A pension works by having your employer promise you a specific monthly income for life after you retire, funded and invested by the employer rather than by you. The amount is set by a formula built into the plan, usually based on your years of service and your salary near the end of your career. Once you’ve worked long enough to vest, that promise belongs to you. When you retire, the checks start and continue for the rest of your life. About 15 percent of private-sector workers still have access to this kind of plan, though pensions remain common in government and unionized jobs.
Pension vs. 401(k): Who Carries the Risk
In a 401(k), you contribute part of your paycheck, choose your own investments, and retire with whatever the account happens to be worth. If the market drops 30 percent the year before you retire, your balance drops with it. You carry the investment risk.
A pension flips that. Your employer promises a specific monthly payment, calculated by a formula locked in when you’re hired. The employer funds a trust, hires actuaries and investment managers, and absorbs every market swing. When you retire, the promised amount arrives every month regardless of what the stock market did last quarter. That predictability is the appeal, and it’s also why pensions cost employers so much to maintain.
When the Benefit Becomes Yours
You don’t earn your full pension on day one. Federal law under the Employee Retirement Income Security Act sets minimum standards for how quickly you build a permanent right to your benefits through vesting. Once vested, your employer cannot take back what you’ve earned, even if you leave years before retirement.
For defined benefit plans, employers pick one of two structures. Under cliff vesting, you have no vested right until you complete five years of service, at which point you become 100 percent vested all at once. Under graded vesting, you own 20 percent of your accrued benefit after three years, 40 percent after four, 60 percent after five, 80 percent after six, and 100 percent after seven.
These are the legal minimums, and many employers vest participants faster.1Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards If you leave before reaching full vesting, you forfeit the unvested portion. Someone who quits after four years under a cliff plan walks away with nothing from the employer’s contributions.
Breaks in Service
Extended time away from work can affect your vesting progress. You incur a one-year break in service if you complete fewer than 500 hours during a plan year.2eCFR. 29 CFR 2530.200b-4 – One-Year Break in Service A single break doesn’t necessarily wipe out prior service, but multiple consecutive breaks can. Check your plan’s summary description before taking a long leave or changing careers.
How Your Monthly Check Is Calculated
The payment comes from a formula, not an account balance. Most pension formulas use three inputs:
- Years of service: the total qualifying years you worked for the employer.
- A benefit multiplier: usually between 1 and 2 percent, applied for each year of service.
- Final average salary: typically the average of your highest three to five years of pay, though some plans average your entire career.
Multiply your years of service by the multiplier, then apply that percentage to your final average salary. An employee retiring after 30 years with a 1.5 percent multiplier and a $70,000 final average salary would get 30 × 1.5% = 45 percent of $70,000, or $31,500 per year — roughly $2,625 per month.3U.S. Department of Labor. Types of Retirement Plans
That amount is locked in for life. It won’t fall with the stock market, and it won’t run out. In most private-sector plans, it also won’t grow with inflation.
Retiring Early
Many plans let you start collecting before the normal retirement age, often 65, but your monthly benefit will be permanently reduced. The logic is simple: if payments run for more years, each check is smaller. Reductions of 5 to 7 percent per year of early retirement are common. Someone retiring five years early might see monthly income cut by 25 to 35 percent compared with waiting to normal retirement age. The exact schedule is in your plan’s summary.
How You Get Paid at Retirement
When you reach retirement age, you’ll choose how to receive your benefit, and the choice is permanent.
- A joint and survivor annuity pays you a monthly amount for life, and after your death a reduced payment (often 50 or 75 percent) continues to your surviving spouse for life. It’s the default for married participants.
- A single-life annuity pays a higher monthly amount, but all payments stop when you die. If you’re married and want this option, your spouse must give written consent, witnessed by a plan representative or notary.
- Some plans offer a lump sum, letting you take the entire present value of future payments as a single check. You gain control and take on all the longevity and investment risk.
Federal law makes the joint and survivor annuity the default specifically to protect spouses who could otherwise be left with no income.4Office of the Law Revision Counsel. 29 U.S. Code 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity Waiving it requires spousal sign-off so one partner can’t make that choice alone.
