Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Rated electrical input = motor output ÷ efficiency. Average power blends loaded input with the entered unloaded-power percentage. Monthly kWh = average power × scheduled hours × quantity; energy and demand charges are then added.

FAQ
Air Compressor Running Cost Calculator questions
Why include unloaded power?+
Many compressors continue drawing substantial power while unloaded. Enter a measured or manufacturer-specific percentage for a better estimate.
Does motor horsepower equal electrical input?+
No. Horsepower is converted to mechanical output and divided by motor efficiency to estimate electrical input.
Can air leaks be calculated here?+
No. Leaks affect loaded duty and runtime. A leak survey or measured compressor profile provides better inputs for the loaded-time field.
