Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Effective hours = scheduled hours × duty cycle. Monthly energy = input kW × effective hours. Monthly cost = energy × electricity price + maintenance allowance.
FAQ
Air Conditioner Running Cost Calculator questions
What is duty cycle?+
It is the share of scheduled time that the compressor operates at the entered input power.
Do inverter air conditioners use constant power?+
No. Variable-speed systems modulate, so average input can differ substantially from rated input.
Why can actual bills differ?+
Weather, thermostat settings, occupancy, insulation and rate structures all change energy use and cost.
