The retirement plan you pick could quietly cost you six figures, and most workers never run the numbers until the final years of their career.
A pension and a 401(k) sound like two paths to the same destination, but they behave nothing alike when it comes to risk, taxes, and how long your money actually lasts.
Pensions are vanishing from the private sector.
Only about 15% of private-industry workers still have access to a defined-benefit plan, according to federal labor data, down from roughly a third in the early 1990s.
If you're offered one today, you're holding something increasingly rare.
The trade-off: you usually surrender control.
Your employer invests the money, decides the payout formula, and hands you a check for life.
You own the account, choose the investments, and bear every market swing yourself.
The upside is flexibility and portability.
The downside is that the burden of not outliving your savings lands squarely on you.
A 401(k) pays until the balance hits zero.
Traditional 401(k) contributions lower your taxable income now, but withdrawals get taxed as ordinary income later.
Many pensions work similarly, taxing you on the back end.
Roth 401(k) dollars flip it, taxing you today so qualified withdrawals come out clean in retirement.
Which wins depends heavily on your bracket now versus later — a guess most people make badly.
The average employer match sits around 4% to 5% of salary, and skipping it is essentially refusing free money.
A pension has no match because the employer funds the whole thing.
That difference matters when you job-hop.
Pensions often reward long tenure through vesting schedules, while 401(k) balances follow you out the door immediately.
Annuity-style certainty is where pensions shine.
Retirees with a guaranteed monthly check can budget with confidence and don't panic-sell during downturns.
Underfunded plans and corporate bankruptcies have trimmed benefits before, and some workers have watched promised payouts get restructured.
For the growing majority without a pension, the 401(k) is the whole game.
That means contribution rate matters more than almost anything else.
Financial planners commonly suggest aiming to replace 70% to 80% of pre-retirement income, a target that's hard to hit while contributing under 10% of salary for decades.
One practical move: if you have a pension, treat your 401(k) or IRA as the inflation-fighter and bridge fund, not the main event.
If you don't, your savings rate, asset allocation, and withdrawal strategy carry the entire load.
Running a few retirement calculators before open enrollment costs nothing and often changes behavior fast. **The bottom line:** a pension sells you certainty, and a 401(k) sells you control — you rarely get both.
Final Thoughts
Know which one you're actually holding, because guessing wrong doesn't show up until the paychecks stop.
