Estimate a bill at Arizona rates
Worked example: 1,000 kWh at Arizona's average rate of 15.38¢/kWh is about $153.80. The state's actual average usage is 1711 kWh/month, which is what produces the $263.16 average bill. These are average effective rates including all charges; your utility's tariff will differ.
