Project your service
We add the time from today to your retirement date to the creditable and membership service you enter, one year per year, and add unused sick leave at one month per 20 days.

Check eligibility
Your age (in full months) and service on the retirement date, against the unreduced rules (65 with 5 years of membership service, 60 with 25, or 30 at any age) and the early rules (50 with 20, or 60 with 5).

Work out the formula benefit
1.82% of the average you enter, rounded to the cent as on the handbook's worksheet, times your years of creditable service.
Handbook: Benefit Calculations, TSERS Retirement Formula; Benefit Calculation Worksheet, p. 1 - 4
Apply any early reduction
Age 60-65 with fewer than 25 years: 0.25% for each month before the 1st of the month on or after your 65th birthday. Age 50-59: the better of the age-based and service-based cuts in state law, which match the handbook's table.

The yearly amount, paid monthly, under Option 1 (maximum allowance).
Handbook: Benefit Calculations, TSERS Retirement Formula
The rules behind each step are explained in plain English on the benefit formula, early retirement and payment options pages. Try them on your own dates in the calculator.
What the calculator doesn't cover
- Your average final compensation. We use the number you enter.
- Payment option amounts (Options 2, 3, 4, 6-2, 6-3). TSERS doesn't publish its factors.
- The contribution-based benefit cap and the IRS 415(b) limit.
- The pre-July-1994 actuarial alternative for ages 50-59.
- Law enforcement officer rules, disability retirement, and the cost of buying service.
- Taxes, health premiums and other deductions from your check, and any future increases.
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 the handbook's worked examples, every cell of both early-retirement tables, and the "Examples of Benefits Paid" chart (47 of 50 cells match; the other three are handbook errors listed below). The tests run every time the site is built.
| Example | Source shows | Our engine | Source |

Things to check with the Retirement System
The sources don't settle these points. Each is labeled "Check with the Retirement System" where it shows up on the site.
The handbook's early-retirement table shows 52% at age 53 with 20 years. The state law's formula gives 50%, and every other cell in the table follows the formula.
We use the handbook's 52% at exactly 53 with 20 years, and the formula everywhere else.
G.S. 135-5(b21)(2)c.; Handbook: Benefit Calculations, Between the ages of 50 and 59 with fewer than 30 years of creditable serviceIf your service began before July 1, 1994 and you retire between 50 and 59, the law also lets TSERS pay the actuarial equivalent of your age-60 benefit if that is larger. The factors for this aren't published.
We don't calculate this. Your benefit could be a little higher than our estimate.
G.S. 135-5(b21)(2)c.3.Between birthdays, the reduction changes month by month. The law counts months to the 1st of the month on or after your 60th or 65th birthday. The handbook only says it is 'adjusted proportionately'.
We count months the way the law describes.
G.S. 135-5(b21)(2)b.-c.; Handbook: Benefit Calculations, Early Retirement PercentagesThe handbook doesn't say exactly how TSERS rounds. Its worksheet rounds 1.82% of your average to the cent before multiplying by service; its example chart drops the cents.
We follow the worksheet. Expect differences of a few cents to a dollar.
Benefit Calculation Worksheet, p. 1; Handbook: Benefit Calculations, Examples of Benefits PaidThree amounts in the handbook's 'Examples of Benefits Paid' chart don't match its own formula: $90,000 at 55 with 28 years and at 60 with 25 years, and $35,000 at 60 with 25 years ($1,337 printed; the formula gives about $1,327).
We use the formula.
Handbook: Benefit Calculations, Examples of Benefits PaidIn the handbook's payment option example, Option 6-3 pays John $1,909.20 and his spouse $954.10. Half of $1,909.20 is $954.60.
We show half of the member's amount, as the option is described.
Handbook: Example of Payment OptionsTSERS doesn't publish the factors used to figure Options 2, 3, 4, 6-2 and 6-3. They depend on your age and your beneficiary's age.
We describe the options in words and show the handbook's one example. Get your amounts from an ORBIT estimate.
Handbook: Example of Payment Options; G.S. 135-5(g)Option 4's higher payment before 62 is figured actuarially. The handbook example can't be reproduced without TSERS's factors.
We show only that the payment drops by your Social Security estimate at 62, as in the example.
Handbook: Example of Payment OptionsThe handbook says your average uses your four highest-paid years (48 months) in a row. The law says four consecutive calendar years.
We use the average you enter. Our worksheet helper uses four yearly salaries in a row.
Handbook: Benefit Calculations; G.S. 135-1(5)The handbook lists 'noncontributory' and 'partially contributory' retiree health with the same eligibility, and says the cost depends on the plan you pick. It doesn't say which plan is which, or give premiums.
We show these two together as one tier.
Handbook: Health Coverage in RetirementThe return-to-work earnings floor is published only for 2026 ($43,300). It goes up each January with inflation.
We show the 2026 figure.
Return to Work Laws page (myncretirement.gov)Retirees with an average of $100,000 or more (adjusted each year) may be affected by the contribution-based benefit cap. The current threshold and the cap formula's factor aren't published in the handbook.
We don't apply the cap; we flag it when your average is $100,000 or more.
Handbook: Benefit LimitationsThe state law lists retiree supplements through 2023, and the Retirement Systems reported the 2026 supplement. We haven't checked the 2024 and 2025 session laws.
We list only the increases we found in the sources.
G.S. 135-5(uuu)-(zzz); Retirement Monitor, July 2026One handbook section says you vest with five years of membership service; another says five years of creditable service.
We use membership service (the time you paid into TSERS).
Handbook: Qualifying for BenefitsTo find your earliest and full-benefit dates, we assume you keep working full time and earn one year of service per year.
This is a planning assumption, not a TSERS rule.
Handbook: Benefit Calculations, TSERS Retirement FormulaSick leave converts at one month per 20 days, plus one month for any leftover of at least one hour. A 'day' follows your employer's policy.
We assume an 8-hour day unless you tell us otherwise.
Handbook: Adding to your Creditable Service, Sick leaveWhere sources disagreed
- Age 53 with 20 years. The handbook table shows 52%; the statute's formula gives 50%. We follow the handbook at that one point. Check with the Retirement System
- Average final compensation. Handbook says '48 consecutive months'; statute says 'four consecutive calendar years'. Following the handbook wording; for a calendar-year salary history both give the same result.
- Employer rate. Handbook Administration and Funding page (modified 02/13/2025) still shows 16.79% employer rate for FY ending June 30, 2025. We use the July 2026 Retirement Monitor's 26.1%.
