What Is a Defined Benefit Plan?

A defined benefit plan is a type of employer-sponsored retirement plan that promises a specified monthly benefit to employees upon retirement. This predetermined payout is typically based on a formula that considers factors such as an employee's salary history, years of service with the company, and age at retirement. Unlike other retirement savings vehicles, the employer bears the investment risk and responsibility for ensuring sufficient funds are available to pay the promised pension plans annuity or lump sum distribution¹⁷. This type of plan falls under the broader financial category of retirement planning and employee benefits.

History and Origin

Defined benefit plans have a long history, with early forms of pensions emerging in the late 19th and early 20th centuries, often in large industrial companies and unionized sectors. However, a significant turning point for these plans in the United States came with the passage of the Employee Retirement Income Security Act (ERISA) of 1974. This landmark federal law was enacted to protect the interests of participants in private-sector employee benefit plans. Prior to ERISA, instances such as the Studebaker pension fund default in 1963 highlighted the risks employees faced, as many were left without their promised benefits when companies failed¹⁶.

ERISA established minimum standards for participation, vesting, funding, and fiduciary duty for private pension plans. It also created the Pension Benefit Guaranty Corporation (PBGC), a federal agency designed to insure defined benefit plans and provide a safety net for retirees if a plan terminates without sufficient assets¹³, ¹⁴, ¹⁵. While intended to strengthen defined benefit plans, some experts argue that the increased regulatory burden and complexity introduced by ERISA contributed to their decline in the private sector in subsequent decades¹¹, ¹².

Key Takeaways

• A defined benefit plan guarantees a specific retirement benefit, often a monthly payment, to eligible employees.
• The employer is responsible for funding the plan and bears the associated investment risk.
• Benefit amounts are typically determined by a formula considering salary, years of service, and age.
• The Pension Benefit Guaranty Corporation (PBGC) insures private-sector defined benefit plans, providing a safety net for participants.
• Defined benefit plans have largely shifted from the private sector to the public sector in recent decades.

Formula and Calculation

The benefit provided by a defined benefit plan is typically calculated using a specific formula outlined in the plan document. While the exact formula varies, a common structure might look like this:

Benefit = (( \text{Years of Service} \times \text{Final Average Salary} \times \text{Benefit Multiplier} ))

Where:

• Years of Service: The total number of years an employee has worked for the company while participating in the plan.
• Final Average Salary: Often the average of the employee's highest consecutive three or five years of earnings, or sometimes the average over their entire career.
• Benefit Multiplier: A percentage set by the plan, for example, 1.5% or 2%.

For example, a plan might promise an annual benefit equal to 1.5% of the employee's final average salary multiplied by their years of service.

The employer's contributions to the plan are determined through complex actuarial analysis. Actuaries forecast future benefit payments, considering factors such as employee demographics, projected salaries, and expected investment returns, to calculate the required annual contributions needed to fund the promised benefits. The Internal Revenue Service (IRS) sets limits on the annual benefits that can be provided by defined benefit plans¹⁰.

Interpreting the Defined Benefit Plan

For an employee, a defined benefit plan offers a predictable stream of retirement income, which can provide significant financial security. The primary interpretation for a participant revolves around understanding the benefit formula and how their years of service and salary will translate into a future payout. Employees typically do not need to make asset allocation decisions or manage investment risk within these plans, as that responsibility falls on the employer or plan administrator. Understanding the vesting schedule is also crucial, as it determines when an employee's right to the promised benefit becomes non-forfeitable.

Hypothetical Example

Consider an employee, Sarah, who has worked for Company X for 30 years and is about to retire. Company X offers a defined benefit plan with the following formula: 1.5% of final average salary multiplied by years of service. Sarah's final average salary (calculated as the average of her highest five consecutive years of earnings) is $80,000.

Using the formula:
Annual Benefit = 30 Years of Service × $80,000 Final Average Salary × 0.015 Benefit Multiplier
Annual Benefit = $36,000

Upon retirement, Sarah would be eligible to receive an annual pension of $36,000 for the rest of her life, or potentially a monthly payment of $3,000. This example illustrates how the fixed formula provides a clear and predictable benefit. The company is responsible for ensuring the plan has sufficient assets to pay this benefit, regardless of market fluctuations.

Practical Applications

Defined benefit plans are a core component of retirement planning, providing a guaranteed income stream for retirees. They are commonly found in government employment, unionized environments, and some legacy corporate plans. ⁹Employers can often make substantial tax deductions for their contributions to these plans.

The Pension Benefit Guaranty Corporation (PBGC) plays a critical role in the practical application of defined benefit plans in the private sector. Established by the Employee Retirement Income Security Act of 1974, the PBGC's mission is to protect the retirement security of millions of Americans by guaranteeing pension benefits up to certain limits, even if the sponsoring employer's plan fails. ⁶, ⁷This provides a vital layer of security that distinguishes defined benefit plans from other retirement savings vehicles where participants bear more individual risk.

Limitations and Criticisms

While offering security, defined benefit plans have several limitations and have faced criticisms, leading to their decline in the private sector. One major criticism for employers is the significant administrative burden and financial liability associated with managing these plans. Employers bear the full investment risk and longevity risk (the risk that retirees live longer than expected), which can lead to unpredictable and potentially very large funding requirements, especially in periods of poor market performance or rising life expectancies. ⁵This contrasts with defined contribution plans, where the employee generally bears the investment risk.

For employees, a key limitation can be the lack of portability. Benefits in a defined benefit plan typically do not increase in value once an employee leaves a firm, and frequent job changes can result in several small, non-growing annuities upon retirement, unlike a portable defined contribution plan where funds can continue to grow. ⁴The stringent IRS regulations and the complexities of compliance can also make defined benefit plans costly and cumbersome for employers to establish and maintain, particularly for smaller businesses.

Defined Benefit Plan vs. Defined Contribution Plan

The primary distinction between a defined benefit plan and a defined contribution plan lies in who bears the investment risk and how the retirement benefit is determined.

Confusion often arises because both are types of employer-sponsored retirement plans. However, the fundamental difference lies in the "definition" of the plan: a defined benefit promises a specific payout, while a defined contribution specifies the contributions made into an individual account.

FAQs

What does "defined benefit" mean?

"Defined benefit" refers to the fact that the retirement benefit an employee will receive is clearly defined or predetermined by a formula, typically based on their salary, years of service, and age.

Are defined benefit plans still common?

Defined benefit plans have become less common in the private sector, largely replaced by defined contribution plans like 401(k)s. However, they remain prevalent in the public sector for government employees and in some unionized industries.
¹

Who manages the investments in a defined benefit plan?

The employer, or a third-party administrator hired by the employer, manages the asset management and investments of a defined benefit plan. Employees do not typically make investment decisions within these plans.

Is a defined benefit plan guaranteed?

Private-sector defined benefit plans are insured by the Pension Benefit Guaranty Corporation (PBGC) up to certain limits, providing a federal guarantee for a portion of the promised benefits if the plan becomes underfunded or terminates. Public sector plans (for government employees) are not covered by the PBGC but are typically backed by the government entity itself.

How are defined benefit plans funded?

Defined benefit plans are funded primarily by employer contributions. These contributions are calculated by actuaries to ensure that there will be enough money in the plan's trust to pay all future promised benefits. The funding levels are subject to strict regulations and ongoing risk management oversight.
