How do you determine utility rates?
The initial rate displayed represents a base residential service (average cost) rate plus 10%. We add 10% to the base rate to accommodate expected surcharges and taxes. If no rate is available, reasonable default values are: Electric $0.15/kWH, Natural Gas: $1.40/Therm ($0.014/ft^3), Fuel Oil: $3.65/gal., Propane $3.00/gal
The actual rates, taxes and surcharges you pay are probably different. We suggest you review a recent utility bill and change the "Assumed Electric (or Gas) Rate" as needed to better match your situation.
Please reference your utility bill or contact your utility for more details on your actual rates.
