Your CalSTRS benefit is driven by three things: your service credit, your age at retirement, and your final compensation. The two decisions that matter most and cannot be undone are which benefit structure you retire under and which survivor option you elect. Both should be modelled before you file, not after.
The two benefit structures
| 2% at 60 | 2% at 62 | |
|---|---|---|
| Applies to members who joined | Before 1 January 2013 | On or after 1 January 2013 |
| Normal retirement age | 60 | 62 |
| Earliest retirement | 55 (reduced) | 55 (reduced) |
| Final compensation period | Highest 12 or 36 months | Highest 36 months |
| Maximum age factor | 2.4% at 63 | 2.4% at 65 |
The formula itself has the same shape for everyone — service credit × age factor × final compensation — so the structure you fall under determines how fast the age factor climbs and which salary period counts. Confirm which structure applies to you in myCalSTRS rather than assuming: members who left and returned to service, and members with prior time in another California system, are the most frequently surprised.
The Defined Benefit Supplement
Alongside the main pension, CalSTRS maintains a Defined Benefit Supplement (DBS) account — a separate pot funded over your career from specific kinds of compensation, with its own balance and its own distribution choices at retirement. It is the closest thing a CalSTRS member has to a "lump sum," and it is routinely confused with the main pension, which works nothing like it. Look up your DBS balance in myCalSTRS, get the current distribution options from CalSTRS directly, and decide how it fits next to everything else rather than in isolation.
Service credit purchases
In certain situations CalSTRS lets you buy service credit — for example redepositing previously withdrawn contributions after a break in service. A purchase raises the years input permanently, so the question is always the same arithmetic: the price CalSTRS quotes, against the permanent monthly increase, over the years you expect to collect, against what the same money would do in your 403(b) or elsewhere. Sometimes excellent value, sometimes not. Get the official quote first; the price is CalSTRS's to set.
Survivor elections are permanent
At retirement you choose between the highest monthly benefit for your life only, and options that reduce your monthly amount in exchange for continuing payments to a beneficiary after your death. The election is, for practical purposes, permanent — and it is the decision educators most want to redo five years later. Whether the reduction is worth it depends on things CalSTRS cannot know: your spouse's own benefits, life insurance in force, the age gap, and the other assets that could carry a survivor. Solve it before the paperwork, with both of you looking at the same numbers.
The 403(b) sold in the staff lounge
Most California educators also carry a 403(b) — and a large share of those accounts were sold, years ago, at a table in the staff lounge, from the district's approved-vendor list. Many are annuity products with costs and surrender terms the owner has never had explained. None of that makes your account bad — but it makes it worth reading. Bring the statement; we will tell you what you own, what it costs, and what your options are. California runs an official comparison site for exactly this — 403bcompare.com, administered by CalSTRS — and our full guide is at 403(b) plans for California educators.
Social Security: the rules changed in 2025
Most CalSTRS members do not pay Social Security taxes on their CalSTRS-covered teaching wages, so those years do not earn Social Security credit. But many educators have Social Security from somewhere else — summer and private-sector jobs, a career before teaching, or a spouse's record.
For decades, two federal rules — the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO) — reduced the Social Security benefits of many public-pension recipients. That law has changed: the Social Security Fairness Act, signed in January 2025, repealed both, and public pension recipients now receive their own, spousal and survivor Social Security benefits unreduced.
Be careful with sources: most articles and handouts written before 2025 still describe WEP and GPO as current law. They are out of date — verify your own figures with the Social Security Administration at ssa.gov.
For teachers the repeal matters more than for almost anyone: WEP and GPO fell hardest on educators, and a generation of staff-lounge wisdom ("your pension wipes out your Social Security") is now simply wrong. If you wrote off a spousal or survivor benefit before 2025, re-check it.

Where we are actually useful
We do not administer pensions and cannot change your benefit. What we add is the modelling the system will not do for you: how the pension interacts with everything else you own, so the irreversible elections get made with the full picture in view.
- Survivor elections. Choosing an option reduces your monthly benefit permanently in exchange for continuing payments to a beneficiary. Whether that trade is right depends on your spouse's own benefits, your other assets, and life insurance you may already hold.
- Service credit purchases. Sometimes excellent value, sometimes not. It depends on your age factor, how long you will collect, and what else the money could do.
- The 403(b) alongside it. Many California educators hold high-cost annuity-based 403(b) products sold in staff rooms. Reviewing what you actually own, and its real cost, is often the single highest-value hour we spend with a teacher.
- Social Security coordination. With WEP and GPO repealed in 2025, benefits many educators wrote off are back on the table.
Common questions
Should I take the lump sum instead of the monthly benefit?
CalSTRS does not generally offer a lump-sum alternative to the lifetime benefit in the way some private pensions do. The choices that do exist — such as the Defined Benefit Supplement, which is a separate account with its own distribution options — have different rules, so start by confirming with CalSTRS exactly what you have been offered before comparing anything.
Is buying service credit worth it?
Sometimes. It raises your benefit permanently, so the answer turns on cost, your age factor, and how long you expect to collect. It is arithmetic, and we are glad to run it with you.
I have a 403(b) I do not understand.
You are in the majority. Bring the statement. We will tell you what it costs, what it does, and whether it belongs in your plan — with no obligation attached. Start with our 403(b) guide and the state's official comparison site, 403bcompare.com.
Will my CalSTRS pension reduce my Social Security?
No — not anymore. WEP and GPO were repealed by the Social Security Fairness Act signed in January 2025; benefits you or your spouse earned are paid unreduced. Teaching wages still do not generally pay into Social Security, so teaching years still earn no new credit — the repeal restores what was earned elsewhere.
