Mandatory Retirement Plans
Mines does not participate in the Social Security program. In lieu of Social Security, most non-student employees must enroll in the Colorado Public Employees Retirement Association (PERA). PERA has two types of plans- a DB Plan and a DC Plan. The employee contribution is set to 11% as of 2024. Mines’ employer contribution is set at 20.95%.

PERA DB & DC
The PERA DB Plan is a pension plan where your contributions are invested by professionals for you and you receive a lifetime benefit.
In the PERA DC Plan, you direct your investments to an array of fund options, and retire with the account balance you have at that time.
