Estimate a bill at Maryland rates
Worked example: 1,000 kWh at Maryland's average rate of 21.41¢/kWh is about $214.10. The state's actual average usage is 1184 kWh/month, which is what produces the $253.42 average bill. These are average effective rates including all charges; your utility's tariff will differ.
