3D Printing Cost Calculator

Estimate the cost of a 3D print.

Filament used

Filament price ($/kg)

Print time

Printer power (W)

Electricity price ($/kWh)

Calculated Output

Total cost ($) 3.18

Material cost ($) 3

Energy cost ($) 0.18

Formula: cost = filament cost + energy cost

Step-by-Step Breakdown

1. Values used:

2. Filament used = 120

3. Filament price = 25 $/kg

4. Print time = 8

5. Printer power = 150 W

6. Electricity price = 0.15 $/kWh

8. Total cost = 3.18$

9. Material cost = 3$

10. Energy cost = 0.18$

Did this calculator solve your problem today?

The math behind it

material = filament g ÷ 1000 × price/kg; energy = power kW × hours × price/kWh.

120 g at $25/kg, 8 h, 150 W → ~$3.18.

Machine wear?

Add a small amortization fee per hour for the printer and nozzle.
