The propane tank Walmart price depends on whether the buyer wants a new cylinder, an exchange, or a refill. A new 20-pound grill tank commonly costs about $45-$80 before propane, while an exchange is often $19-$25 and a refill is roughly $15-$25; location, tank features, and retailer availability affect the final bill.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New empty 20-lb tank | $45 | $60 | $80 | Purchase price; propane not included |
| New filled 20-lb tank | $55 | $75 | $100 | Availability and fill quantity vary |
| 20-lb tank exchange | $19 | $22 | $25 | Usually requires an eligible empty cylinder |
| 20-lb tank refill | $15 | $20 | $25 | Often priced by gallons dispensed |
| Small 1-lb cylinder | $4 | $6 | $9 | Single-cylinder price; multipacks vary |
What a 20-pound Walmart propane tank usually costs
For a standard barbecue grill, a buyer will typically spend $45-$80 for a new, empty 20-pound cylinder, or about $55-$100 for a cylinder sold with propane. The average purchase price for a new tank is near $60 before fuel. Walmart prices and stock vary by store and online listing, so the checkout total may differ by model, seller, shipping, and local inventory.
A standard 20-pound cylinder holds about 4.7 gallons when filled to the safe fill limit. A listing described as “20 lb” refers to the approximate propane capacity, not the tank’s empty weight. New cylinders may include an overfill prevention device and a protective collar; compare the listing details rather than assuming every tank has identical fittings or included fuel.
For a first-time buyer, budget about $60-$80 for a new empty grill cylinder and add the local cost of filling it. A filled option can be convenient, but it is not always the cheapest way to obtain propane. Check whether the product is sold by Walmart or a marketplace seller, whether delivery is offered, and whether the listed price includes fuel.
Assumptions: standard 20-pound grill cylinder, ordinary access, and typical U.S. retail pricing; local Walmart inventory and promotions can change these ranges.
How tank hardware, propane, and labor shape the quote
Most household grill-cylinder purchases do not require installation labor. The cost is mainly the cylinder itself and, if purchased filled, its propane. For a built-in grill, a larger stationary tank, or a complicated fuel-line installation, the costs below do not apply; those projects need equipment, permits, and professional work.
| Quote component | Typical price | What it covers | When it applies |
|---|---|---|---|
| Empty 20-lb cylinder | $45-$80 per tank | Tank, valve, collar, and base | Buying a new grill tank |
| Propane fill | $3-$5 per gallon | Fuel dispensed, often with a minimum charge | Filling a refillable cylinder |
| Exchange cylinder | $19-$25 per exchange | Replacement cylinder with propane | Trading an eligible empty tank |
| Regulator or hose | $15-$45 | Grill connection parts | Replacing worn or incompatible parts |
| Delivery or handling | $0-$30 | Shipping or local handling, if offered | Online or delivered orders |
Filling charges are often based on the amount dispensed, but station pricing and minimum fees differ. At $3-$5 per gallon, a nearly empty standard cylinder that receives about 4.7 gallons would cost approximately $14-$24 for fuel, before any separate service charge. A partially full tank costs less to refill because the customer pays for the propane added, not a full cylinder replacement.
Retail exchanges can be simpler than filling, but customers generally pay a posted exchange price and leave the old cylinder. Some exchange programs accept tanks from other brands if they are within program rules and in acceptable condition; damaged, expired, or visibly compromised cylinders may be refused. Confirm local terms before budgeting on an exchange.
For a portable grill tank, the normal labor line is $0 because the customer handles the cylinder; delivery and replacement parts are the more likely extras.
Tank size, fill status, and certification change the price
The 20-pound size is the common comparison point, but Walmart listings may include smaller camping cylinders, larger cylinders, and multipacks. A small 1-pound disposable bottle often costs $4-$9 individually, while multipacks can reduce the per-bottle price. These are not direct substitutes for a refillable grill tank: each holds much less propane and can cost more per usable gallon.
Capacity also affects the purchase decision. A 20-pound cylinder is suited to many portable grills and outdoor heaters, while 30- or 40-pound cylinders cost more and may not fit a standard grill compartment. Larger tanks are less convenient to lift and exchange. Check the appliance manual for the approved cylinder size and regulator connection before buying.
Condition and certification matter as much as size. New tanks usually cost more upfront than used or exchange cylinders, but a used cylinder should be inspected for corrosion, valve damage, and readable markings. Requalification rules can apply to older cylinders. Do not buy a low-priced tank with unclear condition or missing safety information simply to save a few dollars.
Fuel included is another major price threshold. A new empty tank at $50-$70 may look cheaper than a filled unit at $70-$95, but the buyer still has to pay for the first fill. Conversely, a “filled” tank may not be full to its safe capacity, so check the product description and the supplier’s stated fill amount. Price per gallon offers a better comparison when the quantities are known.
Compare capacity, usable fuel, valve condition, and fill status—not just the displayed tank price. A cylinder that fits the appliance and can be legally refilled is more useful than a lower-priced model with incompatible hardware or uncertain service eligibility.
Exchange or refill for the lowest ongoing tank price
A refill often costs less than an exchange when the cylinder is in good condition and the local station charges by the gallon. For a near-empty 20-pound tank, a typical $14-$24 fuel charge can undercut a $19-$25 exchange. The difference may be small, though, especially if the refill station has a minimum fee or is farther away.
An exchange can make sense when convenience matters, the cylinder is due for inspection, or a refill location is not nearby. The exchange operator provides a serviceable cylinder and takes the old one, subject to its rules. The customer gives up any remaining propane in the returned cylinder, so exchanging a partly full tank may be poor value.
