What This Comparison Actually Tells You
Port St. Lucie, FL and Coeur d'Alene, ID are a photo finish on overall price level, only 1.9 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Services leads the difference, with Coeur d'Alene 16.3 points lower than Port St. Lucie. Goods, services, and rents all point in the same broad direction, making the headline comparison more transferable across household types.
Comparable population context is incomplete for this pair, so no market-scale explanation is inferred from the price indexes.
This route crosses the national benchmark: Port St. Lucie is above 100 while Coeur d'Alene is below it. That makes the move a change of price regime, not merely a rank swap.
For a service-heavy household, test childcare, health, and other locally supplied costs before relying on rent alone. The BEA ratio converts $100,000 in Port St. Lucie to $98,069 in Coeur d'Alene, but it is not a personal spending weight.
