Calculate the cost of heating your home with Gas, Oil, Propane & Electricity
Get heating costs estimate in your state, for Oil, Natural Gas, Propane, and Electricity, using a Hot Air Furnace, Boiler (standard & condensing), Air Source & Geothermal Heat Pump.
NOTE: Our calculator provides the most updated local energy costs in your state, which are pre populated in the price fields. However, your actual cost may be different, depending on your supplier.
March 2022 Heating Costs Update: Due to unprecedented recent increase in cost of all heating fuel types, average cost of Natural Gas has increased by $as much as $0.50 per Therm, Heating Oil & Propane has gone up by $0.6-$0.90/gallon, cost of electricity has gone up by $0.01-$0.05 per kWh. On average, this represents between 10-25% increase in total heating costs.

RESULTS: You will get a full season (6 months, from mid-October through mid-April) cost of heating your home, cheapest fuel for your heating system type, as well as estimated prices for replacing / installing a new heating system.
To get an accurate cost estimate, set your house square footage, adjust local prices for Oil, Natural Gas, Propane, and Electricity, choose your heating equipment type, home insulation grade & efficiency rating of your heating system.
¹ Resutls for electric stip (baseboard) heating are calculator based on your home's Heat Load, excluding any flue gas, duct & radiator loses, which are present in hydronic and forced air heating systems (boilers, furncaes, Geothermal Heat Pumps), since nominal effciecny of electric resistance heating is 100%, and is calculated at 3412 BTUs / 1 kW.
² Results for Heat Pump presume a 2.9 COP Ductless Heat Pump system, which is typical for multi-zone Hyper Heat systems from Fujitsu, Mitsubishi, Daikin, LG, and other top tier manufacturers, and is calculated at 9895 BTUS / 1 kW.
What is COP? COP or Coeffcienct of Performance is a fancy accronym for a multiplier of efficiency of a HEAT PUMP system VS Resistive Electric Baseboard heating.
Example: Resitive Electric Heater produces 3412 BTUs of Heat for 1 kW (1000 Watts) of power useage. A heating system with 3.0 COP will provide 3 times the heat output for each 1 kW of electricity that it uses. In our case 3412 * 3 = 10236 BTUs per 1 kW.
Bottom line - a 3 COP heat pump is 3 times as efficient as Electric Baseboards or a space heater!
Here is how much different residential Heating Fuels Cost in your state (South Carolina) as well as US Average. Breakdown of Heating Energy Costs, by fuel type: Natural Gas, #2 Fuel Oil (heating oil), Propane, and Electricity.
|US Avg:||$2.37 / Therm||$5.40 / Gal||$2.67 / Gal||$0.163 / kWh|
|South Carolina:||$2.55 / Therm||$4.94 / Gal||$5.32 / Gal||$0.151 / kWh|
Learn hot to get "Almost Free" heating and cooling when you combine High Efficency Ductless Heat Pumps (with -15°F Low Temp Heating) and large enough Solar PV array, which is financed with fixed rate loan - your energy savings will in most cases be higher than the loan payment!
Prices above are as follows:
Natural Gas - $/Therm
Heating Oil and Propane - $/Gallon
Electricity - $/kWh.

* We use a Geolocation to identify your state. However, it's not always accurate. Therefore, you may need to adjust your local prices to correct values (see table at the bottom).
Additionally, prices provided for your state are AVERAGE for your whole state, and may differ greatly from one part of the state to another. We inlcude local prices for your convenience. However, for accuracy purposes, it is ideal for end user to correct these prices to what local suppliers actually charge!

How to use Heating Fuel Cost Calculator
US Energy Costs table by State:
Here is the price table of Heating Fuels such as Natural Gas, Fuel Oil, Propane and Electricity, for each state, including Washington DC, AL and HI, as well as US average.
Natural Gas prices are in THERMS, which is an equivalent of about 100,000 BTUs, but can easily be converted to 100/1000 Cu. Ft. See how to do it below the price table.
NOTE for MA Residents: We have adjusted Massachusetts electric rate from $0.246 to $0.305 / kWh (20% increase), which went into effect on Jan 1, 2022, per Eversource rates page.
|Gas||#2 Fuel Oil||Propane||Electricity|
|District of Columbia||$2.81/therm||$5.73/gal||$6.11/gal||$0.139/kWh|
** NOTE: If your gas company charges you in units other than therms here are local SC and US average costs for natural gas in other common delevery units:
COMMON Gas measurement units:
CCF = 100 Cubic Ft.
MCF = 1000 Cubic Ft.
Price per CCF (in SC): $2.64
Price per MCF (in SC): $26.42
Price per CCF (US Average): $2.64
Price per MCF (US Average): $26.42
One therm is almost the same as 1 CCF. However, "almost the same" is the key here!
The heat content of Therm is 99976 BTUs, while 1 CCF has 103675.112 BTUs, and 1 MCF has 1036751.12 BTUs.
Why Are THERMS, CCF & MCF Important?
Our Heating Cost Calculator uses THERMS to estimate the cost of heating with natural gas. However, since every gas company uses their own units of calculating your cost of gas, it is important that you provide the correct unit cost, to get an accurate estimate.
Basically, there are approximately 3.7% more BTUs in 1 CCF vs 1 Therm, which means that you will need 3.7% fewer CCFs to produce same heat as if you calculated in therms.
- If your gas company is charging you CCF you should divide your Cost/CCF by 1.037, and adjust the GAS Price divide your in the calculator.
- If your gas company is charging you MCF you should divide your Cost/MCF by 10.37, and adjust the GAS Price divide your in the calculator.
- If you currently do not use Natural Gas, then you don’t need to do anything.
