How we calculate Colorado vs Delaware
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 Colorado's and Delaware's rules as modeled in our US calculator (Flat 4.40% vs Progressive (top 6.60%)).
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 (~7.89% vs ~0%) and property tax (~0.5% vs ~0.54%) are context metrics, not subtracted from the take-home ladder.
Cost of living. COL indexes (101.8 vs 101.7, 100 = US average) and median household income ($89,800 vs $75,200) help interpret whether a paycheck win buys more in real life. For city-level equivalent salary, use the Colorado → Delaware relocation calculator.
