The cost to fill a 30 lb propane tank varies by region, demand, and service options. This article breaks down typical pricing, common add-ons, and ways to reduce the bill while meeting safety and refueling standards for residential use.
Assumptions: Midwest region, standard 3-5 lb per gallon energy content, standard exchange or refill service, normal access to the tank.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Propane price per gallon | $2.50 | $3.00 | $3.50 | 1 gallon ≈ 4.24 lb |
| Refill to 30 lb capacity | $18 | $25 | $35 | Assumes standard 7.5 gallons in a 30 lb cylinder |
| Delivery or service fee | $0 | $0-$8 | $12 | On-site refills may incur a small fee in some regions |
| Taxes and miscellaneous | $1 | $2 | $4 | State and local charges apply |
Typical Cost To Fill a 30 Lb Tank and What Drives It
Most buyers pay between $20 and $40 to fill a 30 lb propane cylinder, with the average near $25-$30. The main cost driver is the current propane price per gallon, followed by any service or delivery fees and applicable taxes. A full refill equals roughly 7.5 gallons, since one gallon propane weighs about 4.24 pounds. Regional pricing and seasonal demand can shift the total by several dollars.
For a quick estimate, multiply the gallons by the local price per gallon and add any fees. If the service offers a flat refill price, compare it against the per-gallon option to confirm the better value.
Cost Components You Should See in a Quote
Understanding the quote helps prevent surprises. A typical breakdown includes the following:
- Materials: Propane per gallon
- Labor: Not usually charged separately for standard refills, but some mobile services include a small labor/handling fee
- Delivery/On-site service: May apply in some markets
- Taxes: State and local charges
- Permits or inspections: Generally not required for residential refills
Typical price table shows propane price per gallon, refill quantity, and any service fees in one view.
Key Drivers That Change the Final Refill Cost
Two primary variables often swing the total cost:
- Regional propane price per gallon: Coastal areas or peak season often have higher per-gallon rates
- Delivery or service model: In-store pickup versus on-site refill or mobile delivery
Assumptions: standard tank condition, no leaks, standard regulatory compliance, typical demand period.
Strategies to Lower Your 30 Lb Tank Fill Price
Sensible options include choosing in-store pickup when possible, validating per-gallon pricing before committing to a service, and avoiding optional delivery fees by refilling during routine propane runs. Coordinating refills with other outdoor-cooking or heating needs can also reduce the per-fill cost by leveraging bulk or combined service pricing.
Other practical steps: compare multiple vendors in your area, ask about seasonal promotions, and consider a fixed-price refill plan if you expect frequent fills.
Regional Price Variation: What to Expect Across the U.S.
Propane prices vary by region due to supply, distribution costs, and market competition. In the Northeast, prices often trend higher than the Midwest, with the West Coast sometimes charging a premium. Expect a broad range from the low-$20s to mid-$30s for a 30 lb fill, depending on local factors.
Assumptions: average weather impact, typical delivery radius, standard taxes by state.
Practical Quote Example Scenarios
-
Scenario A: In-store pickup, price per gallon $2.80, no delivery fee. Total ≈ 7.5 × $2.80 = $21.00. Tax adds ≈ $1.50. Total ≈ $22.50.
-
Scenario B: Mobile refill service with $8 delivery fee, price per gallon $3.10. Total ≈ 7.5 × $3.10 + $8 = $32.25. Tax ≈ $2.25. Total ≈ $34.50.
-
Scenario C: Large regional supplier offering a fixed $25 refill, delivery included, tax ≈ $2.50. Total ≈ $27.50.
These examples help buyers compare options quickly and validate final quotes against typical ranges.

Note: Always confirm whether a service charge, delivery window, or tank refill etiquette (like valve safety checks) is included in the final price.
