What salary you'd need in Phoenix
To maintain your Denver purchasing power, here's what you'd need to earn in Phoenix.
Denver vs Phoenix: which makes more sense for you?
On paper, Denver's cost-of-living index of 129 runs roughly 18.6% higher than Phoenix's 105. But that headline number papers over real differences in how that cost is distributed — rent might be far more expensive while groceries and transit costs run closer to even.
The rent gap
A 1-bedroom apartment in Denver averages $1,850/month, vs $1,450/month in Phoenix — a -$400 difference. For 2-bedrooms, the gap widens to -$500/month. Over a year, the rent difference alone is $4,800 on a 1-bed.
Income context
Median household income in Denver is $69,452, while Phoenix runs $59,142 (-$10,310 difference). That matters for how the cost-of-living gap actually feels day-to-day — if local salaries are also higher, the cost difference washes out partly. If local salaries lag the cost-of-living gap, your paycheck buys noticeably less.
State tax differences
Denver is in Colorado and Phoenix is in Arizona, so you'll also pick up a state-tax difference. Tax-free states like Texas, Florida, Tennessee, Washington, and Nevada deliver real take-home upside even when nominal salaries are similar.
