What is Texas TRS?
The Teacher Retirement System of Texas (TRS) is a statewide defined benefit pension plan for eligible public education employees in Texas.
It provides a lifetime monthly annuity calculated under a statutory formula based on years of service and final average salary, rather than individual investment account balances.
Membership is generally automatic for qualifying public education employment, with contributions from employees, employers, and the state funding the system alongside investment returns.
Retirement eligibility and benefit amounts vary by
- Membership tier and
- Service history
..making the plan primarily a function of tenure and earnings.

How our TRS Retirement Calculator works
Estimate how much you’ll receive in retirement by starting with your
- Current age
- Service credit, and
- Salary.
From there, we project how your benefits grow up to your planned retirement age using expected salary increases and additional years of service.
We then calculate your estimated pension using a defined benefit formula based on your service credit, final average salary (FAS), and a fixed benefit multiplier.
Finally, we adjust your estimate based on your retirement choices, including survivor benefits, early retirement reductions, and partial lump sum options.
When calculating your retirement benefit, our default assumptions include:
- A 2.3% benefit multiplier per year of service credit applied to your final average salary
- A 3-year or 5-year final average salary period, depending on your selected tier
- Salary increases of 2%–8% annually, based on your expected raise input
- Service credit growth until retirement, based on your planned retirement age
- Vesting requirement of 5 years of service credit (minimum eligibility rule)
- Eligibility rules such as the Rule of 80, the 30-year rule, and age-based retirement at 65
- Early retirement reductions for retiring before full eligibility
- Survivor benefit options (single life, 50%, or 100%) that adjust monthly payments
- Partial lump sum option (PLSO), which trades monthly income for upfront cash
- Inflation / COLA assumptions to model long-term purchasing power
- A retirement planning horizon up to age 120 for lifetime income projections
But, of course, you can change any of these default numbers by adjusting your inputs in the calculator.
