Investopedia explains 'Average Indexed Monthly Earnings - AIME'


If you recieve Social Security benefits, the number they used to calculate that benefit is from the Primary Insurance Amount (PIA). In order to calculate the PIA, the AIME is split into three parts. Predetermined percentages are applied to each part and they are all summed together to get the PIA.

For example, suppose your AIME is $5,000. The PIA calculation would take 90% from the first $744, then 32% from earnings over $744 but under $4483, and lastly 15% of monthly earnings over $4483. In this example your PIA would be $1943.63.
