A person receiving Social Security benefits at the age of 66 usually receives the full amount to which he is entitled, as opposed to those who apply for benefits earlier than 66. The exact dollar amount each person receives varies from individual to individual.
Social Security benefits are determined by the number of years a person works and the amount of money he earned during that time. Typically, a person must have been earning an income for 35 years or more to be eligible for benefits. If he is eligible for benefits, they depend on the average annual income for the 35 years he was working.
