What is a 401(k) plan primarily designed for?

A 401(k) plan is primarily designed to facilitate employer-sponsored retirement savings. This type of plan allows employees to contribute a portion of their pre-tax income to an investment account specifically for retirement. The contributions made to the account often come with tax advantages, as the funds can grow tax-deferred until withdrawal during retirement, at which point they are taxed as regular income.

Employers may also contribute to employees' 401(k) plans, typically by matching a certain percentage of employee contributions, which further encourages saving for retirement. This structured way of saving helps individuals build a financial nest egg to support themselves after they retire, making it a critical component of retirement planning.

In contrast, other options like providing health insurance benefits, funding educational expenses, or offering short-term loans do not align with the primary purpose of a 401(k) plan, as they serve different financial needs and goals.
