Find your plan
You pick it, or we use your hire date: before July 1, 2014 is Legacy, on or after is Hybrid. If you lost Legacy membership and came back after June 30, 2014, pick Hybrid.

Project your service
We add the time from today to your retirement date to the service you enter, one month of credit per month. The work-longer comparison adds a year of service for each year.
Our assumption (see below) - 3
Check the retirement rules
Your age and service (in whole months) on the retirement date, against your plan's full-benefit rules, then its early rules.

Apply the formula
Legacy: 1.5% of your average up to the Social Security integration level plus 1.75% above it, × years, limited to 90% of your average, then +5%. Hybrid: 1% × average × years, limited to 90%.

Apply the early cut
Legacy: 0.4% a month, up to 60 months, and the extra limit under 10 years. Under 55, and for Hybrid early retirement, TCRS doesn't publish the factor, so we show an "up to" amount: the most your check could be.

Add the dates
Earliest and full-benefit dates, the first COLA date, and which payment options your beneficiary allows.

In short: the calculator finds your plan, applies the formula (1.5% Legacy, 1% Hybrid), checks full and early eligibility, and shows an "up to" amount where TCRS doesn't publish a factor. Try the Legacy guide's example.
What the calculator doesn't cover
- Your average final compensation. We use the number you enter; TCRS figures it from your records.
- The Hybrid early-retirement factor (except TCRS's one example) and the Legacy factor under 55. TCRS doesn't publish them.
- Survivor option and Social Security Leveling amounts. TCRS doesn't publish the factors.
- The Hybrid Plan's 401(k). Its balance depends on contributions and investments.
- The Legacy minimum benefit, the after-65 comparison for members who joined before July 1, 2011, and the Hybrid dollar cap.
- Disability retirement, the cost of buying service, taxes, health premiums and the actual COLA each year.
- State and higher-education employees, local government plans and the Optional Retirement Plan.
How we check the math
The calculator runs on a small engine that reads every rule from one data file, with a source for each. Automated tests check it against every worked example in the TCRS member guides and flyers, plus the edges of each rule (birthdays, the July 1, 2014 plan date, the 60-month limit on the Legacy cut, the 10-year limit, the COLA bands). The tests run every time the site is built.
| Example | Source shows | Our engine | Source |
|---|---|---|---|
| Legacy, age 60, 30 years (a month) | $1,968.75 | $1,968.75 | Legacy Member Guide p. 5, Service Retirement example Match |
| Legacy, age 55, 25 years, 24% cut (a month) | $1,246.88 | $1,246.88 | Legacy Member Guide p. 6, Early Retirement example (24% reduction) Match |
| Legacy, age 55, 7 years, 55% limit (a month) | $192.02 | $192.02 | Legacy Member Guide p. 6, under-10-years example (55% cap) Match |
| Legacy, $100,000 average above the SSIL (a month) | $3,967.69 | $3,967.69 | Legacy Member Guide p. 7, Social Security Integration Calculation example Match |
| Legacy flyer, $30,000 average, 30 years (a year) | $14,175 | $14,175 | Legacy flyer p. 1, Benefit Calculation Example Match |
| Hybrid, age 60, 30 years (a month) | $750.00 | $750.00 | Hybrid Member Guide p. 6, Service Retirement Formula example Match |
| Hybrid early, age 60, 25 years (a year) | $4,597 | $4,597 | Hybrid Member Guide p. 7, early retirement example Match |
| Adjusted age difference, 60 and 34 | 16 | 16 | Legacy Member Guide p. 10, Joint and Survivor Plans Match |
| Out-of-state years billed, 29 + 4 | 1 | 1 | Purchasing Out-of-State Service p. 3 Match |
The Hybrid guide rounds its early example to $383 a month; our engine's $383.08 is the same $4,597 a year divided by 12.
Things to check with TCRS
The sources don't settle these points. Each is labeled "Check with TCRS" where it shows up on the site.
TCRS cuts a Legacy early benefit 0.4% for each month before you'd qualify for a full benefit. The guides don't say whether the 30-year date assumes you keep working.
We count months to age 60 or to the date you'd reach 30 years if you kept working, whichever is sooner, and never more than 60 months.
Legacy Member Guide p. 6; Legacy actuarial valuation 2025 p. G-4If you retire from the Legacy Plan before 55 with 25 or more years, TCRS adds a second, actuarial cut to bring the benefit to its value at 55. TCRS doesn't publish that factor.
We show the benefit after the 0.4%-a-month cut as an "up to" amount. Your real check will be lower.
Legacy Member Guide p. 7The extra limit for early retirement with fewer than 10 years is listed only for whole years (5 to 10).
We use your completed whole years: 7.5 years counts as 7.
Legacy Member Guide p. 6The Social Security integration level changes every year. The sources give only 2025 ($98,400) and 2026 ($102,000).
For other years we use the nearest published year and say so.
Legacy actuarial valuation 2025 p. G-1The Legacy maximum is 94.5% of average pay. The guide doesn't say whether the extra 0.25% above the integration level counts toward it.
We apply the maximum to the whole formula. It matters only with about 60 years of service.
Legacy Member Guide p. 4TCRS cuts a Hybrid early benefit by an actuarial factor that depends on how far you are from full retirement. It publishes only one example: 0.612933 at age 60 with 25 years.
We show your unreduced Hybrid benefit as an "up to" amount. Your real check will be lower. For age 60 with exactly 25 years we use the published factor.
Hybrid Member Guide p. 6-7The Hybrid maximum is the lower of 90% of average pay or $80,000 indexed each year since July 1, 2014. The current indexed dollar amount isn't published.
We apply only the 90% limit. It affects very few people.
Hybrid actuarial valuation 2025 p. 29TCRS doesn't publish how much each survivor option or the Social Security Leveling option reduces your check.
We show the Member Only amount and describe the other options without dollar figures. Your TCRS benefit estimate shows them.
Legacy Member Guide p. 5, p. 9-11Two 70% survivor options (Options 5 and 6) appear in TCRS's beneficiary guide and application slides but not in the member guides.
We list them, marked as not in the member guides.
Selecting a Beneficiary Guide p. 13; Retirement application guide p. 12The return-to-work chart lists a salary limit for 120-day temporary employment ("60% of salary plus 5% added annually") but its layout doesn't make clear what it applies to.
We quote the chart and don't calculate a limit.
Return to Work Requirements p. 5Who qualifies for teacher retiree health coverage, and how much the state pays toward it, is in a Benefits Administration guide we couldn't download.
We show only what the 2027 premium sheet and TCRS's checklist say: premiums are tiered by years of service.
Retirement Checklist p. 3; 2027 teacher retiree premiums p. 1TCRS's actuarial report lists a minimum Legacy benefit per year of service. The member guide doesn't mention it or say how it works with early retirement.
We don't apply a minimum. It would matter only for very small benefits.
Legacy actuarial valuation 2025 p. G-3, G-5Legacy members who joined before July 1, 2011 and work past 65 get the larger of their regular benefit or an adjusted age-65 benefit. That needs TCRS's actuarial factors.
We show the regular benefit and a note. Ask TCRS for the comparison.
Legacy Member Guide p. 7Where sources disagreed
- The Legacy and Hybrid member guides (12/2024, 07/2024) list four joint-and-survivor options. The Selecting a Beneficiary Guide and the Preparing to Submit a Retirement Application slides list six (adding 70% Options 5 and 6, non-spouse limit 23 years).

