How to Calculate IRS Retirement Plans
- 1). Calculate your "high-three" average by taking the three highest consecutive salaries you earned and finding their average by adding them together and dividing the total by 3.
- 2). Multiply the amount of years you worked by 1.1 if you are over age 62 and worked for the IRS for more than 20 years.
- 3). Multiply the number of years you worked by 1 if you are under 62 and/or worked less than 20 years.
- 4). Take the figure from Step 2 or 3 (whichever applies to you), turn it into a decimal. If you worked for 10 years and retired at 65, your decimal is 0.10 (1 x 10 / 100). If you worked for 20 years and retired at 65, your decimal is 0.22 (1.1 x 20 / 100).
- 5). Multiply your decimal by your high-three average. So if both the employees above had high-three averages of $100,000, then the first one's pension will be $10,000 a year ($100,000 x 0.1) and the second one's pension will be $22,000 a year ($100,000 x 0.22).
