Employee Contributions
 

For the vast majority of employees of state and local government, participation in a public pension plan and contributing toward the cost of the pension are mandatory terms of employment. Employee contributions provide a reliable and predictable stream of revenue to public pension funds and typically are based on a percentage of salary as specified in statute, most commonly between four and eight percent. More...

Contributions Over Time

Over time, investment earnings finance a majority of the cost of a typical public pension plan. According to the U.S. Census Bureau, for the 30 years 1990 through 2019, investment earnings accounted for 61 percent of public pension revenues; employer contributions made up approximately 27 percent, and employee contributions were around 12 percent.

A recent study, Pensionomics 2016: Measuring the Economic Impact of DB Pension Expenditures, finds that pension benefits have a significant economic impact: 7.1 million American jobs and $1.2 trillion in economic output. Also, for every taxpayer dollar contributed to state and local pensions $9.19 in total output was supported.
