Estimate a bill at Arizona rates
Worked example: 1,000 kWh at Arizona's average rate of 15.05¢/kWh is about $150.50. The state's actual average usage is 1789 kWh/month, which is what produces the $269.26 average bill. These are average effective rates including all charges; your utility's tariff will differ.
