How the TRS Texas formula works
Texas uses one of the simplest defined benefit formulas in the country. There is no age factor table and no graded multiplier. Every year of service credit is worth the same thing:
Final average salary means the average of your five highest annual salaries. They do not have to be consecutive, which quietly helps anyone who took a lower-paying assignment late in their career. If you are one of the small number of grandfathered members in Tiers 1, 4 or 6, the average is taken over your three highest years instead — a meaningful difference if your pay rose sharply at the end.
Worked example
- Years of service credit
- 28
- Five-year final average salary
- $68,000
- Multiplier (28 × 2.3%)
- 64.4%
- Age at retirement
- 62
- Rule of 80 check (62 + 28)
- 90 ✓
- Annual annuity
- $43,792
When you can actually collect it
This is where Texas gets complicated. TRS has six tiers, and the tier you fall into depends on when you joined and whether you met grandfathering criteria back in 2005. Anyone hired today lands in Tier 5. The practical rules for that tier:
| Path | Requirement | Reduction |
|---|---|---|
| Normal retirement | Age 65 with 5+ years | None |
| Rule of 80 | Age 62 or older AND age + service ≥ 80 | None |
| Rule of 80 before 62 | Age + service ≥ 80, under age 62 | 5% per year under 62 |
| 30 years of service | 30+ years, under age 62 | 5% per year under 62 |
| Early retirement | Age 55 with 5+ years | Up to 53% |
The Rule of 80 is not a free pass on its own
A lot of Texas teachers believe hitting the Rule of 80 means an unreduced pension at any age. For Tier 5 members it does not. You need the Rule of 80 and age 62. Meet the Rule of 80 at 57 and you will still take a 25% permanent cut — five years under 62 at 5% a year. That is the single most expensive misunderstanding in this plan.
The gap between the two reduction schedules
Notice that the last row of the table is far harsher than the two above it. If you reach the Rule of 80 or 30 years of service, your penalty is capped at a predictable 5% per year. If you do not, you fall onto the full actuarial reduction, which TRS says can reach 53% at age 55. The difference between retiring with 29 years and 30 years of service can therefore be tens of thousands of dollars a year, permanently.
Why our estimate for that path is approximate
TRS publishes the maximum reduction but not the full table — the actual factors live in TRS Rules 29.11 and 29.12. Where this calculator has to use that path, it interpolates and labels the result as an approximation. Request an official estimate from TRS before making a decision on it.
There is no cost-of-living adjustment
This is the part of the Texas plan that surprises retirees most. The TRS handbook is direct about it: the plan does not provide for regular cost-of-living increases, and any post-retirement increase must be authorized by the Legislature. Your annuity is, by default, a fixed dollar amount for life.
The Legislature does act occasionally. The most recent increase came through Senate Bill 10 in 2023, after Texas voters approved Proposition 9 in November of that year. It paid 2%, 4% or 6% depending on when the member retired, and showed up in January 2024 annuity payments. Before that, retirees had gone years without one.
Plan accordingly. At 3% inflation, a fixed $43,000 annuity has the buying power of about $32,000 after ten years and $24,000 after twenty. Members who rely on TRS alone and do not save separately feel this sharply in their seventies.
Texas teachers and Social Security
Roughly 96% of TRS public school members do not pay into Social Security for their teaching employment, so most Texas educators earn no Social Security credit for those years.
WEP and GPO are gone
If you earned Social Security from another job, or qualify for a spousal or survivor benefit, those payments used to be cut by the Windfall Elimination Provision and the Government Pension Offset. The Social Security Fairness Act repealed both, and they have not applied to any month since January 2024. Most affected people were adjusted during 2025 and received a lump sum.
If you never applied for Social Security because WEP or GPO would have wiped out your benefit, apply now. Retroactivity is generally capped at six months, so waiting costs you money that you cannot get back later.
What you and your employer pay in
| Who | Rate |
|---|---|
| Member (retirement) | 8.25% of salary |
| Member (TRS-Care retiree health) | 0.65% |
| State of Texas | 8.25% |
| Public education employer | 2.00% |
The 89th Legislature in 2025 left the multiplier, tiers, contribution rates and COLA policy untouched. House Bill 2 raised teacher pay and confirmed those raises count as creditable compensation, which lifts future accruals but does nothing for people already retired. Texas legislates every two years, so the next opportunity for change is the session beginning in January 2027.
Four things people get wrong
- Assuming the Rule of 80 means no reduction. For Tier 5 you also need to be 62. See above — this one is expensive.
- Using their final salary instead of the five-year average. If your pay climbed at the end of your career, the average is meaningfully lower than your last paycheck, and so is your pension.
- Budgeting as though a COLA will arrive. Sometimes one does. You cannot plan on it.
- Not claiming Social Security they are now owed. Anyone who skipped applying during the WEP and GPO era should apply immediately.
Frequently asked questions
What is the Rule of 80 in TRS Texas?+
The Rule of 80 is met when your age plus your years of service credit total 80 or more. For Tier 5 members — everyone hired today — meeting it is not enough on its own: you must also be at least 62 to retire without a reduction. If you meet the Rule of 80 before 62, your annuity is reduced 5% for each year you are under 62.
Does TRS Texas pay a cost-of-living adjustment?+
No, not automatically. The TRS plan does not provide for regular cost-of-living increases. Any increase must be authorized by the Texas Legislature. The most recent was Senate Bill 10 in 2023, which paid 2% to 6% depending on retirement date and appeared in January 2024 annuity payments.
How many years do I need to be vested in TRS Texas?+
Five years of service credit. Vesting entitles you to a future annuity; it does not by itself let you start collecting, which depends on the age and service rules for your tier.
Do Texas teachers get Social Security?+
About 96% of TRS public school members do not participate in Social Security for their teaching employment, so they earn no credit for those years. Social Security earned from other work is now paid in full: the Windfall Elimination Provision and Government Pension Offset were repealed effective January 2024.
Is my TRS pension capped?+
The formula itself has no explicit cap, but IRS section 415(b) limits what any qualified defined benefit plan may pay — $290,000 for 2026. In practice almost no Texas educator approaches that ceiling.
