The prevalence of 401(k) plans and IRAs over pensions shifted investment risk from employers to employees

401(k) plans and pensions differ in who has control over the investments

With pension plans, a company contributes to an investment fund from which it distributes regular payments to a retired worker until their death. A 401(k) gives the worker control over contributions in a tax-advantaged account.

US pension plan adoption has declined from 1975 to 2021

Pension plans are a form of guaranteed retirement plan for long-time workers, and they were a major part of industries in the mid-20th century. With the rise of the 401(k) and similar tax-advantaged, defined-contribution accounts, these so-called defined-benefit plans have declined in use by employers. Compare US adoption of both kinds in this table.

Roughly 70 million Americans have 401(k) plans

Ted Benna, a rural benefits consultant, proposed a reinterpretation of a small tweak to the Internal Revenue Code in 1980. This led to a fundamental transformation of how American workers plan for retirement.

Technically speaking, a 401(k) is a type of pension

The Employee Retirement Income Security Act of 1974 lumped both defined-contribution plans like 401(k) plans, and defined benefit plans (like what is colloquially known as a pension) under the term “pension” in order to protect workers and make retirement plan enforcement simpler.

IRAs and 401(k) plans both help individuals save for retirement, but have their differences

Anyone can open an IRA, but 401(k) plans are accessible only through an employer. These two retirement vehicles also have different contribution limits per year, with 401(k) plans allowing you to contribute significantly more than an IRA.

Pension plans investing over 60% in stocks had the highest real returns in 2024

In order to ensure that retirees received all the retirement funds a company or other institution may have promised them, pensions were often limited to investing in run-of-the-mill assets like government securities, investment-grade bonds, and blue-chip stocks. But as market conditions have evolved, pensions are increasingly being invested in a wider range of assets, including alternative investments.

The 401(k) is limited in its ability to provide guaranteed retirement income

Part of the problem is the high, often hidden fees associated with the accounts and a lack of access. Plus, analysts say the annual cost in tax revenue to the government is more than $100B.

A 401(k) plan allows workers to save for retirement without paying taxes until later

With a 401(k) plans you can invest more money now and let it grow with compound interest. Americans have more than $7T invested in these types of accounts.

Roth 401(k) plans vs regular 401(k) plans

A normal 401(k) defers tax payments to later, while a Roth requires no tax payments at withdrawal time. Financial experts often recommend investing in a Roth 401(k) plan or Roth IRA when someone first starts their career to lock in a relatively low tax rate.

Some people roll their 401(k) into an IRA to have more control over their account

However, some argue that you could end up paying less money to invest in a 401(k) plan than you would to invest in an IRA. This article offers a list of pros and cons regarding rolling a 401(k) into an IRA.

Fees can eat away at your 401(k)

Every investment plan has an expense ratio—a percentage of the total assets that goes to the investment manager in the form of fees. Because 401(k) plans are so common, and many of their participants are not savvy investors, the relative expense ratio for them has often excessively increased.

Some multibillion-dollar pension funds depend on hedge funds

Pensions are responsible for safeguarding the retirement plans of many corporate and government employees alike. Pensions differ from 401(k) plans and sometimes rely on alternative assets, like hedge funds, to insulate their portfolios of billions of dollars from volatility in financial markets.

Roth IRAs were first introduced in the Taxpayer Relief Act of 1997

The Roth IRA is one of the most popular retirement accounts in the US. Nearly a quarter of Americans contributed to a Roth IRA in 2023. But this type of financial account hasn’t been around for that long.

Researchers, experts, and retirees are finding that the 401(k) has left much to be desired

Baby Boomers, once the biggest generation, are now creating the largest wave of retirees in US history. Much of this generation is also the first to retire predominantly on the expectation that their 401(k) plans or similar tax-advantaged accounts performed well in the markets—which isn’t always the case.

The financial crisis in 2008 had a major impact on many 401(k) plans

Amid the 2008 financial crisis, stocks and bonds cratered as the broader market floundered due to the subprime mortgage crisis. Investors with so-called "target-date" funds—which shift allocations based on the maturation of a fund—shared in the slump, with some funds declining by 20% or more just a year or two away from maturation.

If your job doesn’t offer a 401(k), you still have retirement savings options

Do you know more than a third of working adults aren't offered a 401(k) through their jobs? If you're part of that group, you still have options for retirement savings, including IRAs, taxable investment accounts, and more.

About 98% of companies offering employees a 401(k) plan match employee contributions

Broadly speaking, an employer 401(k) match means that if you invest money into your 401(k), your employer will put cash in, too. But these programs are often fairly nuanced.

In 2019, Congress passed the Secure Act to reform key aspects of the US tax code

Key Secure Act provisions included raising the age at which mandatory distributions take effect (to increase saving), allowing larger catch-up contributions for older individuals, and allowing employers to directly match contributions in a Roth 401(k).

A work-free retirement is a relatively recent development in human history

Read how Vanguard's founder used the S&P 500 to revolutionize retail investing

John Bogle, the founder of The Vanguard Group, created a fund that tracked the S&P 500 in 1976. That fund created an unprecedented opportunity for individual retail investors, brought down fees across the board, and popularized the belief that passive, low-cost index fund investments would outperform actively managed portfolios long-term.

Should companies be owned by their workers?

In the last half-century, so-called private equity has transformed industries by purchasing private companies, cutting costs, loading up debt, and then selling the business at a premium—all at a huge profit to the investors. Workers, on the other hand, are often left with nothing. Listen to how both pro-worker economists and a private equity stalwart are trying to shift ownership to workers—a growing tactic proven to improve worker satisfaction and company value.

Since the 1990s, banks have sold some of the credit risk of their accounts to external investors, known as SRTs, or synthetic risk transfers

This means if the account defaults, the outside investors assume most of the risk in return for some regular payments, freeing up the bank's ledger. It is a form of insurance used by banks to allow them to free up capital. In 2024, nearly $100B worth of SRT notes were sold.
