How we calculate California vs Kentucky

Tax engine. Federal income tax uses 2026 IRS brackets and the standard deduction for a single filer. FICA includes Social Security and Medicare employee shares. State income tax applies California's and Kentucky's rules as modeled in our US calculator (Progressive (top 13.30%) vs Flat 3.50%).

What's included. Wage income only — no capital gains, self-employment tax, itemized deductions, credits, or local city wage taxes (e.g. NYC) unless noted. Sales tax (~9.03% vs ~6%) and property tax (~0.7% vs ~0.74%) are context metrics, not subtracted from the take-home ladder.

Cost of living. COL indexes (140.5 vs 92.5, 100 = US average) and median household income ($93,500 vs $60,800) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the California → Kentucky relocation calculator.
