Buyers commonly pay for propane tank fills based on the price per gallon and service fees. The main cost drivers are propane price per gallon, cylinder size, and any delivery or service charges.

|---|---|---|---|---|
| Propane (gas) for 4.7 gal capacity | $14 | $20 | $35 | Based on $3-$7/gal; varies with market |

Overview Of Costs
Cost to fill a 20 lb propane tank typically ranges from about $15 to $40 depending on propane price per gallon and any service charges. A typical 4.7-gallon fill at $3-$7 per gallon results in a base range near $14-$33. If a retailer adds a service fee, delivery, or taxes, the total can approach $40. Assumptions: region, current propane price, standard 20 lb cylinder, no leaks or safety issues.

Pricing Variables
Price per gallon fluctuates with crude oil markets and regional supply, while cylinder-specific charges add or subtract a fixed amount per transaction. The flow for a fill includes a visual inspection, valve check, and safe handling, which can introduce small fees. Assumptions: standard 20 lb cylinder, no leaks, in-store fill or curbside service.
Ways To Save
Shop around and plan pickups during off-peak seasons to minimize service charges and taxes. Some retailers offer bulk pricing or membership discounts that reduce the per-gallon rate. Assumptions: non-expedited service, store pickup where available.
Regional Price Differences
Prices can vary by region due to supply, demand, and taxes. In the Midwest, average per-gallon propane might run slightly higher during shoulder seasons, while the Southeast can see lower base prices but higher delivery fees in rural areas. A comparison among three market types shows typical delta ranges of ±10–25% from national averages, influenced by accessibility and local competition.
Labor & Time Considerations
For retail fills, labor is usually minimal or included. When propane is delivered, a technician or driver may charge a small fee for curbside service or inspection. Typical labor-related charges are $0-$10 depending on service type and region. Assumptions: standard fill service, no special handling required.
Additional & Hidden Costs
Hidden costs can include a mandatory refill fee on exchanged cylinders, or a charge for a lost or damaged valve cap. Delivery windows may incur additional charges if a specific time slot is requested. Assumptions: no damaged cylinders, standard exchange policies.
