Find your group
From your plan and two dates: the date you joined TRSL (before or after July 1, 1999) and the date you first joined any Louisiana state system (the 2011 and 2015 lines). Without the second date we use the first.
Member Handbook p. 13 ('Eligibility requirements are based upon the plan you are in and when you first became a member of one of Louisiana's four state public retirement systems'); p. 8; R.S. 11:761(A)(3)-(4); R.S. 11:701(5)(a); Member Handbook p. 13, Regular Plan: Retirement eligibility (Membership prior to July 1, 1999); R.S. 11:761(A)(1); R.S. 11:768(A); Member Handbook p. 13, Membership between July 1, 1999 - December 31, 2010; R.S. 11:761(A)(2); R.S. 11:768(B); Member Handbook p. 13, Membership between January 1, 2011 - June 30, 2015; R.S. 11:761(A)(3); Member Handbook p. 13, Membership on or after July 1, 2015; R.S. 11:761(A)(4); Member Handbook p. 14, Plan B: Membership prior to July 1, 2015; R.S. 11:802(A); Member Handbook p. 14, Plan B: Membership on or after July 1, 2015; R.S. 11:802(B) - 2
Project your service
We add the time from today to your retirement date to the service you enter, one month of credit per month. Unused leave you enter counts in the formula only.
Member Handbook pp. 7-8, What is service credit?; How do I earn service credit?; R.S. 11:761(A)(2)(b) - 3
Check the retirement rules
Your age and service on the retirement date against your group's full-benefit rules, then its earlier rules (the 2.0% factor, or 20 years at any age).
Member Handbook p. 13, Membership prior to July 1, 1999 (2.5% benefit factor); R.S. 11:768(A)(2); Member Handbook p. 13, Membership prior to July 1, 1999 (2.0% benefit factor); p. 14, NOTE ('Early retirement for those who joined TRSL prior to July 1, 1999, is calculated with a lower 2.0% benefit factor'); R.S. 11:761(A)(1); R.S. 11:768(A)(1); Member Handbook p. 13, Membership between July 1, 1999 - December 31, 2010; R.S. 11:761(A)(2)(a); R.S. 11:768(B)(1); Member Handbook p. 13; R.S. 11:761(A)(3)(a); R.S. 11:768(B)(1); Member Handbook p. 13; R.S. 11:761(A)(4)(a); R.S. 11:768(B)(1); Member Handbook p. 14; p. 23; R.S. 11:802(A); R.S. 11:803(A); Member Handbook p. 14; R.S. 11:802(B)(1); R.S. 11:803(A) - 4
Apply the formula
Years × your FAC × the factor, plus $300 a year for members who joined before July 1, 1986, limited to 100% of FAC. That's the Maximum Option.
Member Handbook p. 7, What will my monthly retirement benefit be?; p. 9, What is a benefit factor?; R.S. 11:768; R.S. 11:768(C); R.S. 11:803(B); DROP Handbook p. 4 ('Some members may work long enough to earn 100% of their average salary (typically 40 years of service for Regular Plan members)'); R.S. 11:768(A)(1), (A)(2) - 5
Early retirement with 20 years
TRSL doesn't publish its actuarial cut. We show the benefit before the cut as an "up to" amount and how many years early you'd be. If TRSL gives you your cut, enter it.
Member Handbook p. 14, What does actuarially reduced mean?; R.S. 11:768(B)(2); R.S. 11:761(A)(3)(b), (A)(4)(b) - 6
DROP and options
Your DROP window from the DROP Handbook's rules (36 months plus a 60-day grace period to apply). Payment options other than the Maximum are labelled without amounts.
DROP Handbook pp. 3-8; R.S. 11:786; R.S. 11:787; Member Handbook pp. 11-12, Choosing a retirement option; Death & Survivor Benefits p. 13; R.S. 11:783(A)
What the calculator doesn't cover
- Your final average compensation. We use the number you enter; TRSL figures it from your records with the 10% or 15% salary cap.
- The actuarial cut for retiring with 20 years at any age (joined on or after July 1, 1999), and the factors for Options 1-4A and the ACO. TRSL doesn't publish them.
- Future raises (PBIs), DROP interest, the ILSB's effect on your own check, and the supplemental benefit after DROP or return to work.
- Disability retirement, School Lunch Plan A, the Optional Retirement Plan and Louisiana's other state systems.
- Health premiums, federal taxes and the cost of buying service.
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 every worked example in TRSL's handbooks and brochures, and against the edges of each rule (birthdays, the 1999, 2011 and 2015 dividing dates, the DROP window). The tests run every time the site is built.

TRSL's ACO brochure prints $1,939.00 for year 1; 2.5% on $1,892 is $1,939.30, which matches the brochure's own cumulative total. See "Where sources disagreed" below.
Things to check with TRSL
The sources don't settle these points. Each is labelled "Check with TRSL" where it shows up on the site.
