The day I sat across from a 24-year-old named Marcus, I saw something I’ll never forget.
He had just landed his first real job — $58,000 a year, a badge with his name on it, and a stack of HR onboarding paperwork he had absolutely no idea what to do with. He slid the benefits enrollment form across my desk, pointed to the retirement section, and said six words that changed how I approach every client conversation:
“I’ll just figure this out later.”
Marcus is 51 now. He finally has a Roth IRA. He wishes he’d opened it at 24.
This post is for every Marcus out there. Because “later” is the most expensive word in personal finance — and the decision between a 401(k) and a Roth IRA is one of the few financial choices where getting it right early compounds into something extraordinary.
Let’s break it down.
What This Post Covers
- What a 401(k) and Roth IRA actually are (in plain English)
- The key differences that matter for someone just starting out
- Which one to prioritize first — and why the order matters
- The strategy I’ve recommended to thousands of clients over 20 years
- Common mistakes first-timers make
First, Let’s Kill the Jargon
What Is a 401(k)?
A 401(k) is a retirement savings account offered through your employer. You contribute a percentage of your paycheck before taxes are taken out — meaning your taxable income goes down today.
Your employer may also match your contributions up to a certain percentage. That match is free money. Genuinely, actually free.
When you retire and withdraw the money, then you pay income taxes on it.
Quick math: You earn $60,000. You contribute 6% ($3,600) to your 401(k). The IRS only taxes you on $56,400 this year. You pay taxes later — but by then, hopefully at a lower rate in retirement.
What Is a Roth IRA?
A Roth IRA is a retirement account you open yourself, independent of your employer. You contribute money after taxes — so there’s no immediate tax break.
The magic? Your money grows completely tax-free. When you retire and pull it out, you pay zero taxes. None. Not a cent.
You also get more flexibility: you can withdraw your contributions (not earnings) at any time without penalty — something the 401(k) doesn’t offer.
2024 contribution limits:
- 401(k): up to $23,000/year ($30,500 if you’re 50+)
- Roth IRA: up to $7,000/year ($8,000 if you’re 50+)
Note: Roth IRA eligibility phases out at higher income levels — $146,000 for single filers and $230,000 for married filers in 2024.
The Real Question: Which One First?
Here’s the answer I’ve given for two decades, and I stand by it completely:
Step 1 — Capture the Full 401(k) Employer Match First
If your employer matches contributions, contribute enough to get every dollar of that match before you do anything else.
This is non-negotiable. Missing your employer match is the equivalent of turning down a 50–100% guaranteed return on your money before the market even opens. I’ve never met a hedge fund that can promise you that.
Example: Your employer matches 100% of contributions up to 4% of your salary. You earn $60,000. Contribute 4% ($2,400), and your employer adds another $2,400. You just turned $2,400 into $4,800 before earning a single dollar in investment returns.
If you stop here and put the rest in your couch cushions, you’ve still done something smart. But don’t stop here.
Step 2 — Open and Max Your Roth IRA
Once you’ve secured the full employer match, your next move is the Roth IRA — and this is where it gets personal.
Here’s why a Roth IRA is almost always the better second move for someone early in their career:
You’re probably in a lower tax bracket right now than you will be in 20 years.
Think about it. You’re just starting out. Your income is lower. Your tax rate is lower. This is precisely the moment to pay taxes now at today’s bargain rate, let the money grow for decades, and pull it out in retirement completely tax-free.
By the time you’re 65, decades of compounding could turn that $7,000 annual contribution into something that would genuinely shock you. And you won’t owe a single dollar in taxes on any of it.
Roth IRAs also offer something the 401(k) doesn’t: flexibility and control. You choose your investments. You’re not limited to whatever fund options your employer picked. And in a true emergency, you can withdraw your contributions without penalty — though I’d recommend treating this as a last resort.
Step 3 — Go Back and Max Your 401(k)
If you’ve maxed your Roth IRA ($7,000/year) and still have room to invest, go back to your 401(k) and contribute as much as you can, up to the annual limit.
Even without the match, the tax deferral is valuable — especially as your income grows and your tax rate climbs.
