Prices for refilling propane depend on tank size, local delivery, and whether you buy propane by the gallon or opt for an exchange. This guide highlights typical costs in the United States and the main factors that influence the final bill.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Propane per gallon | $2.50 | $3.00 | $3.50 | Gas station or supplier price before any fees |
| 20-lb cylinder refill | $18 | $25 | $30 | Assumes standard home grill/BBQ size; a typical fill |
| Delivery/fees | $0 | $20 | $60 | Urban delivery may be higher |
| Tank exchange price | $24 | $32 | $40 | New or refurbished cylinder swap |
| Total project cost | $60 | $85 | $100 | Assumes one 20-lb refill or exchange |
Assumptions: region, tank size, delivery service, and whether refills are purchased by the gallon or via exchange.
Overview Of Costs
Typical cost range for a propane refill depends on tank size and whether a refill is done on-site or via exchange. In most households, a standard 20-lb cylinder refill runs in the mid-20s, while price per gallon is commonly around the low to mid $3 range. A separate delivery charge or a tank exchange adds to the total. Budget awareness is important when scheduling refills during peak demand or in high-cost regions.
Cost Breakdown
Table shows where money goes when refilling or exchanging propane.
| Category | Typical Range | What’s Included | Notes |
|---|---|---|---|
| Propane | $2.50–$3.50 per gallon | Propane fuel for use | Prices fluctuate with crude oil markets and supply |
| Tank size/quantity | 4.7 gallons (20-lb cylinder) | Propane in cylinder plus empty weight | Common for grills; larger tanks cost more per fill |
| Delivery or pickup | $0–$60 | Delivery service or pickup fee | Urban areas often higher; some promos waive fee |
| Container option | $24–$40 (exchange) | New or swapped cylinder | Exchange may include a safety inspection |
| Taxes & permits | $0–$5 | Sales tax where applicable | Not all regions apply tax at point of sale |
What Drives Price
Pricing is influenced by several factors, starting with regional supply and demand. Propane is often cheaper in mild-to-moderate climates when heating demand is low, and more expensive near peak grilling season or in rural areas with limited suppliers. Tank size and weight affect transport costs, while exchange programs may include inspection and cylinder credits. Another driver is the form of purchase: pay-as-you-go by the gallon versus a fixed exchange price can shift the overall cost.
Pricing Variables
Two niche-specific drivers affect propane refill costs:
- <bTank size and capacity — a 20-lb cylinder holds about 4.7 gallons; larger tanks or multiple tanks increase total cost and may require separate delivery windows.
- <bDelivery model — some providers offer free delivery with a minimum purchase, while others charge a flat fee or tiered rates that rise in dense urban zones.
Regional Price Differences
Prices vary across regions, with notable deltas among Urban, Suburban, and Rural markets. In a typical year, Urban centers may see higher delivery fees and convenience premiums, Suburban markets balance delivery and access, and Rural areas might incur longer travel times and higher per-gallon rates. Expect ±10–25% variations between regions for both propane price per gallon and delivery fees.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes, with assumptions noted below. Assumptions: region, specs, labor hours.
Basic
Scenario: One 20-lb cylinder, on-site refill, no delivery fee included in price estimation.
- Propane: $2.50–$3.00 per gallon
- Refill amount: 4.7 gallons
- Estimated total: $12–$18
Mid-Range
Scenario: Cylinder exchange with delivery, standard home grill use, regional average pricing.
- Exchange price: $28–$34
- Delivery fee: $12–$25
- Estimated total: $40–$60
Premium
Scenario: Multiple refills or exchanges in a busy season, delivery in an urban market, larger household needs.
- Propane per gallon: $3.25–$3.75
- Total gallons: 9–12 across two fills
- Delivery/fees: $20–$60
- Estimated total: $100–$140
Cost Compared To Alternatives
Alternatives and price comparisons help buyers decide between refills and exchanges. Refilling a cylinder typically costs less per fill when buying by the gallon, but exchanges offer convenience and safety checks. For frequent use, a larger plan or bulk propane supplier may reduce per-unit costs, while seasonal demand spikes can push prices higher.
Maintenance & Ownership Costs
Over time, owning a tank rather than leasing or swapping can alter long-term costs. Routine inspection and certification of cylinders (as required) add minor recurring expenses that may be included in some services. For households using propane year-round, calculating a yearly average through a simple projection helps compare with alternative energy sources.
Seasonality & Price Trends
Propane prices tend to rise ahead of grilling season and during periods of peak heating demand in cooler months. Off-peak pricing can offer savings, especially for customers with flexible refill timing. Planning ahead for scheduled refills can reduce surprise charges and simplify budgeting.
Permits, Codes & Rebates
Local rules rarely impose permits for standard cylinder refills, but some jurisdictions tax propane purchases or offer rebates for energy-efficient grills or outdoor cooking setups. Check regional tax rules and potential rebates that apply to outdoor appliances and energy use.
