Why Nominal Salary Comparisons Are Misleading
If someone offers you $130,000 in New York City and $90,000 in Dallas, the Dallas offer might actually leave you with more disposable income. The BEA Regional Price Parities show that NYC costs roughly 130% of the national average while Dallas sits at about 97%. After adjusting for this, those two salaries deliver nearly identical purchasing power.
How to Calculate Cost-of-Living Adjusted Salary
The formula is straightforward:
Adjusted Salary = (Your Salary / Cost Index of Your City) x Cost Index of Comparison City
Example: You earn $90,000 in Dallas (index 97). What is the NYC equivalent?
$90,000 / 97 x 130 = $120,619. So your $90,000 in Dallas is equivalent to about $120,600 in NYC purchasing power.
Major City Cost Indices (BEA RPP 2024)
| Metro Area | Overall RPP | Housing RPP |
|---|---|---|
| San Francisco | 127.3 | 176.2 |
| New York City | 130.4 | 195.1 |
| Seattle | 116.2 | 147.8 |
| Boston | 114.8 | 145.6 |
| Denver | 107.1 | 123.5 |
| Austin | 101.3 | 107.2 |
| Dallas | 97.0 | 88.4 |
| Atlanta | 96.5 | 87.1 |
| Phoenix | 98.2 | 96.3 |
| Memphis | 86.2 | 62.8 |
Housing Is the Biggest Variable
Notice how the housing RPP varies far more than the overall RPP. NYC's overall cost is 130% of national average, but its housing cost is 195%. This means housing is where cost-of-living differences hit hardest. Groceries, transportation, and healthcare vary much less between cities.
When a Lower Salary Is Actually Better
Consider two job offers:
- Offer A: $140,000 in San Francisco (RPP 127.3)
- Offer B: $105,000 in Atlanta (RPP 96.5)
Adjusted to national average: SF = $109,900 effective. Atlanta = $108,800 effective. These are almost identical in purchasing power — but Atlanta's lower housing costs mean you would likely save significantly more money on the Atlanta salary.
Tax Differences Add Another Layer
Cost of living indices do not include taxes. California's top income tax rate of 13.3% vs. Texas's 0% state income tax adds another $5,000–$15,000 in annual difference for high earners. Always factor in both cost of living and state taxes when comparing offers across state lines.
