A good price for propane is usually about $2.50-$3.50 per gallon for residential delivery, though location, season, order size, and delivery fees can push the total outside that range. Small-cylinder refills and exchanges often cost more per gallon than a home tank delivery, so the fairest comparison is the full invoice divided by gallons received.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Home tank delivery | $2.00/gal | $3.00/gal | $4.50+/gal | Residential bulk delivery; fees and minimums may be extra |
| 20-pound cylinder refill | $15 | $22 | $30 | Usually holds about 4.7 gallons when filled to the safe limit |
| 20-pound cylinder exchange | $20 | $25 | $35 | Convenient retail exchange; often a higher effective gallon price |
| Small-order delivery | $25 fee | $50 fee | $100+ fee | Can apply when a truck visit is below the supplier’s minimum |
Assumptions: Typical U.S. residential pricing, standard propane, accessible tanks, and no unusual emergency or service charges. Local quotes vary.
What Counts as a Good Propane Price Per Gallon?
For a home tank, a quote around $2.50-$3.50 per gallon is generally competitive when it includes ordinary delivery and there is no large minimum charge. A rate under $2.50 can be a good deal in a lower-cost market or during a seasonal promotion; a price above $4.00 may still be plausible in a remote area, during peak winter demand, or for an urgent small delivery.
Compare the delivered price, not just the supplier’s advertised rate. Some companies quote a low per-gallon charge but add a delivery fee, fuel surcharge, hazmat charge, or minimum-order adjustment. Divide the amount due for propane and delivery by the gallons on the ticket to find the effective rate.
A practical benchmark is the invoice total divided by delivered gallons, with taxes and any recurring tank fee considered separately. For example, $390 for 120 gallons works out to $3.25 per gallon before any separately listed tax or tank rental.
Residential tanks are normally filled only to about 80% of capacity to leave room for liquid expansion. A “500-gallon tank” therefore does not usually accept 500 gallons during a routine fill; the amount needed depends on the gauge reading and the tank’s safe fill limit.
How Delivery, Labor, and Tank Fees Build the Invoice
A propane quote may combine the fuel rate with costs for truck service, account administration, equipment, and local tax. The table gives common planning ranges; suppliers differ in which charges they include in the per-gallon rate.
| Invoice component | Typical price | What changes the charge | How to compare |
|---|---|---|---|
| Propane | $2.00-$4.50 per gallon | Region, season, order volume, pricing plan | Check whether the rate is fixed or variable |
| Delivery | $0-$100+ per visit | Minimum gallons, distance, route, urgency | Ask if standard delivery is included |
| Tank rental | $50-$200 per year | Tank size, ownership, service agreement | Compare annual fee with purchase or lease terms |
| Service or leak check | $75-$200 per visit | Diagnostic work, repairs, local labor rate | Confirm whether inspection is required or optional |
| Taxes and surcharges | About $0.05-$0.50 per gallon | State and local rules, supplier fees | Request an itemized estimate |
Some suppliers waive a delivery charge when an order exceeds a minimum, commonly around 100-150 gallons, while others build delivery into the gallon rate. A low-volume customer may pay a higher effective price even when the posted propane rate matches a neighbor’s.
Tank ownership also affects the bill. A customer-owned tank may avoid annual rent but can require inspection, maintenance, or replacement at the owner’s expense. A supplier-owned tank may come with a rental fee and restrictions on purchasing propane from other companies.
Request a written quote that lists gallons, per-gallon rate, delivery minimum, fees, and tank charges. That makes competing offers comparable and helps identify a low headline rate that becomes expensive after add-ons.
Why Winter Demand, Tank Size, and Delivery Volume Change Rates
The biggest price swings usually come from when and how much a household orders. Propane demand rises in cold weather, particularly in regions where homes depend on it for heating. Suppliers may charge more during peak periods, and severe weather can delay routes or increase the cost of emergency service.
Order size matters because a truck visit costs money regardless of how many gallons are delivered. An order of 50 gallons can carry a much higher effective delivery cost per gallon than an order of 150 gallons. However, a larger fill is not automatically economical if it requires an unnecessary early payment or the supplier’s rate is not competitive.
Tank capacity and gauge readings help estimate a sensible order. A 500-gallon tank at 30% has roughly 150 gallons of liquid in it, while a 250-gallon tank at the same reading has roughly 75 gallons. Actual delivery is limited by the 80% fill rule and the tank’s condition.
Usage also changes the economics. A home using propane only for cooking may order infrequently and face minimum fees; a home using it for heat, hot water, and cooking may qualify for a volume plan. Many suppliers recommend scheduling delivery before the gauge reaches about 20%, rather than waiting for an emergency call.
Two useful quote thresholds are a 100-150-gallon delivery minimum and an 80% maximum tank fill. Ask how those rules affect the actual order, especially if the tank is small or the property is difficult for a truck to reach.
Control the Gallon Rate by Timing and Comparing Quotes
Customers can often reduce the effective price by arranging a routine delivery before winter demand peaks. Summer and early fall may offer more scheduling flexibility, but seasonal price patterns are not guaranteed: wholesale supply, weather forecasts, storage levels, and local competition all matter. A fixed-price plan can limit sudden increases, while a variable plan may fall when market prices decline.
