The Flagstaff Chamber of Commerce gathers pricing information for a cost-of-living report which is then compiled by the Council for Community and Economic Research (C2ER).
According to the 2012 year end version of the report, the Flagstaff composite cost of living index was 111.6, or 11.6% more than the national average. The composite index reflects pricing in six categories: housing, groceries, utilities, transportation, health care and miscellaneous goods and services. Each category is weighted differently:
| Composite Index | Housing(27.02% of Composite) | Groceries(13.56% of Composite) | Utilities(10.30% of Composite) | Transportation(12.35% of Composite) | Health Care(4.60% of Composite) | Misc. (32.17% of Composite) |
| 111.6 | 140.2 | 111.7 | 91.4 | 105.2 | 99.8 | 98.2 |
