Kerosene vs Propane Cost Per BTU: Price Comparison for Home Heating 2026
Home heating costs are driven by the price per unit of fuel and the fuel’s energy content. This article compares the cost per BTU for kerosene and propane, showing typical ranges for U.S. buyers, and explains the main price drivers and ways to reduce expenses.
Assumptions: standard residential heating needs, midwestern to southern U.S. regions, conventional 20-80 gallon kerosene tank or 120-500 gallon propane tank, normal access, and mid-range delivery.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Kerosene price per gallon | $3.20 | $4.60 | $6.00 | Wholesale tends to vary with crude oil prices |
| Propane price per gallon | $1.80 | $2.60 | $3.60 | Includes delivery in many regions |
| Kerosene energy content | 120,000 BTU/gal | 135,000 BTU/gal | 140,000 BTU/gal | Net calorific value approximate |
| Propane energy content | 91,600 BTU/gal | 91,600 BTU/gal | 91,600 BTU/gal | Constant widely cited value |
| Cost per million BTU (approx.) | $28–$34 | $38–$53 | $60–$90 | Based on energy content and per-gallon price |
Typical cost per gallon and per million BTU for kerosene and propane
Prices vary by region and season, but buyers commonly see kerosene costing more per BTU than propane in most markets. This block shows per-gallon costs and translates them into a per‑million‑BTU figure to aid budgeting for space heaters or boilers. The following ranges reflect U.S. averages and typical delivery scenarios.
Table: Per‑gallon pricing and BTU math
| Fuel | Price Per Gallon | BTU Per Gallon | Cost Per Million BTU | Notes |
|---|---|---|---|---|
| Kerosene | $3.20–$6.00 | 120,000–140,000 | $27–$60 | Higher end when crude markets surge |
| Propane | $1.80–$3.60 | 91,600 | $20–$40 | Generally cheaper per BTU than kerosene |
Assumptions: typical home heating loads, standard efficiency equipment, and standard delivery charges.
Major cost components within a fuel quote
Understanding the breakdown helps buyers compare offers rather than just the per-gallon price. Common components include materials (fuel), labor for delivery, permits or fees in some locales, and overhead or delivery charges. Delivery and taxes can shift the total by several percent to over ten percent.
| Component | Typical Range | Notes |
|---|---|---|
| Fuel (kerosene or propane) | $1.80–$6.00 per gallon | Depends on market and grade |
| Delivery/ trucking surcharge | $0.10–$0.25 per gallon equivalent | Often included in total price |
| Taxes | 0–8% variable by state | State and local rules apply |
| Permits/fees | $0–$50 per delivery | Occasional regional charges |
| Storage/ handling | $0–$0.15 per gallon | Depends on on-site storage needs |
| Warranty/service plan | $0–$0.10 per gallon equivalent | Optional |
Formula note: total cost ≈ (fuel price × gallons) + delivery + taxes + storage + optional services.
Variables that most influence price per BTU
Market pricing for fuels moves with crude oil, natural gas markets, and seasonal demand. The strongest variables include regional crude-linked pricing for kerosene and regional propane supply/demand cycles. Region and season can swing price per gallon by 20% or more outside the national averages.
Factors to watch:
- Regional supply disruptions or refinery outages
- Weather-driven demand spikes in winter months
- Operational efficiency of storage and dispersion networks
- Local regulations impacting delivery or disposal costs
Practical ways to cut fuel costs without sacrificing warmth
Cost-conscious buyers can reduce total outlay by tightening scope, choosing efficient equipment, and timing deliveries. Buy in mid-summer when demand is lighter and prices tend to be lower than peak winter spikes.
- Match fuel type to heater efficiency; consider upgrading to higher-efficiency units if fuel costs are sustained.
- Bundle deliveries to reduce multiple service charges when possible.
- Inventory management: avoid short-term stockouts that trigger urgent, higher-cost deliveries.
- Consider alternative fuel mixes or backup strategies if regional prices diverge.
Regional price deltas across the United States
Prices for both kerosene and propane can shift by region due to distribution costs, climate, and local taxes. Midwest and Northeast regions often see higher kerosene prices, while propane prices can be steadier but vary with supply routes.
| Region | Average Price Per Gallon | Notes |
|---|---|---|
| Northeast | Propane $2.50–$3.40; Kerosene $3.80–$5.50 | Cold-season demand influences pricing |
| Midwest | Propane $2.20–$3.20; Kerosene $3.00–$4.80 | Regional transport costs affect totals |
| Southeast | Propane $1.90–$3.10; Kerosene $3.50–$5.20 | Longer heating season variability |
| West | Propane $2.10–$3.00; Kerosene $3.20–$4.90 | Distribution and storage costs vary by state |
Assumptions: typical regional markets with standard delivery options.
Per-unit pricing and heater efficiency calculations
To compare costs meaningfully, convert to per million BTU. A standard kerosene gallon yields about 120,000 BTU, while a gallon of propane yields about 91,600 BTU. Propane often delivers lower BTU per gallon but can be cheaper per BTU depending on regional price and efficiency.
Example calculation snippet: if kerosene is $4.50/gal and provides 120,000 BTU, cost per million BTU = (4.50 × 1,000,000) / 120,000 ≈ $37.50 per million BTU. For propane at $2.60/gal and 91,600 BTU, cost per million BTU ≈ $28.39. These are illustrative figures; adjust for actual local prices and heater efficiency.
Common efficiency ranges by system type
- Forced-air furnaces: AFUE 80–95%
- Boilers: 82–98% (depends on modulating and condensing features)
- Space heaters: 70–95% depending on model and venting
Storage, delivery, and handling costs for fuels
Fuel storage and delivery logistics add to the bottom line. Tank size, delivery frequency, and on-site handling impact total cost. Annual storage fees or rental costs can equal several dollars per gallon stored over a season.
- On-site storage: 55–100 gallon kerosene or 250–500 gallon propane tanks commonly used for home heating.
- Delivery scheduling: weekly or biweekly during peak season may reduce emergency charges.
- Handling: special permits or safety inspections are rare but can occur in certain municipalities.
Three real-world quote scenarios with specs
Scenario A shows a midwestern home with a 1,500 square foot heating load using kerosene. Scenario B compares a small urban home using propane for a boiler. Scenario C reflects a rural home with a larger tank and seasonal demand.
| Scenario | Fuel | Gallons/Month | Unit Price | Delivery | Total Monthly Cost |
|---|---|---|---|---|---|
| A | Kerosene | 140 | $4.20 | $0.18/gal | $624 (approx) |
| B | Propane | 80 | $2.80 | $0.12/gal | $232 |
| C | Kerosene | 220 | $3.80 | $0.25/gal | $1,003 |
Assumptions: standard delivery only, no unusual taxes, and typical household usage patterns.
Cost drivers by fuel type and scenario
Different scenarios emphasize various cost determinants. For kerosene, supply disruptions and crude oil prices more strongly move the price per gallon. For propane, regional supply chains and weather-driven demand shifts are the main levers. If winter demand spikes, expect higher per-gallon rates and possible delivery surcharges.
- Kerosene-specific drivers: crude oil price, refinery margins, and distillation yield
- Propane-specific drivers: natural gas prices, feedstock availability, and storage capacity constraints
- Both fuels: storage tank integrity, regulatory fees, and seasonal delivery scheduling
Bottom line: compare per-gallon price, BTU content, and delivery terms together to estimate monthly heating costs accurately.
