Difference Between Pension and Retirement Plan

by Bob Haring
A good pension or retirement plan can let you relax like this.

A pension once was a standard benefit for a lifetime of working, but today only about 20 percent of Americans have them. Many of those are employees of local or federal government agencies, while most workers in private business now have retirement plans. The big difference is in who puts up the money. Employers fund pensions; employees put their own money into retirement plans, although often with some employer contributions.

Benefit or Contribution

A pension is a "defined benefit" program. An employer sets aside money into some investment pool that is used to pay pension benefits to retired employees, usually based on some formula of number of years worked for the company, earnings and age. A retirement plan is a "defined contribution" program in which employees contribute part of their earnings to some investment to be withdrawn at retirement with no guaranteed benefit.

Pension Guarantees

Private pensions are generally protected now by the federal Pension Benefit Guaranty Corp. Companies whose pensions are underfunded, meaning they don't have enough money to guarantee all benefits, pay fees to the PBGC, which then guarantees employees their pensions. Public pensions often are underfunded, but governments guarantee those payments through taxes.

401(k) Plans

The most popular type of retirement plan is a 401(k) for private employers. Nonprofit and educational organizations offer similar plans called 403(b) and 457(b). In these programs, employees have money set aside to be invested and withdrawn after retirement age, which the Internal Revenue Service defines as age 59 1/2. Some of these defer taxes on contributions.

Other Plan Types

Employers may contribute to some defined contribution plans or may create programs like Simplified Employee Pension or Simple Incentive Match Plan for Employees, called SEP and SIMPLE, which are mainly employer-financed. Another form is an employee stock ownership plan or ESOP, in which the retirement funds are invested in a company's stock.


Pensions usually have specific retirement benefits, stated by the employer. An employer may determine eligibility for benefits and how they are paid, for instance. Retirement plans are governed by IRS regulations on withdrawals, but the amount in the fund basically determines the benefit payments. Some employers offer both defined benefit and defined contribution plans.
