To use this table*

  1. Find your monthly rate of earnings in the first column. (For estimating purposes, divide your highest one year's salary by 12.)
  2. Find your years of service credit (top line).
  3. Your approximate monthly pension at age 50 or older will be the amount shown at the point where your earnings line and the service column intersect.

For example:

25 years of service credit and final rate of earnings of $1,500 a month will provide a SLEP pension of $900 per month at age 50 or older.

*Due to space limitations, we are unable to show all possible monthly "Final Rate of Earnings." If your rate is not shown above and you wish to obtain an estimate of your future SLEP pension, you may request an estimate by calling IMRF Member Services at 1-800-ASK-IMRF (1-800-275-4673).
