Retiring at 55 — Frequently Asked Questions

Is Classic or PEPRA better?▾
Classic formulas generally produce larger pensions at the same age and service because their benefit factors are higher and they use a 12-month final compensation period instead of 36 months. You don't get to choose — your hire date and prior CalPERS membership determine which set of formulas you fall under. PEPRA members hired on or after 1/1/2013 also contribute more of their own salary toward their pension.
What is a replacement rate?▾
The replacement rate is the percentage of your final compensation that your pension replaces. For example, a 2% benefit factor with 30 years of service gives you a 60% replacement rate, meaning your pension would be 60% of your final compensation.
Am I in CalSTRS or CalPERS?▾
If you are a certificated K-12 teacher, community college instructor, or certain administrator, you are likely a CalSTRS member. Most other California public employees — including school classified staff, state workers, and city/county employees — are CalPERS members. Some careers (e.g., switching from teaching to administration) may build credit in both systems; reciprocity rules then apply at retirement.
Can I retire before the minimum retirement age?▾
Not for service retirement. If you separate from CalPERS-covered employment before reaching your formula's minimum retirement age, you can leave your contributions on deposit and begin drawing your pension once you reach the minimum age. Disability retirement has different rules. Service retirement requires at least 5 years of credit and reaching your formula's minimum age.
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.
Which survivor option should I pick?▾
There is no single right answer — it depends on your beneficiary's age, your beneficiary's expected income without your pension, and your own life expectancy. The 100% survivor option costs roughly 12.25% of your monthly check but guarantees your beneficiary the same payment for life. The 50% survivor option costs roughly 6.5% and continues half. The unmodified option pays the most but ends at your death. Run all four side by side in the calculator's survivor selector.
