How paychecks are calculated

Last updated: December 31, 2025

Total Earnings (Gross Pay) – Pre-tax Withholdings – Taxes + Reimbursements = Amount Deposited (Net Pay)

For a more comprehensive understanding of the process, here are the following steps:

1. Compute the employee's gross income for the specific pay duration. This encompasses:

  • Base Salary

  • Tips Received

  • Commission Earned

  • Any Applicable Overtime

2. Deduct pre-tax contributions, which commonly encompass:

  • Premiums for Health Insurance

  • Health-related Account Deductions (e.g., FSA)

  • Contributions towards Retirement Plans (e.g., 401k or 403b)

  • Assistance for Childcare and similar expenses

The remaining balance after pre-tax deductions constitutes taxable wages. It's important to note that the definition of taxable wages can vary depending on the type of taxes involved.

3. Subtract employee-specific taxes, including:

  • Federal Income Tax

  • State Income Tax

  • Local Taxes (City and Regional)

4. Reduce other relevant taxes that both employees and employers contribute to. These may involve:

  • Social Security

  • Medicare

  • Contributions for Paid Family and Medical Leave

5. Account for additional post-tax deductions, whether voluntary or involuntary. These could include:

  • Wage Garnishments as mandated by court orders (e.g., child support)

  • Charitable Donations

  • Contributions to a 529 Savings Plan

6. Factor in reimbursements. These are integrated after tax deductions since they don't constitute earned income. Reimbursements are a repayment owed to employees for expenses incurred in relation to their work responsibilities.

7. The resultant sum represents net pay, signifying the actual amount the employee receives.
