Cost of Living in Jacksonville
Cost-of-living estimates for Jacksonville disagree unusually sharply -- from roughly 10% below the national average to roughly 9% above it, depending on the source and methodology. What's consistent across sources is that housing is the category pulling the overall figure down, while groceries run slightly above the national average.

This is a case where the range itself is the honest finding, not any single number. Salary.com's 2026 index puts Jacksonville at 108 against a national baseline of 100 (8% above average); a separate aggregator puts it at 109, or 1.1x the national index; but ExtraSpace's 2026 calculator and a RentCafe-linked figure put Jacksonville 7-10% *below* the national average, and a third RentCafe estimate puts it only 1% above. These aren't small rounding differences -- they span roughly 19 points on a 100-point index -- and likely reflect different market baskets and reference years rather than one source simply being wrong. Don't treat any single index number from this spread as precise.
Category Breakdown
One 2026 aggregation (Salary.com/HomeSnacks-style data) breaks the gap down by category: housing runs about 20% below the national average, utilities about 9% below, and healthcare about 17% below -- but groceries run about 5% above the national average. This pattern, if accurate, would explain part of the disagreement above: an index weighted more heavily toward housing skews lower, while one weighted more toward groceries or services skews the overall number higher.
Monthly Budget Estimate
Salary.com's 2026 figures estimate a monthly cost of living around $2,501 for a single person and $5,507 for a family of four in Jacksonville. Treat this as a planning baseline from one methodology, not a precise number for any individual household -- actual spend varies enormously by neighborhood within the consolidated city's ~874-square-mile footprint.
Housing Drives the Real Comparison
Whatever the headline index, Jacksonville's housing costs are genuinely the most affordable of the Florida Tier A+ markets researched so far (see the base "Living in Jacksonville" page and the housing-market and renting topic pages) -- that's the more reliable, well-sourced comparison point than any single cost-of-living index score.
Key takeaways
- Overall cost-of-living index estimates for Jacksonville range from roughly 10% below to roughly 9% above the national average depending on the source -- an unusually wide spread that should not be collapsed into one figure.
- Housing (-20%), utilities (-9%), and healthcare (-17%) are estimated below the national average by one source; groceries (+5%) run slightly above -- a pattern that may explain the disagreement between overall index scores.
- One 2026 estimate puts monthly cost of living around $2,501 for a single person and $5,507 for a family of four -- a planning baseline, not a precise figure.
- Jacksonville's relative housing affordability versus other Florida A+ markets is the more reliably sourced comparison point than any single cost-of-living index.
