The 401k: The One That Comes Through Work
Okay. New module. We spent the last one on the match specifically, so now let's back up and talk about the 401k itself, because I've been throwing that word around like everyone already knows what it is.
Here's the thing. A 401k is just a retirement account your employer sets up so you can put money in before it hits your paycheck. That's it. That's the whole magic trick. The money comes out of your check before taxes touch it, goes into an account with your name on it, and sits there growing until you're old enough to use it without a penalty.
The "before taxes" part matters, so let's slow down there.
Traditional vs. Roth, at the level that matters right now
Most work plans offer traditional 401k money, and some offer a Roth 401k option too. Traditional means the money goes in before taxes are taken out, which lowers your taxable income now, but you'll pay taxes when you take it out in retirement. Roth 401k means you pay the taxes now, and it comes out tax-free later.
I'm a bookkeeper, not an advisor, and I'm not going to tell you which one wins for your situation, because it depends on things like what tax bracket you're in now versus what you think you'll be in later, and nobody actually knows the future tax code. If your plan offers both and you're not sure, traditional is the safe default for most beginners, mostly because it's the one every plan has. We'll talk more about Roth accounts specifically in the next module.
What actually happens to your money
Once it's in the account, it doesn't just sit in cash. You pick investments, usually a short list of mutual funds with names that mean nothing to a normal human — something like "Target Date 2055 Fund" or "Growth and Income Fund." We're going to get into fund menus in a later lesson, so don't panic on that part today. For now I just want you to know the money isn't parked doing nothing. It's invested, which means it can go up and it can go down, and over a long stretch of years it has historically trended up. Historically. Not guaranteed. I won't tell you it's guaranteed because it isn't.
The steps, at home, tonight
- Find your plan's website or portal. You should have logged into this back in an earlier lesson. If you haven't yet, that's step zero.
- Look for "contribution percentage" or "elective deferral." That's the dial you control. It's usually shown as a percentage of your paycheck, not a dollar amount.
- Look for "investment elections" or "fund lineup." Don't change anything today. Just find where it lives so it's not a mystery next time we talk about it.
- Check whether you have a traditional bucket, a Roth bucket, or both showing on your balance page. Some people have money in both without realizing it, especially if they've changed jobs.
- Write down, in your ledger, the current balance and today's date. Just one line. We're building a habit of checking in, not panicking in real time.
A word about fees, and about caring too much or too little
Every 401k charges fees somewhere — an administrative fee, fund expense ratios, sometimes a small per-transaction charge. Fees matter more than people think and less than the internet screams about. A high fee is worth noticing and asking about. But I've seen people spend an hour arguing with themselves over a tenth of a percentage point in fees while contributing nothing at all to the account. That's missing the point. Get the money in first. Sweat the fee details later, and we will, in a few lessons.
Which reminds me. I once spent two hours on the phone with a bank getting a $12 duplicate fee reversed. Aaron said it wasn't worth my time for twelve dollars. I told him it wasn't about the twelve dollars, it was about the principle of the thing, and I still think I was right. But notice what I didn't do. I didn't spend two hours arguing about a 0.05% difference in fund expenses while my contribution sat at zero. Fight the small unfair thing when it's actually wrong. Don't let fee-hunting become a reason to stall on the bigger decision.
One caution, plainly
Don't touch this money early if you can help it. Taking a 401k loan or an early withdrawal usually comes with penalties and taxes that eat a real chunk of what you pull out, and it can mess with your ability to contribute for a while after. There are exceptions for real hardship, and if you're facing one, that's a conversation with your plan administrator, not something to guess your way through. For everyone else, treat this account like it's not there. Out of sight, growing quietly.
Before next time
Find where your fund lineup and your fee disclosure live in your account, even if the names mean nothing to you yet. We'll read one together next lesson. 💛
