Estimate a bill at Indiana rates
Worked example: 1,000 kWh at Indiana's average rate of 17.02¢/kWh is about $170.20. The state's actual average usage is 1110 kWh/month, which is what produces the $188.99 average bill. These are average effective rates including all charges; your utility's tariff will differ.
