Filling a home heating oil tank usually costs about $350-$1,375, depending mainly on gallons delivered and the local price per gallon. For budgeting, a typical delivery runs around $4.25 per gallon; tank size, how empty it is, delivery minimums, and regional fuel prices can change the total.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Heating oil per gallon | $3.50 | $4.25 | $5.50 | Planning range; local prices change |
| 100-gallon delivery | $350 | $425 | $550 | Before any delivery or service fee |
| 275-gallon tank refill | $350 | $850 | $1,375 | Assumes roughly 100-250 gallons delivered |
| Delivery minimum | $350 | $425 | $550 | Often 100 gallons or a minimum charge |
What a 275-gallon home heating tank costs to refill
A common 275-gallon residential tank does not necessarily take 275 gallons at each delivery. If it is ordered at one-quarter full, a delivery of about 200 gallons could cost $700-$1,100 at the planning rates above. A 100-gallon top-up would run about $350-$550, while filling a nearly empty tank to its safe capacity may require approximately 250 gallons.
For a typical delivery, budget by gallons ordered rather than the tank’s listed capacity. Tank gauges are approximate, and suppliers may leave room for expansion instead of filling to the brim. Assumptions: standard residential heating oil, ordinary delivery access, and no tank repair or emergency service.
How gallons, fuel price, and delivery charges shape the bill
The fuel itself generally accounts for most of the invoice. The delivered price per gallon may reflect the supplier’s current wholesale costs, local competition, delivery area, and whether the customer has a fixed-price or capped-price plan. Ask whether the quoted rate includes taxes and fees before comparing suppliers.
| Quote item | Typical range | How it affects the total |
|---|---|---|
| Heating oil | $3.50-$5.50 per gallon | Multiply by delivered gallons |
| Standard delivery fee | $0-$50 per stop | May be included in the gallon rate |
| Small-order or minimum charge | $0-$75 | Can apply when an order falls below the supplier minimum |
| Emergency or after-hours visit | $50-$200 extra | Depends on timing and supplier policy |
Compare the complete invoice total, not just the advertised per-gallon rate. A low rate can be offset by a service fee or a higher minimum order. For example, 100 gallons at $4.10 per gallon plus a $40 fee totals $450, or $4.50 per delivered gallon.
Why tank size and order thresholds change the quote
Two home-specific details matter: usable capacity and the supplier’s minimum order. A 275-gallon tank may hold less than its nominal capacity safely, and a 330-gallon tank can require a larger delivery when the gauge is low. Many suppliers set minimums around 100-150 gallons; an order below that amount may be declined or charged at a higher effective rate.
Fuel use also depends on the home and weather. A well-insulated house may use far less oil than a drafty home with an older boiler. A delivery of 150 gallons at $4.25 per gallon is $637.50, while 250 gallons at the same rate is $1,062.50. Every additional 50 gallons adds about $175-$275 at the planning price range.
Regional oil prices and delivery access can add 10%-25%
Heating oil is most common in the Northeast, but prices vary by state, supplier, and distance from distribution terminals. Urban and suburban customers with several nearby suppliers may find more competing quotes; rural addresses or long truck routes can face higher delivery costs. In a high-demand local market, the same 200-gallon order may cost 10%-25% more than a lower-priced comparison area.
Hard-to-reach fill pipes, steep or narrow driveways, and limited truck access can require special arrangements. These conditions do not always add a fee, so customers should confirm access requirements and any charge before scheduling. Ask for a delivered price to the exact address and tank location.
When can a small refill cost more per gallon?
Small orders can carry a higher effective price because the truck stop and route still require time even when fewer gallons are delivered. A 75-gallon order at $4.25 per gallon is $318.75 before fees; a $50 small-order fee raises the effective cost to about $4.92 per gallon. Suppliers may instead require a 100-gallon minimum, so check the policy before placing a partial fill.
Delivery labor is usually included in the fuel or service price rather than billed as a separate hourly job. When a separate trip or service call is quoted, confirm the charge in writing. Scheduling a routine delivery usually avoids the extra expense of an urgent stop.
Three delivery examples for common tank situations
| Situation | Gallons and rate | Estimated total | Assumption |
|---|---|---|---|
| Small top-up | 100 gallons at $4.25 | $425-$475 | Possible fee of up to $50 |
| Quarter-full 275-gallon tank | 200 gallons at $4.25 | $850-$900 | Standard delivery, possible stop fee |
| Nearly empty 275-gallon tank | 250 gallons at $4.25 | $1,062.50-$1,112.50 | Usable tank capacity varies |
These examples use a middle-of-range fuel price and show how order size drives the bill. At $3.50 per gallon, 200 gallons would be $700 before fees; at $5.50, it would be $1,100. Confirm the amount the supplier expects to deliver based on the gauge and tank setup.
How to lower the next heating oil delivery bill
Request quotes from multiple local suppliers using the same gallon quantity and delivery timing. Ask whether the price is cash, contract, or automatic-delivery pricing, and whether membership, payment, or stop fees apply. If the supplier has a minimum, a planned larger delivery can reduce the cost per gallon compared with several small orders, provided the tank has safe capacity.
Routine scheduling, clear access to the fill pipe, and checking the gauge before ordering can prevent rush charges and mistaken order sizes. Compare fixed-price plans with market-rate deliveries using the stated fees and contract terms; a fixed rate is not automatically cheaper. The most reliable savings come from comparing total delivered prices and avoiding unnecessary emergency service.
Fuel plans, tank service, and fees worth checking
Some suppliers offer automatic delivery, budget billing, or service plans. Automatic delivery can reduce the chance of running out, but the plan’s price, minimums, and cancellation terms should be compared with regular orders. Budget billing spreads payments across the year; it changes payment timing, not necessarily the total fuel expense.
Oil leaks, a damaged tank, or a burner problem are separate from the cost of filling the tank. A diagnostic or service visit may cost roughly $100-$250, with repairs or tank replacement priced separately. Ask for a separate estimate before approving tank or burner work. A fuel delivery quote should identify gallons, per-gallon price, delivery fees, and any service charges.
