The C2ER ACCRA composite index aggregates five spending categories. Looking at them individually shows where the Austin-to-San Diego 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 | Austin | San Diego | Delta |
|---|---|---|---|
| Housing Rent + median home price | 138 | 185 | +34.1% |
| Groceries Supermarket basket | 95 | 107 | +12.6% |
| Transportation Fuel, transit, parking | 102 | 127 | +24.5% |
| Healthcare Doctor visits, prescriptions | 98 | 102 | +4.1% |
| Utilities Electric, gas, internet | 104 | 113 | +8.7% |
| Composite | 117 | 146 | +24.8% |
The cost-of-living step-up from Austin, TX to San Diego, CA is about 25% on the composite index — large enough that it should reshape how you think about salary, savings rate, and lifestyle. $75,000 of Austin purchasing power requires about $93,590 in San Diego just to maintain parity. That is the minimum threshold before you call any San Diego offer a real raise.
The other dimension that often gets missed: savings rate compression. Even if your salary moves up proportionally, fixed costs like rent eat a larger share of after-tax income in higher-cost metros, which leaves less for retirement contributions and short-term savings. If you are currently saving 15–20% of gross in Austin and you move to San Diego on a proportionally-adjusted salary, expect that savings rate to drop into single digits unless you actively trim discretionary spending. Plan for that compression before signing the offer, not after the first month's rent check.
Tax is the silent leg of any cross-state move. Texas runs a 0.00% top-marginal or flat state income tax; California runs 9.30%. That maps to $0 versus $6,975 at the $75,000 anchor income — a $6,975 difference layered on top of the consumer-price comparison above.
Run your actual salary and filing status through the take-home pay calculator for a precise after-tax number. The federal layer is the same in either metro; only the state piece shifts. See the take-home pay calculator or the state-by-state take-home pay article for the precise after-tax number.
The data says yes. Composite indexes: Austin 117, San Diego 146. San Diego is roughly 25% more expensive overall, driven mostly by the housing sub-index with smaller contributions from utilities, groceries, and transportation.
Roughly $93,590 per year in San Diego matches what $75,000 buys in Austin, based on the C2ER ACCRA composite ratio of 1.25. The result is pre-tax — add the state-tax delta from the sidebar for the full after-tax comparison.
Housing is the largest line item in any cost-of-living comparison and the one with the most metro-to-metro variance. Austin's housing sub-index sits at 138; San Diego's is 185. That gap reflects rent and home-price differences captured in the C2ER ACCRA quarterly survey. Groceries (Austin 95 vs San Diego 107), transportation (102 vs 127), and utilities (104 vs 113) all contribute, but housing is the dominant factor.
They are tracked separately. The cost-of-living composite measures consumer prices; state income tax is a different axis. Texas and California can disagree on tax by several thousand dollars per year at typical salaries, and that delta stacks with — not into — the consumer-price gap above.
