Cost of Living in Franklin
Cost-of-living readings for Franklin cluster more tightly than in some markets -- most sources put Franklin modestly (3-4%) above the national average -- though one source's far higher "40% above average" framing appears to reflect a broader lifestyle-cost analysis rather than a standard index, disclosed here rather than treated as comparable to the others.

Learn moreMost sources agree Franklin runs modestly above the national average
Salary.com's April 2026 data put Franklin's cost of living 3% above the U.S. national average, and ERI's cost-of-living calculator cited 4% above national -- a real, if modest, premium consistent across two independently reviewed sources. A third source described Franklin as roughly 40% above the national average, but that figure appears to fold in broader lifestyle, childcare, and housing-driven factors beyond a standard cost-of-living index methodology, and is disclosed here as a genuine outlier rather than reconciled with the other two.
Housing, transportation, and food are the cited drivers
Sources attributing Franklin's above-average cost point to "soaring housing costs," elevated transportation expenses, and rising food prices as the specific drivers -- consistent with Franklin's status as the most expensive place in this dataset's five-city Nashville-satellite comparison batch (see the base record) even before this file's own fresher housing-market figures.
The most expensive place in this dataset's Nashville-satellite batch, and pricier than Murfreesboro/Smyrna by a wide margin
Franklin's median home price (see housing-market) sits well above Murfreesboro's and Smyrna's roughly $405K-$412K figures and above Hendersonville's roughly $512K figure cited in the base record's cross-suburb comparison -- though genuinely below Brentwood's still-higher price point, a real distinction worth keeping straight rather than treating the two Williamson County cities as interchangeable.
Zero state income tax is a real, structural offset
Tennessee's total absence of a state income tax on wages, retirement income, or Social Security is a genuine, structural cost advantage relative to income-tax states, worth weighing against Franklin's elevated housing costs and Williamson County's 9.75% combined sales tax rate (see taxes) when budgeting a move.
Key takeaways

- Franklin is the most expensive place in this dataset's five-city Nashville-satellite comparison batch, well above Murfreesboro, Smyrna, and Hendersonville -- but genuinely below Brentwood's still-higher price point.
