If you work for a company that still offers a traditional pension, you're part of a shrinking club.
Only about 15% of private-sector workers have access to one, according to federal data.
Everyone else is largely on their own with a 401(k), an IRA, or whatever they can stash away.
The two plans work in completely different ways, and that difference shows up in your paycheck and your risk.
Stay long enough to vest, and your employer owes you a set monthly check for life, usually based on your salary and years of service.
You don't pick investments, you don't watch the market, and you don't run out of money if you live to 95.
You contribute, your employer may match part of it, and the balance rises or falls with the investments you choose.
The downside is that the entire outcome rests on how much you save and how the market behaves.
That shift matters more than most people realize.
A pension spreads longevity risk across a large pool of workers and a company backing the plan.
A 401(k) puts that risk on one household.
If the market drops 30% the year you retire, that's your problem, not a shared one.
A typical employer match is 50% of contributions up to 6% of pay, which works out to a 3% salary bump if you contribute enough to capture it.
Leaving that on the table is one of the most common and costly mistakes in personal finance.
Companies freeze plans, underfund them, or hand them off to insurers.
Public pensions in some states face their own funding gaps.
A pension is only as solid as the employer or fund standing behind it.
If you have a 401(k), a few habits do most of the work.
Contribute at least enough to get the full match.
Keep fees low, since a 1% annual fee can quietly eat a big chunk of your balance over 30 years.
And resist the urge to check your balance daily, because panic selling is how retirement accounts turn temporary dips into permanent losses.
If you're lucky enough to have both, treat the pension as your income floor and the 401(k) as the growth piece.
That combination covers basic bills with the guaranteed check and gives you flexibility for everything else.
For anyone with only a 401(k), the honest answer is that you're your own pension administrator now.
That means picking a contribution rate you can live with, automating it, and bumping it up every time you get a raise.
The real question isn't which plan is better on paper.
It's whether the money you'll need at 70 is being set aside at 30, 40, and 50, and whether it's invested in something you understand.
Our take: A pension is a great deal if you have one, but it's not coming back for most workers.
The 401(k) rewards people who start early, keep costs low, and leave the money alone.
Final Thoughts
Boring, unglamorous, and probably the most reliable path most Americans have left.
