At 30 years there's no early cut, only the 1%-a-year reduction (30% at 30 years).
T-DROP participants get the 3% COLA each July 1 as if retired; deposits rise by 3% of the initial T-DROP deposit each year. T-DROP pamphlet p. 2, Do Members Receive a COLA in T-DROP?; 24 CAR § 10-704(b)(1); Actuarial valuation 2025 p. C-3, item 7

Interest
Interest accrues at 3% compounded annually; the Board may authorize an incentive rate (up to 6% total). A member who retires out of T-DROP before July 1 gets no T-DROP interest for that last fiscal year. Member Handbook p. 17; T-DROP pamphlet p. 2, How much Interest does T-DROP Earn?; 2026 Retirement Planner p. 10 (Regular T-DROP Interest rate 3%); 24 CAR § 10-706(a), (c)
Regular T-DROP interest = fixed 3% + incentive up to 3% (Resolution 2017-35); the incentive may be granted if ATRS's estimated return is 2% above the assumed return. FY 2025: 3% + 0%. Actuarial valuation 2025 pp. C-3 to C-4, item 7
Interest is credited each June 30 'on the mean balance'. Our calculator's illustration credits rate x (opening balance + half the year's deposits). The exact mean-balance method and any incentive rate for 2026-2027 aren't published in our sources.
What would settle it: ATRS T-DROP statement or the Board resolution setting 2026-2027 T-DROP interest.After 10 years
After 10 years, deposits stop but interest continues, credited each June 30, at 4% to 6% (variable rate = ATRS return - 2%, floor 4%, cap 6%; with incentive up to 7.5%). 2026-2027: 4%. Member Handbook p. 19, What if I do not leave T-DROP after 10 consecutive years?; T-DROP pamphlet p. 2; 2026 Retirement Planner p. 10 (Post 10-Year T-DROP Interest rate 4%); 24 CAR § 10-706(b); Actuarial valuation 2025 p. C-4 (Resolution 2017-36)
Working enough days
To earn a quarter's deposit you must work a minimum number of days in it:
| Quarter | Minimum days |
|---|---|
| July - September | 15 |
| October - December | 25 |
| January - March | 25 |
| April - June | 15 |
Member Handbook p. 18, quarter table; 24 CAR § 10-705(c)(2)
When you leave T-DROP
At retirement the T-DROP balance can go to any mix of the 4 options totaling 100%. The election can be changed until the end of the second full calendar month after the effective retirement date, except a rollover. Member Handbook p. 19, What happens to my T-DROP deposit account after I retire?; T-DROP pamphlet p. 1; 24 CAR § 10-710
- Annuitize into the monthly benefit
- Lump sum
- Transfer to the ATRS Cash Balance Account (CBA)
- Rollover to a qualified plan (irrevocable)
Once you retire out of T-DROP you cannot participate again. Member Handbook p. 19
The Cash Balance Account
If you move your balance to ATRS's Cash Balance Account (CBA), it earns a rate that steps up each fiscal year. For CBAs established on or after July 1, 2021, credited monthly:
| Year in the CBA | Rate |
|---|---|
| Year 1 | 2.5% |
| Year 2 | 2.75% |
| Year 3 | 3% |
| Year 4 | 3.25% |
| Year 5 | 3.5% |
| Year 6 and after | 4% |
The handbook's table and ATRS's rules go from 3.5% to 4% in year 6; the planner's "0.25% each year" wording doesn't match, so we follow the table. Member Handbook p. 45, Appendix C; p. 20, Cash Balance Account; 24 CAR § 10-712(a)(3), (b), (g)
Your health insurance and school benefits don't change while you're in T-DROP. Member Handbook p. 49; T-DROP pamphlet p. 2 ('No loss of school benefits')
From the sources
- T-DROP lets you keep working instead of retiring. Your benefit is frozen and a monthly deposit goes into a T-DROP account that earns interest. You need 30 years of service for full participation, or 28 for early entry. You enter only on July 1 (apply March 1 - May 31).Member Handbook pp. 17-18; T-DROP pamphlet p. 2
- The deposit is your would-be benefit reduced by 1% for each year of service (30 years = 30% less). Entering at 28 or 29 years cuts it a further 12% or 6%.Member Handbook p. 17; 2026 Retirement Planner p. 4
- The actuary's example: 28 years and a $35,000 average give a $21,070 benefit. The T-DROP deposit is $13,350 a year, rising by about $400 a year with the COLA.Actuarial valuation 2025 p. C-12
- T-DROP interest is 3% compounded annually, credited June 30 on the mean balance. The Board may add an incentive (up to 6% total). If you retire before July 1, you get no interest for that last year.Member Handbook p. 17; T-DROP pamphlet p. 2
- Deposits run for up to 10 years. If you keep working after that, deposits stop but the balance earns post-10-year interest of 4% to 6% (4% for 2026-2027).Member Handbook p. 19; 2026 Retirement Planner p. 10
- When you retire, the T-DROP balance can be added to your monthly benefit, paid as a lump sum, rolled over, or moved to ATRS's Cash Balance Account. The CBA earns 2.5% the first year, rising to 4% from the sixth year.Member Handbook pp. 19-20, 45
