Cost of living in St. Anthony, Idaho

St. Anthony, Idaho has about 3,911 people. That count is a 2020–2024 Census average, not a headcount from one day.

A typical home is worth about $231,900.

HUD's fair-market rent for a 2-bedroom in Fremont County is $1,014 a month. That is the county number, not an apartment listing in St. Anthony. It runs from October 2026 through September 2027.

Idaho's prices sit at 95.5 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.

Idaho taxes wages. A typical combined sales tax is 6.0% as of January 1, 2026. That mix is statewide, not St. Anthony's exact store tax.

In July 2026, a typical Idaho home paid 13.73¢ per kilowatt-hour. That is a state average from EIA, not St. Anthony's bill.

EIA does not publish a Idaho 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 Idaho shares this price.