Buying a new cylinder has the highest first-visit cost but gives the buyer a tank to refill repeatedly. A person who uses propane only once or twice a year may prefer an exchange rather than paying for a new cylinder and finding a fill station. A frequent grill user may find refilling more economical over time, particularly when a local supplier charges a competitive per-gallon rate.
For a sound, nearly empty tank, compare the actual refill total with the local exchange price before choosing. For a damaged or rejected cylinder, do not assume either service will accept it; ask the supplier about replacement and disposal procedures.
Delivery, fittings, and safety checks can add to checkout
Online listings can carry delivery charges, seller fees, or shipping restrictions because propane cylinders are regulated goods. Some listings may be available for store pickup while others cannot be shipped to a particular address. A product’s low advertised price may therefore not equal the amount paid at checkout. Check the seller, delivery terms, and pickup availability before comparing it with an in-store price.
Additional fittings are usually unnecessary when replacing a compatible grill cylinder, but a worn regulator or hose can add $15-$45. A connection that leaks, has damaged threads, or does not match the appliance should be corrected before use. Do not force a mismatched fitting or try to repair a tank valve yourself; have a qualified propane professional assess equipment that appears unsafe.
Inspect a cylinder for severe rust, dents, bulging, or valve damage before use. A retailer or propane supplier may refuse a cylinder that fails its safety checks. A replacement could cost $45-$80 for a new empty tank, while an acceptable exchange may be less. Local rules and supplier policies can affect whether an old cylinder can be exchanged, refilled, or must be handled through a designated disposal service.
Allow $0-$30 for possible delivery or handling and $15-$45 only if compatible grill parts need replacement. These costs are avoidable when the buyer picks up a suitable tank and the existing grill connection is in good condition.
Regional propane prices vary more than tank hardware
The cylinder itself is a packaged retail product, so regional differences are generally smaller than the differences in propane service, delivery, and local availability. A practical planning allowance is that a local price may be about 5%-15% above or below the ranges shown, especially in remote areas, high-cost metro markets, or locations with limited competing retailers. Store inventory and promotions can create larger short-term differences.
Refill prices are more sensitive to region and supplier than the tank’s purchase price. Rural customers may travel farther to find a fill station, while dense suburban areas may have several refill or exchange options. In colder regions, winter demand for propane can affect service availability and delivered-fuel pricing, though a standard portable-cylinder fill is not priced identically across all suppliers.
To compare quotes fairly, use the same tank size and the same fill quantity. Ask whether the refill price is per gallon, includes taxes, and carries a minimum charge. For exchange, confirm the posted total and whether the old cylinder qualifies. Walmart’s local shelf price can be compared with nearby hardware and farm-supply stores, but online prices may include different delivery terms.
Use the local refill or exchange charge—not a national average—as the deciding figure for recurring fuel purchases. A price difference of a few dollars can disappear if the cheaper supplier requires a long drive or charges a service fee.
Three sample budgets for common Walmart tank purchases
These examples show how the total changes with purchase type. They use typical ranges rather than a guaranteed store quote and exclude taxes where the local checkout does not show them separately. A buyer should verify current Walmart availability and the local fill or exchange price before making a trip.
| Purchase scenario | Price calculation | Estimated total | Budget note |
|---|---|---|---|
| New empty 20-lb tank, then refill | $55-$70 tank + $15-$24 fill | $70-$94 | First usable tank; fill charge varies by gallons |
| New filled 20-lb tank | $65-$90 cylinder with fuel | $65-$90 | Check stated fill amount and seller terms |
| Exchange an eligible empty tank | $19-$25 exchange | $19-$25 | Assumes customer already owns a qualifying cylinder |
In the first example, the buyer keeps a new tank and can use refill services in the future. The second prioritizes convenience, but the value depends on whether the included fuel amount is comparable to a full refill. The third has the lowest immediate expense because the cylinder itself is already owned; it is not comparable to buying a new tank from scratch.
Do not compare a $20 exchange directly with a $60 empty-tank purchase without accounting for the cylinder already owned and the fuel included. The cheapest quote depends on whether the shopper needs hardware, propane, or both.
Control the Walmart propane tank bill before checkout
First, identify whether the purchase is for an empty cylinder, a filled cylinder, or an exchange. This prevents comparing a tank-only listing with a fuel-included price. Then confirm the capacity, valve, and appliance compatibility. Buying the wrong size can turn a seemingly low price into a return trip or an unusable cylinder.
For an existing tank, compare local refill and exchange charges before replacing it. Refill only when the tank is accepted and in safe condition. If the tank contains a meaningful amount of propane, exchanging it may mean giving up the remaining fuel. If the cylinder is rejected, ask the supplier how to handle it rather than attempting to empty or dismantle it.
Check pickup against delivery and compare the final checkout total, including taxes and fees. A store pickup option can avoid shipping costs, while a marketplace listing may have different seller terms. If several cylinders are needed, compare multipacks and per-tank prices, but verify that each cylinder has the required size and specifications.
Skip accessories unless the existing hose or regulator is worn, leaking, or incompatible. Avoid buying a larger tank than the grill allows, and do not pay a premium for features that are not required by the appliance manual. Keep the receipt and product details in case the tank’s return, warranty, or exchange terms need to be checked.
The most reliable savings come from choosing the right capacity, checking the all-in price, and refilling a safe cylinder when local rates beat exchange pricing. A new tank is a separate equipment expense; recurring propane costs should be compared by gallons and service charges.
