Start with filament cost
Calculate cost per gram from the spool price and usable weight. Then multiply by the grams used by the print.

Workflow
Step 1
Enter filament used
Step 2
Add spool cost
Step 3
Add electricity
Step 4
Add failure margin
Step 5
Review final estimate
Add print time and electricity
For long prints, include power usage and machine time so estimates reflect the real workflow more closely.
Add a failure margin
Complex prints, new materials, or unfamiliar printers deserve a failure margin. This keeps estimates realistic.
Use calculator results for decisions
A calculator is most useful when it helps you compare models, materials, scales, and whether a print is worth starting.
FAQ
Common questions
What inputs does a 3D print cost calculator need?
Filament used, spool price, electricity, print time, failure margin, machine cost, and labor if relevant.
How do I calculate filament cost?
Divide spool cost by usable grams, then multiply by the grams used by the print.
Should failed prints be included?
Yes, especially for business estimates or complex projects where failures are more likely.
Does PrintNext have a cost calculator?
Yes. PrintNext includes a 3D print cost calculator and inventory-aware planning tools.
