3D Print Selling Price Calculator

What does this calculator do?

Distinguish markup on cost from margin on revenue. Include design, rejects, packaging and fees in your declared cost basis.

How to use the calculator

1. Define the complete cost of one delivered item.
2. Choose whether the commercial target is a markup on cost or a margin on revenue.
3. Compare the two proposed prices and the resulting profit.
4. Check fees, discounts and tax treatment separately before issuing the quotation.

How the calculation works

Markup price = cost × (1 + markup% / 100). Margin price = cost / (1 − margin% / 100). Profit at margin price = margin price − cost. Fees and taxes are outside these outputs.

Practical calculation example

Understanding the results

Verify marketplace fee bases and tax treatment separately. A calculated price is a planning target and does not prove customer demand.

Choose the denominator before choosing the percentage

Margin and markup describe different relationships even when they use the same percentage. A markup compares profit with the cost of producing an item. A margin compares profit with the revenue received for that item. If you say that a job should earn thirty percent, you must decide which denominator you mean. This calculator shows both prices side by side rather than silently treating the terms as synonyms. Its cost input should represent your intended cost boundary for one deliverable, not merely the filament charge unless that is the comparison you deliberately want.

Derive the two price equations

With cost C and markup fraction u, the markup price is C multiplied by one plus u. With target margin fraction m, profit is price minus cost, and margin is that profit divided by price. Rearranging gives price equal to C divided by one minus m. Percentage inputs are converted to fractions internally. The margin must remain below one hundred percent for a finite result. Both equations use the same currency as the cost. Neither equation automatically adds tax, currency conversion, payment fees or an allowance for a discount you plan to offer later.

Work through the default comparison

A cost of 10 with a thirty percent markup produces a price of 13 and a profit of 3. That profit is only 3 divided by 13, or about 23.08 percent of revenue. A thirty percent target margin instead produces 10 divided by 0.70, or 14.285714. Profit is 4.285714, exactly thirty percent of that unrounded selling price. The difference is not a computational error: it comes from the different denominator. For an actual quote you might round a margin price to 14.30, then recompute the achieved margin if precision matters.

Build a complete cost basis

Use the print-cost workflow to assemble material, measured energy, machine occupation, maintenance, active labor and packaging before applying commercial pricing. If a bespoke model requires design work, decide whether it is billed separately or allocated to the expected order quantity. Include a defensible allowance for expected rejects without adding the same reserve twice. A reusable design sold repeatedly and a one-off commissioned object can have identical printing costs but very different design-cost allocation. Record that distinction in your quote so that future repeats are priced from their actual scope rather than blindly copying the first invoice.

Account for fees according to their real base

Some selling expenses are fixed per transaction; others are a fraction of revenue. A fixed amount can be added to the declared cost when its allocation is known. A percentage fee cannot generally be treated as the same percentage of production cost. If a revenue fee f and target margin m both use the same final revenue base, a simple extended model is price equal to cost divided by one minus f minus m. This calculator does not implement that extension. Verify the platform's actual fee basis, minimum charges and tax handling before using an external adjustment.

Discounts change the achieved margin

A price calculated for a target margin is not protected against later discounts. Starting with cost 10 and the thirty percent margin price of 14.285714, a ten percent discount leaves revenue of 12.857143. Profit falls to 2.857143 and the achieved margin becomes about 22.22 percent. Apply any planned discount to the proposed price, then check profit divided by the discounted revenue. If the required final revenue is fixed, calculate the undiscounted list price by dividing that revenue by one minus the discount fraction. Do not simply add the discount percentage to the required price.

Test the pressure from uncertain costs

The margin-price equation magnifies a cost change by the factor one divided by one minus the target margin. At a thirty percent target, every additional unit of cost requires roughly 1.429 units of price to preserve the margin. At a fifty percent target, the factor is two. This sensitivity is useful when a material supplier changes prices or a customer requests extra finishing. It also explains why a quote close to an implausibly high margin becomes unstable. Compare reasonable cost scenarios and check the resulting prices against demand; mathematical profitability does not guarantee that anyone will buy.

Keep price decisions separate from accounting claims

The displayed profit is the difference between the chosen selling-price model and the cost you supplied. It is not necessarily net business income after every overhead, tax or owner payment. State whether your cost already contains fixed overhead allocations and whether the quote includes shipping. Revisit assumptions when quantity, finish or turnaround changes. A batch discount should be justified by lower setup cost per item or other real savings, not by assuming that all individual costs fall with quantity. Save both the cost basis and the percentage convention so another person can reproduce your decision.

Advanced tips

• Write “margin on revenue” or “markup on cost” explicitly in internal pricing notes.
• Recompute the achieved margin after rounding or discounting.

Common mistakes

• Treating thirty percent markup as thirty percent margin.
• Applying a platform revenue fee to production cost instead of the actual fee base.
• Interpreting the displayed difference as fully audited net business profit.
