How to Invest for Your Kids (The Simple Three-Account System That Actually Works)
One of the most common questions I get from parents is some version of this: "How should I be investing for my kids?"
And I get why it is confusing. There are 529 plans, UTMAs, UGMAs, custodial accounts, ESAs, and a dozen other account types floating around. None of them come with a clear explanation of which ones you actually need and which ones you can ignore.
So let me cut through the noise.
We use a three-account system for our own family. It is simple, it is intentional, and it covers every major financial goal you have for your kids without overcomplicating anything.
Here is exactly how it works.
Account One: A 529 for Education
A 529 is a tax-advantaged account built specifically for education expenses. The money grows tax-free, and withdrawals are tax-free as long as they go toward qualified education costs.
To put some real numbers on it: if you put $300 a month into a 529 starting at birth, at an average 8% return, you would have around $130,000 by the time your child turns 18. That is enough to cover a large portion of a four-year in-state public university.
That is not a guarantee, but it is a meaningful head start. And starting earlier matters more than starting with a large amount. Even $50 or $100 a month compounding over 18 years adds up significantly.
The 529 is your foundation. It handles the education side so that when your kid is 18, they are not starting their adult life buried in student loan debt.
Coach's Tip: Many states offer a tax deduction for contributions to their own state's 529 plan. Check your state's rules before opening one. In some cases, the in-state plan is the clear winner. In others, a plan from another state might offer better investment options.
Account Two: A Brokerage Account in Your Name, Not Theirs
This is where a lot of parents make a mistake they do not realize until it is too late.
The default advice you will often hear is to open a custodial account, specifically a UTMA, in your child's name. The problem is that when your child turns 18, that account becomes legally theirs. Completely. You have zero control over it. Even if they want to blow the entire thing in a weekend, there is nothing you can do about it.
I do not want $100,000 sitting in an account that an 18-year-old has full legal access to with no strings attached. That is not pessimism. That is just being realistic about how 18-year-olds think.
So instead, open a regular taxable brokerage account in your own name.
You invest whatever amount makes sense for your situation. You can build this up alongside the 529, or focus on it once you have hit a comfortable contribution level for education savings. Either approach works.
When the time comes to transfer it, you can do so on your terms. A down payment on a house. Seed money for a business. A wedding. Graduate school. Whatever the right move looks like at that point in their life. The key is that you get to make that judgment call rather than hoping for the best from a teenager with a sudden windfall.
Account Three: A Roth IRA If Your Child Has Earned Income
This one is powerful, and most parents do not even know it is an option.
If your child has earned income, they can have a Roth IRA. The money grows tax-free and comes out tax-free in retirement. For a child, that means potentially 50 or 60 years of tax-free compounding before they ever touch it.
I know the first question people ask: "Can I pay my kid to do chores and then put that money in a Roth IRA?" No. The IRS does not consider household chores to be earned income. Taking out the trash and doing dishes does not count.
But real, legitimate work does. If your child is old enough to mow lawns, shovel snow, referee youth sports, lifeguard, or work at a restaurant, that income qualifies. Any W-2 or 1099 income works. And if you run a business or side hustle, there may be legitimate ways to involve your children based on their age and what the actual work is.
Starting a Roth IRA even with a few hundred dollars a year when your child is young is one of the most powerful financial gifts you can give them.
Quick Win: If your teenager has a summer job this year, help them open a custodial Roth IRA. You can contribute up to the amount they actually earned, up to the annual IRA limit. Even a few years of contributions during their teens can compound into a significant retirement head start.
What This System Adds Up To Over Time
Here is the part that makes this feel real.
Every $1,000 invested at birth has the potential to grow to somewhere between $100,000 and $150,000 by retirement age, depending on long-term market returns. That is not a typo.
If you invest $100 a month from the day your child is born, you could have $45,000 to $50,000 by the time they turn 18. If that money stays invested and continues compounding until their mid-60s, it could grow to over $1 million.
That is less than what most families spend on toys, gadgets, and things that end up in a closet within six months.
You do not need generational wealth to build generational wealth. You just need to start early and stay consistent. The best time to set this up was when your kids were born. The second best time is this week.
The Simple Summary
You do not need to understand every account type that exists. You need three things working together:
A 529 to handle education costs and take the pressure off your child's adult life before it even starts.
A taxable brokerage in your name to build flexible wealth you can transfer on your terms when the time is right.
A Roth IRA for your child if they have earned income, so they can start compounding decades before most people even think about retirement.
That is the system. It is not complicated. It just requires starting.
