How TCRS calculates your benefit
The rules here come from the TCRS member guides published by the Tennessee Treasury: the Legacy guides for teachers and for state and higher education employees, and the Hybrid guide for state employees and teachers. Local government plans and public safety supplements differ and aren't covered.
Legacy: 1.5% x AFC x Years, then x 1.05 (max 94.5% of AFC)
Hybrid: 1.0% x AFC x Years (max 90% of AFC)
AFC is the average of your highest 5 consecutive years. In the Legacy plan the 5% statutory improvement makes the effective rate 1.575%, which is where that number comes from. The guide's example: 0.015 x $50,000 x 30 = $22,500 a year, $1,875 a month, then $1,968.75 after the 5% increase. The Hybrid guide's example: 1% x $30,000 x 30 = $9,000 a year, or $750 a month. At a $50,000 AFC, 30 years pays $15,000 a year in the Hybrid plan against $23,625 in Legacy.
Legacy eligibility
Once vested (5 years), a Legacy member can take an unreduced service retirement at 60, or at any age with 30 years. The Legacy plan has no Rule of 80 or Rule of 90.
Early retirement opens at 55, or before 55 with 25 years. The benefit drops 0.4% for every month before you would have qualified for service retirement, so leaving at 55 with 25 years costs 24%. With fewer than 10 years, the early benefit is also capped: 25% of it at 5 years, 40% at 6, 55% at 7, 70% at 8 and 85% at 9. Under 55, a second actuarial reduction to the age-55 amount applies, and TCRS doesn't publish that factor.
The Hybrid Plan
State employees, higher education employees and teachers hired on or after July 1, 2014 are in the Hybrid Plan. The employer puts 4% of pay into TCRS and 5% into your State 401(k). You put 5% into TCRS and are auto-enrolled at 2% in the 401(k), which you can change.
The pension is unreduced at 65 with 5 years or with the Rule of 90. Early retirement is open at 60 with 5 years or with the Rule of 80, with an actuarial reduction. The guide's example is a 60-year-old with 25 years whose benefit is multiplied by 0.612933, a cut of about 39%. Other factors aren't published, so the calculator shows the unreduced amount and points you to a TCRS estimate.
Vesting and leaving early
Both plans vest after five years of creditable service. Leave before that and you can take a refund of your contributions plus interest, which ends your TCRS membership. Leave after vesting and you can keep the account and draw a pension once you meet the age rules.
COLA
After a full year of benefits, TCRS raises payments each July by the CPI change, capped at 3%. A CPI rise of 0.5% to 0.99% gets 1%; under 0.5% gets nothing. Increases compound. Hybrid COLAs can be reduced or suspended if the plan's cost controls are triggered.

Frequently asked questions
How is a Tennessee TCRS Legacy pension calculated?
1.5% of your average final compensation (AFC, your highest 5 consecutive years) x years of service, then increased 5% by statute. TCRS's example: $50,000 AFC and 30 years is $22,500 a year, $1,875 a month, and $1,968.75 after the 5% improvement. That works out to an effective 1.575% a year. Higher earners add 0.25% per year on AFC above the Social Security integration level, which TCRS sets as the 35-year average of the Social Security wage base, rounded to the nearest $600: $98,400 for 2025 and $102,000 for 2026 by that rule. The calculator applies it for your retirement year.
When can Legacy members retire?
Unreduced at 60, or at any age with 30 years of service, once vested (5 years). There's no Rule of 80 or Rule of 90 in the Legacy plan. Early retirement starts at 55, or earlier with 25 years, and costs 0.4% for each month before you'd qualify for service retirement. Retiring at 55 with 25 years cuts the benefit 24%.
How does the Hybrid Plan work?
State employees, higher education employees and teachers hired on or after July 1, 2014 are in the Hybrid Plan. The pension pays 1.0% of AFC per year of service, capped at 90% of AFC, and the employer also puts 5% of pay into your State 401(k). Unreduced retirement comes at 65 with 5 years or with the Rule of 90 (age + service = 90).
Can Hybrid members retire early?
Yes, at 60 with 5 years or with the Rule of 80, but the pension is actuarially reduced. TCRS's guide gives one example: a 60-year-old with 25 years receives 61.29% of the full benefit, a cut of about 39%. The guide doesn't publish the full table, so get your factor from a TCRS estimate.
Does Tennessee TCRS have a COLA?
Yes. After 12 months of benefits, retirees get a raise each July: none if CPI rose less than 0.5%, 1% if it rose 0.5% to 0.99%, and the full CPI increase up to 3% otherwise, compounded. Hybrid COLAs can be cut or suspended under the plan's cost controls.
