buyers typically pay a per-gallon price plus occasional delivery or exchange fees. Main cost drivers include geography, supplier type, cylinder size, and whether a refill or exchange is used. The figures below reflect common U.S. pricing for residential propane refills.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Propane (per gallon) | $2.50 | $3.25 | $4.50 | Volume discounts may apply; seasonal demand affects price |
| Delivery / Refilling Fee | $0.00 | $15.00 | $40.00 | Flat fee or per-gallon surcharge varies by provider |
| Service/Exchange Charge | $0.00 | $10.00 | $25.00 | Exchange often reduces cost per gallon but adds container swap |
| Cylinder or Tank Fees | $0.00 | $0.00 | $20.00 | New cylinder fees or rental may apply |
| Tax | $0.08 | $0.40 | $1.00 | Depends on state and local tax laws |

Overview Of Costs
Typical cost range for a residential propane refill is $2.50 to $4.50 per gallon, depending on location, supplier, and whether a refill or exchange is used. A standard 20-pound cylinder holds about 4.7 gallons, so a full fill can run roughly $12–$23 before delivery fees or taxes. For larger tanks or multiple cylinders, per-gallon costs may drop slightly due to volume, but delivery or service charges can offset those savings.
Costs break down into three primary drivers: the base price of propane per gallon, delivery/refill fees, and any container or administrative charges. Seasonal shifts in demand and regional supply constraints can push prices up during peak heating months or tight supply periods.

What Drives Price
Price components vary by region and service model. Regional market conditions, transportation costs, and supplier pricing strategies shape the per-gallon cost. Residential customers may see different pricing for will-call pickup, home delivery, or exchange programs. Tank size and the efficiency of the compressor or refilling process can also impact the overall amount charged per gallon.
Regional players may offer bundled services (delivery plus refill) or seasonal promotions. If a homeowner uses a local propane retailer that operates with a flat delivery fee, overall cost can swing more due to the fixed charge than the per-gallon price alone.
Ways To Save
Shop around and compare quotes from multiple suppliers to lock in a favorable per-gallon price. Consider scheduling deliveries during off-peak seasons when demand is lower. If feasible, opting for a full refill in a single visit instead of multiple refills can minimize cumulative delivery charges. Some programs offer cylinder exchanges with lower per-gallon rates than refills, though ownership of the cylinder may add upfront costs.
Other cost-saving tactics include buying in larger quantities to leverage volume discounts, signing up for loyalty or price-protection programs, and monitoring price trends to time purchases around favorable market conditions. For customers with long-term propane needs, assessing the total cost of ownership for rented versus owned cylinders can yield meaningful savings.
Regional Price Differences
Prices vary across major U.S. regions due to supply, demand, and distribution infrastructure. In general, households in coastal or densely populated markets may see higher delivery fees, while rural areas often incur higher transportation costs per gallon. A typical regional delta might show:
- West/Central: −5% to +10% relative to national average
- Northeast: +0% to +15% due to higher distribution charges
- South: −5% to +5% on average, with regional promotions
Real-World Pricing Examples
Three scenario snapshots illustrate typical pricing for different needs.
- Basic: 20 gallons, standard refill, no cylinder exchange; delivery fee applies; total around $70–$95 before tax.
- Mid-Range: 40 gallons with exchange service; bulk pricing may reduce per-gallon cost; total around $140–$170 before tax.
- Premium: 100 gallons with multiple tanks, delivery included; higher-volume discounts apply; total around $260–$450 before tax.

Seasonality & Price Trends
Prices tend to rise during peak heating seasons and fall in milder months. COVID-era supply disruptions or refinery constraints can cause short-term volatility. For homeowners budgeting ahead, it’s prudent to monitor regional price quotes in late summer or early autumn when demand starts to climb but before peak winter needs. Early-season promotions from some suppliers can also help flatten costs across the year.
