Deploy Your 15% for Retirement: Accounts, Order & Smart Funds

July 16, 20268 min read

You've done the hard work. You've tackled debt, built your emergency fund, and now you're standing at the precipice of true wealth building! This is where your money starts working for you in a big way. Welcome to Wealth Building Step 4: Invest 15% of your gross income into retirement.

This step can feel a little intimidating. "Investing" sounds complicated, full of jargon and endless choices. But here at Wealth by Design, we're going to break it down into simple, actionable steps. You don't need to be a financial guru to build a powerful retirement nest egg. You just need a clear plan, and that's exactly what we're giving you today.

We'll cover which accounts to use, the smart order to prioritize your investments, and simple fund choices that even a beginner can understand and manage. Let's get your 15% working!

Why 15%? The Power of Consistency

Before we dive into the "how," let's quickly reinforce the "why." 15% of your gross income (that's your income before taxes and deductions) is a powerful sweet spot. It's enough to leverage the miracle of compound interest over decades, without feeling overwhelming or feeling like your entire budget is being used up to save for retirement, allowing you to enjoy life now, as well.

Imagine this: you invest $600 a month for 30 years (from 35 to 65), earning an average 10% annual return (the historical stock market average). You'll have contributed $216,000 of your own money. But thanks to compounding, your nest egg could grow to well over $1 million! That's the power of starting early and being consistent. Your future self will thank you.

Demystifying Retirement Accounts

Think of retirement accounts as special "containers" for your investments. They offer incredible tax advantages that help your money grow faster. It's crucial to understand the two main types you'll likely encounter: employer-sponsored plans and Individual Retirement Arrangements (IRAs).

The 401(k) (or 403(b) / TSP)

Many employers offer a 401(k) plan (or a 403(b) for non-profits and schools, or a TSP for government employees). These are excellent vehicles for retirement savings.

  • Employer Match: This is the most exciting feature! Many companies will match a portion of what you contribute. It's literally free money for your retirement but requires you to fund your 401(k) for them to match your funding. Don't leave free monty on the table!
  • Contribution Limits: These accounts have high annual contribution limits, allowing you to save a lot.
  • Tax Benefits: Most 401(k)s allow pre-tax contributions, meaning your money goes in before income taxes are calculated. You pay taxes when you withdraw in retirement. Some employers also offer a Roth 401(k) option, where you pay taxes now and withdraw tax-free later.

The IRA (Individual Retirement Arrangement)

An IRA is a personal retirement account you open yourself, typically through a brokerage firm like Vanguard, Fidelity, or Charles Schwab.

  • Traditional IRA: Contributions are likely tax-deductible, reducing your taxable income now. You pay taxes when you withdraw in retirement.
  • Roth IRA: You contribute money you've already paid taxes on. The magic? Your money grows completely tax-free, and qualified withdrawals in retirement are also tax-free! This is often the preferred choice for most families, especially if you expect to be in a higher tax bracket in retirement.
  • Contribution Limits: IRAs have lower annual contribution limits than 401(k)s, but they offer more flexibility in investment choices.

Don't worry too much about the nitty-gritty tax rules right now. The key is knowing these accounts are your best friends for building wealth.

Your Prioritization Playbook: Where to Invest Your 15%

Now for the practical part: the specific order to deploy your 15%. This strategy ensures you maximize "free money" and tax benefits. Please note, if your employer does offer a matching fund, this match should not be included in your 15% retirement set-aside. Consider the match as a cherry on-top to increase your wealth for retirement.

Step 1: Contribute to Your 401(k) / 403(b) Up to the Full Employer Match

This is your absolute first priority. If your employer offers a match, you must contribute enough to get every penny of it. It's an instant return on your investment that you can't get anywhere else. If your employer offers a Roth 401(k) / 403(b) that can still receive the match, do this instead of a traditional 401(k) / 403(b), even if their match goes to the traditional account.

Example: Your gross income is $60,000 per year. Your company matches 100% of your contributions up to 5% of your salary. This means if you put $3,000 ($60,000 * 0.05) into your 401(k), your employer also puts in $3,000. That's $3,000 of free money every year! You've instantly doubled your initial investment.

