# What Is a Roth IRA? (Explained Like You're 17, Because I Am)

If you've spent any time on r/personalfinance or talked to literally any adult who's halfway decent with money, you've heard the same thing: "Open a Roth IRA as soon as you can." And then they don't explain what it actually is, or they explain it in a way that makes your eyes glaze over.

I'm 17. I had to figure this out on my own. So here's the version I would've wanted — no jargon, real examples, and I'll tell you exactly why people lose their minds over this account.

The simple version

A Roth IRA is a special type of investment account where you put in money you've already paid taxes on, and then everything it earns grows **tax-free forever**. When you pull the money out in retirement, you don't owe the government a single dollar on the growth. That's the whole thing. That's why people love it.

Let me show you why that matters with actual numbers.

Say you put $200/month into a Roth IRA starting at 18. At an average 7% annual return (adjusted for inflation), by age 60 you'd have roughly **$440,000**. You contributed about $100,800 of your own money over those years. The other ~$340,000 is pure growth.

In a regular investment account, you'd owe taxes on that $340,000 in growth when you sell — potentially 15-20% of it, which is $50,000-$68,000 going to the IRS. In a Roth IRA? You keep all of it. Every dollar. That's not a small difference, that's a new car or a year of your kid's college that you get to keep just because you picked the right account type at 18.

## Why it's especially broken for young people

The Roth IRA is basically designed to reward people who start early, and here's why.

You pay taxes on the money *going in*, not coming out. Right now, as a teenager or young adult, you're probably in the lowest tax bracket you'll ever be in. Maybe you're making $10,000-$20,000 a year from a part-time job. The taxes you're paying on that income are tiny.

But 30 years from now, you'll hopefully be making way more money and in a much higher tax bracket. If you had a traditional IRA (the other kind), you'd skip taxes now but pay them later — at that higher rate. With a Roth, you're locking in today's low tax rate and never paying taxes on the growth. It's like buying something on sale that only gets more expensive over time.

This is literally why every financial advisor tells young people to open a Roth IRA first. The math is overwhelmingly in your favor when you're young and not making a lot of money.

## How it actually works (the rules)

Here are the rules that matter. I'm skipping the obscure edge cases that don't apply to us.

**Who can open one?** Anyone with earned income (money from a job, not allowance or gifts). If you're under 18, your parent opens a custodial Roth IRA for you — the money is yours, they just manage it until you're 18 or 21 depending on your state.

**How much can you put in?** Up to $7,000 per year (as of 2024), but never more than you earned. So if you only made $4,000 this year, your max contribution is $4,000.

**When can you take money out?** Here's where it gets good:

- Your **contributions** (the money you put in) can be withdrawn anytime, for any reason, with no penalty. Read that again. You can always get your own money back. This makes the Roth IRA way less scary than people think — it's not locked away forever.

- The **growth** (the money your investments earned) should stay in until age 59½. If you pull growth out early, you'll usually pay taxes and a 10% penalty on it. But there are exceptions for things like buying your first home (up to $10,000 of growth, penalty-free).

Where do you open one?* Fidelity, Vanguard, or Schwab. All free, all good. I'd go with Fidelity because they have no minimums and their app is solid, but honestly it doesn't matter much. Pick one and move on.

**What do you invest in inside the Roth IRA?** This is the part that confuses people. A Roth IRA is not an investment itself — it's a container. You open the account, and then you buy investments inside of it. Most people buy index funds (like FXAIX or VTI), which I wrote about in my [index funds post]. If you do nothing after opening the account, your money just sits there as cash earning almost nothing. You have to actually buy something.

## "But I might need the money before retirement"

This is the biggest fear I hear from people my age, and it's mostly based on a misunderstanding.

Remember — you can withdraw your contributions anytime. If you put in $5,000 over two years and something comes up, you can pull that $5,000 back out with no penalty and no taxes. You only get penalized for pulling out the *growth* early.

So a Roth IRA is actually more flexible than most people think. It's not like your money disappears into a vault until you're 60. The growth is locked up (mostly), but your original contributions are always accessible. That makes it a surprisingly reasonable place to put money even if you're not 100% sure you won't need it.

That said, if you know you'll need the money within a year or two — for a car, for college expenses, for rent — keep that money in a savings account instead. The Roth IRA is for money you're reasonably confident you can leave alone for at least 5+ years.

Roth IRA vs 401(k) — which one first?

You'll hear about 401(k)s too, so let me clear this up fast.

A 401(k) is a retirement account you get through your employer. The big draw is that many employers will **match** your contributions — meaning if you put in 5% of your paycheck, they'll add another 5% for free. That's a 100% return on day one. You can't beat that.

So the order is:

1. **401(k) up to the employer match** — get the free money first, always

2. **Max out your Roth IRA** — $7,000/year of tax-free growth

3. **Back to the 401(k)** — if you still have money to invest, put more into the 401(k) beyond the match

If you don't have a job that offers a 401(k) (most part-time and student jobs don't), then the Roth IRA is your only move and it's a great one.

## The biggest mistake: opening the account and not investing

I need to emphasize this because it happens constantly.

People hear "open a Roth IRA," they go to Fidelity, they open the account, they deposit money, and then they stop. The money sits in the account as cash, earning basically nothing, and they think they're investing.

**Opening the account is step one. Buying an investment inside the account is step two.** You need both. Go into the account, search for a total market index fund (FXAIX at Fidelity is a common one), and buy it. Then set up automatic contributions so you're adding money regularly without thinking about it.

I've seen Reddit posts from people who had a Roth IRA for three years and didn't realize their money was just sitting in cash the whole time. Don't be that person.

## How to actually set one up (5 minutes)

It's genuinely this simple:

1. Go to Fidelity.com (or Vanguard or Schwab)

2. Click "Open an Account" and select Roth IRA (if you're under 18, look for "custodial Roth IRA" or have your parent open it)

3. Fill in your info, link your bank account

4. Deposit whatever you can — even $50 to start

5. Buy a total market index fund inside the account (like FXAIX or FZROX at Fidelity)

6. Set up automatic monthly contributions so it happens without you thinking about it

That's it. You're done. You now have a tax-free wealth-building machine running in the background while you go to school, hang out with friends, and do literally anything else. Future you is going to be very grateful.

## The bottom line

A Roth IRA is the single best account for young people to start investing in. You pay taxes now while they're low, your money grows tax-free for decades, and you can always pull your contributions back out if you need to. The only catch is you need earned income to contribute, and there's a $7,000/year cap.

If you're 18+ with any job income and you don't have a Roth IRA, go open one today. Not next week, not "when I have more money." Today, with whatever you've got. The amount doesn't matter nearly as much as the head start.

And if you're under 18 like me, talk to your parents about a custodial Roth IRA. Ten minutes of setup now could be worth six figures by the time you retire. That's not an exaggeration — it's just how the math works when you start this early.
