A 401(k) is a retirement savings account offered by your employer that lets you set aside money from each paycheck before it’s deposited into your checking account. The real power? Many employers match a portion of what you contribute—essentially free money for your future.

Your contributions grow tax-deferred, meaning you won't pay taxes on that money until you withdraw it in retirement. It's one of the most accessible ways to build long-term wealth, especially when you start early and let compound growth work in your favor. Think of it as paying your future self first, with a tax break today.