If you joined on or after July 1, 1999 and retire at any age with 20 years, TRSL cuts your benefit by an actuarial factor. It doesn't publish the factors, so we can't show the cut.
We show your full benefit before the cut as an "up to" amount, with how many years early you'd be. If TRSL gives you your reduction, enter it and we'll apply it.
Member Handbook p. 14TRSL doesn't publish how much Options 1 to 4A (or the Annual COLA Option) lower your check. They depend on your age and your beneficiary's age.
We show the Maximum Option amount only. The other options are labelled and have no dollar figure.
Member Handbook pp. 11-12; ACO brochure p. 2State law adds $300 a year for members who joined before July 1, 1986. TRSL's handbook doesn't mention it.
We add $300 a year for those members and say so on the result.
R.S. 11:768(A)(1)-(2)If you joined before July 1, 1999 and retire with 20 years before 60, the handbook shows the lower 2.0% factor and no extra actuarial cut.
We use 2.0% with no other reduction.
Member Handbook pp. 13-14; R.S. 11:761(A)(1); R.S. 11:768(A)(1)Your real service can grow by less than a year a year (part-time work, leave without pay, the one-year-per-fiscal-year limit).
We add one month of service for each month from today to your retirement date.
Member Handbook p. 8, How do I earn service credit?Raises after retirement (permanent benefit increases) need the Legislature's approval and enough money. Their size and timing aren't known.
We don't add any future raise to your estimate. Examples of a 2% raise are labelled as examples.
Guide for Retirees pp. 6-7; R.S. 11:883.5TRSL doesn't set or publish retiree health premiums. Your former employer or the Office of Group Benefits does.
We don't show any premium amounts.
Planning for Retirement p. 14; R.S. 11:827State law words the salary cap for years 4 and 5 of a five-year average a little differently from TRSL's handbook.
We apply your group's cap (10% or 15%) to every year when we explain it. The calculator uses the average you enter.
R.S. 11:701(5)(a); Member Handbook p. 9State law also lets members who joined before 2011 enter DROP at 65 with 20 years. TRSL's DROP Handbook leaves that out.
We follow the DROP Handbook and don't use the age 65 rule.
R.S. 11:786(A)(1); DROP Handbook p. 7Where sources disagreed
- DROP eligibility: age 65 with 20 years (members before 2011). TRSL DROP Handbook (Apr. 2026), p. 7 lists only 30 years any age, 55/25 (2.5%) and 60/10 (2.0%). R.S. 11:786(A)(1) also allows 20 years at age 65 (2.5%). What we do: Engine follows the handbook (the 65/20 criterion is kept in drop.statuteOnlyCriterion, unused). A member with 20 years at 65 will almost always have reached 60/10 first, which starts the DROP window anyway.
- Return-to-work rules. TRSL Guide for Retirees (Apr. 2026), pp. 9-10 describes the 2010, 2020 and 2022 RTW laws (25% of benefit / 25% of FAC limits, etc.). TRSL Returning to Work (Aug. 2026), p. 1: Act 344 of 2026 replaces all other RTW laws (50% of FAC limit, age 65 provision). legis.la.gov shows R.S. 11:710-710.2 repealed by Acts 2026, No. 344, eff. July 1, 2026. What we do: Use the August 2026 RTW booklet (newer, matches the statute repeal). The April 2026 Guide for Retirees is out of date on this point.
- ACO example, year 1 amount. TRSL ACO brochure (Oct. 2024), p. 2 shows $1,939.00 for the 1st year. The same brochure's 2.5% rule and its own cumulative table ($45,975.60 after year 1 = $22,704 + 12 x $1,939.30) give $1,892 x 1.025 = $1,939.30. What we do: Tests use the 2.5% formula ($1,939.30) and note the $0.30 discrepancy; years 5-23 match the formula exactly.
- Member Handbook page cross-references. TRSL Member Handbook (Apr. 2026), p. 22 says Regular Plan eligibility is on 'page 14' and p. 23 says Plan B eligibility is on 'page 13'. The tables are actually on p. 13 (Regular Plan) and p. 14 (Plan B). What we do: Cites use the actual pages.
- $300 annual addition for members before July 1, 1986. Not mentioned in the Member Handbook (formula on p. 7 is service x FAC x factor only). R.S. 11:768(A)(1)-(2) adds $300 a year for persons who became members before July 1, 1986. What we do: Handbook is silent rather than contrary; the engine adds $300/yr for those members and says so in a note. Flagged in needsValidation.
- Sick leave periods. TRSL Member Handbook (Apr. 2026), p. 19 lists three periods (on/before June 30, 1988; July 1, 1988-June 30, 1990; on/after July 1, 1990). TRSL Sick Leave (Oct. 2026), PDF pp. 2-5 uses two tables (on/before June 30, 1988; on/after July 1, 1988), with the 1-year cap for leave earned on/after July 1, 1990. What we do: Consistent in substance; the helper uses the brochure's two tables and leaves the 1-year cap to the caller.
