Week 2: How a 14-Year-Old Becomes a Millionaire (And Almost Nobody Talks About It)

Last week we talked about what to do with your first paycheck. Save, spend, give. Build the habit. Pick the goal. If you missed that one, go read it before this one — what we're about to talk about builds directly on top of it.

Now we're going to take it to a level most kids your age never even hear about.

There's an account you can open right now, at your age, that almost no kid has and almost no parent talks about. It's called a Roth IRA. And what it does, mathematically, when you open it at 14 or 15 instead of 25, is so absurd that when you see the numbers, you're going to think someone made them up.

Stay with me. This one matters.

What a Roth IRA Actually Is (Without the Jargon)

Let me explain it without the jargon, because the jargon is what makes most people tune out before they understand it.

A Roth IRA is a special kind of savings account. It's not a regular savings account — the money inside it doesn't just sit there earning a tiny bit of interest. The money inside it gets invested. That means it grows. It grows because the companies you own pieces of through the account grow, and those companies make profits, and those profits come back to you.

Here's the part that matters. The growth inside a Roth IRA is never taxed. Ever. If you put $1,000 in this account at 14 and it becomes $50,000 by the time you're 65, you take out all $50,000 tax-free. The government doesn't get a cut. That's the deal.

Almost no other account works like this. Most accounts get taxed on the way in, or the way out, or somewhere in the middle. This one — if you follow the rules and leave the money alone until retirement — is yours. All of it.

The catch is that you can only put money into a Roth IRA if you have earned income. Allowance doesn't count. Birthday money doesn't count. Money your grandma sends you doesn't count. But the paycheck from your summer job? That counts. Babysitting money you reported? That counts. Mowing lawns and keeping records? That counts.

That's why this matters at your age and not before. You have something most younger kids don't — earned income. And earned income is the key that unlocks this account.

The Math That Should Not Be Legal

Now I'm going to show you the math. And I want you to actually sit with these numbers, because they're the entire point.

Let's say you put $1,000 into a Roth IRA at age 14. Just $1,000. One time. You never add another dollar. You invest it in a basic index fund — a fund that owns a small piece of basically every big company in America — and you leave it alone.

By the time you're 65, that $1,000 turns into somewhere around $50,000. From doing nothing. From letting time and the stock market do the work.

Now let's say instead of $1,000 once, you put $1,000 in every year from age 14 to age 22. Nine years of contributions, $9,000 total. Then you stop. You never put another dollar in. You let it sit for the next forty-something years.

By 65, you have somewhere around $400,000.

And here's the part that's going to make you mad. If you skip all of that — if you wait until you're 25 and you start contributing $1,000 a year and you do it every single year until you're 65, putting in $40,000 of your own money over 40 years — you end up with less than the kid who put in $9,000 between ages 14 and 22 and then stopped.

Less. With more than four times the contributions.

That's not a typo. That's compound interest. That's what time does. The earlier you start, the more time the money has to grow on top of itself. A dollar invested at 14 is worth way more than a dollar invested at 24, which is worth way more than a dollar invested at 34. The math doesn't care how hard you work later. It only cares when you started.

You have the one thing nobody can buy at any price. You have time. You have more time than the 35-year-old who finally has the income to invest. You have more time than the 45-year-old panicking about retirement. You have time, and you're allowed to use it right now.

How to Actually Open One (It's Easier Than You Think)

Here's the practical part. You can't open a Roth IRA by yourself if you're under 18 — you have to open a custodial Roth IRA, which means your parent or guardian has to set it up with you. They sign the paperwork. The account is in your name with them listed as the custodian. When you turn 18 (or 21 in some states), the account becomes fully yours.

The good news is, opening one is easier than most adults think. You go to a place like Fidelity or Charles Schwab or Vanguard — these are the big names, and they all offer custodial Roth IRAs with no minimum and no fees to open. You fill out an application online. Your parent provides their info and yours. The account is open in a few business days.