Calculate what percentage of your income this "match" contribution represents. For our example, $3,000 is 5% of your gross income.

Step 2: Max Out Your Roth IRA

After securing your employer match, the next stop is usually a Roth IRA. Why a Roth? For most families, especially those just starting out or in their wealth-building years, the idea of tax-free growth and tax-free withdrawals in retirement is incredibly powerful. You're paying taxes on the seed, not on the harvest!

In 2026, the contribution limit for a Roth IRA is $7,500 (or $8,600 if you're 50 or older). If your income is above a certain level, you might not be eligible to contribute directly to a Roth IRA, but don't worry about that for now – most families can. And the good news? You can have both a Roth IRA and a Roth 401(k) / 403(b) account! The better news? You and your spouse can both have Roth IRA's, even if your spouse is a stay-at-home parent or not receiving a paycheck.

Contribute the maximum amount you can afford to your Roth IRA, up to the annual limit, until you reach 15% of your total gross income.

Step 3: Go Back to Your 401(k) / 403(b) Until You Hit 15% (if you haven't hit 15% already)

Once you've secured the employer match and maxed out your Roth IRA (if you can), it's time to return to your employer-sponsored plan to reach your 15% goal.

Let's use an example to tie it all together:

  • Gross Income: $80,000
  • 15% Goal: $12,000 per year ($80,000 * 0.15)
  • Employer 401(k) Match: Company matches 50% of your contributions up to 6% of your salary.
    • You contribute 6% of $80,000 = $4,800.
    • Your employer contributes 3% (50% of your 6%) of $80,000 = $2,400.
    • Total contributed to 401(k) so far: $4,800 (yours) + $2,400 (match) = $7,200.
  • Roth IRA: You open a Roth IRA and max it out at $7,500 (for 2026).
    • Your total personal contributions so far: $4,800 (401k) + $7,500 (Roth IRA) = $12,300.
  • Remaining to hit 15%: None. You've hit your 15% goal of $12,000 (and you've gotten a sweet $2,400 of free retirement money from your employer).
    • If you had not hit your 15%, you could direct the remaining money required to hit 15% back to your 401(k) or even a traditional IRA if you so choose.
  • Final Breakdown:
    • Your 401(k) contributions: $4,800 (for match)
    • Your Roth IRA contributions: $7,500
    • Total Personal Contributions: $12,300 (just over the 15% of $80,000)
    • Plus, don't forget the employer match of $2,400! Your total investment for the year is $14,700.

This strategy ensures you grab all available "free money" first, then maximize the tax-free growth of a Roth IRA, and finally fill up your 401(k) to hit your 15% target.

Smart Funds for Beginners: Keep it Simple and Low-Cost

You've got your accounts and your order. Now, what do you actually buy inside these accounts? Forget trying to pick individual stocks or time the market. For most people, especially beginners, the best approach is shockingly simple: low-cost growth stock Mutual Funds or Exchange Traded Funds (ETF's).

What are Mutual Funds and Exchange Traded Funds?

Think of these funds as a basket of investments. Instead of buying one company's stock, you buy a tiny piece of hundreds or even thousands of different companies all at once. This instantly diversifies your investment and reduces overall risk.

The Best Choices for You:

  1. Index Funds: These are a fantastic starting point. An index fund simply aims to track a specific market index, like the S&P 500 (the 500 largest U.S. companies). You're not paying a fund manager to try and beat the market; you're just getting the market's overall return, which has historically been excellent over the long term. Look for words like "S&P 500 Index Fund" or "Total Stock Market Index Fund."
  2. Growth Stock Mutual Funds: These funds invest in companies that are expected to grow at an above-average rate compared to other companies in the market. They are designed for long-term wealth building.
  3. Target-Date Funds (Good for hands-off approach): If you want a "set it and forget it" option, a target-date fund might be for you. You choose a fund with the year closest to when you plan to retire (e.g., "2055 Target Date Fund"). The fund automatically adjusts its asset allocation (more stocks when you're young, more bonds as you get older) to become more conservative as you approach retirement. They typically have slightly higher fees than pure index funds, but the convenience can be worth it for some.

