What Is the California Public Employees’ Retirement System? Full CalPERS Guide

The California Public Employees' Retirement System (CalPERS) is the largest public pension fund in the United States. It provides retirement benefits for California state employees, public school workers, and local government employees. 

How CalPERS Works

CalPERS is a defined benefit pension plan. Your retirement income is based on a formula — not stock market performance. Both employees and employers contribute during employment, and retirees receive guaranteed monthly payments for life.

How Your Pension Is Calculated

Your benefit is based on:

Age Factor × Years of Service × Final Compensation

• Age Factor: Percentage based on retirement age and membership tier

• Service Credit: Total years worked in a CalPERS-covered job

• Final Compensation: Highest salary year or average of last 3 years

Example:

2.0% × 25 years × $80,000 salary = $40,000 yearly pension.

Retirement Eligibility

• Classic Members: Usually eligible at age 50 with 5 years of service

• PEPRA Members (hired after 2013): Usually eligible at age 52 with 5 years of service

Waiting longer to retire usually increases monthly benefits because the age factor rises with age.

Ways to Maximize Your CalPERS Benefit

• Work until reaching the highest age factor

• Increase your final salary before retirement

• Purchase eligible service credit early

• Carefully choose survivor benefit options

• Coordinate benefits with Social Security

Retiree Health Benefits

Many retirees can continue CalPERS health insurance after retirement. Employer contributions toward premiums depend on years of service and employer rules.

Common Mistakes to Avoid

• Retiring too early without comparing long-term income

• Choosing survivor options without understanding consequences

• Forgetting to update beneficiaries

• Ignoring Social Security reductions like WEP

• Delaying service credit purchases
