Updated October 30, 2026. Quick answer: To retire from CalPERS you need to meet an age requirement and a service requirement. The minimum service is five years, or 10 years for a State of California Second Tier member. The minimum age is 50 for members who joined on or before December 31, 2012 and 52 for members who joined on or after January 1, 2013, depending on the formula. Most miscellaneous members hired after January 1, 2013 get the 2% at 62 formula.
The two requirements
CalPERS says: “To retire you must meet two requirements: age and service credit”. “The minimum service requirement is five years, or 10 years if you are a State of California Second Tier member”. On age: “Your minimum retirement age depends on your retirement formula: 50, 52, or 55”.
The minimum age by membership date
The member benefits guide for public agency members says to be eligible for service retirement you must have: “To be eligible for service retirement, you must have at least five years of CalPERS-credited service and be at least age 50 or 52, depending on your retirement formula”. Specifically: “Age 50 if you became a member on or before December 31, 2012 or”. “Age 52 if you became a member on or after January 1, 2013 And have at least 5 years of CalPERS service or have worked part time for at least 5 years”. Members with a mix of both: “If you have a combination of classic and PEPRA service, you may be eligible to retire at age 50”.
The benefit factor
How age enters the pension: “Your benefit factor, also known as “age factor,” is the percentage of pay you’ll receive for each year of service credit earned”. “Starting at your minimum retirement age, your benefit factor increases every quarter year up to a maximum age”. “Most miscellaneous members hired after January 1, 2013, receive the 2% at 62 formula”. In CalPERS’s words: “If your retirement formula is 2% at 62, for example, this means you get 2% of your pay if you retire at age 62”.
What the pension is based on
“Your final compensation is your highest average annual compensation earnable during any consecutive 12-month or 36-month period of employment, depending on your membership date and employer’s contract”.
A worked example with invented numbers
Take an invented 2% at 62 member who retires at age 62 with 30 years of service credit. That is 30 years at 2%, or 60% (computed) of a final average salary of $70,000 (invented, for the computation), which comes to $42,000 a year (computed).
What the documents do not say
Neither document read prints a reduction rule in prose: the benefit factor by age sits in CalPERS’s benefit factor charts, which are tables and are not quoted here. Vesting is not defined separately, only the five-year (10-year Second Tier) service minimum to retire. State Second Tier, safety and state member formulas, and other classic formulas are not worked through.
Common mistakes
- Treating the minimum retirement age as the age of the full benefit. For the 2% at 62 formula the 2% factor applies at 62, and a younger retiree gets a smaller factor.
- Using age 50 for a member who joined on or after January 1, 2013. The guide says 52.
- Assuming five years of service is the vesting rule. CalPERS’s pages describe it as the minimum service to retire.
