Cost of Living in St. Augustine
Cost-of-living estimates for St. Augustine cluster closer to the national average than in many Florida markets, but sources still disagree meaningfully on direction -- from about 5% below average to nearly 17% above, depending on methodology. Housing is the category most sources flag as running above the national baseline, even though the city's home prices sit below many other coastal St. Johns County communities.

Salary.com's 2026 index puts St. Augustine at 1% below the national average. PayScale puts it 5% below. HomeSnacks cites an index of 117 (17% above average, on a 100-point baseline). BestPlaces cites a Cost of Living score of 110.9 (10.9% above average). These sources span roughly a 22-point range on a 100-point index -- a genuine disagreement, not a rounding difference -- and likely reflects different market baskets and reference dates rather than one source being simply wrong.
Housing Costs: Sources Disagree on Direction, Not Just Magnitude
One 2026 estimate (BestPlaces-linked) puts St. Augustine housing costs 12.9% below the national average at roughly $1,045/month for a single person; a separate source puts housing costs 7% above the national average in the same period. Transportation runs about 15% below the national average per one source. This is a case where the range itself, not a single number, is the honest finding -- don't treat any one figure here as precise.
Monthly Budget Estimate
Salary.com's 2026 figures estimate a monthly cost of living around $2,450 for a single person and $5,394 for a family of four in St. Augustine -- a planning baseline from one methodology, not a precise figure for any individual household.
Tourism-Town Costs Aren't Fully Captured by These Indexes
Standard cost-of-living indexes measure groceries, housing, utilities, transportation, and healthcare -- they don't capture the tourism-driven pricing on downtown parking, dining, and retail that residents living near the historic core encounter more often than a typical suburban household would (see jobs-economy and traffic-transportation).
Key takeaways
- Overall cost-of-living index estimates for St. Augustine range from about 5% below to nearly 17% above the national average depending on the source -- a real spread that should not be collapsed into one number.
- Sources disagree even on the direction of the housing-cost comparison to the national average (one puts it 12.9% below, another 7% above) -- treat any single figure as approximate.
- One 2026 estimate puts monthly cost of living around $2,450 for a single person and $5,394 for a family of four.
- Standard cost-of-living indexes don't fully capture the tourism-economy pricing on parking, dining, and downtown retail that residents near the historic core encounter regularly.
