Key Takeaways
- Nearly 30% of under-30 job changers cash out their 401(k) and unintentionally erode future retirement wealth as a result.
- Taxes, penalties, and lost decades of compounding can all make small withdrawals extremely costly.
- Instead, consider rolling over your 401(k) or slowing contributions to boost take-home pay as smarter alternatives.
Changing jobs can be exciting, but for many young workers, it comes with a costly misstep: cashing out their 401(k). According to Vanguard, nearly 30% of workers under 30 take a lump sum from their retirement account when leaving a job. The move can feel like quick access to extra cash, but it’s one of the most damaging choices you can make for your long-term wealth.
Between taxes, penalties, and lost investment growth, the true cost can run into hundreds of thousands of dollars of lost wealth by retirement age.
Why You’re Tempted to Cash Out Your 401(k)
When you’re early in your career, your retirement account may not feel significant, especially if your balance is only a few thousand dollars. “When you have a relatively small balance in your 401(k), it can seem like it doesn’t really matter if you cash out,” says Justin Pritchard, founder of Approach Financial. “But that money is an important part of your future. Small amounts grow to bigger amounts over time, but only if you let the money compound.” The younger you are, the more time is on your side.
There’s also the appeal of quick cash in a tight spot. Samantha Mockford, associate wealth advisor at Citrine Capital, says, “It may seem like free money … but it’s important to weigh the opportunity costs.” She notes that contributions made early in life are “most magnified” thanks to compounding, comparing it to “how a small flick of a wrist can move a massive whip” over time.
The Hidden Costs Beyond Taxes and Penalties
The upfront hit can be bigger than most expect. Pritchard explains: “Let’s say you have $10,000, which seems like plenty of money to solve your problems. But if you pay 22% federal income tax plus a 10% early withdrawal penalty, you’ll only end up with $6,800.” Many plans also require 20% mandatory withholding on lump-sum payouts, meaning “the most you can get is $8,000,” and you may still owe more at tax time.
But the biggest loss is the growth you never see. Mockford calculates that a $10,000 balance at age 25 that earns 8% annually could grow to over $217,000 by age 65 in a 401(k)—and that growth is tax deferred. The growth and tax savings “far outweigh” the taxes due later in retirement, she notes.
What to Do Instead
Instead of cashing out, consider rolling over your old 401(k) into your new employer’s plan or an individual retirement account (IRA) to keep the money growing. “If you don’t need all of the money available to you, leave the rest of it in your retirement accounts for the future,” Pritchard says. “It’s not all or none.” Rolling over to an IRA can also help avoid mandatory withholding and give you more control over withdrawals.
If you need to free up cash, Mockford suggests slowing your contributions temporarily to boost your paycheck rather than pulling money out. And to avoid the same dilemma next time, both advisors recommend building an emergency fund. Pritchard suggests contributing enough to get your employer match, then directing extra savings to a high-yield savings account until you’ve built three to six months of expenses. Finally, Mockford also recommends turning irregular but expected costs—like travel or holiday gifts—into a “monthly bill” to yourself so you’re prepared for the expenses without tapping retirement funds.
The Bottom Line
Cashing out a 401(k) early can feel like a short-term fix, but it comes at a steep, long-term opportunity cost. Taxes and penalties take an immediate bite, while lost compounding can shrink your future nest egg by hundreds of thousands. The good news is you can protect your retirement savings by keeping them invested, rolling them over when you change jobs, and shoring up your emergency fund so that you’re not unintentionally eroding your future wealth potential.
