HUD's fair-market rent for a 2-bedroom in Iroquois County is $930 a month. That is the county number, not an apartment listing in Onarga. It runs from October 2026 through September 2027.

Illinois's prices sit at 100.0 when the U.S. average is 100. This place is not in a metro area with its own index, so this is the state number from BEA for 2024.

EIA does not publish a Illinois gasoline price. For the week of October 12, 2026, the Midwest (PADD 2) all-grades price was $4.237 a gallon. At 12,000 miles a year and 25 mpg, the index counts that as $2,033.76 a year. Those miles are our standard, not a Census figure, and every town in Illinois shares this price.
