The Teacher Retirement System of Texas formula — 2.3% × years of service × final average salary — with the Rule of 80 eligibility check most calculators skip.
Estimate your TRS Texas pension
Standard formula for members not grandfathered under pre-2007 rules.
Assumes standard, non-grandfathered rules. Members who met certain criteria on or before Aug. 31, 2005 may be grandfathered under different, preserved provisions — confirm your specific tier and grandfathered status through MyTRS. If Rule of 80 isn't met, an early-age reduction applies that isn't precisely modeled here.
The TRS Texas formula
TRS Texas calculates your standard (unreduced) annual annuity as: 2.3% × years of service credit × final average salary. Final average salary is generally the average of your highest 5 years of salary for most members (some members are grandfathered under different rules based on their membership date).
The Rule of 80 — the eligibility test worth checking first
A worked example, straight from TRS's own materials
TRS Texas's own published example: a member with a final average salary of $50,000, age 58, and 22 years of service credit. Age (58) plus service (22) equals exactly 80 — Rule of 80 is met, so the annuity is unreduced. The calculation: 2.3% × $50,000 × 22 years = $25,300 per year, or $2,108.33 per month.
Why "TRS" isn't just one system
| State | Formula basis (approximate) |
|---|---|
| Texas | 2.3% × years × final avg salary (highest 5 yrs), Rule of 80 |
| Georgia | 2% × years × highest 2 consecutive years' avg salary |
| Kentucky | Different multiplier and eligibility (27 yrs KY service, or 60 with 5 yrs) |
| New York | Tier-based (III/IV/VI), different final average salary period |
If you're an educator outside Texas, search for your specific state's TRS (or equivalent) calculator instead — the formulas genuinely aren't interchangeable, even though the "TRS" name is shared.
Texas TRS formula and Rule of 80 mechanics verified directly against trs.texas.gov's own published FAQ and worked example, matched exactly to the dollar. This is a planning estimate — TRS itself audits reported salaries when preparing an official estimate, which can produce a different figure than a self-service calculation. Request an official estimate through MyTRS or Form TRS 18 for a precise number.
Frequently asked questions
Before you plan around your TRS pension.
What is the TRS Texas benefit formula?
2.3% multiplied by your years of service credit, multiplied by your final average salary (generally your highest 5 years), gives your standard annual annuity if you meet the Rule of 80 or are age 65+.
What is the Rule of 80?
If your age plus your years of service credit equals 80 or more, your annuity is paid at the full, unreduced formula amount. Falling short of this before age 65 triggers an early-age reduction.
What if I'm not a Texas educator — does this apply to my TRS?
No — Georgia, Illinois, Kentucky, New York, and other states also use "TRS" as a system name, each with a genuinely different formula. This calculator is specifically built for Teacher Retirement System of Texas.
What does "grandfathered" mean for TRS Texas members?
Members who met certain criteria on or before August 31, 2005 may retain older, preserved benefit provisions that were otherwise repealed in a 2005 plan change. This calculator assumes standard, non-grandfathered rules — check your specific status through MyTRS.
Is this calculator's estimate official?
No. TRS audits your actual reported salaries when preparing an official estimate, which can differ from a self-service calculation. Request an official estimate through your MyTRS account or Form TRS 18 for a precise figure.
