those tasks in the same way you record laser time.
Step 4: Include the sales channel
On a marketplace, a percentage of the sale price is retained. If a fixed payment fee also applies, include it once per transaction rather than once per item. Then reserve the target profit margin.
A compact cutting estimate
Machine cost = total machine minutes ÷ 60 × machine hourly rate
Labor cost = total labor minutes ÷ 60 × labor hourly rate
Total order price = (direct costs + fixed fees) ÷ (1 − percentage fee − target margin)
The same structure works for engraving, cutting or a mixed job. What changes is the production time, material yield and finishing work.
When to quote from time and when to quote per part
Time-based pricing is useful for custom work and unfamiliar files. Per-part pricing is easier for repeatable products with a stable design and material. Even with a per-part list price, recalculate the underlying batch occasionally so the familiar number does not silently become unprofitable.
