What This Comparison Actually Tells You
Atlanta-Sandy Springs-Roswell, GA and Port St. Lucie, FL are a photo finish on overall price level, only 0.2 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Services creates the largest separation: Port St. Lucie is 9.2 points lower. But services and goods move against the overall direction, so this is a split budget rather than a clean across-the-board winner.
Comparable population context is incomplete for this pair, so no market-scale explanation is inferred from the price indexes.
Both metros exceed the U.S. benchmark of 100. The choice is between two national premiums, so local wages need to clear the higher baseline in either market.
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 Atlanta-Sandy Springs-Roswell to $100,170 in Port St. Lucie, but it is not a personal spending weight.
