Definition

An employer-sponsored defined contribution retirement plan that employees can contribute to and employers may also make matching contributions. 401-K contributions are taxed when withdrawn.


Summary

A 401(k) is a workplace retirement savings account that allows employees to automatically save money from their paychecks before taxes are taken out. Think of it as a special savings account where your employer helps you save for retirement - many employers will even match some of your contributions (free money!). The money grows tax-free while it's in the account, but you'll pay taxes when you withdraw it in retirement. It's called a 'defined contribution' plan because you decide how much to contribute, unlike older pension plans where the employer promised a specific payout.

Usage Context

Essential for understanding retirement planning, employee benefits, tax-advantaged investing, and personal financial planning strategies. Critical when discussing long-term wealth building and comparing different retirement savings vehicles.

Common Confusions

  • Thinking you can withdraw money anytime without penalties (10% penalty before age 59½)
  • Confusing 401(k) with pension plans - 401(k) puts investment risk on employee
  • Not understanding that contributions reduce current taxable income but are taxed in retirement
  • Assuming all employer matches vest immediately (some have waiting periods)
  • Mixing up traditional 401(k) vs Roth 401(k) tax treatment
