Prices to fill a propane tank vary by tank size and region, with key cost drivers including propane wholesale prices, delivery, and taxes. This guide provides practical, USD-based estimates and clear ranges to help buyers budget accurately for propane filling services.

Assumptions: small grill tanks are filled by weight or gallon equivalent; larger residential tanks are priced per gallon with delivery included where applicable.

Item	Low	Average	High	Notes
Propane (per gallon, residential retail)	$2.50	$3.00	$3.75	Prices vary by region and supplier
20-lb grill cylinder fill	$10	$18	$35	Equivalent to ~4.7 gallons
Delivery/Service fee	$0	$15	$40	Often included in larger fills
Taxes/Fees	$0	$3	$30	State and local charges may apply

Overview Of Costs

Typical cost range for residential propane fills depends on tank size and demand. For small grill cylinders, expect roughly $12-$35 per fill; for home heating or large bulk tanks, per-gallon pricing determines total costs, commonly $2.50-$3.75 per gallon. This section provides total project ranges and per-unit ranges with assumptions noted.

Cost Breakdown

Component	Low	Average	High	Notes
Propane	$2.50/gal	$3.00/gal	$3.75/gal	Gallon-based pricing; ranges by market
Delivery/Service	$0	$15	$40	One-time delivery fee or included in larger fills
Taxes	$0	$3	$30	Sales tax or environmental fees
Other Fees	$0	$2	$8	Environmental or disposal charges where applicable
Contingency	$0	$2	$6	Small buffer for price fluctuations

Pricing Variables

Key drivers include tank size, regional propane prices, and delivery logistics. The following variables shape final costs: tank capacity in gallons or pounds, whether the fill is at a retailer or via a delivery service, and seasonal demand.

What Drives Price

Regional price differences reflect local supply, taxes, and competition. A typical upstate vs. coastal delta can reach several percent. Tank size and fill method (on-site vs. delivered) also shift costs.

Seasonality & demand propane prices tend to rise in cold months when heating needs are higher, and may dip during milder seasons. Delivery windows and accessibility can add or reduce charges.

Ways To Save

Shop around for local suppliers offering price transparency and volume discounts. Consider scheduling deliveries ahead of peak demand and consolidating fills to reduce per-delivery fees.

Regional Price Differences

Regional Snapshot compares three U.S. regions to illustrate price spread.

• Northeast urban: +5% to +12% versus national median due to logistics and taxes.
• Midwest rural: −2% to +6% reflecting lower distribution costs but variable supplier competition.
• South suburban: near national average with modest delivery fees depending on proximity.

Labor & Installation Time

Residential propane fills are typically a quick service, not a full installation job. Labor hours are minimal, often less than 0.5 hours per fill, with crew costs embedded in delivery charges where applicable.

Additional & Hidden Costs

Hidden costs can include after-hours delivery surcharges, redelivery fees, or mandatory cylinder exchange programs. Always verify if a price quote includes all charges or if taxes and disposal fees will be added at the time of service.

Cost Compared To Alternatives

Alternatives to consider include using a smaller, refillable cylinder as a backup, or switching to an on-site propane tank with automatic refills if your home uses propane heavily. Per-gallon costs tend to be similar, but delivery schedules and tank rental fees can differ.
