What This Comparison Actually Tells You
Trenton-Princeton, NJ is 7% more expensive than Missoula, MT, a meaningful but not extreme shift. The move decision turns on which budget category creates the 6.7-point overall gap.
This route crosses the national benchmark: Trenton-Princeton is above 100 while Missoula is below it. That makes the move a change of price regime, not merely a rank swap.
Services leads the difference, with Trenton-Princeton 40.2 points higher than Missoula. 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 service-heavy household, test childcare, health, and other locally supplied costs before relying on rent alone. The BEA ratio converts $100,000 in Missoula to $106,983 in Trenton-Princeton, but it is not a personal spending weight.
