Your Social Security Statement provides you with a list of your Social Security earnings each year through your previous year's wages. It will tell you the current estimate (in today's dollars) of your retirement benefit at the age you requested, as well as the benefit at full retirement age and at age 70. It also tells you the projected amount of disability benefits and survivor benefits your family may receive.
Review your record of earnings carefully. If they do not agree with your own records, contact the Social Security Administration at 1-800-772-1213. You will need past W-2 forms, pay stubs, tax returns, or any other proof of your earnings.
