3D Print Cost Calculator

Estimate what a print really costs from filament, spool math, print time, printer power, electricity rate, and optional markup.

Filament

Use slicer grams, or weigh the spool before and after.

Filament used

Purchased filament

Use this when the roll weight includes the empty spool. The app subtracts the empty spool weight to find the real filament cost per gram.

Go with spool before and after print weight

Filament used

Spool before print

Spool after print

Empty spool weight

Purchased spool weight

Filament purchase price

Waste / failed print allowance

Spool before weight must be higher than after weight.

Purchased spool weight must be higher than the empty spool weight.

Use your slicer time and printer wattage. A typical desktop printer is 80-180 W after heating.
