1. What is the Electricity Bill Tariff Calculator?

The Electricity Bill Tariff Calculator estimates your electricity costs based on usage, tariff rates, and fixed charges as regulated by the Australian Energy Regulator (AER). It supports both time-of-use and flat tariff calculations for Australian households and businesses.

\[ Bill = Usage (kWh) \times Tariff Rate + Fixed Charges (AER regulated) \]