How the Money Is Taxed
Pension payments are taxed as ordinary income in the year you receive them. Your plan administrator withholds federal income tax from each monthly check, and you’ll receive a Form 1099-R each January documenting the prior year’s distributions. Your total taxable income places pension payments in the same federal brackets as wages. For 2026, rates run from 10 percent on the first $12,400 of taxable income for single filers to 37 percent on income above $640,600.5Internal Revenue Service.

Early Distribution Penalty
If you receive pension distributions before your plan’s normal retirement age or age 65, you may owe an additional 10 percent early withdrawal tax on top of regular income tax.6Internal Revenue Service. Hardships, Early Withdrawals and Loans An important exception applies if you separate from service during or after the year you turn 55. Distributions from that employer’s plan are then exempt from the 10 percent penalty. For public safety employees, the age drops to 50.7Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
Rolling Over a Lump Sum
If you take a lump sum, you can defer the tax bill by rolling the money directly into an IRA or another eligible retirement plan. A direct rollover, where funds move plan to plan without passing through your hands, avoids mandatory 20 percent withholding. If the distribution is paid to you instead, you have 60 days to deposit it into an IRA before the full amount becomes taxable.8Internal Revenue Service. Topic No. 412 Lump-Sum Distributions Missing the 60-day window is one of the most expensive mistakes retirees make.
Required Minimum Distributions
You can’t leave pension money untouched indefinitely. Federal law requires distributions to begin by a certain age. For people born between 1951 and 1959, distributions must start in the year you turn 73. If you were born in 1960 or later, the starting age is 75. Your first distribution must be taken by April 1 of the year after you reach that age, and every subsequent distribution by December 31 each year.9Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
Waiting until that April 1 deadline for the first distribution creates a tax trap: you’ll take two distributions in the same calendar year, which can push you into a higher bracket. The penalty for missing a required distribution is an excise tax of 25 percent of the shortfall, dropping to 10 percent if corrected within two years.10Office of the Law Revision Counsel. 26 USC 4974 – Excise Tax on Certain Accumulations in Qualified Retirement Plans
What Inflation Does to a Fixed Check
Most private-sector pensions pay a fixed dollar amount for life with no automatic adjustment for inflation. Social Security adjusts annually; the 2026 cost-of-living increase is 2.8 percent.11Social Security Administration. Cost-of-Living Adjustment Information Many government pension plans include similar adjustments. In the private sector, that’s the exception.
A $2,625 monthly check that feels comfortable at 65 buys noticeably less at 80. Retirees who rely heavily on a fixed pension without supplemental savings or Social Security to offset inflation see their purchasing power erode steadily.
What Happens If the Plan Fails
Because the employer promises a specific future payout, actuaries calculate the required contributions using assumptions about life expectancy, investment returns, interest rates, and turnover. The money sits in a dedicated trust that is legally separate from the company’s operating funds. Even if the company goes bankrupt, creditors cannot reach pension trust assets.12Office of the Law Revision Counsel. 29 U.S. Code 1103 – Establishment of Trust
Most private-sector plans carry a second layer of protection through the Pension Benefit Guaranty Corporation, a federal agency that guarantees benefits when plans fail.13Office of the Law Revision Counsel. 29 USC 1302 – Pension Benefit Guaranty Corporation If your employer’s plan becomes insolvent, the PBGC steps in and continues paying up to a maximum. For 2026, that maximum is $7,789.77 per month for a worker retiring at age 65 under a straight-life annuity. The cap drops for younger retirees and for joint-and-survivor options.14Pension Benefit Guaranty Corporation. Maximum Monthly Guarantee Tables
You don’t have to take your employer’s word for the plan’s health. Plan administrators must send participants an Annual Funding Notice each year reporting the plan’s funding percentage, its assets and liabilities, and whether contributions are keeping pace with obligations.15U.S. Department of Labor. Field Assistance Bulletin 2025-02 A steadily dropping funded status is worth paying attention to, even with PBGC insurance as a backstop.
