A defined benefit pension is a retirement plan in which your employer promises to pay you a set monthly amount for the rest of your life, with the size of that check determined by a formula based on your salary and years of service rather than by an investment account balance. Your employer puts in the money, hires the investment managers, and bears the risk if the fund underperforms. You get the same payment either way. Plans of this type are now concentrated in the public sector and in older unionized industries, but the rules below apply wherever one is offered.
How the Formula Produces Your Monthly Check
Nearly every defined benefit plan uses the same three ingredients: a percentage multiplier, your years of service, and a measure of your average salary. Multiply them together and you get your annual benefit. A plan with a 2% multiplier applied to a 30-year career produces a benefit worth 60% of your average salary. Multipliers typically run between 1% and 2.5%, with the more generous figures showing up in public-sector plans.
The salary piece comes in two forms. Final average pay uses your highest-earning stretch, often the last three or five years, which rewards late-career raises and promotions. Career average pay instead averages what you earned across every year in the plan, which produces a smaller benefit for anyone whose pay climbed significantly over time. Base salary almost always counts. Commissions sometimes do. Overtime and one-time bonuses usually don’t.
Your Summary Plan Description spells out which version your employer uses and what counts as pensionable pay. Reading it once, carefully, is worth more than any general explanation.
When You Actually Own the Benefit
You do not own your pension the moment you start accruing it. Vesting is the process by which the benefit becomes legally yours, and until you’re vested, leaving the job means walking away with nothing.
Federal law gives employers two options. Cliff vesting takes you from 0% to 100% after five years of service, with no partial credit for leaving at four years and eleven months. Graded vesting phases ownership in over seven years: 20% at three years, then 20 points more each year until you hit 100% at seven.1Office of the Law Revision Counsel. 29 U.S. Code 1053 – Minimum Vesting Standards Plans can vest faster than these schedules but never slower.2U.S. Department of Labor. FAQs about Retirement Plans and ERISA
A year of service for vesting generally means at least 1,000 hours worked in the plan year. Part-time stretches and extended leaves can cost you credit. Long absences can cost you more than that: if you leave without any vested benefits and your consecutive break years equal or exceed your prior service, the plan can wipe out your earlier service entirely and restart your vesting clock.3eCFR. 26 CFR 1.410(a)-5 – Year of Service; Break in Service
Once vested, your right to the benefit survives even if you leave the company decades before retirement. The plan freezes your accrued benefit as of your departure date, and you collect when you reach the plan’s normal retirement age. This is called a deferred vested benefit. It will be smaller than what a career employee receives because you stopped adding service years, and most plans don’t adjust the frozen amount for inflation. Forgetting about an old pension is more common than people assume. The Department of Labor and the PBGC both maintain records that can help you track one down.
Retiring Early Costs You
Most plans set a normal retirement age (often 65) and an early retirement age (commonly 55). You can start collecting before the normal age if you’ve met the service requirements, but the monthly check will be permanently smaller to account for the longer payout period.
A common reduction runs around 5% to 6% for each year you retire before normal retirement age.4Bureau of Labor Statistics. Early Retirement Provisions in Defined Benefit Pension Plans Under that kind of schedule, leaving at 60 instead of 65 can shrink your benefit by 25% to 30% for life. Some plans use a smaller reduction in the years just before normal retirement and a steeper one further out. Check the exact schedule in your Summary Plan Description before committing. This is one of those decisions you cannot undo.
Choosing How You Get Paid
When you reach retirement, you’ll pick the form in which you receive the benefit. That choice is largely irreversible.
Single Life vs. Joint-and-Survivor Annuity
A single life annuity pays the highest monthly amount, but payments stop the day you die. A joint-and-survivor annuity pays a smaller amount while you’re alive and then continues paying your surviving spouse, usually at 50% or 75% of the original benefit.
If you’re married, federal law defaults you into a joint-and-survivor form. Your spouse has to consent in writing to waive it, and the signature must be witnessed by a plan representative or a notary.5Office of the Law Revision Counsel. 29 U.S.C. 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity Congress built that requirement in because too many retirees had been choosing the bigger single-life check and leaving surviving spouses with nothing.
