One hundred gallons of propane typically costs $250-$400 before special delivery or account fees, with an estimated national midpoint near $325. The final price depends on local fuel rates, delivery minimums, tank ownership, location, and whether the order is scheduled or urgent.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Propane for 100 gallons | $250 | $325 | $400 | About $2.50-$4.00 per gallon |
| Delivery or account fees | $0 | $25 | $75 | May be waived for qualifying orders |
| Estimated delivered total | $250 | $350 | $475 | Before taxes or special service charges |
What 100 gallons costs at typical delivered rates
At common residential rates of $2.50-$4.00 per gallon, 100 gallons of propane costs $250-$400 for the fuel itself. A reasonable planning figure is about $325, or $3.25 per gallon, before any separate delivery fee. Prices are estimates, not a fixed national tariff; providers can charge more in remote areas or during periods of tight supply.
For a standard scheduled residential delivery, budget about $300-$425 after ordinary fees. This estimate assumes an existing tank, normal truck access, and no tank rental, installation, leak repair, or special inspection. Assumptions: typical U.S. residential service, 100 gallons delivered, standard access.
A 100-gallon order means the amount of fuel delivered, not necessarily a tank filled to its rated capacity. Many tanks have a fill limit of about 80% to allow for propane expansion. The supplier measures the delivery in gallons and charges the account’s posted per-gallon rate.
How fuel, delivery, and tank charges appear on quotes
A quote can combine a variable fuel price with fees that apply to the account or delivery. Ask whether the quoted per-gallon price includes delivery, taxes, and any minimum-order charge. The table shows common ranges; fees differ by supplier and service agreement.
| Charge | Typical amount | How it is calculated | When it applies |
|---|---|---|---|
| Propane | $250-$400 | $2.50-$4.00 per gallon | 100 gallons delivered |
| Delivery fee | $0-$40 | Per trip or included in fuel rate | Depends on account terms |
| Small-order charge | $25-$100 | Flat fee or minimum purchase adjustment | If delivery is below the supplier’s threshold |
| Tank rental | $0-$200 per year | Annual charge, if applicable | Supplier-owned tank agreements |
| Taxes and surcharges | $0-$25 | Local charges or account-specific fees | Varies by jurisdiction and provider |
The per-gallon rate alone may not equal the final bill. A rented tank can carry an annual fee or require the customer to buy fuel from its owner. Customers with owned tanks may have more supplier choice, but still need to confirm that the provider can safely service the equipment.
Why region, tank ownership, and order size change the rate
Fuel prices often vary by region because of transportation distance, local competition, seasonal demand, and supply conditions. Rural customers can face higher delivery costs, while dense markets may have more competing suppliers. A quote can also rise when a delivery truck must travel farther than the provider’s normal service area.
Order size matters because some companies set a minimum delivery or add a small-load fee. For example, an order under 100 gallons may trigger a $25-$100 charge; another provider may require a 100- or 150-gallon minimum. Tank ownership also affects the available providers and account fees.
Confirm the per-gallon rate and minimum-order rule before comparing quotes. If a customer orders 100 gallons at $3.10 per gallon, fuel is $310; a $50 small-order charge would raise the bill to $360 before tax.
Local taxes, emergency service, and access can add further charges. A blocked driveway, steep or icy route, or long hose requirement may need special handling. Providers may quote those conditions individually, so the standard delivery price should not be assumed to cover unusual site access.
How far 100 gallons goes in a home
How long the fuel lasts depends on the appliances using it, outdoor temperatures, insulation, and household habits. A home using propane for cooking and hot water may use 100 gallons over several months. A propane furnace or whole-home generator can consume that amount much faster, especially during sustained cold weather or frequent outages.
For scale, a 90,000-BTU-per-hour furnace running at full input would use roughly 1 gallon of propane per hour. Actual furnaces cycle on and off, so this is not a daily consumption estimate. A technician or supplier can help estimate seasonal use from appliance ratings and prior delivery records.
Use past gallons per month to decide whether 100 gallons is a convenient order size. Compare the delivery amount with the tank’s usable capacity and expected use; ordering too little may lead to repeated fees, while ordering more than the tank can safely accept is not possible.
Urban and rural delivery prices differ by market
There is no dependable nationwide percentage that applies to every city and rural area. As a planning allowance, rural or remote deliveries may cost about 5%-20% more than a nearby competitive market, particularly when routes are long or orders are small. In some areas, strong local competition or a supplier’s seasonal contract can narrow that difference.
Regional price changes can also reflect weather and supply. Cold snaps raise demand in heating markets, while transportation disruptions can affect local availability. Compare current written quotes from providers serving the same ZIP code rather than relying on a national average alone.
A local delivered quote is more useful than a statewide average. Ask for the total on 100 gallons, the delivery date, and any minimum-order or annual fees so that competing offers can be compared on equal terms.
Delivered propane versus cylinder exchange pricing
Bulk delivery to a home tank is usually priced by the gallon, while grill-cylinder exchange is commonly sold as a fixed-price swap. A typical 20-pound grill cylinder holds about 4.7 gallons of propane, and exchange prices often run roughly $20-$30 per cylinder, or about $4.25-$6.40 per gallon by the nominal fill amount.
Buying enough exchanged cylinders to equal 100 gallons would require about 22 cylinders and could cost roughly $440-$660, before accounting for differences in cylinder capacity and fill level. That approach is generally not comparable to a bulk residential delivery: cylinders are intended for portable appliances, and a home system needs approved equipment and professional connections.
For a permanently installed home tank, compare bulk delivery with bulk delivery, not grill exchanges. Cylinder exchange can make sense for a grill when convenience matters, but it is usually a higher per-gallon route for large fuel quantities.
Ways to lower the 100-gallon propane bill
Ask suppliers for both their cash or spot rate and any pre-buy, fixed-price, or budget-plan options. Contract terms vary, and a fixed rate can protect against price increases while costing more if market prices fall. Check for enrollment fees, cancellation rules, minimum gallons, and whether the stated rate includes delivery.
Scheduling ahead can help avoid emergency or after-hours charges. Compare at least three local quotes using the same delivery quantity and ask each provider to list fuel, delivery, minimum-order fees, taxes, and tank charges separately. If the tank is rented, confirm whether switching suppliers would trigger a fee or require equipment changes.
The clearest savings often come from avoiding avoidable fees, not choosing the lowest advertised gallon price. Keep delivery access clear, order before the tank is nearly empty, and ask whether a larger delivery qualifies for a lower rate only if the tank has safe capacity and the household can use the fuel.
