Example: If you were born in 1952 and you wanted to calculate your AIME for the year 1978, and your income for that year was $21,112.06. Than you would divide $44,321.67, the National Average Wage in 2012 when you turn 60, by $10,556.03, the National Average Wage in 1978. 44,321.67/10,556.03 = 4.1987 Which you would then multiply by $21,112.06. 4.1987 x 21,112.06 = $88,643.34 in 2012 dollars
