Filament Cost Calculator
Calculate the exact material cost of any 3D print based on filament price per spool and usage.
How It Works
Enter the weight of filament used, your spool size, and spool price. The calculator determines what fraction of the spool you used and multiplies by the spool cost to get the material cost per print.
Formula
Cost = (Filament Used (g) / Spool Weight (g)) x Spool Price ($)
Frequently Asked Questions
How do I know how many grams I used?
Your slicer software estimates grams before printing. You can also weigh the spool before and after printing.
Does this include electricity cost?
No, this calculates material cost only. Use the electricity cost calculator for power costs.
