Overview Of Costs
LP tank refill costs vary by tank size and propane price; typical ranges cover small grill tanks to larger consumer tanks. For a 20-lb cylinder, expect roughly $11–$28 depending on market price and whether you choose refill or exchange. Larger tanks cost more, with 30–100 lb cylinders ranging from about $18–$40 per refill, before any delivery fees.
Assumptions: region, tank size, supplier type, and current propane market.
Cost Breakdown
Understanding the components helps identify savings opportunities and hidden charges. A typical refill includes the propane volume, any per-gallon price, and possible service or delivery fees. The total may also reflect taxes and safety checks if required by a local code or supplier policy.
| Component | Typical Range | Unit | Notes |
|---|---|---|---|
| Propane Volume | 4.0–8.0 | gallons | Corresponds to 20–30 lb tanks; larger tanks hold more gallons. |
| Propane Price | $2.50–$3.50 | /gallon | Market price fluctuates weekly; regional differences apply. |
| Delivery / Service Fee | $0–$25 | fee | Free delivery with minimum refill in some regions. |
| Refill vs Exchange Premium | $0–$13 | per tank | Exchanges often have higher upfront cost; inconvenience factor varies. |
| Taxes / Permits | $0–$5 | flat or % | State or local taxes; typically minor for gasoline products. |
What Drives Price
Propane market conditions primarily drive refill costs, with tank size and location adding variation. The lower end reflects small tanks during stable market periods; the higher end appears when delivery fees apply or during peak demand seasons like winter. Regional pricing and supplier competition can shift the price by a noticeable margin.
Assumptions: market price, regional supplier policies, and delivery choices.
Ways To Save
Consider timing, tank size, and delivery options to reduce costs. Opting for a local refill rather than an out-of-town supplier can cut delivery fees. If practical, refill or exchange based on a predictable schedule; buying in larger tanks or consolidating refills can yield lower per-gallon costs over time.
Assumptions: usage frequency, access to nearby suppliers, and willingness to consolidate refills.
Regional Price Differences
Prices vary across regions due to logistics, availability, and competition. In the Northeast, refills may include a modest delivery fee, while the South may feature lower delivery charges. Midwest markets often see competitive per-gallon pricing but higher exchange premiums. Expect a ±15%–25% delta between regions for identical tank sizes and services.
Assumptions: three representative regions; standard 20-lb tank refills.
