Why your bill can differ

The estimate assumes the entered power draw for every operating hour. Thermostats, inverter controls, room insulation, weather, standing charges, and time-of-use tariffs can change the real bill.

Use the appliance input power, not cooling capacity.
Enter the unit rate from the latest tariff.
Standing charges are not included.
The result is an estimate, not energy advice.
