We count the years beginning with 1951, or (if later) the year you reach age 22, and ending with the earliest of the year before you reach age 62, become disabled, or die. Years wholly or partially within a period of disability (as defined in
§ 404.1501(b) of
subpart P of this part) are not counted unless your primary insurance amount would be higher. In that case, we count all the years during the period of disability, even though you had no earnings in some of those years. These are your elapsed years. From your elapsed years, we then subtract up to 5 years, the exact number depending on the kind of benefits to which you are entitled. You cannot, under this procedure, have fewer than 2 benefit computation years.
