Tax estimates use federal income tax brackets and the standard deduction for the selected filing status. Payroll withholding follows common Social Security and Medicare rates.
State and local taxes, retirement contributions, and benefit deductions are not included unless entered, so results are general estimates only.
Hourly conversions assume a standard 40-hour week and 52 working weeks unless you change those inputs.
Your payslip and employer records are the authoritative source. Use these tools for planning and comparison rather than as tax or financial advice.
