Buyers typically pay for propane by the gallon, plus a fill-and-service fee in some cases. For a standard 20‑lb tank, the total cost depends on current fuel prices, the tank’s fill level, and any local service charges. This guide presents practical pricing ranges in USD with clear low–average–high estimates to help budgeting before a refill.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Propane price | $2.40 | $3.00 | $3.80 | Prices per gallon; 20‑lb tank holds about 4.8 gallons |
| Gallons needed (approx) | 4.3 gal | 4.8 gal | 5.2 gal | Based on 80% fill rule and weight target |
| Estimated fill cost | $10.40 | $14.40 | $19.76 | 4.3–5.2 gal × price per gallon |
| Service or dispensing fee | $0 | $2.00 | $5.00 | Some shops charge for handling |
| Tax | $0 | $1.50 | $3.00 | State/local sales tax may apply |
| Total estimate | $12.40 | $17.90 | $28.76 | Includes pump price, fees, and tax |
Assumptions: region, specs, labor hours.
Overview Of Costs
Typical cost range for refilling a 20‑lb propane tank is about $14–$18 before tax in many U.S. markets. Actual totals can shift with local propane prices, seasonality, and any service charges. A few markets report higher costs during peak demand months or when demand for cylinders rises. Understanding the per‑gallon rate and the approximate gallon content helps set realistic expectations.
Cost Breakdown
| Component | Low | Average | High | Notes |

| Materials | $2.40/gal × 4.3 gal | $3.00/gal × 4.8 gal | $3.80/gal × 5.2 gal | Propane price per gallon varies by region |
| Labor | $0 | $0–$2 | $0–$5 | Self-serve vs. counter fill |
| Permits | $0 | $0 | $0 | Typically not required for refills |
| Taxes | $0 | $1.50 | $3.00 | State/local levy varies |
| Delivery/Disposal | $0 | $0–$1 | $0–$2 | Usually only for bulk purchases |

Factors That Affect Price
Regional price differences are common, with urban centers often showing higher per‑gallon rates than rural areas. Weather and seasonal demand can push prices up during winter heating seasons or major outdoor cookout weekends. Tank size and fill method influence the total as well; some shops fill to 80% to preserve safety margins, which affects the final weight and cost.
Ways To Save
Shop around and compare nearby suppliers to lock in the best per‑gallon price. Consider refilling at a warehouse or club that accepts propane cylinders, which may offer lower dispensing fees. If you’re flexible, refilling during off‑peak times can yield small savings, especially in markets with variable demand. Some retailers offer loyalty discounts or bundled maintenance that reduce overall costs over time.
Regional Price Differences
Three markets illustrate variation: coastal metro areas often run $3.20–$3.80 per gallon, suburban regions typically see $2.90–$3.40, and rural markets can drop to $2.60–$3.10. For a 4.8‑gal fill, this translates to roughly $12–$16 in rural areas, $14–$18 in suburbs, and $16–$20 in some cities before tax and fees.
Real-World Pricing Examples
Basic — 4.3 gallons at $2.50/gal, no extra fees; total ≈ $10.75. Assumptions: region, 80% fill, no tax.
Mid-Range — 4.8 gallons at $3.10/gal plus $2 dispensing fee; total ≈ $17.48. Assumptions: standard tax applied.
Premium — 5.2 gallons at $3.60/gal with $5 service fee and $1.50 tax; total ≈ $22.60. Assumptions: peak demand and added handling.
What Drives Price
Price drivers include per‑gallon propane cost, regional taxes, fill level target, and any service fees. The main variable is current propane market pricing, which can shift monthly based on supply, demand, and wholesale costs. Consumers should estimate on a per‑gallon basis and apply an appropriate safety margin for taxes and potential fees.
Cost Compared To Alternatives
Refilling versus replacing a 20‑lb tank is generally cheaper than buying a new cylinder. If a tank is old or shows corrosion, some shops recommend replacement rather than refill, which increases upfront cost but may improve safety. For frequent grill users, maintaining a steady supply via refill can deliver predictable, incremental costs rather than infrequent high outlays.
