Live local scenario

Calculate with an editable rate.

Air conditioners cycle or modulate, so scheduled hours alone overstate energy use. The active-runtime input represents average compressor load across the operating window.

Active runtime accounts for cycling. Use 100% for devices that draw the rated power continuously.

Worked calculation

A Australia starting scenario

1.500 kW is multiplied by scheduled time and the 55% active-runtime assumption. The inputs are examples, not claims about every device. Replace each one with the label, meter reading, schedule, and tariff that apply to you.

AC cost = rated kW × scheduled hours × active-runtime share × tariff

Transparent method

The local calculation

AC cost = rated kW × scheduled hours × active-runtime share × tariff

The device model stays global. The currency, tariff scope, validity period, and billing cautions come from the Australia data layer.

Before trusting the result

Three checks for Australia

01

Model daytime solar self-consumption separately from grid imports.

02

Use a realistic inverter duty cycle in mild weather.

03

Keep the daily supply charge outside one appliance’s running cost.
