What This Comparison Actually Tells You
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.
Napa, CA and Ann Arbor, MI sit in clearly different price tiers, separated by 11.7 RPP points. At this distance, treating the same nominal salary as equivalent would materially change purchasing power.
Rents leads the difference, with Ann Arbor 72.1 points lower than Napa. 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.
For a housing-sensitive move, validate the rent gap first: HUD Fair Market Rent and the actual unit size can overturn what the blended index implies. On the BEA ratio alone, $100,000 in Napa corresponds to $89,628 in Ann Arbor.
