The retirement plan you pick could quietly cost you six figures over a career — and most Americans never run the numbers.
At the center of it sits a choice that isn't really a choice for many workers: a traditional pension, where your employer promises a set monthly check for life, versus a 401(k), where you fund your own account and shoulder the investment decisions.
Only about 15% of private-sector workers still have access to a defined-benefit pension, according to federal labor data.
That shift matters more than ever as inflation eats into fixed incomes.
A pension's biggest selling point is certainty — you know the amount, it typically adjusts with salary during your working years, and the employer carries the investment risk.
The catch: you usually need to stay at that employer for years to vest, and if the company fails, your benefits can be reduced, though federal insurance backstops most private pensions up to set limits.
You control contributions, often with an employer match that's essentially free money, and you own the balance outright — it moves with you when you change jobs.
The downside is equally real: markets fall, fees nibble at returns, and a 2024 study found the average near-retiree has saved far less than what a comfortable retirement requires.
Vanguard data puts the median 401(k) balance for workers in their early 60s around $90,000 — a fraction of what most people need.
A $90,000 nest egg might throw off roughly $4,000 to $5,000 a year in sustainable withdrawals.
A pension paying $2,500 a month delivers $30,000 a year, guaranteed, for life.
That gap is why some workers who get a lump-sum buyout offer agonize over the decision — and why financial planners say the answer depends on health, other savings, and whether you trust yourself not to outlive the money.
Pensions run on autopilot; 401(k)s require you to opt in, pick funds, and resist panic-selling.
Research consistently shows many workers cash out when changing jobs, triggering taxes and penalties that gut long-term growth.
Automatic enrollment and target-date funds have helped, but they can't fix a savings rate that's too low.
If you have a pension, treat it as the foundation and use a 401(k) or IRA to build on top of it.
If you only have a 401(k), push your contribution rate up with every raise, grab the full employer match, and watch the fees on your fund lineup.
And if you're offered a pension buyout, get the numbers in writing before deciding — the guaranteed income is often worth more than it looks.
The uncomfortable truth is that neither option fixes a retirement system asking individuals to solve a problem that used to be shared.
Pensions spread risk across an employer and a workforce; 401(k)s hand it to you, one account at a time.
Final Thoughts
Knowing which side of that divide you're on — and planning accordingly — is the difference between a retirement you choose and one that chooses you.
