People can’t seem to get enough of those Idaho potatoes. Why do we say that? According to the most recent U.S. Census Bureau data, Idaho’s population grew at a rate of 8.8% over the last four years. Compared to the percent population growth across the entire country, which was just 2.6% during that same period, Idaho is growing by leaps and bounds.

Even though it has just over 2 million residents, Idaho still only averages around 14 people per square mile. Compared to California, which hosts 253 residents per square mile on average, Idaho is roomy!

Let’s take a closer look at what it costs to build a life in the Gem State.

What’s the Average Cost of Living in Idaho?

Average Cost of Living in Idaho: $46,270 per year

If you move to Idaho, you won’t be looking at a particularly expensive or particularly affordable lifestyle. According to the most recent Missouri Economic Research and Information Center (MERIC) data collected from the annual Council for Community & Economic Research (C2ER) survey, Idaho has the 32nd-lowest cost of living in the United States — the 18th highest, in other words.

For a lower cost of living, you might want to head to Montana, which ranked 22nd on MERC’s list, or to Wyoming, which has the 25th lowest cost of living per the C2ER survey.

While these rankings give a general idea of how expensive a state is to live in, you may still wonder: What is the average cost of living in Idaho?

You can expect to spend about $46,270 a year on total personal consumption, according to recent data from the Bureau of Economic Analysis . This is how that lump sum breaks down.

That’s about $3,856 in average monthly expenses for each Idahoan.

Housing Costs in Idaho

Average Housing Costs in Idaho: $963 to $1,772 per month

Housing is likely your biggest ongoing expense, no matter what state you live in. The typical Idaho home value was about $456,464 in February 2025, compared with a typical U.S. home value of $357,138 nationwide, according to Zillow.

Home sales in Idaho have settled down from a frenzied pace in 2021, when nearly 40% of homes sold above list price (an indicator that they received multiple offers). As of February 2025, just over 10% of homes sold above list price, showing a less competitive housing market per Redfin data.

Whether you own or rent, as well as how large your rental is, can affect how much you’ll spend monthly. Here’s what that spending might look like, according to the most recent census data:

•  Median monthly mortgage cost: $1,610

•  Median studio rent: $1,151

•  Median one-bedroom rent: $963

•  Median two-bedroom rent: $1,183

•  Median three-bedroom rent: $1,558

•  Median four-bedroom rent: $1,772

•  Median five-bedroom (or more) rent: $1,748

•  Median gross rent: $1,256

The specific area of Idaho you live in can also affect how much you’ll spend. These are the typical home values for some of Idaho’s major cities, according to recent Zillow data.

Health Care

Average Health Care Costs in Idaho: $7,507 per person, per year

Health care is a major expense in every state in the country. In Idaho, the average annual cost of health care is $7,507 per person, according to the most recent report of Bureau of Economic Analysis Personal Consumption Expenditures by State.

How much you would actually spend depends on location, medical needs, and coverage.

Child Care

Funding child care is a challenge for many parents, which isn’t surprising when you can spend around $1,000 a month on child care in states like Idaho.

Highest Marginal Tax Rate in Idaho: 5.695%

As of January 1, 2025, Idaho assesses a flat rate of 5.695% on taxable income, according to the Tax Foundation’s State Individual Income Tax Rates and Brackets.

Idaho’s flat rate of 5.695% is the second highest among the current flat tax states, of which there are 15 states, including Idaho (Washington state topped the list with a rate of 7%). The most recent ranking of State Tax Competitiveness puts Idaho at 11th among the most competitive tax systems.

High taxes do compel folks to seek greener pastures. In fact, in the last fiscal year, Idaho was the second most popular destination for Americans moving to new states where the taxes were lower.

Miscellaneous Costs

Now that we know what it costs to live in Idaho, let’s dive into what it costs to have some fun in this state.

•  A family visit to Craters of the Moon National Monument & Preserve in Arco, Carey, and Rupert, Idaho: $20 a day, for seven consecutive days, for a group entering in a single private vehicle. Visit historic lava flow sites, caves, and more in this “weird and scenic landscape.”

•  A 25-minute narrated ferry boat tour of the Snake River near Idaho Falls: $8-$40, varies by weight (kids under 30 lbs ride free).

How Much Money Do You Need to Live Comfortably in Idaho?

What it means to live “comfortably” in Idaho will depend on your lifestyle, income, family size, and more. That said, you can get a general idea of how accessible living comfortably is in each state.

Idaho ranks 23rd on U.S. News & World Report’s Affordability Rankings, which measure the average cost of living in each state against the average amount of money most households have there. The state came out higher on the magazine’s overall ranking, however, as the 5th best state overall.

MERIC viewed the affordability in Idaho less favorably, ranking the state as having the 32nd lowest cost of living in the United States (or 18th highest).
