California vs Idaho: Cost of Living, Taxes, Rent and Safety Compared
Weighing a move between California and Idaho? Here’s how they compare on the numbers that decide most moves, from the same public data Locustep uses to rank all 50 states.
Shaded cells are the lower-cost, higher-income or lower-risk figure. Indexes: U.S. average = 100.
What it means for your budget
Rent alone: moving from California to Idaho changes a typical two-bedroom rent by −$1,265 a month (−$15,180 a year); the move the other way flips the sign. Taxes, pay, insurance and the move itself shift too, and how much depends on your income, your household and the city you pick.
That’s exactly what Locustep’s Net-Impact Report works out: your take-home pay after state and local taxes in both places, rent or buy for your budget, insurance and moving costs, and the month the move pays for itself.
Which state fits you better?
On Locustep’s directional scores, California leads on job market, healthcare, remote-work infrastructure, infrastructure and transport, walkability and airport access. Which of those matters depends entirely on you.
Where people look in each state
California
Los Angeles
$2,964/mo two-bedroom
Los Angeles is less a city than a hundred neighbourhoods stitched together by freeways — extraordinary food, beaches, mountains and creative industries, alongside severe traffic, a visible homelessness crisis and housing costs that dominate every budget. Car ownership is effectively mandatory.
San Francisco
$3,697/mo two-bedroom
San Francisco is dense, walkable, cool and foggy, with the highest concentration of tech capital anywhere. Expect exceptional food and transit by American standards, staggering rents, sharp street-level inequality, and a compact city you can cross in twenty minutes.
San Diego
$2,823/mo two-bedroom
San Diego has arguably the best climate in the country — mild, dry, coastal — plus a large military and biotech presence. It is expensive, sprawling and car-dependent, with a laid-back beach culture and comparatively few late-night options for its size.
Boise is a clean, outdoorsy, fast-growing high-desert capital with a river greenbelt through the middle and mountains just north. Formerly cheap and no longer, politically conservative statewide but moderate in town, with excellent air and easy access to wilderness.
Coeur d'Alene
$1,507/mo two-bedroom
Coeur d'Alene is a scenic lake town in Idaho's panhandle, popular with retirees and Washington transplants. Beautiful summers, snowy winters, a tourism-and-services economy, and housing costs that have climbed far faster than local wages.
Idaho Falls
$1,274/mo two-bedroom
Idaho Falls is an eastern Idaho city near Yellowstone and the Tetons, anchored by the Idaho National Laboratory. Cheap, quiet, family-oriented and heavily LDS, with a surprisingly strong engineering job market for its size.
On rent, Idaho is cheaper: a typical two-bedroom is $1,367 a month against $2,632 (HUD FY2027). Everyday costs, housing excluded, index at 103.9 in California and 98.0 in Idaho (U.S. = 100). Whether you come out ahead also depends on your pay and taxes in each state.
Which has lower taxes, California or Idaho?
Idaho. A married couple on the U.S. median household income would pay about 6.3% of it in state and local taxes, against 9.5% in California (Locustep estimate). Top income-tax rates are 13.3% in California and 5.3% in Idaho.
Is California safer than Idaho?
By violent crime, Idaho is lower: 230.6 per 100,000 residents against 486 (FBI, 2024). On natural hazards, FEMA puts California at the 87th percentile and Idaho at the 31st (lower is safer).
Which has better weather, California or Idaho?
It depends what you want. Winter afternoons average 68°F in Los Angeles and 41°F in Boise; summer afternoons 81°F and 88°F (NOAA 1991–2020). California: mild, mediterranean-style. Idaho: four distinct seasons.