- Member guides compute the adjusted age difference with 70; the Beneficiary Guide uses the IRS RMD age (70 1/2/72/73/75). Engine follows the member guide by default and can use the RMD age. Legacy Member Guide p. 10; Selecting a Beneficiary Guide p. 11
- Legacy guide: the pre-62 increase is 'a portion' of the age-62 Social Security amount but the reduction at 62 is 'the full amount'. Application slides and Beneficiary Guide: increase and reduction are 'designed to be equal to the full amount'. Valuation: total income approximately the same before and after. Legacy Member Guide p. 10; Retirement application guide p. 10; Selecting a Beneficiary Guide p. 11; Legacy actuarial valuation 2025 p. G-2
- The application slides say Option 5 'reduces the member's maximum retirement benefit by 70%'; the Beneficiary Guide says the beneficiary receives 70% of the member's benefit. Read as a 70% survivor option. Retirement application guide p. 12; Selecting a Beneficiary Guide p. 13
- Legacy guide: pre-July 1997 accidental disability 52.5% of AFC, then 34.96% at 62. Valuation: 50%# then 33-1/3%# (# = 105%, i.e. 52.5% and 35.0%). Legacy Member Guide p. 9; Legacy actuarial valuation 2025 p. G-6
- Hybrid flyer says teachers 'hired after July 1, 2014' in the body but 'hired on or after July 1, 2014' in the title; the Hybrid guide says 'hired after June 30, 2014'. Engine uses on/after July 1, 2014. Hybrid flyer p. 1; Hybrid Member Guide p. 2
- Legacy guide: non-vested membership lost after 'more than seven consecutive years' away; Hybrid guide: 'seven years or more'. Legacy Member Guide p. 3; Hybrid Member Guide p. 4
- Hybrid flyer: '90 day window to opt out of the 401(k) plan and obtain a refund'; Hybrid guide: 30 days to opt out before a contribution is made, 90 days to request a refund of default contributions. Hybrid flyer p. 2, footnote 4; Hybrid Member Guide p. 3-4, p. 12
- Hybrid guide lists five cost-control steps; the valuation lists six, starting with using the stabilization reserve and ending with freezing accruals. Hybrid Member Guide p. 16; Hybrid actuarial valuation 2025 p. 4
- Hybrid valuation: $80,000 indexed annually from July 1, 2014; the political-subdivision outline in the Legacy valuation says indexed annually after 2012 (that outline also covers the separate Alternative Plan). Hybrid actuarial valuation 2025 p. 29; Legacy actuarial valuation 2025 p. H-55
