If David retires at the age of 70, the last year he worked he earned $40,000. His replacement rate is: 50%.
We would be using this formula to determine the replacement rate
Replacement rate=Social security payments/Amount earned last year ×100
Where:
Social security payments=$20,000
Amount earned last year=$40,000
Let plug in the formula
Replacement rate=$20,000/$40,000
Replacement rate=0.5×100
Replacement rate=50%
Therefore If David retires at the age of 70, the last year he worked he earned $40,000. His replacement rate is: 50%.
