When Can You Retire as a Texas Teacher? Tiers and TRS Calculator

You can retire as a Texas teacher with a full, unreduced TRS pension at age 65 with at least five years of service credit, or earlier under the Rule of 80, which lets you retire once your age plus your years of service credit add up to 80, provided you also meet the minimum age set for your tier. Earlier retirement is possible at 55 with five years of service, or at any age with 30 years, but both paths carry a permanent reduction to your monthly check.¹

Start by Finding Your Tier

TRS places every member in one of six tiers, and your tier is what sets the age you need to hit alongside the Rule of 80. Log into the MyTRS portal to see yours. As a rough guide: Tiers 1 through 4 generally cover members who had at least five years of service credit by August 31, 2014 and kept continuous membership. Tiers 5 and 6 cover members who first joined on or after September 1, 2014, had fewer than five years of credit on that date, or withdrew their contributions and later rejoined.²

The tier matters because the same career can produce very different retirement dates depending on when you joined. A member who hits the Rule of 80 at 51 in one tier may have to wait more than a decade longer in another.

Full-Benefit Retirement by Tier

Every tier requires at least five years of service credit before any retirement benefit is payable. From there, the thresholds break down this way:¹

Tiers 1 and 2: age 65 with five years of credit, or the Rule of 80 with no minimum age attached.
Tiers 3 and 4: age 65 with five years of credit, or at least age 60 while meeting the Rule of 80.
Tiers 5 and 6: age 65 with five years of credit, or at least age 62 while meeting the Rule of 80.

Here is what that looks like in practice. A Tier 1 member who started teaching at 22 could retire at 51 with full benefits (22 + 29 years = 51, plus 29 years of service = 80). A Tier 5 member with the exact same career would hit the Rule of 80 at the same point but still have to wait until 62 to retire without a reduction.²

Early Retirement and What It Costs

If you can’t meet the full-benefit requirements for your tier, TRS still allows two early paths. You can retire as early as age 55 with five years of service, or with 30 or more years of service at any age even if you haven’t yet reached the Rule of 80. Both reduce your monthly annuity permanently.³

The reduction math depends on your tier. For a Tier 5 member who meets the Rule of 80 but retires before 62, TRS cuts the annuity by 5% for each year under 62. Retire at 59 and the check shrinks by 15% for life. Tier 6 has a useful exception: members between ages 55 and 61 who meet the Rule of 80 with at least 20 years of service avoid the actuarial reduction, though TRS still classifies them as early-age retirees. Tier 6 members under 55 who meet the Rule of 80 still face the 5%-per-year reduction below age 62.²

These reductions don’t disappear when you reach a later age. They stay on the check for the rest of your life. Leaving one year early can cost tens of thousands of dollars over a long retirement, which is why testing a few different retirement dates before committing is worth the time.

Purchased Service Credit Can Move the Date

If you’re close to a threshold but short on years, you may be able to purchase credit for military duty, out-of-state public school teaching, substitute teaching of at least 90 days in a school year, withdrawn contributions from a prior TRS membership, or developmental leave. Military credit is capped at five years and requires at least five years of Texas public school service first.⁴ Out-of-state teaching credit also requires five years of TRS membership service, with up to one year purchasable for each year of Texas service, to a maximum of 15. Most purchased credit is priced on the actuarial value of the extra benefit, so it costs more the closer you get to retirement.

How Much Each Year of Service Is Worth

Knowing when you can retire is only half the picture. The size of the check tells you whether retiring at the first eligible date actually works for your household. The formula is the same across all six tiers: years of service credit multiplied by 2.3%, multiplied by your average salary.⁵

With 30 years of service, that’s 30 × 2.3% = 69% of your average salary. On a $60,000 average, that’s $41,400 a year, or roughly $3,450 a month before taxes and insurance. Twenty-five years gets you to 57.5%, and 35 years to 80.5%.

Which salary years get averaged depends again on your tier. Tiers 1, 4, and 6 use your three highest annual salaries. Tiers 2, 3, and 5 use the five highest.² A three-year average rewards late-career salary jumps; a five-year average smooths them out.

Check your years and salaries against your annual TRS Statement of Account. If a year is missing, you have five years from the end of that school year to report the discrepancy in writing.⁶

Running Your Own Numbers

The MyTRS portal has a retirement calculator that compares different retirement dates side by side, showing the standard annuity and other payment options for each scenario. You can download the results as PDFs. These are projections, not guarantees. Salary assumptions, service credit purchases, and legislative changes can all shift the final figure.⁷

Within 10 to 12 months of your target retirement date, submit Form TRS 18 or request a formal estimate through MyTRS. TRS processes the request and mails a retirement packet within 60 days, which confirms that your records match theirs and locks in the figures used for your application.⁸

The Health Insurance Gap Before Medicare

If you’re thinking about retiring well before 65, factor in TRS-Care premiums for the years before you reach Medicare. For 2025, the monthly premium under TRS-Care Standard (for participants without Medicare) is $200 for retiree-only coverage, $689 with a spouse, and $999 for family coverage.⁹

Once you turn 65, you must enroll in Medicare Part B to keep TRS-Care coverage. Skipping Part B means losing TRS-Care entirely. If you qualify for premium-free Part A, you have to enroll in that too. Once you move to TRS-Care Medicare, premiums drop sharply: $75 a month for retiree-only and $280 for retiree-plus-spouse, with 2026 premiums holding at the 2025 levels.¹⁰

A member who retires at 56 and reaches Medicare at 65 is looking at nine years of pre-Medicare premiums, which exceeds $21,000 for individual coverage alone. That number belongs in any early retirement calculation, right next to the annuity reduction.

A Note on Social Security

Most Texas school districts don’t participate in Social Security, so for most members the TRS annuity is the main retirement income. If you also worked in jobs that paid into Social Security, the Windfall Elimination Provision and Government Pension Offset used to reduce those benefits for people drawing a non-covered pension. The Social Security Fairness Act, signed on January 5, 2025, eliminated both provisions retroactive to January 2024.¹¹ If you previously skipped filing because WEP would have wiped out your benefit, it’s worth checking with SSA now.
