If you’re in your 20s, retirement probably feels like a lifetime away. Between getting established in your career, managing bills or student loans, and trying to enjoy life, your 401(k) usually isn’t top of mind.
That’s completely normal.
But after working with many people early in their careers, we’ve noticed a consistent pattern: your 20s quietly set the foundation for your entire financial future—and most people don’t realize it until much later.
The good news? A few smart moves (and avoiding a handful of common money mistakes) can make an enormous difference over time.
Money Mistakes to Avoid in Your 20s – According to Financial Advisors
Here are some of the biggest financial mistakes we see, and how to fix them before they become costly.
1. Waiting Too Long to Get Started
One of the biggest mistakes with money for younger people is not contributing at all, or telling yourself you’ll “start later when things settle down.”
Here’s the reality: time is your greatest advantage. Every year you wait is a year of compounding you don’t get back. That doesn’t mean you need to contribute a lot right away—just that getting started matters far more than getting everything perfect.
Small contributions today are often more powerful than larger ones you start later.
2. Not Taking Full Advantage of the Employer Match
If your employer offers a 401(k) match and you’re not contributing enough to get it, you’re leaving money on the table.
Think of the match as part of your compensation. It’s guaranteed. It doesn’t depend on the market. And it’s one of the easiest wins in personal finance.
At a minimum, aim to contribute enough to receive the full match. Anything less is essentially turning down free money.
3. Playing It Too Safe Too Early
We sometimes see people in their 20s investing very conservatively, sitting in cash or ultra-stable funds because market ups and downs feel uncomfortable.
But with decades until retirement, short-term volatility matters far less than long-term growth. In fact, being too conservative can actually work against you by limiting your ability to grow wealth and keep up with inflation.
In your 20s, having some volatility isn’t a flaw—it’s part of the opportunity.
4. Never Increasing Contributions as Your Income Grows
Many people set their contribution rate when they first start working and never revisit it. A 3–5% contribution might feel reasonable early on, but if it stays there for years, it often won’t be enough.
The good news is you don’t have to make dramatic changes. Small increases—especially tied to raises or promotions—can add up in a big way over time, without impacting your lifestyle.
Incremental changes matter more than dramatic ones.
5. Cashing Out When You Change Jobs
Job changes are common in your 20s, but cashing out a 401(k) during a transition can be one of the most expensive financial mistakes you make.
Between taxes, penalties, and lost future growth, what feels like a short-term boost can seriously slow your long-term progress.
Whenever possible, rolling your account into a new employer plan or an IRA helps you stay on track and keep momentum.
6. Not Knowing What You’re Actually Invested In
Setting up your 401(k) and forgetting about it isn’t always a bad thing, but never checking in can lead to investments that don’t truly align with your goals.
We sometimes see accounts that are outdated, poorly diversified, or mismatched for someone’s time horizon.
You don’t need to monitor your account constantly. But understanding where your money is invested and why makes a difference.
The Bottom Line On Making Common Financial Mistakes in Your 20s
If any of this sounds familiar, don’t worry. These mistakes are common and often fixable. The earlier you address them, the easier it is to build meaningful long-term wealth with less stress and effort.
You don’t need to have everything figured out in your 20s. You just need to start paying attention and make thoughtful adjustments along the way.
And that’s a decision worth making sooner rather than later.
