Idaho's cost of living sits approximately 5–10% below the national average overall, though this figure masks significant variation between the rapidly growing Boise metro area and the state's more rural communities.
Boise has emerged as one of the fastest-growing cities in the nation over the past decade, driven heavily by remote workers and transplants from California, Washington, and Oregon seeking lower housing costs and a high quality of life.
This in-migration has pushed Boise-area housing prices up considerably from their historic lows, narrowing the gap with national averages.
Outside the Treasure Valley, cities like Twin Falls, Pocatello, and Idaho Falls remain meaningfully more affordable. Idaho does not tax Social Security benefits, making it increasingly attractive to retirees. The state's top income tax rate is 5.8% — reduced from higher levels in recent years.
Outdoor recreation, a strong agricultural economy, and growing technology sector in Boise make Idaho an increasingly competitive option for relocating households and businesses looking for a lower-cost Western alternative.
Idaho is frequently compared to the cost of living in Montana, the cost of living in Utah, and the cost of living in Wyoming — all Mountain West states attracting similar in-migration from higher-cost coastal states.
Those planning a move should also review 2026 cost of living increases to understand how budget planning is shifting nationwide.
Cost of Living Overview
BLS Mountain region CPI data indicates Idaho's overall cost index runs approximately 5–10% below the national average as of 2026, with the Boise-Nampa metro approaching the national average in housing and services due to sustained population growth.[1] Smaller Idaho markets including Twin Falls, Pocatello, and Coeur d'Alene (northern Idaho) offer meaningfully lower costs across housing, food, and services.
U.S. Census Bureau American Community Survey data places Idaho's median household income at approximately $62,000–$66,000, modestly below the national median.
However, significantly lower housing costs relative to the Pacific Coast states that many Idaho newcomers are leaving from means effective purchasing power is often higher than in-state income comparisons suggest.[2]
Housing Costs in Idaho
Housing is the most consequential cost category for Idaho residents, and it varies dramatically by location.
HUD Fair Market Rent data for FY2025–2026 shows two-bedroom FMR rates of approximately $1,300–$1,600/month in the Boise-Nampa metro, $900–$1,100/month in Twin Falls, and $850–$1,050/month in Pocatello and Idaho Falls.[3]
Boise median home prices have moderated after sharp pandemic-era appreciation but remain elevated, typically ranging from $380,000–$480,000 for single-family homes in the metro as of 2026.
Before purchasing, buyers should carefully assess how much house you can afford based on income, debt, and down payment.
Understanding mortgage amortization helps buyers see how much of each payment goes to principal vs. interest over time.
The mortgage interest deduction applies to qualifying Idaho mortgages, and homeowners insurance tax treatment is worth reviewing.
Suburban communities like Meridian, Nampa, Kuna, and Star offer modestly lower prices.
Northern Idaho markets like Coeur d'Alene have also appreciated significantly due to remote worker in-migration and proximity to Spokane, WA.
Twin Falls, Pocatello, and eastern Idaho cities remain considerably more affordable, with median home prices often in the $220,000–$320,000 range.
Boise Growth and Housing Supply
Boise's population growth rate has been among the highest of any US metro over the past decade, creating sustained housing demand that has outpaced new supply.
Active residential development in the Treasure Valley — particularly in Meridian and Ada County — has partially alleviated pressure, but affordability challenges persist in the core Boise market.
First-time buyers and lower-income households face more significant barriers than the statewide cost index suggests.
Food and Grocery Costs
Grocery costs in Idaho are generally at or slightly below the national average, benefiting from the state's significant agricultural production.
Idaho is a major producer of potatoes, dairy, wheat, trout, and various produce, which keeps local food supply chains competitive.
A single adult might typically spend $290–$400 per month on groceries.
Major chains including Albertsons (headquartered in Boise), Fred Meyer, WinCo, and Walmart Supercenter provide competitive pricing options.[1]
Dining Out in Idaho
Idaho's restaurant scene has grown considerably as the state's population has increased, particularly in Boise, which now offers diverse culinary options including farm-to-table restaurants, craft breweries, and international cuisine.
A typical casual restaurant meal in Boise runs $13–$20.
Idaho's 6% sales tax applies to restaurant meals with no additional prepared-food tax.
Smaller cities offer somewhat lower restaurant prices but fewer variety options.
Transportation and Utilities
Idaho is predominantly car-dependent.
Public transit exists in Boise through Valley Regional Transit but covers a limited geographic area and limited operating hours relative to the sprawling metro.
Auto insurance costs in Idaho tend to be below the national average, with full-coverage premiums typically running $1,400–$2,000 annually.
