Compare two user-entered material prices for the same print weight before adding labor or markup.
Open Filament Cost CalculatorInputs
| PLA spool | $22 per 1000 g |
|---|---|
| PETG spool | $28 per 1000 g |
| Print weight | 120 g |
Outputs
| PLA material cost | $2.64 |
|---|---|
| PETG material cost | $3.36 |
| Difference | $0.72 |
Formula Explanation
PLA = 22 / 1000 × 120. PETG = 28 / 1000 × 120. Difference = PETG - PLA.
Assumptions
- Both materials use the same print weight.
- Print time, failure rate, and tuning differences are excluded.
