For decades, the workplace retirement plan was simple: you showed up, you stayed for 30 years, and you collected a pension check for life.
Today, roughly 15% of private-sector workers still have access to a traditional defined-benefit pension, down from about 35% in the early 1990s.
In its place sits the 401(k), a plan that shifts the burden of saving and investing onto you.
Employers love it because the costs are predictable.
Workers inherit something else entirely: the risk of outliving their money.
The difference comes down to who carries the risk.
A pension guarantees a set monthly payment, often calculated on salary and years of service.
That promise is backed by your employer and, in many cases, a federal insurance program.
A 401(k) balance depends on how much you contribute and how markets perform.
That distinction matters more as Americans live longer.
A retiree with a $500,000 401(k) balance who withdraws 4% a year gets roughly $20,000 annually, before taxes.
A pension formula paying 1.5% per year of service on a $70,000 salary after 30 years produces about $31,500 a year, guaranteed for life.
But 401(k)s win on portability and control.
You can take the account with you when you change jobs, adjust your investments, and pass the balance to heirs.
Leave too early and you may get nothing or a reduced payout.
Some pension systems have also cut benefits when funding shortfalls hit.
Vanguard data shows many workers contribute below the level needed to replace their income, and few max out the annual limit.
Auto-enrollment and target-date funds have helped, but millions still cash out when they switch jobs, forfeiting decades of compounding.
Employers have quietly split the difference.
Some now offer a cash balance plan, a hybrid that looks like a pension on paper but grows like an account.
Others pair a smaller 401(k) match with profit-sharing contributions.
For workers weighing a job offer, the comparison is not just about salary.
A pension worth thousands a year in guaranteed income can offset a lower paycheck.
A generous 401(k) match, on the other hand, only pays off if you actually invest it and leave it alone.
The practical move: ask for the plan documents before you accept an offer.
Find out whether the pension is vested, how it is funded, and whether the employer has frozen it.
If it is a 401(k), check the match formula, the fees, and the default investment options.
Those three details quietly decide whether you retire comfortable or keep working past 70.
One more thing: nothing stops you from treating your 401(k) like a pension.
Contribute steadily, ignore the noise, and resist the urge to check the balance daily.

The people who win this game rarely pick the flashiest plan.
