How to use this calculator

Pick your country and the calculator fills in an average residential electricity rate and switches the currency to match — the built-in rates cover the United States, United Kingdom, Germany, Japan, Australia, Canada and France and are refreshed quarterly. If you know your exact rate from your utility bill, choose "Custom rate" and type it in; tiered and time-of-use tariffs make real rates vary a lot within one country.

The wattage field wants the average draw during a print, not the number on the power supply label. A typical FDM printer printing PLA averages 100–200 W (heating spikes are brief); large-format or high-temp printing runs higher, and MSLA resin printers are surprisingly light at 40–80 W. A cheap smart plug with power metering gives you the true figure in one print.

Enter the print duration from your slicer and, optionally, how many similar prints you run per month. You get the cost of this print, the cost per printing hour, and a monthly total. For most people the per-print number is pleasantly small — but if you sell prints, it belongs in your price. Combine it with the filament cost calculator for the full material-plus-power cost of every piece.

Frequently asked questions

How much electricity does a 3D printer actually use?

A consumer FDM printer printing PLA averages roughly 100–200 W, so an 8-hour print uses about 0.8–1.6 kWh — often less than the cost of the filament by an order of magnitude. Resin printers typically use even less.

Where do the country rates come from?

Published average residential rates: EIA (US), the Ofgem price cap (UK), BDEW (Germany), TEPCO standard tariffs (Japan), the AER default offer (Australia), a national average for Canada and the EDF Tarif Bleu (France). They are averages — your bill is the authoritative source.

Should I use the printer’s rated power?

No. The label states the maximum the power supply can deliver. Actual draw averages far below that because heaters cycle on and off. Measure with a power-metering smart plug for an accurate number.

Does the enclosure or a heated chamber change this?

Yes, meaningfully. High-temperature materials (ABS, PC) with a 100 °C bed and a heated chamber can push averages to 300–500 W. Measure one representative print and use that wattage.
