Common Scenarios
Living on $100,000 in Arizona
Arizona has one of the lowest flat state income tax rates in the country at just 2.5%, fully phased in in 2023. The median household income in Arizona is approximately $74,568 — meaning a $100,000 salary is $25,432 above the state median, and $19,390 above the US national median household income of $80,610.
Arizona's cost of living index is 103 (US average = 100), so your $77,083 net pay has the purchasing power of approximately $74,837 in an average-cost state. Phoenix, Tucson, and Mesa all sit near the national cost-of-living average.
Living on $100,000 in Phoenix
In Phoenix — Arizona's economic hub for tech, aerospace, and healthcare — a $100,000 salary translates to roughly $6,424 in monthly take-home pay. The average 1-bedroom asking rent is around $1,450/month, which would consume about 22.6% of your net income. That's comfortably within the 30% rent-to-income guideline.