Key Advice When Choosing Funds:

  • Look for Low Fees (Expense Ratio): This is critical! Fees eat into your returns. Aim for an expense ratio under 0.50%, and ideally under 0.20% for index funds. Vanguard, Fidelity, and Charles Schwab are known for their low-cost options.
  • Broad Market Exposure: Don't pick niche funds that focus on just one industry or sector unless you feel you know that sector well. You want funds that spread your money across many different companies and industries.
  • Long-Term Focus: Remember, you're investing for decades. Don't check your balances daily. Ride out the ups and downs of the market. When you consistently invest, what is known as dollar-cost averaging (i.e. you sometimes buy when funds are expensive sometimes buy when funds are inexpensive) will work in your benefit and yields will likely be greater than ever trying to time the market. When you buy into a fund, make sure it has a good historic trackprecord (usually they will show 1, 5 and 10 year growth).

When you log into your 401(k) or IRA account, you'll see a list of investment options. Don't be overwhelmed. Look for the phrases above and compare their expense ratios. If you're unsure, most providers offer educational resources or customer service to help you select appropriate funds. For example, Warren Buffett (one of the most reknowned investors of all time) has stated, "In my view, for most people, the best thing to do is to own the S&P 500 index fund." It's not supposed to be rocket-science, for example, you can Google "good Vanguard ETF's for retirement accounts" or similar to find some good up-front options.

The Power of Patience and Consistency

Investing isn't a get-rich-quick scheme; it's a get-rich-slow-and-steady plan. Your greatest allies are time and consistency. Keep that 15% going month after month, year after year, through market highs and lows. You're building a future that provides true financial security and freedom.

Frequently Asked Questions

Q: What if I can't afford 15% right now?

A: Start somewhere! Even if you can only do 5% or 10% initially, that's better than nothing. The most important thing is to get started and then gradually increase your contribution as your income grows and your budget allows. Keep chipping away at that 15% goal.

Q: Am I too old to start investing? I never knew about these accounts when I was youger.

A: No, you are not too old to begin investing! Age oftentimes, however, alters what we invest in. For example, for a younger person, they can accept more risk with their money since they have a longer amount of time to regain losses. For an older person, usually less risky investments (think bonds, dividend funds, etc.) may be a better choice. And don't worry about not knowing about investment accounts...take as an example: the first year that American's were even able to open a Roth IRA was 1998, so the account type is still very young!

Q: Should I invest in a Roth 401(k) or Traditional 401(k)?

A: If your employer offers a Roth 401(k) option, it's often a great choice, especially for younger investors who expect their income (and therefore tax bracket) to be higher in retirement. You pay taxes now and enjoy tax-free growth and withdrawals later. A Traditional 401(k) gives you a tax break now, but you pay taxes in retirement. If you're unsure, and you qualify, a Roth IRA is usually a clear winner for your personal IRA contributions due to its flexibility.

Q: Can I manage my investments myself, or do I need a financial advisor?

A: For basic retirement investing using low-cost index funds or target-date funds, you can absolutely manage it yourself. The strategy we've outlined is designed to be simple and effective without needing an expensive advisor. If your situation becomes more complex (e.g., you own a business, have significant assets outside retirement accounts, or want intricate estate planning), then a fee-only financial advisor can be a valuable resource.

Q: What about individual stocks? Should I invest in those?

A: For your core retirement savings, we strongly recommend against picking individual stocks. It's incredibly risky and requires a lot of research and time and will cause you additional unneeded stress. Stick to broad market index funds or growth stock mutual funds. You'll get better diversification, lower risk, and excellent long-term returns without the stress.

Q: What about my old 401(k) from a previous job?

A: You have a few options: you can leave it with your old employer (often not ideal due to limited choices or higher fees), roll it over into your current employer's 401(k) (if allowed), or roll it over into an IRA. Rolling it into an IRA (often a "rollover IRA") usually gives you the most control and access to low-cost investment options. Talk to your new 401(k) provider or a brokerage firm for guidance on this process.
