Cheapest Cities in Montana

Where the Affordability Lives in Montana

The most affordable metro inside Montana is Billings, MT with an overall Regional Price Parity of 93.5, 6.5% below the national average of 100. Goods there index at 96.0, services at 72.4, and rents at 77.4 — and because rents carry the heaviest weight in the BEA formula, the low rent figure is typically what anchors a metro into the cheapest tier for its state.

Across the 5 lowest-cost Montana metro areas in this ranking, the average overall index is 97.0 and the average rent index is 99.8. 4 of these 5 metros sit below the U.S. national average, which tells you how much of a discount these areas really deliver relative to the country as a whole. The gap from Billings, MT (93.5) up to Bozeman, MT (102.5) inside this affordable list is 9.0 index points — a meaningful spread even among "cheapest" metros.

Translated into household budget, a nationally-priced $100,000 lifestyle in Billings, MT costs about $93,526, leaving room for savings, housing quality upgrades, or lower work hours compared to high-cost coastal metros. Keep in mind that a low RPP does not automatically mean low local wages — local earning potential, commute distance, school quality, and property taxes all stack on top of the BEA price index. For anyone considering relocation inside Montana, these cheapest metros are the right starting list, but always validate with rent tables and salary data specific to your occupation before committing.
