Estimate a bill at Arizona rates
Worked example: 1,000 kWh at Arizona's average rate of 15.18¢/kWh is about $151.80. The state's actual average usage is 1445 kWh/month, which is what produces the $219.35 average bill. These are average effective rates including all charges; your utility's tariff will differ.
