Should I Retire at 55 or 57?

Two extra years of work — what they buy

The answer depends almost entirely on your formula. For Classic miscellaneous members on the 2% at 55 formula, age 55 is already the reference age — the benefit factor is at its full 2.000% there. Working two more years to 57 still helps (more service credit, and the factor keeps creeping upward), but the marginal gain is mostly from extra years of service, not from the factor.

For PEPRA safety members on 2.7% at 57, it's the opposite story: 55 is well below the reference age, so the factor is still climbing steeply. Two more years to 57 finishes the climb to the full 2.7% factor and adds service credit. The marginal benefit of waiting is much larger.

Retire at 55

$4,000

monthly · 25 years

Benefit factor: 2.000%

Retire at 57

$4,592

monthly · 27 years

Benefit factor: 2.126%

Difference: $592/month ($7,106/year). The two extra years buy you about 15% more monthly pension for life — but you also forgo two years of pension payments ($96,000 at the age-55 rate) that you would have been collecting between ages 55 and 57.

Above shows the 2% at 55 Classic State Misc formula. For safety members, the same comparison on 2.7% at 57 produces a much wider age-55-vs-age-57 spread because 55 is still well below the reference age there.

Retire at 55 or 57? — Frequently Asked Questions

Does CalPERS affect my Social Security benefits?▾
Some CalPERS formulas are Social Security covered, meaning you pay into both CalPERS and Social Security. Others are not covered, meaning you do not pay Social Security taxes and may be subject to the Windfall Elimination Provision (WEP) if you have Social Security credits from other employment.
What is the difference between Classic and PEPRA?▾
Classic members were hired before January 1, 2013, or had existing CalPERS membership. PEPRA (Public Employees' Pension Reform Act) members were hired on or after January 1, 2013, with no prior CalPERS membership. PEPRA formulas generally have lower benefit factors at younger ages but the same or similar factors at older retirement ages.
What is the difference between CalSTRS and CalPERS?▾
CalSTRS (California State Teachers' Retirement System) covers certificated K-12 teachers, community college instructors, and some administrators. CalPERS (California Public Employees' Retirement System) covers state, school, and local public agency employees. Teachers may have benefits from both systems depending on their career.
What are the survivor benefit options?▾
CalPERS offers four retirement options: Unmodified (no survivor benefit, highest monthly payment), 100% Survivor (your beneficiary receives the same monthly benefit after your death), 75% Survivor, and 50% Survivor. Choosing a survivor option reduces your monthly pension. The reduction depends on your age and your beneficiary's age at retirement.
What is final compensation?▾
Final compensation is the average of your highest salary over a specific period, typically your highest 12 or 36 consecutive months depending on your formula. PEPRA members use a 36-month average; classic members typically use a 12-month average.
When can I retire from CalPERS?▾
You can retire when you reach the minimum retirement age for your formula and have at least 5 years of service credit. However, retiring at the minimum age typically gives you a much lower benefit factor. The benefit factor increases as you approach and reach your formula's reference age.
