Propane tank refills vary by gas price, tank size, and service options. Buyers typically see a mix of liquid propane price per gallon, refilling fees, and possible delivery charges. The cost to refill a standard 20-lb cylinder generally falls in the $12-$25 range, with larger cylinders or off-peak demand pushing higher.
Assumptions: region, tank size, fill method (refill vs exchange), labor hours where applicable.

Overview Of Costs
Basic pricing combines gas price per gallon, a refill or delivery fee, and taxes. For a standard 20-lb cylinder, most households pay in the $12-$25 range for gas itself, with total out-the-door costs commonly $18-$35 after fees in many markets. Larger cylinders (per-gallon costs scale similarly) push total refills higher, while exchanges can be higher or lower depending on the program. Regional market conditions and seasonal demand drive notable price differences.
Cost Breakdown
The breakdown below reflects typical components of a propane refill transaction for a consumer in the United States. Assumptions include standard 20-lb cylinders, local tax, and common delivery practices.
Components That Typically Matter
- Propane Gas (per gallon equivalent)
- Refill Fees or Service Charges
- Delivery or Trip Fees
- Taxes
- Option to Exchange Cylinder (vs Refill)
Gas price per gallon can swing with wholesale markets and seasons, and some retailers price by the cylinder rather than by the gallon, which can alter the effective unit cost. Expect small differences between urban, suburban, and rural delivery options.
What Drives Price
Key price drivers include the current propane wholesale price, cylinder size, and the service model (refill vs exchange). Seasonal demand, fuel distribution costs, and cylinder maintenance requirements also influence price.
Regional Price Differences
Prices vary by region due to transportation costs and local taxes. In the Northeast, prices tend to be higher than in the Midwest, with Southern markets often closer to the national average. For a 20-lb cylinder, regional spreads may range ±15-30% from a national baseline.
Labor, Hours & Rates
Propane refilling is generally a gas service with minimal direct labor costs passed to the consumer, aside from delivery. Where delivery is included, per-visit charges may appear; in DIY scenarios, labor is not a factor.
Extras & Add-Ons
Some providers add fees for emergency delivery, out-of-area service, or cylinder testing and inspection fees. Hidden costs can appear as minimum-order charges or environmental disposal fees.

Budget Tips
- Coordinate refills to align with low-demand pricing windows if possible.
- Choose refills over exchanges if the price delta is modest.
