Profit on a 3D printed product is what remains after you cover every real cost — not “selling price minus filament.” This guide separates cost, revenue, markup, and margin, then walks an illustrative example you can rebuild with your own numbers.
Use the Product Pricing Calculator for a full stack. Building blocks: Filament Cost Calculator, Print Cost Calculator, and the print cost guide. Examples below are illustrative, not guaranteed results.
Cost vs revenue vs profit
- Revenue = selling price × quantity sold
- Total cost = direct costs + allocated overhead (for that job or batch)
- Profit = revenue − total cost
- Profit margin = profit ÷ revenue × 100
- Markup = profit ÷ cost × 100
If you only track filament, you are measuring material — not profit.
Direct costs
Direct costs move with the job: filament (and purge/supports you include), electricity for that print, labour/setup minutes, packaging for that unit, and shipping if you charge per order. Start material with the Filament Cost Calculator.
Machine cost and depreciation
Pick either a simple hourly machine rate or printer depreciation (purchase cost ÷ expected lifetime hours × print hours). Using both double-counts the machine. The pricing calculator forces one method for that reason.
Labor
Include slicing, bed prep, supervision, part removal, cleanup, and packing — not only “the printer ran for four hours.” Even a short setup at your hourly rate changes the quote.
Failure rate and waste
Failed prints, wasted purge, and reprints are real. A common approach is a failure/waste % on the production base (material + machine + electricity + labour). If you ignore it, successful jobs silently subsidise failed ones.
Packaging and shipping
Cartons, fillers, labels, and courier minimums belong in cost or as a separate line on the invoice. Free shipping is not free — it comes out of margin.
Overhead
Rent, tools, software, website fees, and miscellaneous consumables. Allocate a share per job (simple ₹ amount) or refine later with monthly totals ÷ jobs. Rough allocation beats zero.
Margin vs markup
Markup is profit divided by cost. Margin is profit divided by selling price. A 40% markup is not a 40% margin. Confusing them underprices jobs. For one unit: markup price = cost × (1 + markup%); margin price = cost ÷ (1 − margin%).
Worked example (illustrative)
Suppose one desk organiser: material ₹100.80, machine ₹112.50, electricity ≈ ₹4.32, labour ₹50. Production base ≈ ₹267.62. Failure 8% ≈ ₹21.41. Packaging ₹15 + overhead ₹20. Total cost ≈ ₹324.03.
At 40% markup: selling price ≈ ₹453.64. Profit ≈ ₹129.61. Effective markup 40%; effective margin ≈ 28.6%. Sell two units: revenue ≈ ₹907.28; if both succeed at the same unit cost, profit scales — but real batches still need failure and shipping reality checks. Replace every figure with yours.
How to use the RB3DLabs Product Pricing Calculator
- Enter material ₹ (from the filament tool if needed) and optional grams for notes
- Enter print time; choose hourly machine rate or depreciation
- Add power, labour, packaging, shipping, overhead, failure %
- Choose markup or target margin and read cost, break-even, profit, and selling price
- Hit Reset example only to restore sample defaults — then overwrite them
Open the Product Pricing Calculator. For simpler power + markup jobs, the Print Cost Calculator still helps.
Common pricing mistakes
- Selling at material cost and calling it “competitive”
- Mixing markup and margin percentages
- Double-counting machine hourly rate and depreciation
- Ignoring failure, packing, and unpaid setup time
- Assuming marketplace fees or GST will “sort themselves out”