The Strategy, Simplified
| Priority | Action | Why |
|---|---|---|
| First | Contribute to 401(k) up to the employer match | Free money — always take it |
| Second | Max out Roth IRA ($7,000/year) | Tax-free growth when your tax rate is lowest |
| Third | Go back and max 401(k) ($23,000/year) | Additional tax-deferred growth |
| Fourth | Taxable brokerage account | After maxing tax-advantaged accounts |
Why This Order Matters So Much
Let me show you the compound effect with two fictional versions of the same person.
Alex and Jordan, both age 24, both earning $60,000:
- Alex gets the employer match, then opens a Roth IRA and contributes $500/month.
- Jordan says, “I’ll start saving seriously at 35.”
Assuming a 7% average annual return:
| Age | Alex’s Roth IRA Value | Jordan’s Roth IRA Value |
|---|---|---|
| 35 | ~$100,000 | $0 |
| 45 | ~$213,000 | ~$85,000 |
| 65 | ~$1,010,000 | ~$340,000 |
The 11-year head start is worth $670,000 — tax-free.
That’s not a typo. That’s the arithmetic of starting in your 20s.
The Mistakes I See Most Often
1. Skipping the 401(k) match to “invest elsewhere” There is no investment that guarantees a 50–100% instant return. Take the match. Always.
2. Waiting until they “earn more money” Even $50/month in a Roth IRA at 24 beats $500/month starting at 40. Time is the ingredient no amount of money can replace.
3. Being paralyzed by investment choice For most beginners: pick a target-date retirement fund (e.g., “Target Date 2060 Fund”) inside your 401(k) or Roth IRA. It automatically adjusts risk as you age. Done. You can optimize later as you learn more.
4. Cashing out a 401(k) when changing jobs I have watched people lose years of compounding because they cashed out a small 401(k) when they switched employers. Roll it over to an IRA or your new employer’s plan instead.
5. Thinking they make too much for a Roth IRA If your income exceeds the limits, look into the Backdoor Roth IRA strategy. It’s legal, widely used, and worth exploring with a financial advisor.
A Note on Income Limits (2024)
You can contribute the full $7,000 to a Roth IRA if your modified adjusted gross income (MAGI) is:
- Under $146,000 if you’re single
- Under $230,000 if you’re married filing jointly
Contributions phase out above those thresholds and are eliminated at $161,000 (single) and $240,000 (married). If you’re above the limit, consult a CFA about the backdoor Roth strategy.
The Conversation I Wish I’d Had at 24
No one sits you down when you get your first job and explains that a decision you make on a Tuesday afternoon during HR onboarding — while you’re still figuring out where the coffee machine is — will determine whether you retire comfortably or spend your 60s anxious about money.
No one tells you that the retirement account checkbox you almost skip is the single most powerful financial tool available to you.
I’m telling you now.
You don’t need to understand every nuance of tax law. You don’t need a finance degree. You need to do three things:
- Contribute enough to your 401(k) to capture the full employer match.
- Open a Roth IRA and automate a monthly contribution — even $100.
- Leave it alone and let time do the heavy lifting.
The best time to start was yesterday. The second best time is today, before you close this tab.
Frequently Asked Questions
Can I have both a 401(k) and a Roth IRA at the same time? Yes. Absolutely. That’s exactly the strategy outlined above.
What if my employer doesn’t offer a 401(k)? Go straight to the Roth IRA. Open one through Fidelity, Vanguard, or Schwab — it takes about 15 minutes online.
I’m 35 and haven’t started yet. Is it too late? No. The second best time to plant a tree is today. Starting at 35 and investing consistently still produces transformative outcomes by retirement age. Stop waiting.
Should I pay off student loans before investing? If the interest rate on your loans is above 7%, prioritize paying them down. If it’s below 7%, at minimum capture your full employer 401(k) match while paying down debt — the guaranteed return from the match typically beats the interest savings.
What’s the difference between a traditional IRA and a Roth IRA? A traditional IRA gives you a tax deduction now and you pay taxes on withdrawal. A Roth IRA gives you no deduction now but tax-free withdrawals later. For most young earners, the Roth wins.
The Bottom Line
401(k) up to the employer match → Roth IRA to the max → back to the 401(k).
That’s the sequence. That’s the strategy. That’s what I’ve told clients for 20 years, from the 22-year-old just starting their first job to the 40-year-old who wishes they’d known earlier.
The gap between a comfortable retirement and a stressful one often comes down to decisions made in the first five years of a career — not because the stakes were enormous, but because time is the one resource you can never buy back.
Start today. Automate it. Don’t touch it.
