Charleston, SC vs Austin, TX Cost of Living (2026)

Austin has a cost of living index of 95.6, about 4.4% below the national average. The housing index is 96.8, so housing still does a lot to shape the local budget. Typical apartment rent is about $1,774 a month, and median home values are around $492,364. The median household income is approximately $88,000.

A $100,000 salary in an average-cost city stretches to about $104,600 in Austin. The difference is real, but it is small enough that housing choice matters more than the metro average by itself. Most day-to-day categories stay close to the national baseline.

Texas has no state income tax, which is a real financial advantage. At a $100,000 gross salary, the absence of state income tax puts several thousand additional dollars in take-home pay compared to someone earning the same amount in a state with a 5 to 10% income tax. That advantage partially explains why Austin has attracted significant corporate relocations and individual migration from higher-tax states.

Property taxes in Texas are notably high and represent an important offset to the income tax advantage. Effective property tax rates in the Austin metro often run 1.8 to 2.2% of assessed value annually. On a $500,000 home, that's $9,000 to $11,000 per year in property taxes alone, on top of a mortgage. Buyers evaluating affordability should include the property tax figure explicitly in their monthly cost calculations, as it represents a cost that is materially higher than in most other states.
