What This Comparison Actually Tells You
Services creates the largest separation: Naples-Marco Island is 68.0 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.
Naples-Marco Island, FL is 2.9% more expensive than Amherst Town-Northampton, MA, a meaningful but not extreme shift. The move decision turns on which budget category creates the 3.0-point overall gap.
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.
Comparable population context is incomplete for this pair, so no market-scale explanation is inferred from the price indexes.
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 Amherst Town-Northampton to $102,950 in Naples-Marco Island, but it is not a personal spending weight.
