Cost of Living in Dunwoody
Dunwoody's overall cost of living reads as above the national average across every source found this pass, though the sources genuinely disagree on the size of the premium -- readings range from a modest 5% above the national average to a much larger 33% above it. Housing is the clearest driver of that gap.

Learn moreCost-of-living indices disagree substantially on magnitude
Sources reviewed this pass cite Dunwoody's cost of living anywhere from 5% above the national average to 10% above it to, in the most recent report found, 33% above it (an index of 133) -- a genuinely wide, disclosed spread rather than one settled premium. All agree on direction (above the national average); none agree closely on magnitude.
Housing costs are the clearest, most consistent driver
One detailed breakdown puts Dunwoody's overall index around 105, with the premium concentrated specifically in housing -- the median home price cited as roughly 66% above the national median. This is consistent with Dunwoody's roughly $673K-$712K median sale price against a widely-cited ~$410K-$430K 2026 US national median (see housing-market), and mirrors the same housing-driven-premium pattern this dataset documents for Suwanee and Sandy Springs.
No Georgia state estate tax, and a flat, recently accelerated state income tax
Georgia's state personal income tax is a flat 4.99% as of 2026 -- see taxes for the fuller, genuinely tangled recent legislative history (HB 111 and HB 463) behind that number. There is no Georgia state estate or inheritance tax, though federal estate tax rules still apply regardless of state of residence.
A real corporate job base helps offset the premium for many residents
Unlike Suwanee in this dataset, Dunwoody's Perimeter Center office concentration gives many residents a real, local, high-paying job market to draw on rather than needing to commute out of the metro to justify these costs -- median household income here ($121,903) runs meaningfully above Suwanee's ($103,260), consistent with that local job-market advantage.
