Kentucky TRS Retirement Calculator: How to Use It
Your TRS account type decides almost everything. A member who entered before July 2008 earns 2.5% a year from year one. A member who entered after earns as little as 1.7% until service builds up.
What this calculator does
It estimates the Option I annuity (life annuity with refundable balance) for a nonuniversity TRS member, using the multipliers in KRS 161.620 and the retirement rules in KRS 161.600. It projects your service to your planned retirement age, decides whether that's an unreduced, reduced or deferred retirement, and shows the 1.5% COLA over time.
It doesn't model university members, survivor options, disability retirement or the TRS 4 supplemental account. For your official number, request an estimate through Pathway or from TRS at 800-618-1687.
What each input means
TRS account type
TRS 1: entered before July 1, 2002. TRS 2: July 1, 2002 to June 30, 2008. TRS 3: July 1, 2008 to Dec. 31, 2021. TRS 4: on or after Jan. 1, 2022. Your Pathway account shows which one you're in.
Current age and years of service so far
The calculator adds the years between today and your planned retirement age to your current service. Include purchased service and service credit for unused sick leave you expect at retirement. Sick leave credit raises the benefit but doesn't count toward the 27-year or age-and-service tests, so check that you meet them without it.
Years of service before July 1, 1983 (TRS 1 only)
Those years earn 2% instead of 2.5%. Leave it at 0 if you started after mid-1983.
Final average salary
The average of your 5 highest salaries, or the 3 highest if you're in TRS 1-3 and retire at 55 or older with 27 years. Late-career raises above what your district generally gave are limited.
Planned retirement age
The age you leave and start the annuity. If you'd leave before you're eligible but with at least 5 years, the calculator shows the deferred annuity that starts unreduced at 60 (or 60 or 65 for TRS 4).
Understanding the outputs
TRS 1 with 28 years and a $62,000 FAS: 2.5% x 28 x $62,000 = $43,400 a year. TRS 3 with the same numbers is also at 2.5%, because 28 years is above 26. At 18 years the two split: TRS 1 gets 2.5% x 18 x $62,000 = $27,900 and TRS 3 gets 2% x 18 x $62,000 = $22,320.
Early cuts are permanent. A TRS 3 member leaving at 57 with 15 years is 3 years under 60 and 12 years short of 27, so the smaller number, 3, applies: 3 x 6% = 18%. A TRS 1 member at 57 with 25 years loses 2 x 5% = 10%, since 2 years short of 27 is smaller than 3 years under 60.
The COLA table compounds 1.5% a year. The first July 1 increase is prorated if you've been retired less than 12 months, so year one is often a little lower than shown.

Frequently asked questions
What is the difference between TRS 1, TRS 2, TRS 3 and TRS 4?
Entry date. TRS 1 entered before July 1, 2002 and earns 2.5% a year. TRS 2 entered July 1, 2002 to June 30, 2008 and earns 2.5% once it has 10 years (2% below that). TRS 3 entered July 1, 2008 to Dec. 31, 2021 and earns 1.7% to 2.5% depending on total service. TRS 1-3 add 3% for each year above 30. TRS 4 entered on or after Jan. 1, 2022 and earns an age factor plus a career factor, 1.7% to 2.4%, plus a separate supplemental account.
How does the 27-year rule work?
TRS 1, 2 and 3 members can retire unreduced at any age once they have 27 years of Kentucky service. Service credit for unused sick leave raises the benefit but can't be used to reach 27. TRS 4 has no 27-year rule; its earliest unreduced date is 57 with 30 years.
How is the final average salary calculated?
The average of your 5 highest annual salaries. TRS 1-3 members retiring at 55 or older with 27 years use the 3 highest. Raises in the final 3 years (5 for TRS 4) count only up to the increase generally given to your employer's TRS-covered staff, under 102 KAR 1:340.
Does Kentucky TRS provide a COLA?
Yes, 1.5% every July 1 under KRS 161.620(2). It compounds and is prorated in your first year. For TRS 4 the board can adjust it on the foundational benefit if funding falls short.
Does Kentucky TRS coordinate with Social Security?
School district and state agency members don't pay Social Security on TRS-covered pay, so there's nothing to coordinate. Since the WEP and GPO repeal in January 2025, Social Security you earned in other jobs isn't reduced because of the TRS annuity.
