Estimate electricity used by a 3D printer and its accessories. Enter measured average operating watts rather than the peak power supply rating, and include optional idle or standby time.

Calculation results
These are illustrative estimates, not guaranteed costs or fees. All money inputs must be expressed in the chosen denomination. The currency selector does not perform exchange-rate conversion.
Power in kW = watts ÷ 1,000. Energy in kWh = (print watts × print hours + standby watts × standby hours) ÷ 1,000. Multiply kWh by the local tariff for one unit, then by quantity for the full batch.
Worked example
A printer drawing 120 W for 6 hours and 8 W for another 2 hours uses 0.736 kWh. At $0.17/kWh, the estimated energy charge is $0.13 per print, or about $1.25 for 10 prints.
Common questions
Is the printer power supply rating the same as average use?
No. The maximum PSU rating is generally higher than sustained power consumption. For better estimates, measure draw during a representative print.
Should I include heaters and ventilation?
Yes, if their electricity expense belongs to the job. Include enclosure heaters, exhaust systems, or other accessories in average power.
Why are my power bills higher?
This calculator excludes fixed utility charges and equipment unrelated to printing, unless their usage is included in your inputs.
How do I calculate different electricity tariffs?
Change the per-kWh rate to the tariff charged for the operating period. For time-of-use billing, calculate separate periods and add the costs.
