Dear 1PG: I Have a 401(k)… Now What?

A Beginner’s Guide to 401(k) Investing for Wealth

So you’ve joined your company’s 401(k) plan or opened an IRA—congratulations! That’s a major step toward building financial peace. But once it’s open, many people freeze.
What next? How do you actually make your money grow?

Let’s walk through it together, one practical step at a time.

Step 1: Decide How Much to Contribute

Your employer may automatically start you at 3%, but you can (and should) change that.
If your employer matches contributions—say, up to 5% of your salary—try to contribute at least that much. It’s literally free money.

💡 Practical Gal Tip:
Set a reminder to bump your contribution by 1% each year until you reach at least 10–15%. You’ll barely feel the difference, but your future self will.

(2025 limit: $23,000 for employees under 50; $30,500 if 50 or older.)

Step 2: Choose Traditional vs. Roth 401(k)

You’ll usually choose between:

• Traditional 401(k): You contribute pre-tax dollars now and pay taxes later when you withdraw.
• Roth 401(k): You pay taxes now, but your withdrawals are tax-free in retirement.

If you’re early in your career and expect higher earnings later, the Roth option often makes sense. But if you need the immediate tax break, go traditional.
And don’t worry—you can change your election mid-year if your plan allows.

Step 3: Pick Your Investments

This is where most people get stuck. Your 401(k) is not a savings account—it’s an investment account, and you need to tell it where to invest.

Common choices:

• Target-date funds: Adjust automatically as you near retirement. Great if you prefer a set-it-and-forget-it approach.
• Index funds: Low fees, broad diversification, and performance that mirrors the overall market.
• Bond funds: Less risky, but lower long-term returns.

📌 Practical Gal Tip:
If you’re overwhelmed, start with a target-date index fund that matches your expected retirement year (for example, 2060 Fund).

Step 4: Know Your Risk Tolerance

Investing risk feels scary—until you understand inflation is a risk too.

Ten years ago, a latte cost $3.65. Today it’s about $4.45.
That’s 22% inflation eating into your money’s value.

The stock market, though bumpy, has historically returned around 7–10% per year. Investing $5,000 today at 7% could grow to over $38,000 in 30 years.
Short-term dips happen and past performance is not a guarantee of future results.  

Most financial advisors will tell you staying invested through the ups and downs is how you win long-term.

Step 5: Watch the Fees

Every fund charges something to operate—called the expense ratio.
Lower is better. Look for funds with fees under 1% (ideally 0.10%–0.50%).

Ask your HR team where to find your plan’s fee disclosure statement or look in the “fund fact sheet” within your online account.

Step 6: Diversify and Review Annually

Spread your investments across different types—stocks, bonds, and cash equivalents—so you’re not tied to one outcome.
Then set a simple annual check-in:
✅ Confirm your contribution rate.
✅ Review performance (don’t obsess monthly).
✅ Rebalance if one fund has grown far larger than the rest.

Remember, wealth builds through consistency, not constant tinkering.

Step 7: Keep Learning as You Keep Investing

Building wealth isn’t just about adding money—it’s about adding knowledge.
Your 401(k) will grow faster and stronger when you grow more informed.

When you first start, you may just want to capture the employer match and pick a target-date fund—and that’s perfectly fine. But as your balance grows, so should your understanding.

Here’s how to keep learning without overwhelm:

• Read one article or book chapter a month on investing basics, diversification, or behavioral finance. (1Practical Gal recommends The Simple Path to Wealth or The Psychology of Money to start.)
• Learn about diversification—how owning a mix of U.S. and international stocks, bonds, and even real estate funds can balance risk.
• Understand what you own. Once a year, peek under the hood of your funds. What percentage is stocks vs. bonds? Domestic vs. international? Large companies vs. small?

💡 Practical Gal Tip:
Just like you increase your 401(k) contribution a little each year, increase your financial knowledge a little each year, too. The compound effect of learning pays the best dividends of all.
