You’ve paid off your debt, built an emergency fund, and now it’s time to start building wealth for your future. That’s what Step 4 is all about: investing 15% of your income for retirement.
💡 Why Start Now? Because Time Is Your Superpower
If you’re in your 20s or 30s, this step might feel like it can wait. But here’s the truth: the earlier you start, the easier it is to retire comfortably. That’s because of something called compound interest.
Let’s break it down.
👉 If you invest just $100/month into an S&P 500 index fund, and it averages a 10% annual return (a realistic long-term average), you could have over $1 million by age 65—just from investing what amounts to a cell phone bill.
Start later, and you’ll have to invest a lot more to catch up. The key is time in the market, not timing the market.
📈 Why the S&P 500? It’s a Bet on America
The S&P 500 includes 500 of the largest companies in the U.S.—household names like Apple, Microsoft, Google, and Amazon. Investing in a low-cost index fund that tracks the S&P 500 gives you instant diversification and a slice of the overall U.S. economy.
Historically, this index has returned about 10% per year on average. And yes, there are ups and downs—but over the long term, the trend is up.
That’s why I built a 10-Year Avg. Annual Return tracker into our tools: to show you that despite market noise and headlines, long-term investors win by staying the course.
Don’t let emotions run the show. Logic tells us that long-term investing in the broad market beats short-term panic.
🚀 How to Start Investing (Without Getting Overwhelmed)
Ready to start? Here’s how:
- Start with your 401(k) (or similar employer plan):
- If your job offers a matching contribution, invest at least enough to get the full match. That’s free money. Don’t leave it on the table.
- Open an IRA:
- If you don’t have a workplace plan or want to invest more, open a Roth IRA or Traditional IRA. Here’s a quick comparison:
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| Contributions | Pre-tax (may reduce your tax bill now) | Post-tax (no tax break now) |
| Withdrawals in Retirement | Taxable | Tax-free (if rules are followed) |
| Income Limits | No income limit to contribute | Income limits apply |
| Best for… | People who want tax savings now | People who want tax-free income later |
For younger investors who expect to earn more in the future, a Roth IRA is often a great choice.
- Use low-cost index funds:
- Choose broad-market index funds like one that tracks the S&P 500.
- Many brokers offer automatic investing and even apps to make this super simple.
🧠 Why Retirement Feels So Far Away (and Why You Should Care Anyway)
If you’re young, retirement might seem abstract—like something for future you to worry about. Psychologists call this “future-self disconnect.” Basically, you don’t feel connected to the older version of yourself, so you don’t prioritize that person’s needs.
But think of it this way:
- Future you will still need a place to live.
- Future you will still have bills to pay.
- Future you might not want (or be able) to work forever.
Every dollar you invest now is a gift to your future self—so that one day you can live with freedom, not fear.
😬 What If You’re Behind?
If you’re closer to retirement and don’t have much saved, you’re not out of luck—but it’s time to act with urgency.
Here’s what to do:
- Start investing immediately—even if it’s more than 15% of your income.
- Eliminate debt so you can redirect that money toward your future.
- Max out contributions to IRAs and 401(k)s (especially if you’re 50+, which allows for catch-up contributions).
- Consider delaying retirement if you’re healthy—each year of working can mean thousands more in savings and possibly higher Social Security benefits.
- Downsize expenses and look for part-time work if needed to stretch your income.
