Homeowners evaluating kerosene and propane for heating must weigh cost per Btu, not just price per gallon. This article details the typical price ranges, per-unit costs, and the main drivers that influence the final bill for U.S. buyers. The focus is on cost clarity, with practical ranges you can use when budgeting for winter heat.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Kerosene price | $4.00/gal | $5.50/gal | $6.50/gal | Typical retail range |
| Propane price | $3.00/gal | $4.25/gal | $5.00/gal | Includes standard delivery |
| BTU content | 135,000 BTU/gal | 135,000 BTU/gal | 135,000 BTU/gal | Kerosene |
| BTU content | 91,600 BTU/gal | 91,600 BTU/gal | 91,600 BTU/gal | Propane |
| Typical consumption | About 60-90 gallons/month in cold months | 70-110 gallons/month | 120+ gallons/month | Depends on home size and climate |
| Cost per 100k BTU | $3.00-$4.40 | $3.70-$4.80 | $4.50-$5.50 | Based on gallon price and BTU content |
Assumptions: Midwest or suburban labor rates, standard storage tanks, typical home with a midrange efficiency furnace or heater.
Cost Drivers: how much you pay per Btu with each fuel
Key driver is energy content per gallon combined with fuel cost per gallon. Kerosene delivers about 135,000 BTU per gallon, while propane provides about 91,600 BTU per gallon. When buyers compare costs, the relevant metric is cost per 100,000 BTU, which standardizes the comparison across fuels. At mid-range prices, kerosene typically runs roughly $3.00-$4.40 per 100,000 BTU, and propane runs about $3.00-$5.50 per 100,000 BTU depending on market and delivery terms.
| Fuel | Price Range per Gallon | BTU per Gallon | Cost per 100k BTU (approx) | Notes |
|---|---|---|---|---|
| Kerosene | $4.00-$6.50 | 135,000 | $3.00-$4.40 | Higher energy density helps per-100k-BTU cost |
| Propane | $3.00-$5.00 | 91,600 | $3.00-$5.50 | Lower energy density raises per-100k-BTU cost in some ranges |
Fuel cost dominates the monthly bill, but delivery, storage, and equipment matters add up. A typical quote breaks into four to six parts: fuel price (per gallon), delivery charge, storage equipment and maintenance, furnace or heater efficiency impact, and optional permits or service plans. The table below illustrates a common structure for a home heating fuel quote.
| Component | Typical Range | Notes | Per-unit basis |
|---|---|---|---|
| Materials (fuel) | Kerosen e: $4.00-$6.50/gal; Propane: $3.00-$5.00/gal | Primary driver | $ per gallon; $ per 100k BTU |
| Delivery/Service Fee | $15-$60 per fill | Flat or variable | Flat fee |
| Storage Equipment | $100-$350 initial, then minimal maintenance | Tank, lines | One-time/annual |
| Furnace Efficiency Impact | AFUE 80%-95% | Efficiency affects fuel use | % efficiency |
| Maintenance/Service Plan | $0-$150/year | Optional | Annual |
| Permits/Inspections | $0-$100 | Regional | Per job |
Seasonal demand, tank size, and system efficiency are the strongest levers. In cold months, delivery fees and fuel needs can spike. Tank size limits how often you refill, while an older furnace with lower efficiency increases consumption. A 80%-AFUE furnace vs 95%-AFUE can swing annual fuel use by 10%-30% depending on climate and thermostat settings.
- Tank size impacts refill frequency and delivery charges.
- System type: older oil-to-propane conversions or an efficient modern burner changes losses.
- Distance to supplier affects delivery cost and scheduling reliability.
- Regional climate controls monthly consumption patterns.
Prices vary notably by region and climate zone. Coastal markets with higher distribution costs and rural areas with limited suppliers can widen price ranges by 10%-25% from national midpoints. For example, kerosene may be cheaper in inland areas with strong refinery access, while propane price swings follow regional demand for heating and agricultural use throughout winter. Expect more volatility in propane during peak winter weeks and late summer refill cycles for security.
Standardized comparisons help buyers budget accurately. Converting per-gallon pricing to per-100k-Btu costs reveals the true energy value. At $5/gal kerosene and 135k BTU/gal, the per-100k-Btu cost is roughly $3.70. At $4.25/gal propane with 91,600 BTU/gal, the per-100k-Btu cost is about $4.63. Regional taxes, delivery timing, and plant efficiency can push these numbers higher or lower by a few tenths of a dollar.
| Scenario | Fuel | Gallons/Month | BTU Used | Estimated 100k BTU Cost |
|---|---|---|---|---|
| Midwest winter, average home | 60 | 8,100,000 | $3.50-$4.00 | |
| South region, lighter use | Propane | 40 | 3,664,000 | $3.50-$4.20 |
Control scope and timing to trim fuel bills. Prioritize upgrading furnace efficiency, sealing ductwork, and installing programmable thermostats to reduce wasted heat. If replacing equipment, choose a unit with higher AFUE and consider switching to a tank with better insulation. When comparing quotes, bundle delivery with equipment service to lock in lower rates. Simple steps like sealing air leaks and routine maintenance can reduce consumption by 5%-15% annually.
Prices shift with demand, weather, and supply cycles. Winter fronts see higher delivery fees and demand-based price spikes, while late fall promotions may trim costs before peak season. Build a budget that anticipates a 5%-20% fluctuation in monthly fuel costs, and lock in delivery terms early if possible. Consider off-peak ordering if available in your market to minimize price volatility.
Long-range cost considerations extend beyond monthly fuel bills. Storage equipment, regular upkeep of the heating plant, and potential tax incentives or rebates for efficient equipment or clean energy alternatives can influence total cost of ownership. Include a multi-year view: initial tank and furnace investments, plus annual fuel and service expenses. In some regions, tax credits can offset a portion of efficiency upgrades or heat pump conversions if eligible.
