How the math works
We start with gross salary, subtract federal income tax (2026 brackets after the $16,100/$32,200 standard deduction per IRS Rev. Proc. 2025-32), Social Security (6.2% on wages up to the $184,500 2026 wage base), Medicare (1.45%, plus 0.9% above $200,000), and Illinois state income tax using the 2026 brackets shown above. Pre-tax 401(k)/HSA contributions, local taxes, and state payroll programs are not included, so treat results as close estimates.
