How California Teachers Can Supplement Their CalSTRS Pension Through Compound Interest
California educators face a unique retirement landscape. Your CalSTRS pension is one of the most generous defined benefit plans in the country — but California's high cost of living, especially in Los Angeles, San Francisco, and San Diego, means even a strong pension may not be enough to maintain your lifestyle in retirement.
The Cost-of-Living Reality: A CalSTRS pension that replaces 60% of your final salary still leaves a significant gap when you're paying Bay Area or LA County rent. Compound interest in a 403(b) is essential for closing that gap.
— Common Questions —
Frequently asked
Is CalSTRS alone enough for retirement in California?
For most California teachers, CalSTRS replaces about 50–65% of final salary. Comfortable retirement typically requires 70–90%, so a 403(b) supplement closes that gap.
Are California teachers covered by Social Security?
Generally NOT covered (WEP/GPO applies). This affects how much you should contribute to a 403(b) — uncovered teachers should generally save more.
Can I contribute to a 403(b) and an IRA?
Yes — they have separate limits ($23,000 for 403(b) and $7,000 for IRA in 2026, with catch-up amounts at 50+). Many teachers use both.
What happens to my 403(b) if I move out of state?
Your 403(b) is portable and yours regardless of where you live. You can roll it into an IRA when you separate from your district.
How does California's 9.3% state tax affect my withdrawals?
Traditional 403(b) withdrawals are taxed as ordinary income in California. Some states offer partial exemptions for retirement income — check current California rules.
