How to calculate the cost of a 3D print

The real cost of a 3D print is more than just plastic. This calculator adds up everything that goes into each print:

  • Filament cost = (spool price ÷ spool weight) × model weight. A $20 spool of 1 kg costs 2 cents per gram, so a 50 g print uses $1.00 of filament.
  • Electricity cost = printer power (kW) × print time (hours) × electricity price per kWh.
  • Machine wear = printer price ÷ expected lifetime in hours × print time. This covers nozzles, belts, build plates and eventually replacing the printer.
  • Failed print allowance: not every print succeeds. Adding 5–15% covers failed or wasted prints.
  • Labour and extras: time spent removing supports, sanding and painting, plus paint, magnets or packaging.

How much should I charge for 3D prints?

A common approach is to take your total cost and add a markup of 50–200%, depending on how much design, finishing and support work is involved. Painted cosplay pieces and custom work usually sell for far more than the raw material cost. Use the profit markup field to test different prices.

Frequently asked questions

How do I find the weight and print time of my model?

Slice the model in your slicer (Cura, PrusaSlicer, Bambu Studio, OrcaSlicer…). The weight in grams and the print time are shown after slicing. You can also get a quick estimate of the size and weight with our free online STL viewer.

How much electricity does a 3D printer use?

Most FDM printers use around 100–200 W on average while printing (more while heating up). A 10-hour print at 150 W uses about 1.5 kWh.

Does the calculator save my settings?

Yes. Your printer, filament and electricity settings are remembered in your own browser so you don’t have to type them again. Nothing is sent to our servers.

Can I use it for resin printers?

Yes. Enter the resin bottle price as the spool price and the bottle weight (or volume in ml, roughly the same as grams) as the spool weight.
