Estimating Energy Prices

Fuel Type Cost
Electricity
Natural Gas
Heating Oil
Propane
Unknown/Typical

This tool uses national average energy prices as default values. If you don't know what kind of energy you use, you can ignore this option, or select "Unknown/Typical" to use national average price numbers. Use the table below to select prices that most closely match what you pay.

Energy Type Units Low Medium High
Electricity ($/kWh) 0.05- 0.07 0.07-0.11 0.11-0.16
Natural Gas ($/therm) 0.56-0.69 0.69-0.83 0.83-0.90
Heating Oil ($/gal) 1.03-1.19 1.19-1.27 1.27-1.40
Propane ($/lb) 0.10-0.15 0.15-0.21 0.21-0.30

To set energy prices closer to what you actually pay, select Low, Medium, or High based on the ranges shown in the graph at right. For instance, if you pay $0.12 per kilowatt-hour for electricity, you would set the Electricity option on the main Home Energy Checkup screen to "High".

To find out your actual energy prices, take a recent bill and divide the total bill dollar amount by the units of energy used (kilowatt-hours of electricity, therms of natural gas, gallons of oil, or pounds of propane) to get a dollars-per-unit of energy. Select a choice below that is closest to your price for each energy type you use.
