The California State Teacher Retirement System, known to most people as CalSTRS, is the pension plan that pays retirement income to public school educators across California. If you teach in a California public school, community college, or county office of education, this system holds your future retirement money.
Teacher retirement in California works very differently from a private sector 401(k) plan, and many teachers do not fully understand how it works until they are close to retiring. That is a problem, because a few decisions made early can change your monthly check for the rest of your life. This guide explains the system in plain words, so you know what you have and what you still need to plan for.
What Is the California State Teacher Retirement System?
The teacher retirement system of California was created by law in 1913. It is part of the State of California Government Operations Agency, and it is run by a 12-member Teachers Retirement Board.
Today it serves about 965,000 educators and their families, from prekindergarten teachers through community college instructors. As of June 30, 2025, the fund managed a portfolio worth 367.7 billion dollars. That makes it the largest teachers’ retirement fund in the United States.
The teacher retirement system California educators belong to is not one single plan. It is actually a group of programs working together:
- Defined Benefit Program. This is the main pension. It pays you a set monthly amount for life.
- Defined Benefit Supplement. A cash balance account that builds extra savings on top of the main pension.
- Cash Balance Benefit Program. A separate option built for part-time educators and adjunct faculty.
- CalSTRS Pension2. A voluntary savings plan with 403(b) and 457(b) accounts.
Most of this guide focuses on the Defined Benefit Program, because that is where your California teacher retirement pension comes from.
Who is a CalSTRS Member?
You are covered by the system if you perform creditable service for a California public school employer. That includes school districts, community college districts, county offices of education, and regional occupational programs. Around 1,780 employers participate.
Classroom teachers, librarians, counselors, administrators, and community college faculty are all typically covered.
One important note. Not every school employee is in CalSTRS. Classified staff such as bus drivers, custodians, and office workers usually belong to CalPERS instead. The two systems have different rules, so it matters which one you are in.
The California Teacher Retirement Formula Explained
Your pension is not based on how much money you put in. It is based on a formula set by state law.
The California teacher retirement formula is:
Service credit × age factor × final compensation = your monthly retirement benefit
Here is what each piece means:
- Service credit is the number of full and partial school years you worked and contributed to CalSTRS. Unused sick leave can add to this at retirement. Your employer reports your unused sick days, and CalSTRS converts them into extra service credit.
- Age factor is a percentage based on your age on the last day of the month in which you retire. The older you are when you retire, the higher this number goes.
- Final compensation is your highest average annual compensation over a set period, either 12 or 36 consecutive months, depending on your situation.
A simple example helps. A teacher with 25 years of service credit, a 2 percent age factor, and 8,000 dollars a month in final compensation would get 25 × 0.02 × 8,000, which is 4,000 dollars a month for life.
Two Benefit Structures: 2% at 60 and 2% at 62
This is the single most important thing to understand about your teacher retirement plan California membership. There are two different benefit structures, and the one you fall under depends entirely on your hire date.
CalSTRS 2% at 60 covers members first hired to perform creditable service on or before December 31, 2012.
CalSTRS 2% at 62 covers members first hired on or after January 1, 2013. This structure came from the California Public Employees Pension Reform Act, usually called PEPRA.
The differences are significant:
| Feature | 2% at 60 | 2% at 62 |
| Standard age factor | 2% at age 60 | 2% at age 62 |
| Lowest age factor | 1.1% at age 50 | 1.16% at age 55 |
| Maximum age factor | 2.4% at age 63 | 2.4% at age 65 |
| Earliest retirement | Age 55 with 5 years, or age 50 with 30 years | Age 55 with 5 years |
| Career factor bonus | Yes, 0.2% with 30+ years | No |
| Final compensation period | 12 months with 25+ years, else 36 months | Always 36 months |
Members under 2% at 60 who retire with 30 or more years of service credit get a career factor. CalSTRS adds 0.2 percent to the age factor, up to the maximum of 2.4 percent. Members under 2% at 62 do not get this.
There is also a cap on how much compensation counts toward the benefit for 2% at 62 members. The cap was 182,266 dollars for the 2024 to 2025 fiscal year and adjusts each year with inflation.
The practical result is that newer teachers generally need to work longer to reach the same benefit level. CalSTRS has estimated that the pension replaced about 54 percent of final salary for members who retired before PEPRA, and expects roughly 47 percent for members under the newer structure.
