Cost of living in St. Johns, Arizona

St. Johns, Arizona has about 3,395 people. That count is a 2020–2024 Census average, not a headcount from one day.

A typical home is worth about $203,400.

HUD's fair-market rent for a 2-bedroom in Apache County is $1,071 a month. That is the county number, not an apartment listing in St. Johns. It runs from October 2026 through September 2027.

Arizona's prices sit at 100.7 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.

Arizona taxes wages. A typical combined sales tax is 8.5% as of January 1, 2026. That mix is statewide, not St. Johns's exact store tax.

In July 2026, a typical Arizona home paid 15.38¢ per kilowatt-hour. That is a state average from EIA, not St. Johns's bill.

EIA does not publish a Arizona gasoline price. The West Coast (PADD 5) Except California all-grades price was $5.167 a gallon on September 15, 2026. The weekly file does not include that series, so this is the monthly price. At 12,000 miles a year and 25 mpg, the index counts that as $2,480.16 a year. Those miles are our standard, not a Census figure, and every town in Arizona shares this price.
