3D Print Batch Pricing uses estimated total cost, target margin (%), marketplace fee (%).
Making a print estimate reflect the work behind the part
For 3d print batch pricing, the relationship is Selling price = (production cost + shipping) ÷ (1 − (target margin% + selling fee%) ÷ 100). Fees and margin must total less than 100%. The amount depends on the supplied estimated total cost, target margin (%), rather than a live market price or a value imported from another record. Filament cost is only one component of a printed part. Machine time, failed jobs, setup, labour and fulfilment can materially change contribution. Compare grams with the usable spool weight, rather than the label price alone.
What the model includes
Selling price = (production cost + shipping) ÷ (1 − (target margin% + selling fee%) ÷ 100). Fees and margin must total less than 100%. Use measured print duration where possible and keep machine-hour charges separate from electricity. If the machine rate already includes energy or labour, entering those amounts again double counts them. The model cannot infer a failure rate from a successful test print. A quote still needs the part requirements and production method. Material choice, orientation and finishing affect quality; this estimate does not establish mechanical suitability or guarantee the print will succeed.
Example with the supplied inputs
Estimated total cost: 25; Target margin (%): 35; Marketplace fee (%): 10; Shipping charged to seller: 5. Result: 54.5455. The values are illustrative.
Compare one changed input
Estimated total cost changes from 25 to 27.5. The result becomes 59.0909. All other inputs remain fixed.
Calculation rule
Selling price = (production cost + shipping) ÷ (1 − (target margin% + selling fee%) ÷ 100). Fees and margin must total less than 100%.
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Estimated total cost | 25 | Use estimated total cost on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
| Target margin (%) | 35 | Enter target margin (%) on the percentage scale used in the formula (20 means 20%, not 0.20). Keep its base and reporting period consistent with the other inputs. |
| Marketplace fee (%) | 10 | Enter marketplace fee (%) on the percentage scale used in the formula (20 means 20%, not 0.20). Keep its base and reporting period consistent with the other inputs. |
| Shipping charged to seller | 5 | Use the source quantity represented by shipping charged to seller. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 54.5455 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Estimated total cost, Target margin (%), Marketplace fee (%). Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Estimated total cost on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 54.5455.
Change Estimated total cost from 25 to 27.5 while keeping every other value fixed. The result becomes 59.0909. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
