401(k), Explained Simply

A 401(k) is a retirement savings account you get through your job, where money comes out of your paycheck before you ever see it and grows for decades.

Here is the plain version. Your employer sets up the account. You choose a percentage of each paycheck to send into it, and that money gets invested, usually in a mix of stock and bond funds. Because the money is pulled out automatically, you tend to not miss it, and that is the whole trick. Saving happens before spending gets a vote.

Why does this matter to a normal person? Two reasons. First, in a traditional 401(k) the money goes in before taxes, so you lower your tax bill today. Second, lots of employers add free money on top of what you put in (that is the match, and it is a big deal). Over a working life, a 401(k) is often the single biggest pile of money a regular person ever builds.

Here is a concrete example. Say you earn $50,000 and put in 6 percent, which is $3,000 a year, or about $125 per paycheck if you are paid twice a month. Invest that every year for 30 years at a 7 percent average return and you land somewhere near $300,000, and you only actually contributed $90,000 of it. The rest is growth. Start at 25 instead of 35 and that number can nearly double, because time is doing the heavy lifting.

Bottom line: A 401(k) is the easiest way most working people have to build real long-term money, because it is automatic, it can cut your taxes, and it often comes with free employer money attached. If your job offers one, it is worth understanding before you need it.
