Net pay represents the residual earnings an employee receives after statutory and voluntary deductions are applied to the gross salary reported by an employer. Gross salary includes base wages, overtime, bonuses, and other compensation before any withholdings. Mandatory deductions—such as federal and state income tax, Social Security, Medicare, and unemployment insurance—are calculated based on legal formulas, while optional items like health insurance premiums or retirement contributions further reduce the amount that is actually deposited.
Employers typically present net pay on a pay stub alongside a breakdown of each deduction, allowing employees to trace how their earnings are transformed. Because tax brackets, benefit elections, and state regulations differ, two workers with identical gross salaries may see distinct net amounts. Understanding these variables helps individuals forecast cash flow, assess the true cost of benefits, and identify potential errors in payroll processing.
