Propane summer fill prices commonly run about $2.00-$3.50 per gallon for residential bulk delivery, with many households paying around $2.75 per gallon before taxes or special fees. The final bill depends on gallons ordered, tank size, location, delivery access, and whether the supplier charges a minimum-delivery or service fee.

Summer propane fill prices by gallon and tank size
For a standard residential delivery in summer, a practical planning range is $2.00-$3.50 per gallon, with a midpoint near $2.75. A 120-gallon purchase at that midpoint costs about $330 before taxes and delivery charges. A household ordering 300 gallons would pay roughly $600-$1,050 at the range extremes, or about $825 at the midpoint.
These estimates assume a typical bulk truck delivery to an accessible, customer-owned tank and no unusual service work. The gallons delivered are not always the tank’s full rated capacity: propane tanks are generally filled to about 80% to leave room for expansion. A 500-gallon tank therefore commonly takes around 350-400 gallons when nearly empty, not 500 gallons.
Budget around $2.75 per gallon for a basic summer estimate, then confirm the delivered rate and fees with local suppliers. Low posted prices may require a larger order, a prepaid plan, or a specific customer arrangement. Assumptions: typical U.S. residential bulk delivery, standard access, no tank repairs, and fees excluded.
What a bulk propane delivery quote includes
A written quote can include more than the commodity price. Ask whether the rate is per gallon delivered and whether it already includes delivery, fuel surcharges, taxes, and account fees. Some providers advertise a low per-gallon rate but charge a separate delivery or minimum-order fee, making a small fill more expensive per gallon.
| Quote item | Common range | How it affects the bill | Pricing basis |
|---|---|---|---|
| Propane | $2.00-$3.50 | Main fuel charge | Per gallon |
| Delivery or route fee | $0-$40 | May be waived above a volume threshold | Per stop |
| Small-order or minimum fee | $25-$100 | Can apply when ordering below the supplier minimum | Per delivery |
| Tank or leak inspection | $0-$150 | Possible after a service interruption or system change | Per visit |
| Taxes and local charges | $0-$30 | Depends on jurisdiction and purchase size | Per bill |
For example, 80 gallons at $2.75 per gallon costs $220 before fees. A $45 small-order charge makes the effective price about $3.31 per gallon before tax. A 300-gallon delivery at the same posted rate costs $825, and a waived route fee keeps the effective price close to the quoted rate.
Compare the all-in total for the same number of gallons rather than comparing advertised per-gallon rates alone. Check whether the quote is fixed, subject to a day-of-delivery market rate, or tied to a contract.
How tank size and delivery volume shift your rate
Order volume can matter as much as tank capacity. Some suppliers set a minimum delivery of 100-150 gallons, while others impose an additional charge below 100 gallons. Larger orders may qualify for a lower price per gallon, but a discount is not guaranteed; the supplier’s route, contract terms, and local competition also affect the quote.
Tank size determines how much fuel can be added safely, not how many gallons a household must buy. A 120-gallon tank typically holds about 96 gallons at the 80% fill limit. A 250-gallon tank holds about 200 gallons, and a 500-gallon tank holds about 400 gallons. If the tank is already 25% full, the delivery will be lower than these maximum amounts.
Delivery access is another price driver. A truck that can reach the tank on a routine route generally costs less than a visit requiring a long hose, difficult positioning, or a special appointment. A hose run over roughly 100 feet, steep or muddy access, or a locked gate can prompt additional charges or require a different truck.
Ask for the minimum order, price breaks, and expected gallons based on the tank gauge before scheduling. A supplier may quote one rate at 100 gallons and another at 300 gallons, so request both if the tank can accommodate either order. Assumptions: common aboveground residential tanks; fill volume depends on the current gauge reading and required expansion space.
Do summer propane prices differ by state and delivery route?
Yes. Summer demand is often lower than winter heating demand, but local supply, transportation distance, taxes, and competition still create substantial price differences. A customer near a terminal or in an area with several suppliers may receive a lower quote than a rural customer whose delivery requires a long route or a small stop.
As a broad budgeting comparison, a competitive suburban market may land near the low or middle part of the $2.00-$3.50 range. Rural routes or regions with fewer suppliers can run about 5%-20% above a nearby urban quote, particularly for smaller deliveries. Some areas can fall outside these ranges because of supply conditions, state charges, or supplier pricing plans.
Statewide averages are useful only as a starting point. A price posted for a large purchase or a new-customer promotion may not apply to an existing account, a small order, or an outlying address. Get at least three local quotes using the same gallon quantity, delivery window, and tank arrangement.
