Estimate a bill at Mississippi rates
Worked example: 1,000 kWh at Mississippi's average rate of 14.43¢/kWh is about $144.30. The state's actual average usage is 1655 kWh/month, which is what produces the $238.78 average bill. These are average effective rates including all charges; your utility's tariff will differ.
