Boise spent most of the last decade being described as a cheap alternative to the West Coast.
Some of that is still true and some of it is a few years out of date, and the difference matters if
you are making a decision on it.
Here are the published figures, and then — more usefully — what they leave out.
Boise against four western cities
| City | Reported monthly cost, moderate tier | How it compares to Boise |
|---|---|---|
| Salt Lake City | About $3,300 | Cheaper than Boise |
| Boise | — | The baseline here |
| Portland | About $4,000 | More expensive |
| Seattle | About $4,100 | More expensive |
| Denver | About $4,200 | Most expensive of these |
services. These are modelled household budgets, not measured spending, and different services
produce different numbers for the same city. Use them for direction, not for budgeting.
Housing, which is where the whole comparison actually lives
| Boise | Seattle | |
|---|---|---|
| Reported average home price | Around $563,800 | Around $885,000 |
| Reported average rent | Around $1,781 | Around $1,917 one-bedroom · $2,392 two-bedroom |
by source and by whether the figure is a mean, a median, a list price or a sale price — these
are not all the same measure.
Relocation guidance commonly puts the saving for someone moving from the coast at 20 to 30 per
cent. That is a real difference. It is also considerably less than the gap Boise had five years
ago.
The three things these numbers hide
Boise is no longer cheap in absolute terms. An average home price near $564,000
is not a bargain by any national measure — it is only a bargain relative to Seattle, Portland
and Denver. If you are moving from somewhere other than the West Coast, the comparison you have been
reading was not written for you.
Rent and purchase have moved differently. On these figures Boise’s average rent
sits close to Seattle’s one-bedroom rent, while Boise’s home prices sit far below Seattle’s. Renting
in Boise is much less of a discount than buying in Boise. Anyone planning to rent for a year before
buying should price that year on Boise numbers, not on the headline saving.
Salt Lake City is the comparison nobody runs. Every list compares Boise to
Seattle and Portland, because that is the migration story. On these published figures Salt Lake City
comes out below Boise — a larger metro, a bigger airport, and a lower modelled cost. If your
decision is genuinely between mountain-west cities rather than between Boise and the coast, that is
the number to check first.
What a cost-of-living index cannot tell you
These indexes model a standard household. They do not know whether you drive, whether your
employer pays a coastal salary, what your health insurance costs, or what happens to your state tax
bill. Idaho, Washington, Oregon, Utah and Colorado tax income very differently, and for a
higher-income household that difference can be larger than the entire modelled gap between two
cities.
Treat the table above as a starting direction. Then price the four things that will actually
decide it: your housing, your commute, your tax position and your salary at the other end.
Figures compiled in 2026 from published cost-of-living data including
published 2026 Boise cost-of-living data and
city-by-city cost-of-living comparisons.
Cost-of-living indexes are models, not measurements; different providers publish materially
different numbers for the same city in the same month, and housing figures depend heavily on whether
the source reports means or medians and list or sale prices. Nothing here is financial advice
— check current local data before making a decision on it.
