This is an estimate, not a bill. It multiplies the unit's rated power input by the hours you enter and the tariff shown — it does not model how an air conditioner actually behaves. Real consumption varies with outdoor temperature, how well the room is insulated, the setpoint you choose, how often doors open, and how the unit is serviced. Inverter models (Hoshi and Aki) modulate their output, so in normal use they draw noticeably less than their rated input — treat their figures here as an upper bound.

The default rate is the TNB domestic base tariff of approximately RM 0.44/kWh under the structure effective 1 July 2025. It excludes the AFA fuel adjustment, which changes monthly, and any rebates or incentives. Check your own TNB bill and enter your actual rate for a closer figure.
