How These Calculators Work

Methodology: formulas use simplified federal bracket logic, state-rate assumptions, FICA, and direct cost-of-living index ratios.

Inputs: salary, filing status, state, hourly wage, city selection, and comp package values.

Datasets: salary bands, hourly ranges, state tax tables, and top-city cost-of-living indexes.

Limitations: estimates do not include every deduction, payroll policy, or local jurisdiction nuance.

Intended use: decision support and scenario planning, not tax filing or legal advice.
