Why is filament-only pricing wrong?

Filament is often a minority of true cost. Electricity, labor, failures, and machine wear usually dominate seller economics.

What electricity rate should I use?

Use your blended residential or shop $/kWh from the utility bill. US defaults in this tool start near $0.16/kWh and are editable.

How this is calculated

material = grams × (1 + waste) × (spool$/spoolGrams); electricity = kW × hours × $/kWh; depreciation = (printer$ / lifetimeHours) × hours; labor = hours × rate; trueCost = subtotal × (1 + failureBuffer).
