Boise: high income, low cost — a rare combo. Boise earns above the national median ($81,308 — for better or worse — vs $80,367) while keeping costs below average (index 99 vs 111). That combination is exceptionally rare — only 40 of 288 cities share it.
High income and low costs rarely coexist — but Boise pulls it off. At $81,308 median household income and a 99 cost index, residents enjoy purchasing power that 13% exceeds the national average. We found this pattern across 3 cities in Idaho using 2026 data.
What does daily life actually cost in Boise? Start with the 25% rent-to-income ratio — tight but manageable for most households. On the category level, Housing (index 99) is where the real savings show up, while Healthcare (index 100) is the line item most likely to surprise newcomers. Income at $81,308 and homes at $494,696 round out a profile that ranks #1 for clear reasons (that's pre-tax, of course). One to watch.
It's worth mentioning — though it's outside our data model — that cities with these economics tend to attract remote workers, which can push prices up over time.
If the first stat impressed you, this one grounds it. Across Idaho, the average cost of living index is 101 — 10 points below the national median. Known for pandemic migration boom has reshaped prices, the state offers 3 tracked cities with median rents averaging $1,739/month. That's $156 less than the national average of $1,895. In the context of rising national rents, this stability is worth noting. There's an argument to be made — and I think the data supports it — that the cities getting all the attention right now are exactly the wrong places to move. The spotlight drives migration, migration drives demand, demand drives costs, and eventually the value proposition disappears. Meanwhile, cities like this one keep quietly being affordable, and the people who find them early are the ones who benefit most.

Meanwhile, Healthcare is the standout at index 103, keeping costs manageable. The weak spot? Housing at 114.
