Before you begin
A fictional or completed batch record with time, material, rejected units, and packaging. Example dollars are not market recommendations.
What this lesson covers
- Include artwork, setup, cleanup, and fulfillment in the cost model.
- Use saleable quantity when allocating incurred batch costs.
- Separate a reusable base product from custom design work.
Recommended preparation
01 / Key concepts
How it works
A fast laser cycle can make a product look inexpensive to produce, but the business still has design, setup, test runs, material, finishing, fulfillment, and selling costs to recover.
- Accepted yield
- The proportion of produced items that meet the stated acceptance criteria.
- Unit cost
- The chosen total incurred cost divided by accepted units, with the cost scope stated.
Include preparation and finishing time
Artwork setup, material preparation, masking, cleanup, finishing, photography, packaging, messages, and fulfillment can be a larger time cost than the engraving run.
Use a repeatable production baseline
Time a small batch from blank material to packed order. That gives you a real baseline for a template product and shows whether the process needs a jig or fixture.
Keep custom requests separate from standard products
Estimate personalization, new artwork, revisions and customer communication separately. Define what the standard product includes so additional work is priced consistently.
Key points
- The machine pass is not the entire product cost.
- Setup, artwork, masking, cleanup, finishing, photos, packaging, and messages take real time.
- Use measured time and material consumption to establish a base product cost.
02 / Worked example
Unit cost after two rejected items
Illustrative batch costs total $120 for 20 blanks, including this example's material, artwork, labor, machine recovery, and packaging. Two items are rejected. Selling fees, shipping, tax, and profit are outside the example.
| Measure | Calculation | Result |
|---|---|---|
| Accepted quantity | 20 − 2 | 18 items |
| Accepted yield | 18 ÷ 20 | 90% |
| Cost per accepted item | $120 ÷ 18 | $6.67 rounded |
| Misleading blank-based cost | $120 ÷ 20 | $6.00; ignores rejected output |
Calculate the cost of rejected items
Keep the batch cost fixed and increase the rejected quantity to see how the cost of each accepted item changes.
All batch costs entered here are already incurred. This calculates cost, not a selling price, and does not add fees, shipping, taxes, or profit.
20 − 2 = 18 accepted items (90.0% yield). $120 ÷ 18 = cost per accepted item.
03 / Workshop exercise
Apply the method
Work through the drawing or setup review first, then use a sample that matches your project. Check the equipment and safety requirements above before starting any machine work.
- Make one product from blank material to packed order.
- Track every minute before and after the laser run.
- Use the full time and material result to create a repeatable base price.
Common mistakes
- Pricing from material plus a few machine minutes.
- Giving custom design work away inside a standard item price.
- Forgetting packaging, platform fees, rework, and waste.
Take it further
Build a batch review showing accepted quantity, rework cause, full time, unit cost, and the next improvement. Keep quality criteria constant while comparing batches.
Workshop checklist
Use this topic checklist alongside your machine’s full setup procedure.
- Track the full production and fulfillment cycle.
- Include materials, waste, machine time, packaging, platform fees, and labor.
- Test a small repeatable batch before scaling.
- Separate custom design or rush work from the base product.
- Review actual profit after a completed sale or batch.
04 / Review questions
Review the key decisions
Consider each question, then compare your answer with the explanation. Return to the worked example whenever you need it.
1. If accepted output falls to 15 while cost stays $120, what is the unit cost?
View hint
Use the accepted quantity as the denominator.
View explanation
$120 ÷ 15 = $8 per accepted item. This does not yet include costs excluded from the example or a profit allowance.
2. Should every personalized order inherit the base item's artwork time unchanged?
View hint
Repeat production and new design are different work.
View explanation
No. Separate reusable setup from new artwork, revisions, and approvals. Record what is included in the base product and estimate the actual additional work.
