Millions of American consumers and businesses make a vital energy choice between propane and natural gas every day, a choice that affects both everyday convenience and long-term expense. Regardless of whether you warm your home, drive appliances, or power your business, knowing regional cost differences between the two fuels can put cash in your pocket and allow you to plan more effectively. As of 2025, changing energy prices, investment in infrastructure, and regulatory policies continue to impact natural gas and propane prices. This comprehensive guide takes into account how each of these fuels is different, what factors influence prices in different U.S. markets, and what choice is best value for your energy requirements.
Before comparing propane and natural gas by region, let’s find out what influences their cost. A range of external and internal drivers influence costs, from production to delivery. Each source of energy has its own cost drivers depending on supply availability, distribution channels, and local demand.
Propane also comes as a byproduct of natural gas and crude oil refining, while natural gas is derived directly from underground reservoirs. Natural gas has been rendered cheaper because of U.S. shale gas surrounding key centers of extraction.
Natural gas is piped, with low delivery costs when an infrastructure is already established. Propane must be transported by truck and stored in tanks, higher costs of delivery, particularly in rural areas.
Propane users must rent or purchase tanks, with additional storage and total cost. Natural gas users are offered central infrastructure by regional public utility firms.
Both gasoline and propane have price spikes in the winter, but the storage level of the propane usually makes for steeper spikes. Propane tends to be more costly in colder regions than natural gas.
When a region does not have either gas plants or refineries, prices for propane go up because of the longer time to ship. Natural gas, which has an extensive network of pipelines, is less exposed to market risk.
Natural gas prices are primarily set by United States production, but propane does have a global export market worldwide. Global demand can influence local propane prices more so than natural gas prices.
Fuel prices can be quite different all over the nation depending on infrastructure, access, and climate. Let’s look at how propane and natural gas prices change per major United States region.
The Northeast is energy-rich because of low temperatures and limited pipeline supplies. Natural gas is still the lower cost at about $1.50–$2.00 per therm, while propane is $3.00–$4.00 a gallon. Propane is used by most non-pipeline accessible homes at a higher cost.
Midwest states enjoy good propane supply chains because they have refineries and also farm application of propane. Propane is between $2.20 and $2.70 per gallon, and natural gas is about $1.30 per therm. Propane is also common in rural communities despite its slightly higher cost.
The South is near natural gas-producing regions. Natural gas is cheap at $1.00–$1.40 per therm, and propane is $2.00–$2.50 per gallon. But mild winters moderate heating needs to the extent that overall annual energy expenses are relatively low for each.
Prices in the West are highest due to larger transportation distances and environmental fees, typically $3.50–$4.20 per gallon. Natural gas is lowest at approximately $1.60 per therm, though California’s high emissions standards add regulatory cost to both alternatives.
In distant, hilly, and rural areas, propane prevails as natural gas pipes are not found commonly. Propane is priced around $2.70–$3.20 per gallon, and natural gas is around $1.50 per them. Although propane is more costly, its availability renders it handier.
Both have expensive energy owing to delivery issues. Alaskan propane is between $3.50 and $4.00 a gallon, and Anchorage natural gas is around $1.80 a therm. Hawaii imports much of its propane, and consequently prices reach up to $5.00 a gallon or more.
Propane contains more energy content, nearly 91,500 BTUs per gallon, versus 100,000 BTUs per therm of natural gas. Propane thus burns more intensely and with greater heat output per unit, roughly offsetting its per-unit cost.
Natural gas has the advantage in urban and suburban segments where pipeline facilities exist but propane is the choice in rural segments without the pipes.
Propane to natural gas or natural gas to propane needs new equipment or conversion. The cost of this type of conversion fees is $1,000–$3,000 depending on system size and appliance model.
Both of them are cleaner than coal or oil but less CO₂ per BTU is produced by natural gas. But propane lacks methane, an extremely potent greenhouse gas, so it is the green one if leakage of methane is not a concern.
Propane consumers have greater control over their fuel supply. Households can arrange deliveries as long as they are equipped with a propane tank, and they are not tied to the public utilities.
Natural gas prices are steadier due to longer contracts and enormous infrastructure. Propane prices are less stable due to export demand and storage constraints.
With clean, efficient energy becoming an increasing priority, natural gas and propane will continue to be dominant forces in the American home. Domestic investment in renewable natural gas (RNG) and renewable propane (bio-propane) is changing industry trends. Homeowners will be able to look forward to cleaner, more consistent energy sources in the coming decade, although cost will change as infrastructure grows.
It’s time to balance propane against natural gas, short-term expense against long-term considerations. If your house is connected to a natural gas pipeline, the cheaper unit price does make it the deal. But for rural homes or homes outside the reach of a gas pipeline, the portability, ease, and efficiency of propane make it a top-notch and handy choice. Your location, energy needs, and personal needs dictate the best option.
Knowledge of propane versus natural gas price volatility by region throughout the United States makes you an economic, enlightened decision-maker. Natural gas dominates on price in the city, but propane delivers certainty and control in rural settings. In 2025 and beyond, the most educated energy shoppers are those who exceed national averages and pay attention to neighborhood facts. Whatever you’re warming up with propane in Montana or natural gas in Texas, knowing how your community impacts your bill guarantees comfort, efficiency, and savings all year round.
