Where the Premium Lives in Idaho
None of the listed Idaho metros clears the U.S. benchmark. This is an in-state ranking of relative cost, not evidence that the leading metro is nationally expensive.
Boise City, ID and Coeur d'Alene, ID form a photo finish at the top, separated by only 0.1 RPP points. The useful signal is the cluster rather than the nominal first-place label; small release revisions could change their order without changing the state's expensive-market tier.
Below the leader, the next comparison tier is Coeur d'Alene, ID, Idaho Falls, ID, Twin Falls, ID *. Their order comes from overall RPP, while the table keeps goods, services, and rents visible so a reader can reject a superficially similar market with the wrong cost mix.
Local services is the component furthest from the national benchmark in Boise City, ID, but it remains below 100 at 70.7. In this state, “most expensive” can still mean least affordable only relative to nearby metros, not expensive compared with the country.
At Boise City, ID's price level, a national-average $100,000 lifestyle translates to about $98,391. Treat that as a purchasing-power screen, then verify occupation pay, current HUD rent, and state tax treatment before comparing an offer.
