Your Twenties Are a Financial Time Machine—Here's How to Use It

Graduation season brings champagne toasts and family photos, but somewhere between the ceremony and reality sets in a harder truth: you’re about to learn lessons your diploma didn’t prepare you for. And unlike calculus or history, you can’t retake financial decisions—you just live with them.

On Wednesday morning, Kathryn McCall, vice president and financial advisor at Captrust, joined the conversation to talk about the real handoff every recent graduate faces. For high school grads heading to college, her message is blunt: treat education like the investment it actually is. Think through your major not just because it sounds interesting, but because you need to know if that student debt will pay off in a decade. The job market shifts. AI is coming for some careers. You can research earning potential and career trajectories before you commit to four years and $100,000 in loans. It’s a simple move most people skip.

College graduates get their own reality check. Your first job doesn’t define you—your twenties are explicitly for figuring things out—but that doesn’t mean coasting. If you land that job, McCall recommends funneling at least 5% into your employer’s 401(k) or 403(b). And here’s where it gets interesting: if you finish school without loans, land that first gig, and get even a small graduation gift, you’ve hit what McCall calls“the trifecta.”That’s when you throw money into a Roth IRA. Every dollar you save now compounds for decades. That’s not hype. A dollar saved at 22 becomes exponentially more at 60 than a dollar saved at 42.

The money-saving part, though? It’s really about avoiding the traps. Build one healthy credit relationship early: open a single credit card, charge a fixed amount you can afford, pay it off every month, and walk away. Don’t celebrate your first promotion by financing a car you can’t afford outright. Don’t book that impulse wanderlust trip on plastic. Stay within your means because every dollar you don’t spend now is a dollar that keeps working for you in the future.

It sounds boring. It’s meant to be. The real story isn’t about flashy wins; it’s about compounding discipline. Those small, smart choices in your twenties aren’t restrictions—they’re the leverage that lets you retire on your own terms instead of scrambling to catch up later. Your future self is watching.
