Filament Cost Calculator — Material Cost per Print
Work out the material cost of a print based on filament weight used and spool price.
Filament weight from slicer
How We Calculate This
Formula
- Cost per gram = Spool price / Spool weight
- Print cost = Print weight x Cost per gram
- Prints per spool = Spool weight / Print weight
This gives you the raw material cost only. For total print cost including electricity and wear, use our Print Cost Calculator.
