Should You Invest While You're in Debt? Investing Myths That Keep People Stuck

Key Takeaways

• If you're carrying high-interest credit card debt while investing in the stock market, you're likely losing money on a net basis. Paying off credit card debt at 22% APR is the equivalent of earning a guaranteed 22% return on your money — something the stock market has never consistently delivered. The myths that you need "big money" to invest, that the market is gambling, or that you've missed your window are all real misconceptions, but the biggest investing myth for people in debt is that investing should come before debt elimination.

There's a fascinating tension in the personal finance world between two pieces of advice that seem equally urgent. On one side, you have the investment community telling you that time in the market is everything, compound interest is the eighth wonder of the world, and every day you're not invested is a day of potential returns you'll never get back. On the other side, you have the debt management community telling you that carrying high-interest credit card debt is a financial emergency and that every dollar of interest you pay is a dollar you'll never see again. Both of these perspectives are correct. The problem is that for millions of Americans carrying credit card debt, they're being asked to follow both paths simultaneously — and the math doesn't support that.

At The Debt Relief Company, we sit squarely at the intersection of these two realities every day. Our clients are smart, motivated people who want to build wealth. Many of them are investing through their 401(k), contributing to a Roth IRA, or trading individual stocks through an app on their phone. And many of them are doing this while carrying $15,000, $25,000, or $40,000 in credit card debt at interest rates above 20%. That disconnect — investing for the future while hemorrhaging money to credit card interest in the present — is one of the most common and most costly financial mistakes we see. So let's talk about the investing myths that contribute to it.

Myth #1: You Need Big Money to Start Investing

This used to be true and isn't anymore. Decades ago, investing required a stockbroker, minimum account balances of thousands of dollars, and trading commissions that made small investments impractical. Today, apps like Robinhood, Fidelity, Schwab, and others let you open a brokerage account with no minimum, buy fractional shares of any stock or ETF, and pay zero commissions on trades. You can literally start investing with $5. The democratization of investing has been one of the most positive financial developments of the past decade.

So the myth that you need "big bucks" to invest is definitively busted. A 10% return on $500 is still a 10% return, whether you're investing $500 or $500,000. However — and this is where the myth becomes dangerous for people in debt — the ease of investing has created a new problem: people investing small amounts while ignoring large debts. Putting $100 per month into a stock market index fund that averages 10% annually while carrying $20,000 in credit card debt at 22% APR is like pouring a glass of water into a bucket that has a hole in the bottom. Yes, the water is going in. But it's draining out much faster than you can fill it.

Myth #2: The Stock Market Is Just Gambling

This myth persists partly because of the way investing is sometimes portrayed in popular culture — fast-talking traders, meme stocks, crypto moonshots, and people either getting spectacularly rich or losing everything overnight. That version of investing absolutely does resemble gambling. Day trading, options speculation, and chasing viral stock tips are all forms of financial risk-taking where the odds of consistent success are stacked against individual investors. The Dalbar Quantitative Analysis of Investor Behavior has consistently shown that the average equity investor significantly underperforms the market, largely due to emotional decision-making and market timing.

But long-term, diversified investing is fundamentally different from gambling. When you buy a diversified index fund (like one that tracks the S&P 500), you're buying a small piece of hundreds of the largest, most profitable companies in America. Over any 20-year period in the history of the S&P 500, the index has delivered positive returns. The average annualized return of the S&P 500 over the past 30 years is approximately 10.5% before inflation (Source: Fidelity's research on long-term market returns). That's not a gamble — it's a well-documented historical pattern supported by the fundamental tendency of the American economy to grow over time.

Investing is not gambling. But — and we keep coming back to this — investing while carrying high-interest debt is not smart either. The SEC's investor education materials emphasize that the expected long-term return of a diversified stock portfolio is 7% to 10% annually. Credit card APRs in 2026 average 22.76% (Source: Federal Reserve's latest consumer credit data). The gap between what you might earn and what you're definitely paying is enormous. Recognizing that investing isn't gambling is important. But recognizing that debt elimination is a guaranteed return that exceeds market expectations is equally important.

Myth #3: I Missed My Opportunity — That Ship Has Sailed

More often than not, investors write off opportunities because they didn't buy at the "perfect" time. They saw a stock at $50, hesitated, watched it climb to $100, and concluded they missed their chance. This happens with broader market investing too — people look at the S&P 500 at all-time highs and decide it's too late to get in. It's nearly impossible to perfectly time the market, and the data overwhelmingly shows that time in the market beats timing the market.

