A payroll deduction plan is an arrangement that lets you automatically redirect a portion of your paycheck toward savings, investments, or other financial goals before the money ever hits your bank account. Common examples include contributions to a 401(k), health insurance premiums, or a savings bond program.

The beauty of this approach is that it takes the decision out of your hands. By automating the process, you consistently save without having to think about it, which makes it one of the most reliable ways to build long-term financial security.
