When filling a 30 lb propane tank, buyers typically see a modest cost driven by current propane prices, regional taxes, and outlet margins. This guide outlines typical cost ranges, per-gallon pricing, and factors that can push the total above or below expectations. The aim is to provide a clear, practical estimate for U.S. buyers seeking a quick price reference.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Tank fill volume | 7.0 gal | 7.5 gal | 7.9 gal | Based on 30 lb tank capacity |
| Propane price per gallon | $2.50 | $3.00 | $3.75 | Variations by region and season |
| Estimated fill cost | $18.75 | $22.50 | $29.63 | Volume × per-gallon price |
| Taxes/fees | $0.50 | $1.00 | $2.00 | Local/state surcharges may apply |
| Total range | $19.25 | $23.50 | $31.63 | Low–high estimates |
Overview Of Costs
Typical cost range for a 30 lb propane tank fill is roughly $20–$32, with most customers paying around $22–$25 in many regions during non-peak seasons. Prices fluctuate with wholesale propane markets and local service charges, so the price can spike during winter or high-demand periods. Per-unit pricing estimates help buyers compare options between suppliers and stations.
Assumptions: region, tank condition, fill station policies, and current propane spot prices.

What Drives Price
Propane price per gallon is the primary driver, typically ranging from $2.50 to $3.75 depending on region and season. Tank size and fill accuracy also influence cost indirectly: official fills ensure near-rated volume, while underfilling or overfilling can affect total price. Regional taxes and station-specific margins add variability to the final bill.
Other notable factors include supply disruptions, occasional promotional pricing, and whether the refill includes safety checks or exchange credits.

Ways To Save
Shop around local gas stations, hardware stores, and propane suppliers to compare per-gallon prices and fill policies. Buying during off-peak seasons, taking advantage of loyalty discounts, or using bulk or multi-tank pricing may reduce the overall cost. Some outlets offer price caps during extreme weather or provide free safety inspections as part of a fill.
Assumptions: single 30 lb tank fill, no exchange discount.
Regional Price Differences
Regional variation can swing costs by roughly ±15–25%. For example, urban areas near large distribution hubs may show higher margins, suburban markets often align with regional averages, and rural stations might advertise lower posted prices to attract customers. Seasonal demand and transportation costs contribute to these differences.
Real-World Pricing Examples
Sample scenarios below illustrate typical outcomes across common outlets.
- Basic — 7.5 gallons, no promotions; region with mid-range price: 7.5 × $3.00 + $1.00 tax ≈ $23.50.
- Mid-Range — same volume, regional promo; price ≈ $25–$28 including small fee.
- Premium — high-demand season or premium service station; price ≈ $30–$32 total.
Assumptions: US region, standard 30 lb tank, current market pricing.