Lump Sum
Some plans let you take the entire present value of your pension as a one-time cash payment instead of monthly checks. The plan calculates the amount using interest rates and mortality assumptions set by the Internal Revenue Code.6Internal Revenue Service. Minimum Present Value Segment Rates When interest rates are low, lump sums are larger, because the plan needs more money upfront to replicate those future payments. When rates rise, lump sums shrink. Taking the cash gives you control over how it’s invested, but you give up the longevity protection of a guaranteed lifetime payment. Most people who take lump sums roll them into an IRA to avoid an immediate tax bill.
If You Die Before You Start Collecting
If you die after vesting but before benefits begin, your surviving spouse is entitled to a qualified preretirement survivor annuity. The plan pays your spouse a lifetime benefit calculated as if you had retired the day before your death and chosen the joint-and-survivor form.5Office of the Law Revision Counsel. 29 U.S.C. 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity Plans can require a one-year marriage before this protection applies.
Inflation Will Eat Into the Check
Most private-sector pensions pay a fixed dollar amount that never increases. Bureau of Labor Statistics data shows only about 4% of private-sector participants have automatic cost-of-living adjustments. Over half of public-sector plans include some form of inflation protection.7Bureau of Labor Statistics. Public and Private Sector Defined Benefit Pensions – A Comparison A benefit that feels comfortable at 65 can lose a large chunk of its purchasing power by 85. If the pension is your main income source, build that erosion into your planning.
Taxes on Your Pension
Pension payments are taxed as ordinary income in the year you receive them. If you never made after-tax contributions to the plan, which is the typical private-sector arrangement, every dollar is fully taxable.8Internal Revenue Service. Topic No. 410, Pensions and Annuities If you did make after-tax contributions, that portion comes back to you tax-free, spread over the expected payment period. Federal income tax withholding applies much like it does to a paycheck.
Taking a distribution before age 59½ adds a 10% penalty on top of regular income tax unless an exception applies.9Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions One useful exception: if you separate from service during or after the year you turn 55, the 10% penalty does not apply to distributions from that former employer’s plan.
If you haven’t started collecting by age 73, required minimum distribution rules force the plan to begin paying you.10Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Most retirees start well before then. If you’re still working past 73 and don’t own 5% or more of the company, you can delay distributions from your current employer’s plan until you actually retire.
Dividing a Pension in Divorce
Pension benefits earned during a marriage are generally marital property. To divide them, a court issues a Qualified Domestic Relations Order (QDRO). Federal law usually prohibits plans from paying anyone but the participant; the QDRO is the specific exception that lets a spouse, former spouse, or dependent receive a share.11Office of the Law Revision Counsel. 29 U.S. Code 1056 – Form and Payment of Benefits
The order has to spell out the amount or percentage going to the alternate payee, along with names and addresses. It cannot award a type or amount of benefit the plan doesn’t otherwise provide.12Internal Revenue Service. Retirement Topics – QDRO: Qualified Domestic Relations Order A former spouse who receives benefits under a QDRO reports and pays tax as if they were the plan participant and can roll the distribution into an IRA. Getting the document drafted correctly usually requires a specialized attorney, with fees typically running from several hundred to over a thousand dollars.
If Your Employer Can’t Pay
Private-sector defined benefit plans fall under the Employee Retirement Income Security Act of 1974, which sets funding, disclosure, and fiduciary rules.13Office of the Law Revision Counsel. 29 U.S. Code 1082 – Minimum Funding Standards Public-sector and church plans are generally exempt from ERISA and operate under state law or their own governing documents, which also means the federal backstop below doesn’t cover them.
If a private employer goes bankrupt or can no longer fund the plan, the Pension Benefit Guaranty Corporation steps in as trustee. The PBGC is a federal agency funded by premiums employers pay annually, set at $111 per participant for single-employer plans in 2026.14Pension Benefit Guaranty Corporation. Premium Rates It pays benefits up to a legal maximum, which may be less than the plan originally promised.15Pension Benefit Guaranty Corporation. How Pension Plans End
For plans taken over in 2026, the PBGC maximum monthly guarantee for a 65-year-old retiree receiving a straight-life annuity is $7,789.77 per month, or about $93,477 a year. The cap is lower if you retire before 65 or choose a joint-and-survivor form.16Pension Benefit Guaranty Corporation. Maximum Monthly Guarantee Tables Workers whose promised benefit exceeds the PBGC cap lose the difference if the plan is terminated, which is a real risk for high earners in underfunded plans. Your employer is required to send you an annual funding notice. Read it.
