fin.payroll-processing Calculator
Calculates gross pay, FICA deductions, federal withholding, and net take-home pay for an hourly or salaried employee. Payroll calculations must account for pre-tax deductions (401k, health insurance) before applying FICA — the order of operations matters.
Inputs

Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Hours
Energy transferred by a force over a displacement (J = N·m).
Overtime Hrs
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
State Tax
Percentage paid as tax. After-tax return = pre-tax return × (1 − tax rate). Enter as a percentage (e.g. 25 for 25%).
