3D Print Filament Cost Calculator

The problem: You sell or gift 3D prints but have no idea what one actually costs you — filament, electricity and time all blur together.

How to use — quick guide

Read the grams of filament your slicer reports, then enter them into this 3d print cost calculator along with your spool price and weight, printer wattage, print hours and electricity rate. It adds filament and power together and shows the true cost of each print, so you can price fairly. Free and no signup needed.

How to use it

  1. Enter the grams of filament the slicer says the print uses.
  2. Add your spool price and weight, your printer's wattage, print hours and electricity rate.
  3. You get the true cost per print — filament + electricity — so you can price fairly.

Frequently asked questions

Where do I find grams used?

Your slicer (Cura, PrusaSlicer, Bambu Studio) shows filament used in grams on the preview screen.

How many watts does a printer use?

Typical FDM printers draw 80–150 W while printing. Check your PSU label or a plug-in power meter.

Should I add machine wear?

For selling, yes — many makers add 10–20% for nozzles, build plates and failures.
