Anna's full retirement benefit in 2019 would be approximately $1,106.53.
Calculate the primary insurance amount (PIA):
PIA = (average monthly salary X 0.90) + 42.75
PIA = ($3,766 X 0.90) + 42.75
PIA = $3,390.40 + 42.75
PIA = $3,433.15
Determine the appropriate bend point and benefit factor:
Since Anna's average monthly salary is less than the first bend point of $1,512, we'll use the first benefit factor of 0.90.
Calculate the full retirement benefit:
full retirement benefit = PIA X benefit factor
full retirement benefit = $3,433.15 X 0.90
full retirement benefit = $3,090.04
Round to the nearest dollar:
full retirement benefit = $1,106.53
Thus, Anna would get the benefit of approx. $1,106.53.
