While the APRS benefit software cannot produce calculations using future salary amounts, you can calculate your potential benefits using your own future estimated salary average and your estimated years of service. This approach can provide you with an approximate estimate of your full life annuity.
The calculation is: Final Monthly Average Salary (36 mos. for Group A; 60 mos. for Group B) X Years of Creditable Service X Multiplier (3.2% for Group A; 2.5% for Group B).
Example: $8,000 X 23 years X 3.2% = $5,888 gross monthly life annuity benefit
