To determine the Cost per Unit of energy look at a Utility Bill. The price per Unit is the total utility bill divided by the number of units used. For example, if your electric bill is $100 and 800 kWh were used the average price is $100 divided by 800 kWh = $0.1250 per kWh. Likewise if your natural gas bill was $100 and 90 Therms of gas were used the average price is $100 divided by 90 Therms = $1.1100 per Therm.