Gas prices in Idaho have historically been near the Mountain region average, with state gas tax at $0.33/gallon. Boise's Boise Airport (BOI) provides regional air connectivity, though most major hub connections require connections in Seattle, San Francisco, Denver, or Salt Lake City.[1]
Utilities in Idaho are generally affordable.
Idaho Power, the primary electric utility for southern Idaho, offers among the lower residential electricity rates in the Mountain West due to the region's significant hydroelectric generation capacity.
Average monthly electricity bills for a typical home run $80–$150.
Heating costs (natural gas or propane in rural areas) add $60–$150/month in winter months.
Outdoor Recreation as a Cost Consideration
Idaho's exceptional outdoor recreation — skiing at Sun Valley and Bogus Basin, whitewater rafting on the Salmon River, fishing, hiking, and hunting — is a major quality-of-life factor that draws residents.
Depending on lifestyle, outdoor recreation costs can add $100–$500+/month (season ski passes, gear, licenses) or remain minimal for those pursuing free access activities like hiking and fishing with basic licenses.
How Idaho Compares
The table below compares estimated monthly costs across key categories for Idaho versus the national average and two Pacific Coast states many Idaho transplants come from, based on BLS and Census data as of 2026.[1]
| Category | Boise, ID | National Avg | Portland, OR | Seattle, WA |
|---|---|---|---|---|
| Rent (2BR) | $1,350–$1,600 | $1,500–$1,900 | $1,900–$2,400 | $2,200–$2,800 |
| Groceries/month | $300–$400 | $350–$480 | $360–$500 | $380–$520 |
| Transportation/month | $600–$900 | $700–$1,000 | $700–$1,000 | $750–$1,100 |
| State income tax (top) | 5.8% | varies | 9.9% | 0% |
| Total (est. single) | $2,800–$3,800 | $3,200–$4,500 | $3,600–$5,000 | $3,800–$5,500 |
Healthcare Costs in Idaho
Healthcare costs in Idaho are moderately below the national average. ACA marketplace premiums for a benchmark silver plan for a 40-year-old run approximately $430–$580/month before subsidies. Idaho operates its own state-based health insurance marketplace (Your Health Idaho).
Rural healthcare access can be limited in much of the state, with Boise serving as a regional medical hub for southern Idaho. St. Luke's Health System and Saint Alphonsus Health System are the major providers in the Boise area.
Frequently Asked Questions
Is Idaho still affordable compared to California?
Idaho remains significantly more affordable than California, particularly in housing.
A Boise-area home that costs $420,000 would typically cost $700,000–$1,000,000+ in comparable California markets.
Idaho's income tax (5.8% top rate) is higher than California's flat impact for some income levels but substantially lower than California's top 13.3% rate for high earners.
Overall, most California transplants report meaningful cost-of-living improvement after relocating to Idaho.
Does Idaho tax Social Security benefits?
No. Idaho does not tax Social Security retirement benefits, making it more attractive for retirees compared to states that tax Social Security income. Idaho does tax other retirement income including IRA and 401(k) withdrawals at the state income tax rate of up to 5.8%.
What is the cheapest city to live in Idaho?
Pocatello, Twin Falls, and Idaho Falls are typically among the most affordable cities in Idaho.
These cities have median home prices often in the $220,000–$310,000 range and lower rental costs than Boise.
However, job markets in these cities are more limited, and residents typically need personal vehicles for all errands given limited public transit.
How has Boise's cost of living changed in recent years?
Boise experienced dramatic cost-of-living increases between 2018 and 2023, driven by a surge of in-migration from California, Oregon, Washington, and other states.
Home prices roughly doubled in some segments during the pandemic boom.
Since 2023, price growth has moderated significantly, but Boise housing remains elevated relative to its pre-2020 baseline.
The city is now closer to the national average in housing cost than it was historically, though still below the coastal metros many residents relocated from.
Is Idaho a good state for remote workers?
Idaho has become a popular destination for remote workers, particularly Boise, which offers a mix of affordable-by-coastal-standards housing, outdoor recreation, a growing restaurant and cultural scene, and reliable high-speed internet infrastructure.
Boise ranked highly on several remote worker destination indexes in recent years.
Remote workers relocating to Idaho from higher-cost states should review salary negotiation strategies to ensure their compensation isn't cut when their employer adjusts for geographic location.
The cost of living in Oregon is a useful reference point for Idaho transplants from the Pacific Northwest. Smaller Idaho cities may have more limited broadband infrastructure, though rural broadband expansion has improved connectivity in many areas.
