CalSTRS Pension Calculator

Q: How is a CalSTRS pension benefit calculated?

CalSTRS uses the formula Monthly Benefit = Service Credit Years × Age Factor × Final Compensation ÷ 12. The age factor depends on your membership tier and retirement age — for example, a 2% at 60 member retiring at 60 with 25 service years and $80,000 final compensation gets an annual benefit of 25 × 2.0% × $80,000 = $40,000. Estimate your own benefit with our free CalSTRS Retirement Calculator.

Q: What is the difference between the CalSTRS 2% at 60 and 2% at 62 tiers?

Members hired before January 1, 2013 fall under the "2% at 60" formula, which reaches its maximum 2.4% age factor at age 63. Members hired on or after that date fall under the "2% at 62" formula (part of California's PEPRA reforms), which requires working to age 65 to reach the maximum age factor, and uses a different final compensation averaging period.

Q: What counts as "final compensation" for a CalSTRS pension?

Final compensation is generally your highest average annual earnable salary over a specific period — 12 consecutive months for most 2% at 60 members with 25+ years of service, or a 36-month average for many 2% at 62 members, though specific rules depend on your contract and district.

Q: Can unused sick leave increase my CalSTRS pension?

Yes, in many cases unused sick leave balances can be converted into additional service credit at retirement, which can slightly increase your final benefit calculation. Confirm the conversion rate and eligibility rules with your school district's HR office before retiring.

CalSTRS Defined Benefit Pension: 2% at 60 vs. 2% at 62 Calculations

The California State Teachers' Retirement System (CalSTRS) provides a lifetime defined-benefit pension to California public educators, calculated using service credits, age factors, and final compensation averages.

The CalSTRS Defined Benefit Formula

Annual Pension = Service Credit (Years) × Age Factor (%) × Final Compensation Average

*Monthly Pension = Annual Pension ÷ 12.

CalSTRS 2% at 60 (Hired < 2013)

Normal retirement age is 60 (2.0% age factor). Retiring at 63 yields the maximum 2.4% age factor. Members with 30+ service years receive an additional 0.2% career factor bonus (capped at 2.4%).

CalSTRS 2% at 62 (PEPRA Tier)

For teachers hired on or after January 1, 2013 under PEPRA. Normal retirement age is 62 (2.0% age factor), reaching the maximum 2.4% factor at age 65. Final compensation is calculated over 36 consecutive months.
