Its sole purpose is to help you estimate the net amount of your MPERS benefit payment using different tax withholding options and premium deductions.

This is your link to personalized benefit information.

myMPERS Secure Member Access is a secure portal that allows you to view your individual benefit information, as well as the ability to run retirement benefit estimates and register for seminars.

Personal Benefit Statement

Every spring, MPERS collaborates with various benefit providers to produce your personal benefit Statement.  This statement breaks down the benefits you currently receive as an active state employee, as well as provides you with estimates of your future benefits.  After retirement, a similar benefit statement is provided annually, in the month you receive your COLA, providing detailed information about your benefits, beneficiaries, and deductions.

This link is a sample only!  You can view your benefit statements, with your specific information on myMPERS Secure Member Access. Please review the information contained in your personalize annual benefit statement. If you see incorrect information or have questions regarding that benefit, please contact the appropriate benefit provider as soon as possible.

Record of Important Documents

The Record of Important Documents is intended to provide one place to list all of your important documentation, such as insurance policies, birth or marriage certificates, sources of income (including the providers contact information) and where each of these documents are stored, should the need arise for you, or your loved ones, to locate them.

Retirement Benefit Estimate

This link is a sample only!  Login to myMPERS Secure Member Access to run personalized benefit estimates 24/7. For active employees, the estimates assume you will continue working in the same position, at the same rate of pay, until the date of termination shown on the estimate. All information contained in your benefit estimate must be verified by MPERS before a benefit can be paid.
