About Illinois propane prices
Illinois carries two propane loads that peak at different times. Grain dryers run in October and November across the central and northern counties, then home heating follows through the winter in the rural areas outside the Chicago gas system. The state sits at the northern end of the pipeline network that moves Gulf Coast barrels into the Midwest and has refinery and gas plant output of its own, which leaves it better supplied than states farther up the line.
EIA builds this number by calling retail dealers in Illinois each week of the October to March heating season and averaging what they report, published Wednesday afternoon. The survey stops for the summer and picks back up in October. Two lines run on the chart because EIA surveys Illinois dealers on both sides of the sale: what they pay at the rack and what they charge a residential customer. The lower line moves first, and the retail line follows it with a lag measured in weeks. The Census Bureau's American Community Survey, on five-year estimates, puts propane as the main heating fuel in 4.2% of occupied Illinois homes, below the national middle.
For context beyond one state, Illinois sits in the Midwest district: regional prices and Midwest propane stocks. The propane usage calculator will estimate your fill cost at this price: gallons per burner-hour from an appliance's rating, gallons a year, and how long a tank of a given size lasts between deliveries.
Common questions
What is the current propane price in Illinois?
Illinois's residential propane price is $1.948/gal as of Oct 26, 2026, the latest reading in EIA's weekly heating-season survey, with the wholesale (rack) price at $1.219/gal on Oct 26, 2026. The chart above carries the full history and the table shows the week-over-week move.
When is propane most expensive in Illinois?
In EIA's weekly survey, which runs October through March, Illinois's residential price set its season high in February in three of the last five heating seasons, January in one and March in one. The season low came in October in four of the last five heating seasons and March in one. From low to high the price moved an average of 29.5 cents a season, and the table above lists each season's high and low week. The regional wrinkle is that the Midwest season starts before the thermostat does: propane fires grain dryers across the Corn Belt in October and November, and a wet harvest can pull volume hard weeks ahead of heating demand. Why propane prices rise in winter has the mechanics.
How does the Illinois propane price compare with the Midwest average?
Illinois's residential propane price averaged below the Midwest average in each of the last five heating seasons, by between 14.2 cents and 18.6 cents a gallon. In the Oct 26, 2026 survey Illinois was at $1.948/gal against $2.199/gal for the Midwest average. The seasons table above gives the gap season by season, and Midwest propane prices carries the district's own chart.
What is the difference between the residential and wholesale price on this page?
The residential price is what an Illinois household pays for a delivered gallon: the dealer's own cost plus trucking, tank service and margin. The wholesale price is that dealer cost at the rack, before any of it. The gap between the two is the delivered-service stack, and how propane is priced walks through each layer of it.
