Propane or Natural Gas Cheaper? Which is More Cost-Effective?

When it comes to choosing between propane and natural gas for your residential or commercial needs, cost is often a crucial factor to consider. Both propane and natural gas are widely used for heating, cooking, and powering various appliances. In this article, we will delve into the cost comparison of these two popular energy sources to help you make an informed decision based on your specific requirements. Let's explore the factors that influence their pricing and which option might be more cost-effective for you.

Supply and Demand Dynamics

The cost of both propane and natural gas is subject to the principles of supply and demand. Natural gas is generally more abundant and widely available, mainly due to its extraction from natural gas wells and reservoirs. On the other hand, propane is a byproduct of natural gas processing and crude oil refining. As such, its supply can be influenced by factors affecting the production of these primary resources.

When demand for natural gas increases, its price may escalate due to limited supply, especially during peak usage seasons like winter. Propane, being a derivative of natural gas, is also affected by these fluctuations in demand, but its price can be more volatile since it is transported and stored separately.

Distribution Infrastructure

One of the primary cost factors is the distribution infrastructure required for each energy source. Natural gas has an extensive pipeline network, making its transportation more efficient and cost-effective. As a result, areas with well-established natural gas infrastructure tend to have lower gas prices.

Propane, however, is typically stored in tanks and delivered via trucks to individual locations. This transportation process adds to the overall cost of propane, especially in remote or less populated areas that lack a developed propane delivery infrastructure.

Energy Efficiency

The energy efficiency of both propane and natural gas also plays a significant role in determining their overall cost-effectiveness. Propane contains more energy per unit volume than natural gas, meaning it can produce more heat when burned. As a result, propane-powered appliances may require less fuel to achieve the same level of heating or cooking as their natural gas counterparts.

This higher energy density can make propane more cost-effective in certain applications, particularly in areas where natural gas prices are higher or during periods of peak natural gas demand.

Conversion Costs

If you are considering switching from one energy source to another, conversion costs should also be factored into your decision. Converting appliances or infrastructure to accommodate a different fuel type can be expensive, potentially outweighing any potential savings from the switch.

In some cases, existing infrastructure might favor one energy source over the other, making the conversion financially unviable. Therefore, it's essential to evaluate the conversion costs and potential savings over the long term before making a decision.


In general, natural gas is cheaper than propane when it comes to heating. This is because natural gas is typically more abundant and easier to extract. Propane prices are historically higher than natural gas. However, because propane has higher BTUs than natural gas, less fuel is consumed when heating. So although propane costs more than natural gas, it can be cheaper if less energy is used.

Consumer-grade propane costs approximately 2-3 per gallon. The average natural gas cost per therm is $0.95 or $9.52 per thousand cubic feet.

The choice of the more cost-effective option largely depends on various factors, including your location, existing infrastructure, energy requirements, and fluctuations in supply and demand. Natural gas often proves to be the cheaper option in areas with a well-established pipeline network, whereas propane can be more cost-effective in regions with limited natural gas availability.

Before making a decision, it's crucial to conduct a thorough cost analysis, taking into account the specific factors affecting propane and natural gas prices in your area. Consider consulting with energy experts or local suppliers to get the most accurate and up-to-date pricing information. By making an informed choice, you can ensure that your energy needs are met efficiently and cost-effectively for years to come.
