Equipment energy consumption calculator

Enter the equipment's nameplate power, the real load factor and the operating schedule. The calculator works out consumption and electricity cost at your tariff.

Real average load, not the nameplate maximum — usually 60–90%

How it is calculated

Average power draw = nameplate power × load factor ÷ 100. Equipment rarely runs continuously at full nameplate power — idle cycles, ramp-up and pauses lower the average.

Monthly consumption (kWh) = average power × hours per day × days per month. Monthly cost = consumption × tariff; yearly cost = monthly cost × 12.

Cost per hour = average power × tariff — a handy figure for costing an operation or comparing the energy efficiency of different equipment.
