What This Comparison Actually Tells You
Hilton Head Island-Bluffton-Port Royal, SC and Madison, WI are a photo finish on overall price level, only 0.7 RPP points apart. A salary conversion is therefore a fine adjustment, not evidence of a fundamentally different cost regime.
Goods creates the largest separation: Madison is 2.6 points lower. But services 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 remain below the U.S. benchmark of 100. This comparison chooses between two below-average price levels; “more expensive” here does not mean nationally expensive.
For a goods-led difference, remember that many tradable prices vary less by address than housing or labor-priced services. Use $99,255 in Madison as the BEA equivalent of $100,000 in Hilton Head Island-Bluffton-Port Royal, then replace the national basket with your own.
