Ages are on the last day of your retirement month. The table counts whole years; the factor also rises month by month (see the full age factor table). In CalSTRS 2% at 60, retiring before 55 needs 30 years of service.
The handbook's text says the age factor drops 0.01% for each month you retire before normal retirement age. But its 2% at 60 table drops only 0.005% a month between ages 50 and 55.
We use the table.
p. 78, Age factor tablesThe Reduced Benefit Election (CalSTRS 2% at 60 only)
Age 55 to under 60 with at least five years: receive one-half of the monthly benefit calculated as if you were age 60, for the same number of months after age 60 that you received benefits before 60; then the amount you would have received had you retired at 60. Not available if you previously retired for service or disability, or received a disability benefit. Handbook p. 45, Reduced Benefit Election
For the Reduced Benefit Election the handbook doesn't say whether the career factor is included in the 'as if you were 60' amount.
We include it when you have 30+ years.
p. 45, Reduced Benefit ElectionWhat the handbook says
- You become vested, with a right to a lifetime benefit, at five years of service credit.p. 137, Glossary: Vested
- 2% at 60: you can retire at 55 with at least five years of service credit, or as early as 50 with at least 30 years.p. 20, Eligibility for benefits
- 2% at 62: the earliest you can retire is 55 with five years of service credit. Age 50 with 30 years doesn't apply.p. 20, Eligibility for benefits
- Retiring before normal retirement age (60 or 62) lowers your age factor: for example 1.4% instead of 2% at 55 under 2% at 60, and 1.16% instead of 2% at 55 under 2% at 62.p. 78, Age factor tables
- If you're 55 or older and retire on the same day from CalSTRS and CalPERS (or another listed California system), you may retire with fewer than five years of CalSTRS service. Membership in another system can't be used for the age 50 / 30 years rule or the benefit enhancements.p. 44, Retiring from more than one public retirement system
- Reduced Benefit Election (2% at 60 only): if you're 55 to under 60 with five years, you can take half of the benefit figured as if you were 60, for as many months after 60 as you were paid before 60. After that you get the full age-60 amount.p. 45, Reduced Benefit Election
- Example: Jaime, 57 and five months, with $5,000 final compensation and 25 years, would get $1,250 a month until 62 and seven months, then $2,500.p. 45, Reduced Benefit Election
- After a refund and return, you need at least one year of service credit earned since the most recent refund (and five years in all) before you can retire, unless you retire concurrently from another eligible system.p. 26, Redepositing to restore service credit
- Your retirement date must be after your last day of work, vacation or compensated leave. If it isn't the 1st of a month, your first payment is prorated.p. 44, Choosing your retirement date
- From January 1, 2026, a backdated retirement date can be no earlier than 270 calendar days before CalSTRS receives your application.p. 44, Choosing your retirement date
- Submit your Service Retirement Application no earlier than six months before your retirement date; 10-12 months before, start planning.p. 88, Your CalSTRS retirement timeline
- Check with CalSTRSExact cutoff for the age-55 test: the handbook doesn't say whether eligibility uses your age on the retirement date or at the end of that month (it only says the age factor uses month-end age). Our calculator uses your actual age on the retirement date.p. 44, Choosing your retirement dateNot stated in the handbook.
Questions
How much does CalSTRS reduce my pension if I retire early?
There's no separate penalty. Your age factor is just lower. In CalSTRS 2% at 60, retiring at 55 gives 1.4% per year of service instead of 2% at 60. In CalSTRS 2% at 62, retiring at 55 gives 1.16% instead of 2% at 62. The lower factor lasts for life.
What's the earliest I can retire?
Age 55 with 5 years of service credit in both structures. CalSTRS 2% at 60 members with 30 years can retire at 50.
