3D Print Filament Cost Calculator

Price two materials separately and check how many separate repeat prints can be made from a weighed spool after a reserve.

Enter your values

Main material
Second material · optional

Enter 0 grams if there is no second material. Include each material's supports and purge waste once.

Separate remaining-filament check · g

This check applies to this spool only; it does not combine the materials above. Use one currency for all prices.

Material cost excludes power, labor, machines and failures. Remaining prints use a separate weighed-spool example; re-slice multi-item batches.

How it works

For each material, cost = total grams for this print × full spool price ÷ net filament grams. Include supports, skirts and purge material once. Net filament weight excludes the empty spool. Enter all prices in the same currency. The remaining-filament check is independent of the two-material cost calculation.

Scope & limitations

Usable grams = gross weight − empty spool weight − reserve. Complete repeat prints = floor(usable grams ÷ grams per print). Empty spool weights vary; measure yours. Re-slice a multi-item batch because supports and purge use may change. The result excludes power, labor, machine depreciation, failures and finishing; it is not a customer quote or profit estimate.
