Cost of Living in Allen
Allen runs meaningfully above both the national and Texas-statewide cost-of-living averages -- BestPlaces.net's 2026 index puts Allen at 111.7, meaning overall costs run 11.7% above the U.S. average and 18.6% above the Texas average. That's a genuinely different picture than Dallas proper, which this site's Dallas-stack research put close to parity with the national average (BestPlaces 100.2) -- Allen's premium is real and largely traceable to housing.

Learn moreThe Overall Index and What Drives It
BestPlaces.net's 2026 cost-of-living index scores Allen at 111.7 against a national baseline of 100 -- 11.7% above the U.S. average and 18.6% above the Texas state average. This is a meaningfully higher reading than Dallas proper's near-parity 100.2 score in this site's Dallas-stack research, consistent with Allen's position as an established, top-schools suburb rather than a large metro core with a wide range of submarket price points.
Housing Carries Most of the Premium
As detailed on the housing-market page, Allen's median home sale price runs around $499,000-$500,000 as of mid-2026, cited by Redfin as 41% above the national median sale price -- housing, not groceries or transportation, is the main driver of Allen's above-average cost-of-living index. Renters see a somewhat smaller premium: see the renting topic page for specific 1- and 2-bedroom figures.
No State Income Tax, Offset by Property Tax and Insurance
Texas's lack of a state personal income tax applies to Allen the same as anywhere else in the state, and it's a genuine structural advantage on take-home pay. It does not offset Allen's property-tax bill or homeowners-insurance costs for owners specifically -- Collin County-area effective property tax rates and North Texas's hail-driven insurance costs both run above the national average (see the taxes and insurance-hazard-costs topic pages), and those costs land more heavily on Allen's owner-occupied, family-suburb housing stock than they would on a renter-heavy urban core.
Household Income Context
Allen's median household income is cited at $130,901 for 2024 by one aggregator (Neilsberg, based on Census ACS data), while a separate source (Allen Economic Development Corporation) cites $118,254 -- a real disagreement between sources, likely reflecting different reference years or geographies (city limits vs. a broader labor-market draw area). Either figure sits well above the U.S. median household income, which helps explain how Allen sustains a cost-of-living index well above the national average without pricing out the market -- but it's a genuine gap between two named sources, not a typo, and worth disclosing as such.
Key takeaways
- Allen's BestPlaces.net cost-of-living index is 111.7 for 2026 -- 11.7% above the U.S. average and 18.6% above the Texas state average, meaningfully higher than Dallas proper's near-parity 100.2 score.
- Housing is the main driver of the premium: Allen's median home sale price (~$499K-$500K) runs about 41% above the national median per Redfin.
- No state income tax is a real structural advantage, but it doesn't offset Allen's above-average property tax and homeowners insurance costs for owners specifically.
- Median household income is disputed between two named sources -- $130,901 (Neilsberg, 2024 ACS-based) vs. $118,254 (Allen Economic Development Corporation) -- both are well above the U.S. median either way.
