The C2ER ACCRA composite index aggregates five spending categories. Looking at them individually shows where the Phoenix-to-Denver gap actually comes from — the headline number is an average that compresses larger category-level differences. National average for each sub-index is 100.
| Category | Phoenix | Denver | Delta |
|---|---|---|---|
| Housing Rent + median home price | 110 | 166 | +50.9% |
| Groceries Supermarket basket | 99 | 102 | +3.0% |
| Transportation Fuel, transit, parking | 99 | 105 | +6.1% |
| Healthcare Doctor visits, prescriptions | 96 | 104 | +8.3% |
| Utilities Electric, gas, internet | 105 | 96 | -8.6% |
| Composite | 103 | 128 | +24.3% |
Denver, CO is not a casual upgrade from Phoenix, AZ: the composite cost-of-living index runs about 24% higher, with housing leading the gap at roughly 51% above Phoenix's baseline. Utilities and groceries follow the same direction at smaller magnitudes. Transportation can either compress or amplify the gap depending on whether you are giving up a car (likely in dense Denver neighborhoods) or keeping one and paying Denver-rate insurance, parking, and fuel.
The right way to think about this move is in terms of trade-offs, not pure cost. Higher rent buys access to a different labor market, different professional networks, different cultural offerings. Whether that trade is worth it depends on what you do for work and how much of your time is spent inside the city versus on a screen at home. The cost-of-living delta is the price tag; the question this page cannot answer is whether the thing you are buying is worth it for your specific career arc.
State income tax is not part of the cost-of-living composite, but it is part of your real take-home math. Arizona's effective top rate is 2.50%; Colorado's is 4.40%. On a $75,000 salary the two states pull $1,875 and $3,300 respectively — a gap of $1,425 that compounds with the consumer-price difference.
Plug your real numbers into the take-home pay calculator to see the after-tax difference at your filing status and salary. Federal withholding is constant; the state side is what changes when you cross state lines. See the take-home pay calculator or the state-by-state take-home pay article for the precise after-tax number.
Yes. The composite cost-of-living index for Denver, CO is 128, compared with 103 for Phoenix, AZ. That puts Denver roughly 24% above Phoenix on the C2ER ACCRA composite, with housing accounting for the majority of the gap. Groceries, transportation, and utilities follow the same direction at smaller magnitudes.
Approximately $93,204. The math: $75,000 times the index ratio 1.24 (which is 128/103) equals the salary in Denver that preserves your real-terms spending power. State tax sits on top — handled separately in the sidebar above.
Look at housing first. Phoenix sits at 110 on the housing sub-index; Denver sits at 166. The other four categories (groceries 99 vs 102, transport 99 vs 105, utilities 105 vs 96) all move smaller absolute distances and rarely dominate the composite.
No — the composite cost-of-living index focuses on consumer prices and does not include state income tax. The state-tax sidebar on this page handles that adjustment separately. Arizona's flat or top-marginal state rate is layered against Colorado's, and the gap can be several thousand dollars per year at a typical salary level. Stack the consumer-price equivalence with the state-tax delta for the full after-tax picture.