The slightly less fun part is that you have to prove your earned income, especially if you ever get audited. That means keeping records. If you have a W-2 job, the W-2 is your proof. If you're self-employed — babysitting, lawn care, dog walking, anything where you get paid in cash or Venmo — you need to keep a log. Date, amount, who paid you, what for. It's not complicated, but it has to exist. Without it, the IRS doesn't know you earned what you say you earned.

For this year, you can contribute up to $7,000 to a Roth IRA, or up to the amount of your earned income, whichever is lower. So if you earned $2,500 this summer, you can put in up to $2,500. Not all of it. Just whatever you can spare after the save-spend-give framework we talked about last week.

What to Buy Once the Account Is Open

This is where most people freeze up. They open the account, put money in, and then have no idea what to do next. The money just sits there in cash, not growing, not doing the magic thing we just talked about.

For someone your age, the answer is almost always the same. Buy a total stock market index fund or a target date retirement fund. Both of these are basically baskets that hold pieces of hundreds or thousands of companies at once. They're not exciting. They're not going to make you rich overnight. They're going to do exactly what we talked about — quietly grow, year after year, while you live your life.

Names to look up: VTI, VTSAX, FZROX, FXAIX. Or any target date fund with a year around 2070 or 2075. Your parent can help you pick. The brokerage can help you pick. But the boring answer is almost always the right answer.

Then the most important step. Leave it alone. Don't log in every day to check the balance. Don't panic when the market drops. Don't try to be clever. The kid who opens the account at 14 and doesn't touch it until retirement crushes the adult who's constantly buying and selling. The whole point is time, not effort.

Your Move This Week

If you have earned income from this summer, the move is to open a custodial Roth IRA in the next few weeks, before you forget. Sit down with your parent. Pick a brokerage. Fill out the application. Pick an index fund. Put in whatever you can — even $50 to start. Then keep adding from each paycheck through the rest of the summer.

If you don't have earned income yet, get some. Mow a lawn. Babysit. Walk dogs. Do something where you can document the income legitimately. Even a few hundred dollars contributed at your age is worth thousands by the time you retire.

And once the account is open, do the one thing almost no adult is disciplined enough to do — forget about it. Let time do the work. That's the whole job.

For the Parent or Guardian Reading This

If you're the parent, this is one of the most valuable financial moves you can make for your child, and it costs you nothing but a Saturday morning and a willingness to fill out forms.

A few things to handle on your end. Make sure your child's earned income is documented in a way that holds up — W-2 if they have a real job, a written record if they're self-employed. If they're working for your business and you're paying them legitimately for legitimate work, that counts too, and it comes with tax benefits on your side as well — worth a separate conversation with a planner who actually understands the play.

Consider matching your child's contribution. If they put in $500 of their own earned income, you put in $500. They can only contribute up to the amount they earned, but the matched dollars can come from anywhere as long as the total stays within the limit. This turns a $500 sacrifice into a $1,000 contribution, and it teaches them that saving has a reward — the same lesson the 401(k) match will reinforce in fifteen years.

And use this as the moment to have the conversation that almost no parent has with a teenager. The conversation about time being the most valuable thing they have. The conversation about compounding. The conversation about why every adult you know who is panicking about retirement is panicking because they didn't do this. Your kid is in the rare position of being able to do it on purpose, with intention, while it costs them almost nothing.

This Is How Generational Wealth Actually Starts

Look. The kid who opens a Roth IRA at 14 and contributes consistently through their teens and twenties is on a different financial track than 99 percent of the country by the time they're 30. Not because they're smarter. Not because they make more money. Because they started early and they didn't quit.

That's it. That's the whole secret. Start now. Don't quit.

If you're a parent reading this and you want to build a real plan that doesn't just give your kids money but gives them the framework to use it well — that's the work we do. Schedule a Power Hour with Black Mammoth.

Next week we shift to the high schoolers. We're going to talk about college, and specifically about the lie of the sticker price. If you have a kid who's a junior or senior, do not miss it.
