The Public Pension Most Workers Undervalue

Picture two people retiring on the same day. The first has $1.2 million in a 401(k) and checks the market every morning with a knot in her stomach. The second has a public pension. On the first of every month, a check arrives, the same size no matter what the market did, and it will keep arriving for the rest of her life.

On paper, the first person looks richer. In practice, they own almost the same thing. A public pension is one of the most valuable assets a working family can hold, and most people who have one have no idea what it is worth. They see a deduction on their pay stub. They should see a seven figure account.

How a defined benefit pension works

Most private sector workers have a defined contribution plan, like a 401(k). What you get at the end depends on how much went in and how the investments did. A public pension is usually a defined benefit plan. Your income is set by a formula, not by the market.

The formula in most plans looks like this: years of service, times a benefit factor tied to your retirement age, times your final compensation. Final compensation is often your highest average pay over one or three years.

Here is an example. Say you retire with 30 years of service, a benefit factor of 2 percent and a final salary of $80,000. That is 30 times 2 percent times $80,000, or $48,000 a year for life. Many plans also add a cost of living adjustment, so the check rises over time.

What a public pension is really worth

To see the real value, ask a simple question: how much money would you need to save to produce the same income yourself?

A common rule of thumb says you can withdraw about 4 percent of a portfolio each year with a good chance it lasts 30 years. Divide $48,000 by 4 percent and you get $1.2 million. That is roughly what the pension in our example replaces. Most of it was funded by employer contributions and decades of investment returns you never had to manage.

The pension also removes a risk most retirees fear. It is called sequence of returns risk. If the market crashes right after you retire, a 401(k) retiree may have to sell investments at low prices to pay the bills. That damage can last for years. A pension retiree does not sell anything. The formula pays the same amount either way.

Think about what that means for your net worth. Most people never count a pension when they add up what they own, because it does not show a balance. But if a $1.2 million portfolio would make you feel wealthy, a pension that replaces it should too. Valuing it correctly changes how you plan the rest of your money.

Some public workers do not pay into Social Security through their job. For years, two federal rules cut Social Security benefits for many of them. The Social Security Fairness Act, signed in January 2025, ended those reductions. If you also have Social Security credits from other work, check your record at ssa.gov.

The hidden cost of leaving too early

The pension formula rewards staying. Because years of service and final salary multiply each other, the value grows fastest in the later years of a career.

Compare two workers. One leaves after 10 years with a final salary of $60,000. At a 2 percent factor, that is $12,000 a year. The other stays 30 years and leaves at $80,000, which is $48,000 a year. Three times the years produced four times the income.

Before you leave any public job, learn three things: your vesting date, which in many plans is five years of service; what happens if you take a refund, since you often give up the employer share; and whether your system has agreements with other public systems that let you carry service credit with you.

Pairing your pension with a 457(b)

The pension is the foundation. A 457(b) deferred compensation plan is the second floor, and it is one of the most underused tax shelters in the country.

• You can contribute pre tax money, which lowers your taxable income now. Many plans also offer a Roth option.
• With a governmental 457(b), there is no 10 percent early withdrawal penalty once you leave the job, at any age. A 401(k) usually charges that penalty before age 59 and a half.
• The 457(b) has its own contribution limit. If your employer also offers a 403(b) or 401(k), you can contribute the full amount to both.
• Many plans allow a special catch up in the three years before your normal retirement age, which can let you save up to double the usual limit.

The IRS sets the yearly limit, and it usually matches the 401(k) limit. A guaranteed pension plus a fully funded 457(b) gives you a floor the market cannot touch and a flexible account you control.

What to do this week

• Find your latest annual pension statement and write down your years of service and projected benefit.
• Run the formula yourself using your plan's benefit factor, so the number feels real.
• Look up your vesting date and whether your plan lets you buy additional service credit.
• Enroll in your 457(b), or raise your contribution by 1 percent of your pay.
• Create a my Social Security account at ssa.gov and review your earnings record.

The market does not touch the formula.

Time does the heavy lifting.

Stay long enough to let it.
