The hidden costs of a hands-off retirement account (Ad)

Contributing to your 401(k) consistently is good financial behavior - but contributing and optimizing are two different things. High fees, heavy company stock concentration, and target-date funds that follow a formula rather than your situation can quietly erode your balance over time. 74% of U.S. millionaires work with a financial advisor - more than double the general population rate. A fiduciary advisor can review your 401(k) for fees, allocation, and alignment with your actual timeline. SmartAsset's free quiz matches nearly 50,000 people each month with vetted fiduciary advisors in their area.tc pixel