Compare at least two or three suppliers using the same quantity and timing. Ask each for the per-gallon charge, delivery fee, minimum order, tank rent, contract term, and price-adjustment rules. A quote that is 20 cents per gallon lower saves $30 on a 150-gallon delivery, but a $40 delivery fee would erase that advantage.
Automatic delivery can reduce the risk of running out, but it may involve a service agreement or estimated usage. Will-call service gives the customer more control over order timing, though the customer must monitor the gauge and allow time for delivery. Review the agreement for cancellation fees and tank-pickup charges before switching suppliers.
The most dependable savings come from comparing the complete bill and avoiding emergency deliveries. Keep enough fuel in the tank to schedule a normal route, and do not choose a supplier solely on an introductory rate that may reset after the first delivery.
How Propane Prices Differ Across U.S. Regions
Prices vary with distance from terminals, local supply, competition, road access, and heating demand. As a broad planning comparison, rural locations can run about 10%-30% above nearby metro pricing when delivery routes are long or supplier choice is limited. Dense suburban areas may have more competing companies, but traffic, labor, and local operating costs can also raise service charges.
Cold-weather states can see sharper seasonal increases because more homes depend on propane for heat. In milder climates, households may use fewer gallons, but small orders can still carry a sizable delivery charge. These patterns are not a substitute for local quotes: even nearby towns can have different minimums and fee structures.
For a 150-gallon order, a delivered rate of $2.75 per gallon totals $412.50 before taxes and separate fees. At $3.50 per gallon, the same quantity costs $525, a $112.50 difference. Compare the same order volume and delivery window to separate regional pricing from differences in service terms.
Use regional percentages as a screening tool, not as a guaranteed local price. A supplier’s quote is most useful when it states the rate’s expiration date and whether it can change before the truck arrives.
Three Home-Tank Quotes and What Each One Really Costs
These examples show how fuel rate and delivery conditions affect a household invoice. They assume standard residential delivery and exclude taxes unless noted. The labor component is generally embedded in the delivery service rather than billed as a separate hourly line item.
| Scenario | Fuel calculation | Other charges | Estimated total |
|---|---|---|---|
| Routine 100-gallon order | 100 gal × $2.65 = $265 | $0 delivery fee | $265, or $2.65/gal |
| 150-gallon rural delivery | 150 gal × $3.10 = $465 | $35 route fee | $500, or $3.33/gal |
| Urgent 60-gallon delivery | 60 gal × $3.75 = $225 | $85 expedited visit | $310, or $5.17/gal |
In the first example, the supplier meets a standard minimum and includes delivery. The rural quote has a moderate gallon rate but a separate route charge. In the urgent example, the fuel itself is not the only issue: the expedited trip increases the effective price substantially.
For a household comparing a 150-gallon quote with a 100-gallon quote, the total bill alone is not enough. The larger order costs more upfront but may have a lower price per gallon, provided the tank can safely accept the amount and the customer is comfortable paying for fuel earlier.
Ask the supplier to show both the total and effective per-gallon cost for the expected delivery quantity. A simple estimate can also separate fuel from service charges:
Refill or Exchange a 20-Pound Propane Cylinder?
A refill is commonly about $15-$30 for a standard 20-pound grill cylinder, depending on the local per-gallon rate and whether the container is filled by weight or volume. A cylinder holds roughly 4.7 gallons at a proper 20-pound fill, so a $22 refill equals about $4.68 per gallon. The cylinder must be in acceptable condition and within any applicable inspection requirements.
An exchange commonly costs $20-$35, often for a cylinder containing less than a full 20 pounds. That can put the effective rate around $5-$8 per gallon, but the customer pays for convenience and avoids waiting while a cylinder is filled. Exchanges may include a usable cylinder, but terms vary by retailer and condition.
For frequent grilling, refilling an owned cylinder is often cheaper over time. For an occasional user who values speed, exchange can be reasonable if the container is empty, damaged, or not accepted for refill. Compare the actual fill weight on the label rather than assuming every exchanged cylinder contains a full 20 pounds.
Refill is usually the lower-cost choice per gallon; exchange is often the simpler choice per visit. Never refill a disposable cylinder, and transport and store cylinders upright in a well-ventilated area according to the supplier’s safety instructions.
Reduce Propane Charges Without Sacrificing Safe Supply
Plan deliveries around the supplier’s regular route and minimum order rather than requesting a small emergency drop. If the tank is low, ask whether combining fuel delivery with a scheduled service visit is possible. Keep the access path clear and provide accurate tank-location instructions so the driver does not need to make a second trip.
Compare fixed and variable pricing plans by considering the contract term, enrollment fee, cancellation conditions, and how often rates reset. A capped rate may cost slightly more upfront but provide predictability; a variable plan can be less expensive when market prices fall but exposes the customer to increases.
Review tank rental and service charges before switching. A lower gallon rate may not offset a new tank lease, installation charge, or removal fee. If a supplier owns the tank, the contract may require the customer to buy fuel from that supplier or pay to have the tank removed.
Households that use propane for heating can reduce consumption by sealing drafts, maintaining heating equipment, and using a thermostat schedule that fits the home. These steps lower gallons used rather than the supplier’s per-gallon rate, but the total annual propane bill can fall as a result.
Control the order size, delivery timing, and contract terms before focusing on minor fee differences. Preserve a safe reserve, follow the supplier’s guidance on tank levels, and avoid postponing a necessary delivery just to chase a lower rate.
