Cost of Living in Arlington

Salary.com's 2026 figure put Arlington's overall cost of living 43% above the national average (up 1% from 2025), consistent with the base Arlington record's disclosed cost-of-living index of roughly 135. RentCafe's separate 2026 figure described Arlington as 25% above the Virginia state average and 36% above the national average -- a genuinely different magnitude from Salary.com's 43% figure, though both agree on direction: Arlington runs meaningfully above average by any measure, not near or below it.
Housing Drives the Index, by a Wide Margin
Arlington housing costs run 105% above the national average per one 2026 source -- more than double the typical U.S. housing cost. Average monthly rent across all unit types is cited at $2,704, with a 1-bedroom apartment in the city center averaging $2,480/month versus $1,994/month outside the center -- a real, disclosed premium for the more central, transit-adjacent neighborhoods (Rosslyn, Clarendon, Ballston, Crystal City/National Landing) covered on the best-areas topic page. See the housing-market topic page for home-price detail.
Groceries and Healthcare Run Above Average; Confirm Which Figure Applies
Groceries run about 10% above the national average per one 2026 source. Healthcare services -- doctor visits and dentistry specifically -- run about 23% above the national average, a more meaningful premium than groceries and specific to Arlington (a different, Arlington-specific figure from the 19% cited for Denver in this project's companion build, not a copy-pasted regional estimate).
Monthly Household Budget Estimates
Salary.com's 2026 figures put Arlington's cost of living at $3,543/month for a single adult (including housing; $1,487/month excluding rent specifically) and $7,803/month for a family of four -- these exact figures also appear in the base Arlington record's consSummary. A separate source estimated a single adult may need roughly $87,204/year ($7,267/month) in pre-tax income to live comfortably in Arlington, a materially higher figure than the $3,543 baseline cost estimate above, reflecting a "comfortable" living standard rather than a bare cost floor -- both figures are disclosed rather than picking the more flattering one.
A Rare Partial Offset: Confirm Utilities Directly
Unlike some other high-cost metros in this project's build (Denver's utilities, for instance, run about 13% below the national average as a partial offset), this research pass did not find a reliable, independently sourced Arlington-specific utilities figure -- that gap is disclosed here honestly rather than filled with an assumed number carried over from a different metro.
Key takeaways
- Arlington's cost of living runs consistently above the national average, though sources disagree on magnitude: Salary.com cites 43% above (index ~135, matching the base record), RentCafe cites 25% above the Virginia state average and 36% above the national average.
- Housing is the dominant driver -- 105% above the national housing-cost average, with average rent at $2,704/month citywide and a real premium for city-center neighborhoods ($2,480/month for a 1BR vs. $1,994 outside the center).
- Groceries run about 10% above the national average; healthcare services (doctor visits, dentistry) run about 23% above -- a genuinely Arlington-specific figure, not carried over from another metro in this project.
- Monthly budget estimates: $3,543/month for a single adult and $7,803/month for a family of four (Salary.com, matching the base record's consSummary), against a separate 'comfortable living' estimate of about $87,204/year ($7,267/month) pre-tax for a single adult.
- No reliable Arlington-specific utilities figure was found this pass -- disclosed as a gap rather than assumed from a different metro's number.
