The 401(k) match, free money, explained

Free money is real, and it's at your job

Most "free money" promises are scams. This one isn't. It's called a 401(k) match, and if your job offers it and you're not taking it, you're literally leaving money on the table. Let's fix that.

What's a 401(k)?

A 401(k) is a retirement savings account you get through your job. Money goes in straight from your paycheck, and it gets invested to grow over many years for when you're older.

That's useful on its own. But the match is the part that's almost too good.

The match: your boss pays in too

Here's the deal. Many employers say: "For every dollar you put into your 401(k), we'll add a dollar too — up to a limit."

Read that again. They add their own money on top of yours. For free. Just for saving.

A common setup looks like this: the company matches 100% of what you put in, up to, say, 5% of your pay. So if you contribute 5% of your paycheck, they add another 5%. You saved 5%, but 10% landed in your account.

Why this is "doubling your money"

Think about what just happened. You put in $1. Instantly, it became $2. That's a 100% gain — before the money has even started growing.

There is no investment on earth that reliably doubles your money the second you put it in. Except this. The match is the closest thing to a guarantee you'll ever be handed.

Skip it, and you're turning down a raise. That's really what it is a raise you only get if you save.

A quick example

Say you earn $40,000 a year, and your job matches up to 5%.

• 5% of your pay is $2,000.
• You put in $2,000 from your paychecks over the year.
• Your employer drops in another $2,000, free.

You saved $2,000 and ended up with $4,000 working for your future. Every single year you do this.

Miss it, and that free $2,000 just... doesn't happen. Gone for good.

Two things to check

• What's the match? Ask HR or check your benefits site: "Do we have a 401(k) match, and how much?" Find the magic percentage they'll match up to. Try to contribute at least that much, that's the sweet spot where you grab every free dollar.
• "Vesting." Some companies make you stay a year or two before their matched money is fully yours to keep. It's not a trick, just a "stick around" rule. Worth knowing, but it shouldn't stop you from taking the match.

"But money's tight right now"

Fair. But even small counts. If you can't hit the full match yet, put in something. Then bump it up 1% whenever you get a raise, you'll barely feel it, and you'll inch toward grabbing the full free match.

Leaving the match on the table is the one money mistake that costs you guaranteed cash. Almost nothing else in finance is this clear-cut.

Start today

1. Ask: "Does my job offer a 401(k) match, and up to what percent?"
2. Set your contribution to at least that percent if you possibly can.
3. Check the vesting rule so you know when the match is fully yours.
4. Raise your contribution a little every time your pay goes up.

It's the rare deal with no catch: you save, and someone hands you the same amount for free. Take it.