Compare suppliers serving the exact delivery address; a statewide average cannot capture route fees or local minimums. Confirm whether a quote includes applicable taxes and whether the supplier owns the tank or requires a service agreement. Assumptions: regional comparisons are planning estimates, not a guaranteed premium or discount for every address.
How long does a summer propane delivery take?
A routine delivery usually takes about 15-30 minutes at the property, though dispatch timing can range from a scheduled time window to several days. The driver checks the tank, connects the delivery hose, adds fuel, and records the gallons. A new account, an inaccessible tank, or a delivery after the tank has run empty can require extra checks or a separate service visit.
Labor is generally bundled into the per-gallon rate or delivery charge, rather than billed as a separate hourly line. If a supplier does bill separately for service, a broad local rate may be $75-$150 per hour, with minimum visit charges. A leak check or restart appointment can add cost beyond a normal fill.
Routine fills are usually simpler and less costly than emergency deliveries or service calls after an outage. Schedule before the tank approaches empty, and provide clear directions to the tank, access instructions, and an accurate gauge reading.
When do minimum fees and tank checks raise the bill?
Small orders are more likely to carry minimum-delivery charges because the truck and driver make a full stop regardless of gallons delivered. Depending on the supplier, a delivery below 100 gallons may face a $25-$100 fee or a higher per-gallon price. Emergency or after-hours service can add another $50-$200 or more, depending on distance and dispatch policy.
Tank checks may also increase the total. If a tank has run empty, the supplier may require a leak test or system inspection before restoring service. A typical inspection might cost $50-$150, while repairs, regulator replacement, or line work are separate. Suppliers may also decline a routine fill if the tank is damaged, out of certification, or not accessible under local safety rules.
Tank ownership affects charges, too. A leased tank may come with a service agreement or a required supplier, while a customer-owned tank may allow more freedom to compare providers. Before switching, check for tank removal fees, contract terms, and any inspection required by the incoming supplier.
Ask about minimums, emergency rates, and inspection requirements before a low tank becomes an urgent call. Share the tank’s last delivery date and whether it has run completely empty; that information can change the service plan.
Is a summer tank fill cheaper than cylinder exchange?
Bulk delivery is generally less expensive per gallon than exchanging a grill cylinder, but the products and quantities differ. A typical 20-pound cylinder contains about 4.7 gallons of propane. At $18-$30 for an exchange, the effective price is roughly $3.80-$6.40 per gallon, and the customer often receives a cylinder that is not filled to its maximum legal capacity.
A refill station may charge about $3-$5 per gallon, or approximately $14-$24 to refill a nearly empty 20-pound cylinder, depending on local prices and the amount added. This can be cheaper than exchange when the customer owns a sound, in-date cylinder. Bulk residential propane at $2.00-$3.50 per gallon can be cheaper still, but home delivery is not a practical substitute for filling portable cylinders unless the supplier specifically offers that service.
Use a bulk tank for home heating and appliances; compare refill and exchange prices for portable grill cylinders. Cylinder condition, inspection dates, and the actual gallons dispensed affect the value, so compare price per gallon rather than price per container.
| Purchase type | Typical price | Approximate fuel amount | Effective price |
|---|---|---|---|
| Residential bulk delivery | $2.00-$3.50/gal | 100 gallons or more | $2.00-$3.50/gal before fees |
| Portable-cylinder refill | $3-$5/gal | Up to about 4.7 gallons | $14-$24 for a near-empty 20-pound cylinder |
| 20-pound cylinder exchange | $18-$30 | About 4.7 gallons or less | About $3.80-$6.40/gal at full volume |
Ways to lower the summer propane fill price
Compare the full quote from at least three suppliers, specifying the same delivery quantity and asking whether fees and taxes are included. If a provider offers volume pricing, compare the savings against the cost of buying more fuel than the household can safely store or reasonably use. Avoid choosing a large fill solely to qualify for a discount when the tank cannot accept it.
Schedule a routine delivery rather than waiting until the tank is nearly empty. This reduces the chance of emergency service charges and leaves time to choose a supplier. Ask whether the company has a summer pre-buy, fixed-price, or capped-price plan, but review enrollment fees, gallon commitments, cancellation terms, and the rate that applies if the household uses less than planned.
Keep the tank area reachable and clear of snow, brush, locked gates, and parked vehicles. For customer-owned tanks, maintain required inspections and address minor equipment issues before they disrupt delivery. If the home uses propane only for occasional cooking, compare the cost of maintaining bulk service with portable-cylinder refills, including annual tank rental or account charges.
The most reliable savings usually come from avoiding small-order and rush fees, not from chasing a headline rate. Request an itemized estimate showing price per gallon, delivery minimum, taxes, and any account or tank charges before approving the fill.
