How we estimate Wyoming WRS pensions

Every number on the Wyoming pages comes from a Wyoming Retirement System (WRS) publication, a WRS Board rule, or Wyoming law. Here's what the calculator does, and what it leaves out.

  1. 1

    Find your tier

    Tier 1 if you joined before September 1, 2012; Tier 2 if you joined on or after it, or came back on or after it after taking a refund or before you were vested. You can also pick your tier.

    Handbook p. 7, Benefit Tiers; Handbook p. 7, Benefit Tiers; p. 13, Important Tier 2 Rule; W.S. 9-3-402(a)(xxix); W.S. 9-3-415(d), (m)(vii)
  2. 2

    Use your service

    We use the years you enter as your service at retirement. WRS gives a full month for 86 or more hours in a month and less for fewer hours; we don't count hours for you.

    Handbook p. 9, Months of Service; W.S. 9-3-417(b)
  3. 3

    Check the retirement rules

    Vested at 48 months. Unreduced at 60 (Tier 1) or 65 (Tier 2), or when your age plus service reaches 85. Reduced from 50 (Tier 1) or 55 (Tier 2), or with 25 years at any age. We count your age in completed months.

    Handbook p. 11, Retirement Eligibility Ages and Understanding the 'Rule of 85'; Handbook p. 11, Taking a Reduced Retirement Benefit; Handbook p. 9, Months of Service, and p. 10, Vesting Requirements; W.S. 9-3-415(a), 9-3-416
  4. 4

    Apply the formula

    Your highest average salary × your benefit percentage ÷ 12. Tier 1: 2.125% for each of the first 15 years and 2.25% for each year after. Tier 2: 2% a year. No cap.

    Handbook p. 9, Estimating Your Benefit and Public Employee Pension Benefit Table; W.S. 9-3-418(a), (g)
  5. 5

    Cut it if you retire early

    5% for each year you are under 60 (Tier 1) or 65 (Tier 2), counted by the month. No cut if you meet the Rule of 85. Under 50 or 55, we keep counting at the same rate, with no floor, and label it.

    Handbook p. 11, Taking a Reduced Retirement Benefit; WRS Board Rules ch. 14, sec. 2(a)(i) and 3(b)
  6. 6

    Options and the COLA

    Only Option 1 is in dollars; WRS publishes no option factors. The self-funded COLA (1%, 2%, 3%) is shown as a range from the handbook's approximate starting cuts.

    Handbook pp. 17-18, Benefit Options and Benefit Payout Options; Handbook p. 19, Self-Funded Cost-of-Living-Adjustment (COLA) Feature and How the Trade-off Works; p. 20, Timeline & The Break-Even Point

In short: the calculator finds your tier, applies the formula (2.125% then 2.25% a year in Tier 1, 2% in Tier 2), checks the Rule of 85, and takes off the 5%-a-year early cut where it applies. Try the calculator.

What the calculator doesn't cover

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 benefit table and examples in WRS's handbook, and against the edges of each rule (the September 1, 2012 date, the 15-year step, birthdays, the Rule of 85, 25 years, 86 hours). The tests run every time the site is built.

Things to check with WRS

The sources don't settle these points. Each is labelled "Check with WRS" where it shows up on the site. In plain English: what's unclear, and what would settle it.

Check with WRS

How a part month early is counted

The handbook counts the early cut by the month but doesn't say how part of a month counts. We count it as a whole month, which gives the slightly bigger cut.

What would settle it: A WRS estimate for a retirement date that is not on the birthday day of the month, or written confirmation from WRS.
Check with WRS

How your age counts toward the Rule of 85

We add your age in years and months to your service. WRS might count age differently, which could move your Rule of 85 date by up to a month.

What would settle it: A WRS Board rule or a WRS member statement showing the Rule of 85 date for a member whose birthday falls mid-year.
Check with WRS

Very large cuts under age 50 or 55

If you retire under 50 (Tier 1) or 55 (Tier 2) with 25 years, the cut can be very large. We apply 5% a year, but WRS might handle it another way. Ask WRS for an estimate.

What would settle it: A WRS estimate or Board rule for an early retiree under age 50 (Tier 1) or 55 (Tier 2).
Check with WRS

Option amounts aren't published

WRS doesn't publish how much each option reduces your check. Your online account or a WRS counselor can show the amounts.

What would settle it: A WRS option factor table or several WRS estimates with options for known ages.
Check with WRS

The exact self-funded COLA cut and start date

We show a range for the smaller starting check with a self-funded COLA, based on the handbook. WRS will give you the exact amount.

What would settle it: The WRS Board rule on the self-funded COLA option, or WRS estimates with and without the COLA.
Check with WRS

Part-time work after retirement

The rules for going back to work cover full-time jobs. They don't say what happens with part-time work, so check with WRS before you take a part-time job with a WRS employer.

What would settle it: WRS guidance for retirees working fewer than 86 hours a month for a participating employer.
Check with WRS

Retiree health through your school district

WRS doesn't run retiree health insurance. Whether you can keep your health plan after retiring depends on your school district. Ask your district's HR office.

What would settle it: State of Wyoming Employees' Group Insurance retiree rate sheet and list of participating school districts, or the district's own retiree insurance policy.
Check with WRS

The handbook's state tax sentence

Wyoming law exempts WRS benefits from Wyoming taxes. If you live in another state, that state may tax them. Ask a tax professional.

What would settle it: WRS clarification of the handbook sentence.
Check with WRS

Contribution rates after June 2028

Contribution rates can change every two years. The current rates run through June 2028.

What would settle it: The WRS contribution rate sheet for July 1, 2028.