But here's the version of this myth that's most relevant to people carrying debt: "I should have started investing years ago, so now I need to invest aggressively to catch up." This mindset leads to a particularly destructive behavior pattern — maxing out investment contributions while making only minimum payments on high-interest debt. The urgency to "catch up" on investing causes people to ignore the mathematical reality that their debt is growing faster than their investments.

You haven't missed the ship. The stock market will be there when you're ready. What you have missed, if you're carrying $20,000+ in credit card debt, is the opportunity to stop paying $4,500 or more per year in interest that is enriching credit card companies instead of building your wealth. Eliminating that debt IS the investment. It's a guaranteed return that exceeds what any market index has reliably delivered. Once the debt is gone, you can invest from a position of strength — without the drag of high-interest payments undermining every dollar you put into the market.

The Math: Debt Payoff vs. Market Returns

Let's put real numbers to this, because the math is genuinely striking. Assume you have $20,000 in credit card debt at 22% APR, and you have an extra $500 per month beyond your minimum payments that you could direct either toward debt payoff or toward investing.

If you invest that $500 monthly in a diversified portfolio averaging 10% annual returns (the historical S&P 500 average), after 3 years you'd have approximately $20,900 in your investment account. Meanwhile, your credit card debt — assuming you're making only minimum payments — has barely budged. You're still paying around $4,400 per year in interest alone. Over those 3 years, you've paid approximately $13,200 in interest to the credit card companies. Your net gain: roughly $7,700 ($20,900 in investments minus $13,200 in interest paid).

Now consider the alternative. You put that same $500 per month toward your credit card debt. Combined with your minimum payments, you'd eliminate the entire $20,000 balance in approximately 2.5 to 3 years and save roughly $8,000 to $12,000 in interest that you would have otherwise paid. Once the debt is gone, you redirect the full amount — your $500 plus what you were paying in minimums — into investments. You start investing 6 months later than in scenario one, but you start from zero debt, with more available cash flow, and without the constant drag of interest payments. Within a few years, you've pulled ahead and you've done so without the psychological weight of carrying debt.

The guaranteed return of eliminating 22% APR debt will outperform the expected return of market investing in virtually every scenario. And it's guaranteed — the stock market might return 10%, or 5%, or negative 15% in any given year. Your credit card definitely charges 22%, every single month, without exception. We've written about how to make better financial decisions before, and the conclusion is always the same: when the guaranteed cost of your debt exceeds the expected return of your investments, the debt wins. Pay it off first.

When It Does Make Sense to Invest While in Debt

We're not absolutists, and there are scenarios where investing while carrying some debt is reasonable. If your employer offers a 401(k) match (say, matching 50% of contributions up to 6% of your salary), that's a guaranteed 50% immediate return on your contribution. That exceeds even credit card interest rates, so contributing enough to capture the full employer match while simultaneously paying down debt is smart. Don't leave free money on the table.

If your debt is low-interest (below 6% to 8%), such as federal student loans, a mortgage, or a low-rate auto loan, the expected returns from diversified market investing are likely to exceed your debt's interest rate over the long term. In that case, investing and making normal debt payments simultaneously makes mathematical sense. But credit card debt at 20%+ APR is not in this category. Not even close.

If you're already enrolled in our debt relief program or working through a structured repayment plan, the monthly deposits you're making toward your debt resolution are effectively your highest-return "investment." Once the program is complete and your debts are resolved, you'll have the cash flow to invest aggressively — and you'll be doing it from a foundation of zero high-interest debt, an emergency savings fund, and a strategy for maintaining and rebuilding your credit after debt relief. That's the position you want to invest from.

The Biggest Investing Myth of All

The biggest investing myth isn't that you need big money, or that the market is gambling, or that you've missed your window. The biggest myth, for anyone carrying significant credit card debt, is that investing is more important than debt elimination. It's not. Investing builds wealth over decades. High-interest debt destroys wealth every single month. You can't plant a garden and grow a harvest while the ground beneath you is on fire.

Get the debt handled first. Build your emergency fund. Then invest with confidence, knowing that every dollar you put into the market is actually working for you — not being silently offset by $0.22 per year in credit card interest on every dollar you still owe. The market will wait for you. Your credit card company, on the other hand, will not.

Everyone has to start somewhere, and many of the investors you admire started small. That part of the conventional wisdom is absolutely true. But starting your investing journey while carrying a mountain of high-interest debt is like running a race with a weight vest on. You can still move forward, but you're making it so much harder than it needs to be. Take the vest off first. Then run. The difference in speed — and in how good it feels to run without it — is something you have to experience to fully appreciate.
