How we calculate Delaware vs Arizona
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 Delaware's and Arizona's rules as modeled in our US calculator (Progressive (top 6.60%) vs Flat 2.50%).
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 (~0% vs ~8.54%) and property tax (~0.54% vs ~0.48%) are context metrics, not subtracted from the take-home ladder.
Cost of living. COL indexes (101.7 vs 107.6, 100 = US average) and median household income ($75,200 vs $71,200) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Delaware → Arizona relocation calculator.
