Defined Pension Plan: An Overview

defined pension plan

A pension is a promise of a specified monthly benefit upon retirement, which can either be set by a formula involving years of service and final pay or by a defined amount. One of the most reliable and traditional forms of post-retirement income, the defined pension plan has been a cornerstone for many workers over the past century. In this article, we will delve into the specifics of what a defined pension plan is, how it works, its advantages and disadvantages, and its current status in the evolving world of retirement planning.

Key Takeaways: Defined Pension Plan

  • Definition: A Defined Pension Plan is a retirement scheme where employers promise a specific lifetime benefit to retirees.
  • Functioning: Benefits are calculated using set formulas, typically involving salary, years of service, and age.
  • Advantages: Offers retirees predictability and security in income, with employers backing the funds.
  • Challenges: They can be costly for employers, inflexible, and less suitable for a mobile workforce.
  • Trend: There’s a notable shift from Defined Pension Plans to defined contribution plans like the 401(k).

What is a Defined Pension Plan?

A defined pension plan, often called a defined benefit (DB) plan, is a retirement plan in which an employer promises to pay a specific benefit to retirees for life. The benefit is typically calculated using a set formula, which often takes into account factors such as the employee’s salary, years of employment, and age at retirement.

How Does It Work?

  1. Funding: Employers are responsible for making the necessary contributions to fund the defined benefit promises. They usually contribute to a trust that is designated for these pension obligations. Investments within the trust are managed either in-house or by external fund managers.
  2. Benefit Calculation: Most defined pension plans use a formula to determine the monthly benefit. This formula often multiplies the employee’s final average salary by a certain percentage for each year of service.
  3. Payout: Upon reaching the retirement age defined by the plan, the retiree starts receiving the promised benefit, usually on a monthly basis. Some plans also offer a lump-sum payout option.


  1. Predictability: For retirees, the primary advantage is the predictability of income. They know in advance how much they’ll receive upon retirement.
  2. Security: The benefit isn’t dependent on investment performance, offering peace of mind for retirees.
  3. Employer-backed: The onus is on employers to ensure funds are available to meet their pension obligations.


  1. Cost: For employers, funding a defined benefit plan can be expensive, especially if investments don’t perform well or if actuarial assumptions change.
  2. Inflexibility: Defined pension plans can be less adaptable to changes in the workforce or business circumstances.
  3. Limited Mobility: For employees, if they change jobs frequently, they might not stay long enough with one employer to fully benefit from a defined pension plan.

The Current Status and Future of Defined Pension Plans

Over the past few decades, there’s been a shift from defined benefit plans to defined contribution plans, like the 401(k) in the U.S. Several factors have driven this change:

  • Cost Concerns: The financial obligation for employers can be significant, especially with increasing life expectancies and volatile market conditions.
  • Workforce Mobility: The modern workforce changes jobs more frequently, making short-term, portable retirement benefits like the 401(k) more attractive.
  • Shift of Investment Risk: In defined contribution plans, the investment risk shifts from the employer to the employee.

However, despite the decline, many public sector jobs and some large corporations still offer defined pension plans. They remain a valued benefit for those who have access to them, providing a predictable and stable source of retirement income.


Defined pension plans have been a crucial part of the retirement landscape for many years. While they may be less prevalent today, understanding their structure and benefits is essential for anyone planning their retirement or considering job offers with such plans. As with all retirement strategies, it’s wise to consult with financial professionals to make informed decisions.
