FUEL COST COMPARATOR Natural Gas vs. Oil

LOAN PAY BACK CALCULATOR

Need to finance your new equipment? Use the loan calculator below to determine your new monthly costs.

With your monthly savings of: $

And a monthly loan fee of: $

You will save approximately $ each month on your energy bill until your loan is paid off.

(A negative value indicates an additional amount over and above the “Projected monthly cost of oil for the term of the loan.”)

* For purposes of this calculation, you can assume that the "Average price per gallon" of oil is the price from your most recent oil bill.

** The natural gas equivalent price of oil for Connecticut Natural Gas is calculated using the average price per ccf of natural gas for a typical CNG home from November 1, 2015 through October 31, 2016 and multiplying it by a heat content adjustment factor of 1.4. All transportation and delivery charges are reflected in this price. It is based on a typical home using 1,000 ccf annually and on a Residential Heating System Expansion Off-Main rate.

Using the "Current Market Price per Gallon" of oil for this calculation of projected savings does not imply that the current market price for either fuel will be the market price going forward. The market prices of oil and natural gas in the future months may be the same as, higher or lower than the current prices for each commodity.

Please note that this calculator is provided for reference purposes only. Energy savings are estimated and actual results may vary.

This calculation assumes that you are replacing your existing furnace or boiler with a new unit of the same efficiency. Most new furnaces and boilers are more efficient than the older models they replace resulting in greater savings.

FUEL COST COMPARISON Natural Gas vs. Propane

(A negative value indicates an additional amount over and above the “Projected monthly cost of propane for the term of the loan.”)

* For purposes of this calculation, you can assume that the "Average price per gallon" of propane is the price from your most recent propane bill.

** The natural gas equivalent price of propane for Connecticut Natural Gas is calculated using the average price per ccf of natural gas for a typical CNG home from November 1, 2015 through October 31, 2016 and multiplying it by a heat content adjustment factor of .91. All transportation and delivery charges are reflected in this price. It is based on a typical home using 1,000 ccf annually and on a Residential Heating System Expansion Off-Main rate.

Using the "Current Market Price per Gallon" of propane for this calculation of projected savings does not imply that the current market price for either fuel will be the market price going forward. The market prices of propane and natural gas in the future months may be the same as, higher or lower than the current prices for each commodity.