California Teacher Retirement Age: When Can You Retire?
This is one of the most searched questions among educators, so let us be precise about it.
The minimum California teacher retirement age depends on your benefit structure.
If you are under 2% at 60, you can retire at age 55 with at least five years of service credit. You can also retire as early as age 50 if you have at least 30 years of service credit.
If you are under 2% at 62, you can retire at age 55 with at least five years of service credit. The age 50 option is not available to you.
So the short answer to when a teacher can retire in California is age 55 for most members, with a limited age 50 path for longer-serving members hired before 2013.
But being eligible and being ready are two different things. Retiring at the minimum teacher retirement age in California means accepting a much smaller age factor. A 2% at 60 member who retires at 50 gets a 1.1 percent age factor instead of 2.4 percent at 63. That difference cuts the monthly pension by more than half for the same years of service.
Working a few extra years often raises the benefit in three ways at once. You add service credit, you raise your age factor, and you usually raise your final compensation. If you are weighing an early exit, our retirement planning services can help you compare the numbers side by side before you commit.
California Teacher Retirement Benefits Beyond the Pension
The monthly pension is the centerpiece, but the full range of California teacher retirement benefits includes more.
- Disability benefits are available if you can no longer perform your job. Coverage A and Coverage B have different rules depending on when you became a member.
- Survivor benefits pay your family if you pass away before or after retirement. Keeping your Recipient Designation form current is important, and many members forget to update it after a marriage, divorce, or death in the family.
- Defined Benefit Supplement account. For 2% at 60 members, you and your employer each contribute 8 percent of certain earnings above one year of service credit. For 2% at 62 members, you contribute 9 percent, and your employer contributes 8 percent. This money sits in a separate account, and you can take it as a lump sum or annuity.
- Pension2 lets you save more through tax-advantaged payroll deductions in a 403(b) or 457(b). Because the pension alone replaces only about half of a typical final salary, this extra layer matters more than most teachers realize.
- Long-term care. As a CalSTRS member, you and certain family members may be eligible for the CalPERS Long Term Care Program.
California Teacher Retirement Health Benefits: The Gap Most Teachers Miss
This section deserves careful attention, because the answer surprises many educators.
CalSTRS does not provide health or dental insurance.
Unlike CalPERS, which runs a large health program, CalSTRS is a pension system only. Health coverage for teachers is negotiated locally through collective bargaining with your school district.
Under California Education Code sections 7000 through 7008, districts, community colleges, and county offices of education must offer retiring CalSTRS members and their spouses or registered domestic partners the chance to continue medical and dental coverage. But here is the catch. They must offer you the opportunity to continue coverage at your own cost. They are not required to pay for it.
Every district handles California teacher retirement health benefits differently. Some districts pay a generous share of retiree premiums. Some pay a small amount for a limited number of years. Many pay nothing at all, leaving the retiree to cover the full premium.
If you plan to retire before age 65, this can be the single largest expense in your retirement budget. Medicare does not start until age 65, so you may face several years of paying full price for coverage.
There is one program worth knowing. The CalSTRS Medicare Premium Payment Program can pay Medicare Part A hospital premiums for eligible retired members. Eligibility is narrow. It applies to members who retired on or after January 1, 2001, from a district that completed a Medicare Division before their retirement date.
The action step is simple. Contact your district benefits office now, not in your final year, and ask exactly what you will receive in retirement. Then build that number into your plan.
CalSTRS and Social Security: What Changed
Most California public school educators do not pay into Social Security for their CalSTRS-covered work. That means you generally do not earn Social Security credits from teaching.
For decades, two federal rules made this worse for teachers who had other jobs. The Windfall Elimination Provision reduced Social Security benefits earned in other covered work. The Government Pension Offset cut spousal and survivor benefits by two-thirds of the CalSTRS pension amount, which often wiped them out completely.
Both rules are now gone.
The Social Security Fairness Act was signed into law on January 5, 2025. It repealed the Windfall Elimination Provision and the Government Pension Offset, effective for benefits payable after December 2023.
For a retired teacher, this change can be worth a great deal. A teacher whose survivor benefit was previously reduced to zero by the offset may now receive the full amount. Retroactive payments were also issued to affected retirees.
