For decades, American workers could count on a pension: a guaranteed monthly check for life, funded entirely by the employer.
Today, most private-sector workers have a 401(k) instead, a retirement account they fund themselves, often with a small company match.
That shift has quietly moved nearly all the risk from employers onto employees.
The difference sounds technical, but it changes everything about how you plan.
A pension pays a set amount based on salary and years of service, no matter what the stock market does.
A 401(k) balance depends on how much you contribute, how your investments perform, and how long you leave the money alone.
Take a worker earning $60,000 with 30 years at a company.
A traditional pension might pay $1,500 to $2,000 a month for life.
That same worker contributing 6 percent to a 401(k) with a 3 percent match could land somewhere between $300,000 and $500,000 by retirement, depending on returns.
That pot has to stretch across 20-plus years, and it can run dry.
Fees and fund choices quietly eat into 401(k) returns.
A plan charging 1 percent in annual fees versus 0.1 percent can cost a saver six figures over a career.
Many workers never check the expense ratios buried in their statements.
Pensions, by contrast, pool money and pay professional managers, so individual workers never see those decisions.
Underfunded plans have cut benefits, and some states and cities have struggled to keep promises.
Companies like General Motors and Sears froze pensions years ago, leaving workers with what they had accrued.
A freeze means you keep the benefit earned so far but stop building new credits.
So what should you do if you have a 401(k), or a choice between the two?
It's an instant return that no pension formula can beat.
Second, check your fund fees and move toward low-cost index options if your plan offers them.
Third, don't cash out when you change jobs; roll it into an IRA or the new plan.
If you're lucky enough to have a pension, treat it as one leg of a stool, not the whole seat.
Pensions can be frozen, and healthcare costs in retirement keep climbing.
Pair the pension with personal savings, and you'll have a buffer if the plan changes.
There's also a middle path: some employers now offer cash balance plans, which look like pensions but grow with interest credits.
Others offer a lump sum instead of monthly payments.
Run the math carefully before choosing, because a lump sum can vanish if markets drop right after you retire.
The bigger lesson is that retirement is now a do-it-yourself project for most Americans.
Nobody is watching your savings rate but you.
Automate contributions, increase them with every raise, and revisit your plan once a year.
Our take: the pension-versus-401(k) debate misses the point.
The real question is whether you're saving enough and keeping fees low, regardless of which bucket holds the money.

Do that, and you'll be better off than most.
