What the cost-of-living calculators miss
Most tools flatten the Austin versus Atlanta comparison into a single percentage. That number hides almost everything that actually matters.
Atlanta is meaningfully cheaper than Austin on most axes except state income tax. Median home price runs $392,000 in Atlanta versus $548,000 in Austin, a $156,000 delta.
Georgia has a 5.39% flat state income tax as of 2026. Texas has zero. On a $200,000 single earner, that works out to roughly $10,800 a year more in Atlanta. Over a decade, that is $108,000 dollar-for-dollar, which erases most of the home-price advantage.
Property tax effective is similar: Atlanta 0.83%, Austin 1.80%. The Austin bill in absolute dollars ($9,900 on a $550K home) runs well above the Atlanta bill ($3,250 on a $390K home), which is the Atlanta advantage.
Insurance splits: Atlanta homeowners runs $2,105, Austin $4,456. Atlanta auto runs $1,970, Austin $2,228. Both are close enough that they do not change the verdict.
The bottom line on a $200,000 single earner: Atlanta and Austin come out within $3,000 a year of each other in total cost. Atlanta wins on purchase price, Austin wins on ongoing tax, and the wash is closer than most people expect.
