Letters: Inherited $100K, But Drowning in High-Interest Debt – What Should I Do?

Dear Torn in Texas,

I understand completely why you feel paralyzed. Receiving an inheritance is a significant event, often tinged with grief, and then facing such a critical financial decision can be overwhelming. It’s commendable that you want to honor your Aunt Clara’s hard work by making a wise choice.

Let's cut through the noise from your friends and focus on the numbers. As a Certified Financial Analyst (CFA) and Certified Financial Planner (CFP), my advice is always grounded in what provides the most certain and beneficial outcome for your financial health.

First, let's address your credit card debt. With interest rates ranging from 22-25% Annual Percentage Rate (APR), this is extremely expensive debt. The average credit card interest rate for accounts accruing interest is around 22.15% as of May 2026, so your rates are unfortunately typical for high-interest credit cards. When you pay down debt at these rates, you are essentially getting a guaranteed, risk-free return on your money equal to that interest rate. Think of it: if you pay off a credit card with a 25% APR, you are saving yourself from paying 25% interest, which is an immediate 25% return on the money you use to pay it off. This return is also tax-free.

Now, let's compare that to investing. While the stock market can offer significant returns over the long term, it also carries risk. For 2026, forecasts for the S&P 500 vary, with some analysts projecting returns between 6% and 24%. However, these are projections, not guarantees. The market can go up or down. A guaranteed 22-25% return from debt repayment far outweighs the uncertain, though potentially higher, returns of the stock market, especially when you consider the risk involved.

Here’s my recommended plan of action:

1. Bolster Your Emergency Fund Immediately: Your current $3,000 emergency fund is a good start, but it's small for your income level. Financial experts recommend having three to six months' worth of living expenses saved. Given your $60,000 annual income ($5,000 per month), aim for at least $15,000 to $30,000. Take a portion of your inheritance, perhaps $10,000-$12,000, and add it to your existing fund. This will give you a solid cushion against unexpected expenses like job loss or medical emergencies, preventing you from falling back into high-interest debt.

2. Attack the High-Interest Debt: After securing your emergency fund, use the bulk of the remaining inheritance to pay off your credit card debt ($30,000 at 22-25% APR) and your personal loan ($15,000 at 12% APR). This is a total of $45,000. Clearing these debts will free up significant cash flow in your monthly budget that was previously going to interest payments. The average personal loan interest rate is around 12.42% as of June 2026, so your loan is also quite costly. This step alone will eliminate 45% of your total debt.

3. Address the Car Loan: With your credit card and personal loan debt gone, you'll have more financial breathing room. Your car loan at 6% APR is much lower interest. You can choose to pay this off as well, or you can continue making regular payments if you prefer to keep some of the inheritance for investment. Given the 6% rate, it's less urgent than the others, but still a solid option for a guaranteed return.

4. Invest What Remains (Thoughtfully): After addressing your emergency fund and high-interest debts, you will likely have a significant portion of your inheritance left (e.g., $100,000 inheritance - $10,000 emergency fund - $45,000 high-interest debt = $45,000, plus potentially the car loan amount if you paid it off). This is when you can begin investing for long-term growth. Consider diversified, low-cost index funds or exchange-traded funds (ETFs) that track the broader market. You could also explore contributing to a Roth IRA or increasing your 401(k) contributions if you have access to one through your employer.

Your cousin Mark is right that you're throwing money away on interest, but investing isn't inherently wrong; it's about timing and prioritization. Your friend Sarah's advice about 'money making money' is true in principle, but not when you're simultaneously losing significantly more money to high-interest debt. By eliminating that guaranteed loss first, you build a much stronger foundation for future wealth creation.

This situation is an opportunity to transform your financial future. Take a deep breath, follow these steps, and you'll be well on your way to financial freedom. You've got this.

Sincerely,

Robinson Roacho, CFA, CFP
