Calculate filament cost per gram and print material cost from a spool price and spool weight.
Open Filament Cost CalculatorInputs
| Spool price | $24 |
|---|---|
| Spool weight | 1000 g |
| Print weight | 85 g |
Outputs
| Cost per gram | $0.024 |
|---|---|
| Print material cost | $2.04 |
Formula Explanation
Cost per gram = 24 / 1000. Print material cost = 0.024 × 85.
Assumptions
- Spool weight means filament net weight.
- Shipping, tax, and waste are excluded unless you include them in spool price.
