Cost of living in Gillette, Wyoming

A typical home is worth about $264,500.

HUD's fair-market rent for a 2-bedroom in Campbell County is $1,039 a month. That is the county number, not an apartment listing in Gillette. It runs from October 2026 through September 2027.

Wyoming's prices sit at 92.7 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.

In July 2026, a typical Wyoming home paid 14.36¢ per kilowatt-hour. That is a state average from EIA, not Gillette's bill.

EIA does not publish a Wyoming gasoline price. For the week of October 12, 2026, the Rocky Mountain (PADD 4) all-grades price was $4.575 a gallon. At 12,000 miles a year and 25 mpg, the index counts that as $2,196.00 a year. Those miles are our standard, not a Census figure, and every town in Wyoming shares this price.
