How It Works
Enter your print weight and the cost of each spool. The calculator ranks materials by cost per gram and total print cost so you can choose the most economical option.
Formula
Cost per gram = Spool Price / Spool Weight
Frequently Asked Questions
Which filament is cheapest?
PLA is generally the cheapest common filament at $15-25/kg. PETG is slightly more at $20-30/kg. Engineering materials like Nylon or PC cost $40-100/kg.
Does density affect cost comparison?
Yes. Denser materials (like PETG at 1.27 g/cm3 vs PLA at 1.24) use slightly more mass for the same volume, increasing cost by a small amount.
