A pension is a retirement plan in which your employer promises to pay you a monthly benefit for life after you retire, based on your years of service and salary. It’s the original retirement system — and it’s increasingly rare in the private sector, where 401(k)s have largely replaced it. But pensions still cover millions of public-sector workers and retirees from large companies.
Defined Benefit vs. Defined Contribution
Retirement plans fall into two big categories:
- Defined benefit (pension): The employer promises a specific monthly amount in retirement. The employer takes on the investment risk — they must fund the plan well enough to pay all future obligations.
- Defined contribution (401(k), 403(b)): The employer (and you) contribute money to your account. The amount you have in retirement depends on how much went in and how the investments performed. You take on the investment risk.
A pension shifts risk from the worker to the employer; a 401(k) does the opposite. That’s why pensions are so much more expensive to provide — and why most private employers have stopped offering them.
How a Pension Benefit Is Calculated
The most common formula:
Years of service × Final average salary × Benefit multiplier = Annual pension
For example: 30 years of service × $80,000 final average salary × 2% multiplier = $48,000 per year for life.
Each plan defines its own terms — what counts as “final average salary” (last year? Highest 3 of last 5? Last 5 averaged?), what the multiplier is (typically 1% to 2.5%), and when you become eligible to retire with full benefits (often after a set number of years of service and reaching a minimum age).
Who Still Has Pensions
- Government workers: Federal, state, and local employees — including teachers, firefighters, police, postal workers, and military — overwhelmingly still have pensions.
- Union members in some industries: Many union jobs still come with multi-employer pension plans.
- Some large private-sector retirees: Many established companies froze new pension enrollment but continue paying out to existing retirees.
- A small minority of current private-sector workers: A handful of companies still offer pensions, mostly in regulated industries (utilities, defense, some manufacturing).
Vesting and Portability
Most pensions require you to work for a minimum period — often 5 or 10 years — before becoming fully vested in the benefit. Leaving before then can mean leaving with little or nothing.
Pensions are generally not portable. If you leave your employer before retirement, you typically can’t roll the pension into another account the way you can with a 401(k). You’ll either get a deferred benefit (paid out when you reach retirement age) or, in some cases, a lump-sum buyout option.
Lump Sum or Monthly Payments?
Some pension plans offer retiring workers a choice between a lump-sum payout and monthly payments for life. Each has tradeoffs:
- Monthly payments: Guaranteed income you can’t outlive. Protected (within limits) by the federal Pension Benefit Guaranty Corporation if the plan fails.
- Lump sum: Full control over the money, ability to invest, ability to leave a balance to heirs. But you bear the investment risk and could outlive the money.
The right choice depends on your other retirement income, health and life expectancy, comfort managing investments, and whether your spouse needs survivor protection.
Final Thought
A pension is one of the most valuable benefits any job can offer — a paycheck for life. If you have one, understand the formula, the vesting rules, and your options at retirement. If you don’t, your 401(k) and Social Security become the foundation, and it’s on you to save enough that they replace what a pension once would have provided.
