You’ve probably mastered the basics of budgeting, investing, and retirement planning by now. After all, you’ve been handling money for years, right?
Before you get too confident, consider this: thousands of high school students recently competed in a national personal finance challenge, and according to a Wall Street Journal article, the questions they faced would make many adults break a sweat.
These aren’t your typical teenagers obsessing over the latest social media trends. They calculate required minimum distributions, analyze CD rates, and work out stock market gains like seasoned pros. Think you could keep up?
Here are five questions from the competition that separated the financially sharp from the merely confident.
1. The retirement puzzle that stumps adults
First challenge: You’re 73 with $500,000 in your traditional IRA. What’s your required minimum distribution (RMD) for the year?
If you’re stumped, you’re not alone. According to the Wall Street Journal, the correct answer involves dividing your IRA balance by the IRS life expectancy in years for your age, 26.5, based on the Uniform Lifetime Table used in 2024 for individuals aged 73.
That means you must withdraw approximately $18,868 to satisfy your RMD and avoid a penalty of up to 25% on any shortfall.
These high schoolers didn’t just memorize formulas. The Wall Street Journal noted that they also grasped the reasoning behind RMDs: after decades of tax-deferred growth, the IRS expects its share of those retirement funds, ready or not.
2. When compound interest gets complicated
Next up: You’ve got $10,000 to invest in a 5-year certificate of deposit (CD) paying 4.5% interest annually, compounded monthly. What’s your final balance?
According to the Wall Street Journal, the correct answer — calculated using the compound interest formula — is $12,516. However, the real insight came from students who understood the “why”: monthly compounding yields slightly higher returns than annual compounding, a detail that often escapes even seasoned adults.
What stood out wasn’t just their math savvy, but their grasp of the financial trade-off: CDs offer security and predictable returns in exchange for liquidity.
And in today’s volatile market, that kind of certainty is becoming more appealing — even to a generation just learning how to manage money.
3. The hidden cost of trading
Here’s a tricky one: Buy 100 shares at $50 each with a $10 commission. Sell them at $55 per share with another $10 commission. What’s your actual profit?
The instinctive answer is $500 (100 shares × $5 gain). The Wall Street Journal reported that the sharpest students went a step further, deducting $10 commissions to arrive at the correct answer: $480. They’ve already absorbed a lesson that trips up many first-time investors — transaction fees quietly erode returns, especially on smaller trades.
4. Time beats timing, every time
Try this one: There are two retirement savers: one who contributes from age 25 to 35 and then stops, versus another who starts at 35 and saves consistently until age 65. Both invest the same monthly amount and earn the same rate of return. Who ends up with more?
The Wall Street Journal explained that the early starter wins — by a landslide — because compound interest had an extra decade to work its magic. These high school competitors understood what many adults learn far too late: in long-term investing, when you start often matters more than how much you save.
5. Credit card reality check
The final stumper: You’re carrying a $5,000 balance on a credit card with an 18% APR and only making minimum payments of 2% of the balance. How long until you’re debt-free?
Most adults guess a few years. The Wall Street Journal revealed that the reality is far worse: it could take over 30 years, with more than $11,000 in interest paid over that time.
These high school students already grasp a harsh truth that catches millions off guard — minimum payments may feel manageable, but they keep you in debt for decades.
What the students’ success reveals
If these questions threw you, you’re not alone. You are witnessing the impact of better financial education in U.S. schools. As the Wall Street Journal highlighted, these students aren’t just memorizing equations but building financial instincts that can shape their futures.
Twenty states now require high school personal finance courses, a milestone beginning to pay off. The result? A generation that understands how compound interest can either build wealth through investing or erode it through high-interest debt.
They know that opening a Roth IRA at 18 beats waiting until 28. They can spot predatory lending practices that older generations often learned about the hard way.
It’s never too late to raise your own financial game. Those high school competitors didn’t become money wizards overnight. They studied, practiced, and asked questions — the same strategy that works at any age.
Pick one concept that tripped you up. Maybe it’s required minimum distributions or compound interest. Start there. Dive into free tools like Khan Academy’s personal finance lessons or the Federal Reserve’s educational resources.
These students aren’t just prepping for a competition — they’re prepping for real life. They’ll enter adulthood knowing that financial success isn’t just about how much you earn, but how wisely you manage it. If they’re mastering this before they’ve received their first paycheck, what’s stopping you?
