3D Printer Electricity Cost Calculator
3D printers use far less power than their power supply rating suggests. Work out kWh and cost per print, and per month.
Estimates only. Check numbers against your own slicer, scale and electricity bill. Some links on this page may be affiliate links.
Formula
kWh = watts ÷ 1000 × hours. Cost = kWh × your price per kWh. Monthly = cost per print × prints + standby watts ÷ 1000 × standby hours × price. Example: 105 W for 10 h at $0.20/kWh = 1.05 kWh = $0.21.
Average printer power
| Printer | PLA average | Notes |
|---|---|---|
| Bambu X1 / X1C | 105 W | ABS ~150 W |
| Bambu P1S | 105 W | ABS ~140 W |
| Bambu P1P | 110 W | |
| Bambu A1 | 95 W | ABS ~200 W |
| Bambu A1 mini | 80 W | PETG ~75 W |
| Generic FDM | 100–150 W | Estimate — measure with a plug-in meter |

FAQ
How much electricity does a 3D printer use?
Typically 80–150 W on average while printing PLA, so a 10-hour print uses about 1 kWh.
Does ABS use more power?
Yes. Higher bed and nozzle temperatures raise average draw, e.g. about 140–150 W on a Bambu P1S or X1C.
What should I use for my electricity price?
Use the per-kWh price on your bill, including taxes. In South Africa many municipal tariffs are roughly R2.50–R4 per kWh; check yours.