If you retired before 2025 and never applied for spousal or survivor benefits because the offset would have eliminated them, it is worth contacting the Social Security Administration to check your eligibility again. Many teachers never applied and do not realize that the rules have changed.
Are CalSTRS Pensions Taxed?
Yes. Your CalSTRS contributions are taken out before taxes, so you owe income tax when the money comes back to you as a pension.
At the federal level, your monthly benefit is taxed as ordinary income. CalSTRS sends you a Form 1099-R each January showing the taxable amount.
At the state level, California taxes pension income at the same rates as regular income, which run from 1 percent up to 13.3 percent. There is no special exclusion for teacher pensions. For a fuller picture of how the state treats different retirement income sources, see our guide on whether California taxes retirement income.
One planning note. If you move out of California after you retire, your CalSTRS pension is generally taxed by your new state of residence, not by California. Several states do not tax pension income at all. This is a real factor for teachers considering a move, and it is worth reviewing with a CPA before you relocate. Our tax planning services cover exactly this kind of multi-year decision.
Using a Teacher Retirement California Calculator
CalSTRS provides a Retirement Benefits Calculator through your myCalSTRS account. It uses your actual service credit and salary data, which makes it far more accurate than a generic teacher retirement calculator you might find elsewhere online.
Run it more than once. Try different retirement dates and see how the number moves. Most teachers are surprised by how much one extra year adds, especially if that year crosses an age factor threshold like 60, 62, 63, or 65.
You should also check your Retirement Progress Report each year. It lists your service credit and reported earnings. Errors do happen, and they are far easier to correct while you are still working than after you file for retirement.
What the calculator will not tell you is whether the resulting income is actually enough. It does not know your health premiums, your mortgage, your tax bracket, or your other savings. That gap between the pension estimate and a real budget is where planning work happens.
Working After Retirement
Many educators return to part-time work after they retire. There are rules you must follow.
You cannot earn pay for the first 180 calendar days after your retirement date without affecting your benefit, unless a narrow exemption applies.
There is also an annual earnings limit on work in CalSTRS-covered positions. That limit was temporarily raised for the 2024 to 2025 and 2025 to 2026 fiscal years, and the law reverted to the prior standard after June 30, 2026. If you are planning post-retirement work, confirm the current limit before you accept an assignment.
Going over the limit reduces your retirement benefit dollar for dollar, so this is worth checking carefully.
Planning Around Your Pension
A CalSTRS pension is a strong foundation, but it is rarely the whole plan. Three gaps come up again and again.
- The first is the replacement ratio. If your pension replaces around half of your final salary, you need other income to close the difference. Pension2, a personal IRA, or taxable savings can all fill that space.
- The second is health coverage before 65, which we covered above.
- The third is tax diversification. Everything in your CalSTRS pension and your 403(b) comes out as taxable income. Having some money in a Roth account gives you flexibility to manage your bracket in retirement.
For educators who also run a side business, tutoring practice, or consulting work, there are additional structures worth exploring. A California private retirement plan is one option that can offer both asset protection and additional retirement savings outside the state system. Our financial consulting services can help you look at how these pieces fit together.
Frequently Asked Questions
What is the earliest age a California teacher can retire?
Age 55 with five years of service credit for most members, or age 50 with 30 years for those hired on or before December 31, 2012.
How is the CalSTRS pension calculated?
Service credit multiplied by your age factor multiplied by your final compensation equals your monthly lifetime benefit.
Does CalSTRS provide health insurance in retirement?
No, CalSTRS does not offer health or dental coverage. Retiree health benefits are negotiated separately by each school district.
Do California teachers get Social Security?
Not from CalSTRS-covered work, but benefits earned in other jobs are no longer reduced since the Social Security Fairness Act took effect.
Is a CalSTRS pension taxable?
Yes, it is taxed as ordinary income at both the federal level and by California, since contributions were made before tax.
Final Thoughts
The California State Teacher Retirement System gives educators something increasingly rare, which is a guaranteed monthly income for life. But the pension was never designed to cover everything on its own, especially with health coverage left to individual districts and a replacement ratio of nearly half of final pay. Knowing your benefit structure, your age factor, and your real health costs well before you retire is what turns a good pension into a comfortable retirement.
