The Wisconsin Retirement System was created to protect public employees and their beneficiaries against the financial hardships of old age and disability , to attract and retain a qualified public workforce, establish modest benefits and achieve administrative savings.

How the WRS Pension Works

The Wisconsin Retirement System is a qualified retirement system under Section 401(a) of the Internal Revenue Code. It is a hybrid defined benefit plan , containing elements of both a 401(k) or defined contribution plan and a defined benefit plan.

The intention of the WRS pension plan is to provide you with a lifetime retirement payment (annuity ) once you are vested and have reached minimum retirement age . Your retirement annuity is calculated using both a formula calculation and a money purchase calculation and as a retiree , you receive the higher of the two benefit calculations.

The Retirement Calculations

Your money purchase benefit is calculated by multiplying your money purchase account balance by a factor based on your age. This money purchase balance is shown on your annual Statement of Benefits .

Your formula benefit is based on your three highest years of earnings ("final average earnings "), a formula multiplier (based on your employment category ), your years of creditable service (including any creditable military service) and an actuarial reduction if you retire before your normal retirement age .

Participating members will receive a Statement of Benefits every year. It shows your account balances, earnings, years of service, and much more. Keep this document with your important papers. See the Statement of Benefits page for more information.

In most cases a retirement benefit is paid as a monthly annuity payable for your lifetime.

Who is Eligible to Participate in the WRS?

The Wisconsin Retirement System covers state and local public employees, including faculty and staff of the University of Wisconsin System, local police and firefighters, and all publicly-employed teachers in the state.  

Your employer is required to cover you as a participating employee if your job position meets WRS Participation Requirements:

If you first became a WRS employee on or after July 1, 2011:
  • You must be expected to work at least 2/3 of full-time.
    • 880 hours for teachers and educational support employees of school districts and
    • 1,200 hours for all other non-teaching employees.
  • You are expected to be employed for at least one year.
If you first became a WRS employee before July 1, 2011:
  • You must be expected to work at least 1/3 of full-time.
    • 440 hours for teachers and educational support employees of school districts and
    • 600 hours for all other non-teaching employees.
  • You are expected to be employed for at least one year.

If your position is not expected to meet both requirements when you are first hired, you will not be enrolled in the WRS. If your position meets the eligibility criteria at a later date, you may become eligible and be enrolled in the WRS at that time.

If you left employment under the WRS and closed your account by taking a lump sum benefit, you must meet the participation requirement upon returning to WRS employment again.

Part-Time Workers

Working part-time will affect your WRS benefits, including retirement, health insurance, disability, and more.

For more information see the How Part-Time Employment Affects Your WRS Benefits (ET-2121) brochure.

Contributions to Your WRS Account

The money to pay WRS benefits come from employee- and employer-required contributions and investment (interest) earnings.  The largest amount comes from investment earnings. All the monies are managed by The State of Wisconsin Investment Board (SWIB). The amount that you and your employer pay are (by law) based on a percentage of your annual salary. You can see this percentage and how it changes over the years on our WRS Contribution Rates page. Employers pay 50% of the total amount required and employees pay the other 50%.

This money is put into the Core Trust Fund . You may also choose to put 1/2 of the contributions into the higher-risk investment fund called the Variable Trust Fund . Each fund is credited with a separate effective rate of interest each December. The effective rates are based on how the funds perform each year. Go to the Core and Variable Funds page to learn more.


Vested members are eligible to receive a retirement benefit at age 55 (age 50 for protective category members) once they terminate all WRS employment. Members who are not vested may only receive a separation benefit.

You may have to meet 1 of 2 vesting laws depending on when you first began WRS employment:

  • If you first began WRS employment after 1989 and terminated employment before April 24, 1998, then you must have some WRS creditable service in 5 calendar years.
  • If you first began WRS employment on or after July 1, 2011, then you must have 5 years of WRS creditable service.
    • 1 year of creditable service is based on the hours you work. To earn 1 year of service, teachers need to work 1,320 hours and all other employees need to work 1,904 hours.

If neither of the vesting laws above apply to you, then you were vested when you first began WRS employment.

If You are Vested and Have Reached Minimum Retirement Age:

When you stop working a WRS job, you may apply for a retirement benefit. The minimum retirement age is 55 for most employees and age 50 for protective category employees. See the When Can I Retire page for more information.
