3D print cost calculator

Work out what an FDM print costs and what to charge. Start with the slicer numbers, then add failed prints, your time, packing and fees. Free to use. No account needed.

The numbers below are a sample job. Replace them with yours. Keep all money inputs in the same currency: the selector changes the label, not the exchange rate.

How these numbers are worked out

Attempt costs are multiplied by quantity ÷ (1 − failure chance). This conservative model assumes a failed attempt uses the full material, print time and reset labor. Setup is once per order. Finishing and packaging apply only to successful parts.

Pre-tax price = (modeled cost + fixed fee) ÷ (1 − target margin − fee rate × (1 + output tax rate)). The total is rounded up to the next cent. Contribution excludes income tax and unentered costs.
