Pension
In common US usage, a pension is an employer-sponsored defined-benefit retirement plan that promises retirement benefits under a formula, often based on pay and years of service.

Your employer's pension statement may show an estimated monthly payment at a particular retirement age rather than money you can withdraw today. A projected pension payment is retirement income, not automatically an account balance you can add to net worth. The estimate may also assume you keep working until that age, so the benefit already earned can be smaller than the benefit projected.
In a sentence
- "My pension formula works out to $1,500 a month for 20 years of credited service."
- "The pension promises retirement payments, while my 401(k) holds an investment balance."
- "I check the pension vesting rules before deciding when to leave the job."
How it works
A defined-benefit pension follows the employer's plan documents, so two plans can produce different benefits for the same salary and years worked.
- Read the benefit formula. A plan may multiply credited years of service by a plan-defined average salary and a benefit multiplier. Check which years and which kinds of pay count rather than assuming the formula uses your final paycheck.
- Check vesting. Vesting determines whether an earned benefit is yours to keep when you leave. Being vested does not necessarily mean you can start receiving payments immediately.
- Check the starting age. Payment eligibility depends on the plan's age and service rules. Starting earlier may reduce the monthly benefit, and an estimate based on future service is not the same as a benefit already earned.
- Compare payment forms. Pension payments commonly provide income for your lifetime. An option that continues payments to a survivor can change the monthly amount, and a lump sum is available only if the plan offers it.
For a plan using a pay-and-service formula, one possible calculation is
Annual pension = benefit multiplier × credited years of service × plan-defined average annual pay
Monthly pension = annual pension ÷ 12
An example
Compare two service histories under a hypothetical plan with a 1.5% benefit multiplier and $60,000 in plan-defined average annual pay. Assume both benefits are fully vested and start at the plan's normal retirement age, without an early-start or survivor-option adjustment.
The 20-year calculation produces $1,500 a month before any taxes or deductions; ten more credited years produce $750 more each month under these assumptions. Neither calculation establishes a cash balance you can withdraw.
Why it matters
The pension estimate changes how much retirement spending your other savings need to cover. Compare expected pension income with essential costs, using income after expected taxes and deductions. Check whether the plan provides increases for inflation; a payment that stays fixed buys less when prices rise.
Pension decisions also affect the income available to someone who survives you. Compare payment forms using both the amount you receive now and what continues after your death, rather than treating the largest starting payment as the only relevant figure.
Pension versus 401(k)
A pension promises a formula-based benefit, while a 401(k) is an individual account whose value depends on contributions, investment results, and fees. With a pension, you estimate retirement income from the plan's formula and payment options. With a 401(k), you start from the accumulated balance and decide how to turn it into retirement income; the balance alone does not promise a particular lifetime payment.
Common questions
What happens to my pension if I leave my job? A vested pension benefit generally stays yours for payment later under the plan's rules. Leaving before vesting may mean losing the employer-funded benefit, and leaving before the retirement date used in a projection can leave you with less service than that projection assumes.
Does every pension offer a lump sum? No. Some plans offer a cash payment instead of some or all of the future monthly benefit, but others do not. A monthly benefit estimate alone does not establish a cash-out option.
Should I include a pension in net worth? For a balance-based net worth statement, use a vested cash value only when the plan documents one; otherwise, show the expected pension income separately. The present value of future payments is a separate estimate, not an account balance, and should not be added alongside a cash alternative for the same benefit.
