3D print cost calculator.
Know your real margin.
Turn your slicer numbers into a selling price that covers the work, the waste, and the fees.
Costs first.
Profit on purpose.
How is the price calculated?
Filament includes your waste allowance. Electricity and machine costs use the batch print time. The failed-batch reserve divides those production costs by your expected success rate. Labour and packaging are then added.
Selling price = (cost per item + fixed selling fee) ÷ (1 − percentage selling fee − target margin).
What does the failure rate mean?
A 10% failure rate assumes one in ten batches fails and uses the full material, power, and machine time. It reserves the cost of those failed attempts across successful batches. Adjust this to match your actual experience.
How should I enter marketplace fees?
Enter your effective percentage fee and any fixed per-item fee. Check your marketplace’s current terms. This simplified model assumes fees apply to the item price; shipping charges, taxes, advertising and currency conversion can add costs. Add any seller-paid shipping to packaging and fulfilment.
Are currencies converted?
No. The currency selector changes the labels only. Enter all costs in the same currency. Results are estimates before income tax and sales tax; they do not include a live marketplace fee schedule.
Should I enter one item or the whole batch?
Enter the weight, print time and hands-on labour for the whole batch. Then enter the number of items. Packaging and fixed selling fees are per item.
Does filament weight include supports and purge?
Use the full material consumed when available. If the slicer already includes supports and purge, do not add them again through the waste percentage.
What is the difference between margin and markup?
Margin is profit divided by selling price. Markup is profit divided by cost. The target in this calculator is margin after the costs and fees you entered.
Why is the failure allowance more than the failure percentage?
The calculator divides production costs by the expected success rate. A 10% full-batch failure rate increases those costs by 1 ÷ 0.90, or about 11.11%.
