Roth IRA explained: how to build wealth tax-free
An account where hundreds of thousands of dollars in growth is never taxed sounds like it must have a catch. It doesn't, and it isn't an advanced strategy — almost anyone can open one this afternoon.

This is part of a series on personal finance and investing — the foundation people build long before they start buying assets like real estate.
Everyone has heard "you've got to get a Roth IRA." Fewer people can explain why it beats the alternatives, or what actually happens to the money over thirty years.
What a Roth IRA is
A retirement account you open and fund yourself. You contribute money you've already paid tax on, it gets invested, and it grows.
The advantage arrives at the other end. Every dollar of growth comes out tax-free in retirement. You paid tax on the seed, never on the harvest.
You can contribute up to $7,500 a year. That figure is adjusted periodically, so check the current limit.
The part that never gets taxed
Save $500 a month for thirty years and you've contributed $180,000 of your own money.
That's a gain of somewhere between 300% and 500% on what you contributed — and none of it is taxed when you spend it.
The range reflects returns. The low end assumes around 8% annually, the high end closer to 10%. Markets don't deliver either on schedule, so treat both as illustrations rather than projections.
Do the same thing in a regular brokerage account and you pay tax on the gains. That difference, compounded across decades, is the entire argument.
Pay tax now or pay tax later
A traditional IRA works the opposite way, much like a 401(k): contributions are pre-tax, the money grows untaxed, and you pay ordinary income tax when you withdraw in retirement.
| Roth IRA | Traditional IRA | |
|---|---|---|
| Contributions | After tax | Pre-tax |
| Growth | Untaxed | Untaxed |
| Withdrawals in retirement | Tax-free | Taxed as ordinary income |
| Tax benefit timing | Later | Now |
| Required minimum distributions | None for the original owner | Yes |
Two reasons to prefer the Roth
You'll probably earn more later. Pay tax on the smaller amount now rather than the larger amount decades from now. Better to be taxed as someone earning $60,000 than as whoever you become.
Tax rates are unpredictable, and the direction seems obvious. Nobody knows what rates will be in thirty years, but as populations grow and government spending continues, higher seems the safer bet than lower. Locking in today's rate is a hedge.
Most people I talk to expect to be in a higher bracket later, which is why I see more people choosing Roth over traditional now.
That last row matters too. Traditional accounts force withdrawals starting at 73 whether you need the money or not — something covered in the 401(k) guide. A Roth has no such requirement for the original owner, so the money can keep compounding untouched.
A short history, and what it tells you
Roth IRAs started in 1998. If your parents never mentioned one, that's likely because it didn't exist for most of their working lives — I graduated in 1997, and mine started investing only after getting advice from a tax professional years later.
| Year | Annual contribution limit |
|---|---|
| 1998 | $2,000 |
| 2008 | $5,000 |
| 2026 | $7,500 |
The trend is upward and it keeps going. The arrangement suits everyone — the government collects tax now, people save more for their own retirement — so there's no obvious reason for it to reverse. By 2035 the limit may well be considerably higher.
The things the enthusiasm usually skips
There are income limits. Above a certain income, you can't contribute directly to a Roth IRA at all, and there's a phase-out range below that where you can contribute only partially. The thresholds change each year. If you're a high earner, check where you stand before assuming this is available — there are other routes, but they need a conversation with a CPA rather than a video.
Tax-free isn't automatic. To withdraw earnings tax-free you generally need to be 59½ and the account must have been open at least five years. Your own contributions can be withdrawn at any time, but the growth has conditions attached.
Neither of these makes the account less worth having. They're just the sort of detail that's better learned now than at withdrawal.
Don't overcomplicate the investing
An account is just a container. What you hold inside it determines whether you land at the $750,000 end or somewhere well below it.
You don't need to pick stocks or become an analyst. Index funds are the straightforward approach — VOO tracks the S&P 500, so you own a slice of the largest companies in the country at once.
The mechanism people miss: index funds rebalance themselves. As companies fall out of the top 500 and new ones enter, the fund reallocates automatically. You're not managing it, and you're not betting on any single company surviving.
QQQ is the other one that comes up often — more technology-weighted, holding names like Apple, Google and Tesla.
None of this makes you a millionaire overnight. Done consistently for twenty or thirty years, it's how ordinary people get there.
Automate the deposits. Consistency beats timing, and nobody can reliably predict which year is the good one. Automating removes the decision entirely.
Why time matters more than amount
Earning 8% on $10,000 is $800. Not life-changing. Earning 8% on $100,000 is $8,000 — same percentage, entirely different outcome.
That's compounding: the returns start generating returns. The longer the runway, the more of the work it does for you.
Which is why starting at 25 rather than 35 matters more than contributing more later. You can't buy back time.
The pension isn't coming
Retirement used to involve one. Twenty years with a company doesn't produce one now, and they're disappearing quickly.
More people are self-employed than ever, myself included. If you're self-employed, the pension is you paying yourself — there's nobody else setting money aside on your behalf. A SEP IRA is worth looking at alongside a Roth in that situation.
Where to open one
Almost any established investment brokerage. Mine is with Vanguard, initially because it held a rollover from a previous employer, and I kept it there after looking into them — well established and trusted.
The provider matters far less than starting. Pick somewhere credible with an interface you'll actually use.
Start small, stay consistent, build the habit. Grow the contribution until you're maxing it out, then max it out every year for the rest of your working life.
Most millionaires aren't made by a shortcut. They're made by long-term decisions repeated consistently. Simple investments routinely outperform complicated ones, largely because people stick with them.
Roth IRA FAQ
What is a Roth IRA and how does it work?
A retirement account you open and fund yourself with money you've already paid tax on. The money is invested and grows, and qualified withdrawals in retirement — including all the growth — are entirely tax-free. You pay tax on what goes in and never on what it becomes.
How much can you contribute to a Roth IRA?
Up to $7,500 a year as of 2026. The limit has risen steadily since Roth IRAs began in 1998 at $2,000, reaching $5,000 by 2008. It's adjusted periodically, so confirm the current figure. There are also income limits above which you cannot contribute directly, and those change annually too.
Roth IRA or traditional IRA — which is better?
It depends on whether you expect to pay more tax now or later. A traditional IRA gives you the deduction today and taxes withdrawals in retirement; a Roth taxes the contribution now and nothing afterward. Most people expect to earn more later and expect tax rates to rise, which favours the Roth. A Roth also has no required minimum distributions for the original owner, while traditional accounts force withdrawals starting at 73.
How much will a Roth IRA be worth?
Contributing $500 a month for thirty years puts in $180,000 of your own money. Invested at roughly 8% to 10% annually, that grows to somewhere between $750,000 and $1.2 million — a gain of 300% to 500%, none of which is taxed on qualified withdrawal. Returns vary and fees reduce them, so treat these as illustrations.
What should I invest my Roth IRA in?
The account is just a container; what you hold in it determines the outcome. Broad index funds are the straightforward approach — VOO tracks the S&P 500, giving exposure to the largest US companies at once, and rebalances automatically as companies enter and leave the index. QQQ is a more technology-weighted alternative. Automating contributions removes the temptation to time the market.
When can I withdraw from a Roth IRA tax-free?
Generally once you're 59½ and the account has been open at least five years. Your own contributions can be withdrawn at any time without penalty, but the earnings carry those conditions. This differs from a traditional IRA, where all withdrawals are taxed as ordinary income.
