A 401(k) and a pension are not the same thing

A 401(k) is a retirement savings account that you fund yourself, usually through payroll deductions from your employer. A pension is a monthly payment for life that your employer funds and manages, and you receive it automatically after you retire. The core difference: with a 401(k), you save money and decide how to invest it; with a pension, your employer promises you a set income stream once you stop working.

The two also work differently in practice. With a 401(k), the money is yours to control — you choose how much to contribute (up to annual limits set by the IRS), which investments to pick, and when to withdraw it. With a pension, you have no control over the money while working; your employer decides the contribution amount and investment strategy. When you retire, the pension pays you a fixed amount each month for as long as you live, regardless of market performance.

Many people today have a 401(k) but no pension. Pensions were more common decades ago and are now rare in the private sector, though they remain standard for government employees, teachers, and some union workers. If you have both, they work alongside each other — the pension provides a may provide base income, and the 401(k) is additional savings you control.

Key Takeaways

  • A 401(k) is a savings account you fund and control; a pension is a may provide monthly payment your employer funds and manages.
  • With a 401(k), you choose how much to save and how to invest it; with a pension, your employer makes those decisions.
  • Pensions pay the same amount every month for life; 401(k) payments depend on how much you saved and how your investments performed.
  • Most private-sector jobs offer a 401(k) only, while government and union jobs are more likely to include a pension.

How contributions work: who puts money in

With a 401(k), you contribute the money. Your employer may match part of what you contribute — for example, matching 50 cents for every dollar you put in, up to 6 percent of your salary — but the money comes from your paycheck. You decide the percentage, and it comes out before taxes (in a traditional 401(k)) or after taxes (in a Roth 401(k)).

With a pension, your employer contributes all the money. You do not put anything in. The employer sets aside funds each year based on calculations about how much they will owe you in retirement. You have no say in the amount or how it is invested. The employer (or a professional fund manager they hire) handles all investment decisions.

How payouts work: what you receive in retirement

A 401(k) payout depends entirely on what you saved and how your investments grew. If you contributed $500 per month for 30 years and your investments earned 6 percent annually, you might have $600,000 at retirement. You can then withdraw that money in a lump sum, take monthly distributions, or use a combination. The amount you get is not may provide — it depends on your contributions and investment returns.

A pension payout is a fixed monthly amount for life. Your employer calculates it using a formula based on your salary history and years of service. For example, a common formula is 2 percent of your average salary multiplied by years worked. If you earned an average of $50,000 and worked 25 years, you might receive $25,000 per year ($2,083 per month) for life. That amount does not change, even if you live to 100.

The pension is also protected by law. If your employer goes bankrupt, the Pension Benefit Guaranty Corporation (PBGC), a federal agency, steps in and pays your pension up to a legal limit (which varies by year but is currently around $5,800 per month for someone retiring at 65). A 401(k) has no such may provide — if your employer fails, your money is yours to keep, but if your investments lost value, that loss is real.

Investment risk: who bears the cost of market losses

With a 401(k), you bear the investment risk. If the stock market drops 20 percent and your 401(k) is invested in stocks, your account balance drops 20 percent too. If you retire during a market downturn, you have less money. If the market recovers, you benefit from the gains. You control the risk by choosing your investments — you can pick conservative options (bonds, stable funds) or aggressive ones (stocks), or a mix.

With a pension, your employer bears the investment risk. If the pension fund's investments lose money, your employer must still pay you the promised amount. If investments perform well, the employer benefits, not you — your payment stays the same. This is why pensions are called "defined benefit" plans: the benefit (your monthly payment) is defined and may provide, regardless of investment performance.

Portability: what happens if you change jobs

A 401(k) is portable. If you leave your job, the money stays yours. You can roll it into a new employer's 401(k), move it to an IRA (Individual Retirement Account), or leave it where it is. You keep all the money you contributed plus any employer match and investment gains. You can access it (with tax penalties if you are under 59½) or let it grow until retirement.

A pension is not portable in the same way. If you leave a job before you are vested (usually after 3 to 5 years), you forfeit the employer's contributions and receive nothing. If you are vested, you have two options: leave the money with your former employer and collect the pension at retirement age, or take a lump-sum payment now (if the plan allows it). You cannot move a pension to a new job — each employer's pension is separate.

Tax treatment: when you pay taxes on the money

A traditional 401(k) is tax-deferred. You do not pay income tax on the money you contribute or the investment gains while the money sits in the account. You pay taxes when you withdraw the money in retirement. A Roth 401(k) is the opposite: you pay taxes on contributions now, but withdrawals in retirement are tax-free.

A pension is also tax-deferred while you work. You pay taxes on the monthly payments once you start receiving them in retirement. The amount you owe depends on your total retirement income and tax bracket. Some pensions offer a lump-sum option, which is taxed as ordinary income in the year you receive it.

Frequently Asked Questions

Can I have both a 401(k) and a pension?

Yes. Many government employees, teachers, and union workers have both. The pension provides a may provide base income, and the 401(k) is additional savings. Contribution limits and tax rules apply to each separately, so you can max out both if your income allows.

What happens to my 401(k) if I die before retirement?

Your 401(k) goes to your beneficiary — whoever you named on the account. They inherit the full balance. With a pension, if you die before retirement, your beneficiary typically receives nothing unless you chose a survivor option when you retired, which reduces your monthly payment but continues payments to your spouse or children.

Can I withdraw from my 401(k) early?

Yes, but you will owe income tax plus a 10 percent penalty if you are under 59½. Some plans allow loans or hardship withdrawals with lower penalties. A pension cannot be withdrawn early — you must wait until your plan's retirement age to start receiving payments.

Is a 401(k) safer than a pension?

A pension is safer in the sense that your payment is may provide and protected by federal law. A 401(k) depends on your investment choices and market performance. However, a 401(k) is yours to keep and control; a pension is only as secure as your employer's financial health and the PBGC's protection limits.

Do I have to take my 401(k) money out at a certain age?

Yes. You must start taking required minimum distributions (RMDs) from a traditional 401(k) at age 73 (as of 2023). A Roth 401(k) also requires RMDs at 73, though Roth IRAs do not. A pension has no such requirement — you simply receive your monthly payment for life.
