Updated September 3, 2026. Quick answer: Teachers’ and State Employees’ Retirement System of North Carolina (TSERS): the COLA is discretionary (the General Assembly must act), service credit can be purchased, and no DROP was found. Vesting takes five years of membership service.
Provisional. This page is published at medium confidence. The specific points that could not be confirmed are listed under What could not be verified below, and are named rather than smoothed over.
The verdicts
| Is the COLA granted? | Discretionary (General Assembly) |
|---|---|
| Is the COLA compounded? | Not stated |
| Vesting | 5 years of membership service |
| Buy service credit? | Yes |
| DROP? | None found |
| State | North Carolina |
Those first two rows are separate questions and are routinely confused. Whether you get an increase at all is one thing; whether it compounds is another. A system can grant an increase automatically every year and still compute it against your original benefit forever, which is a materially worse deal than it sounds.
The COLA
TSERS increases are not automatic: “It is up to the General Assembly to decide whether to increase benefits for TSERS and whether to appropriate funds to support that goal.” No increase or supplement was granted in 2024 or 2025 per the state retirement system’s own COLA page. Whether the adjustment compounds on the prior balance or resets against an original base is not stated in the materials reviewed.
Buying service credit
TSERS lets members purchase a long list of service types: military, withdrawn service, out-of-state and federal government service, temporary local/state service, educational leave, omitted service, charter school service, workers’ compensation leave, part-time service, extended illness leave and more. No single flat-rate formula for military-service cost was found in the materials reviewed; instead, “State law specifies how the cost of each type of creditable service that may be purchased is calculated.” Cost varies by category and is spelled out on the individual purchase form for each type: “Each purchase form includes a description of the cost calculation method used for that individual type of purchase.”
Run your own numbers before deciding: some purchases never recover their cost, and the calculator shows which.

- No fee to request a match
- No obligation to hire
Expect questions about your situation, your name, email and phone, and phone verification by text. A match is not guaranteed.
The form is run by Kapitalwise, our advisor-matching partner. Kapitalwise sends your details to advisers who pay for the introduction, so expect calls and texts. Clear Money Guide is paid when you submit the form, whether or not you ever hire anyone. This is free to you and there is no obligation to hire anyone.

How our partner relationships workVesting
“You become vested in TSERS once you have completed a minimum of five years of membership service.” A vested member who leaves before retirement age can defer: “You may be entitled to receive a deferred benefit at a later date once you meet eligibility requirements after you have completed five years of creditable service, provided you do not withdraw your contributions.”
DROP
No DROP program appears in the TSERS handbook pages reviewed. Only a standard vested deferred benefit was found, which defers commencement of an already-earned benefit rather than letting a member accrue a separate account while still working: a different mechanism than a DROP.
DROP is rarer than it appears across the systems on this site: most have none.
TSERS payment options and the survivor election
The TSERS handbook has an Example of Payment Options page that puts real numbers on the survivor choice. It follows one hypothetical member: “Assume John Murphy has earned a service retirement benefit under the maximum allowance of $2,000 a month.” He retires at 57 after 30 years and three months of creditable service and wants to share the benefit with his spouse, Pam, who is 51. The page then lists what John and Pam would receive under each option, and the table below reproduces those figures next to some simple arithmetic.
Two cautions come with it. The page says “These are only examples.” It adds that “Each member’s benefit is calculated individually”, and that actual amounts “are based on many factors, such as your age, your beneficiary’s age and when payments start”. Pam is six years younger than John in the example, so the gaps below belong to that age pairing.
| Payment option | To John | To spouse after John’s death | Computed monthly give-up versus $2,000 | Computed share of $2,000 |
|---|---|---|---|---|
| Option 1: Maximum Allowance | $2,000 monthly | $0.00 | none | 100% of the maximum |
| Option 2: 100% Joint & Survivor | $1,843.60 monthly | $1,843.60 monthly | a computed $156.40 | a computed 92.18% |
| Option 3: 50% Joint & Survivor | $1,918.60 monthly | $959.30 monthly | a computed $81.40 | a computed 95.93% |
| Option 6-2: Modified Joint & Survivor | $1,824.60 monthly | $1,824.60 monthly | a computed $175.40 | a computed 91.23% |
| Option 6-3: Modified Joint & Survivor | $1,909.20 monthly | $954.10 monthly | a computed $90.80 | a computed 95.46% |
The arithmetic is simple subtraction and division on the page’s own numbers, and TSERS does not state these results. Under Option 2 the computed give-up is $156.40 a month ($2,000 minus $1,843.60), a computed 92.18% of the maximum, and Pam would receive the same $1,843.60 monthly afterward. Under Option 3 the computed give-up is $81.40 ($2,000 minus $1,918.60), a computed 95.93% of the maximum, with $959.30 monthly going to the spouse, which matches half of John’s $1,918.60 (computed: $959.30). How a choice like this compares with a single-life benefit is covered in single life versus joint and survivor pension.
The two Modified Joint & Survivor rows add a feature the page describes in one line each: “If the spouse dies before John, he receives $2,000 monthly thereafter.” Their computed give-ups are $175.40 (Option 6-2, a computed 91.23% of the maximum) and $90.80 (Option 6-3, a computed 95.46%). Option 6-3 shows $954.10 to the spouse, while half of John’s $1,909.20 is a computed $954.60, so the page’s spouse figure for that row is a computed $0.50 below a straight half. The page does not explain that difference, so any such row is worth confirming against an official estimate.
Option 4, Social Security Leveling, works differently. The page shows “$2,670.00 monthly up to age 62, $1,670.00 monthly thereafter.” The step-down is a computed $1,000 a month, which equals the example’s assumption that John’s primary Social Security benefit is $1,000 per month at age 62. After the step-down John’s benefit sits a computed $330 below the $2,000 maximum, and the spouse column shows $0.00.
Eligibility timing matters for any of these elections. The handbook states: “Generally, if you die before your effective retirement date, your beneficiary is ineligible for a monthly retirement allowance”, and it names an exception, the Survivor’s Alternate Benefit, which the pages read do not describe further. It also requires that, to be legally retired, a member must “live until your effective date of retirement”.
What the pages read do not state: the factors behind each option, any Option 5, whether and when an option can be changed after retirement, or what happens to a joint option if the spouse dies first (apart from the two Modified rows). The member’s own estimate from TSERS is where real figures come from.

What could not be verified
REFUND TERMS: this page does not state what happens to your contributions if you take a refund instead of leaving your account with the system: that comparison was not independently researched for this system this session, and is left as an open gap rather than guessed from another system’s rule. Consult your own plan’s refund/forfeiture terms before deciding. Any additional field marked “not stated” in the verdicts table above was genuinely absent from the official materials read, not omitted for space.
