(1) Earnings. In computing your average indexed monthly earnings, we use wages, compensation, self-employment income, and deemed military wage credits (see §§ 404.1340 through 404.1343) that are creditable to you for social security purposes for years after 1950.

(2) Computation base years. We use your earnings in your computation base years in finding your average indexed monthly earnings. All years after 1950 up to (but not including) the year you become entitled to old-age or disability insurance benefits, and through the year you die if you had not been entitled to old-age or disability benefits, are computation base years for you. The year you become entitled to benefits and following years may be used as computation base years in a recomputation if their use would result in a higher primary insurance amount. (See §§ 404.280 through 404.287.) However, years after the year you die may not be used as computation base years even if you have earnings credited to you in those years. Computation base years do not include years wholly within a period of disability unless your primary insurance amount would be higher by using the disability years. In such situations, we count all the years during the period of disability, even if you had no earnings in some of them.

(1) For the years 1951 through 1977, four times the amount of average taxable wages that were reported to the Social Security Administration for the first calendar quarter of each year for social security tax purposes. For years prior to 1973, these average wages were determined from a sampling of these reports.

(2) For the years 1978 through 1990, all remuneration reported as wages on Form W-2 to the Internal Revenue Service for all employees for income tax purposes, divided by the number of wage earners. We adjusted those averages to make them comparable to the averages for 1951-1977. For years after 1977, the term includes remuneration for services not covered by social security and remuneration for covered employment in excess of that which is subject to FICA contributions.

(3) For years after 1990, all remuneration reported as wages on Form W-2 to the Internal Revenue Service for all employees for income tax purposes, including remuneration described in paragraph (c)(2) of this section, plus contributions to certain deferred compensation plans described in section 209(k) of the Social Security Act (also reported on Form W-2), divided by the number of wage earners. If both distributions from and contributions to any such deferred compensation plan are reported on Form W-2, we will include only the contributions in the calculation of the average of the total wages. We will adjust those averages to make them comparable to the averages for 1951-1990.

(1) The first step in indexing your social security earnings is to find the relationship (under paragraph (d)(2) of this section) between -

(2) To find the relationship, we divide the average wages for your indexing year, in turn, by the average wages for each year beginning with 1951 and ending with your indexing year. We use the quotients found in these divisions to index your earnings as described in paragraph (d)(3) of this section.

(3) The second step in indexing your social security earnings is to multiply the actual year-by-year dollar amounts of your earnings (up to the maximum amounts creditable, as explained in §§ 404.1047 and 404.1096 of this part) by the quotients found in paragraph (d)(2) of this section for each of those years. We round the results to the nearer penny. (The quotient for your indexing year is 1.0; this means that your earnings in that year are used in their actual dollar amount; any earnings after your indexing year that may be used in computing your average indexed monthly earnings are also used in their actual dollar amount.)

(4) We calculate your indexing year under this paragraph if you, the insured worker, die before reaching age 62, your surviving spouse or surviving divorced spouse is first eligible after 1984, and the indexing year calculated under this paragraph results in a higher widow(er)'s benefit than results from the indexing year calculated under the general rule explained in paragraph (d)(1)(ii). For purposes of this paragraph, the indexing year is never earlier than the second year before the year of your death. Except for this limitation, the indexing year is the earlier of -

(1) 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.

(2) For computing old-age insurance benefits and survivors insurance benefits, we subtract 5 from the number of your elapsed years. See paragraphs (e) (3) and (4) of this section for the dropout as applied to disability benefits. This is the number of your benefit computation years; we use the same number of your computation base years (see paragraph (b)(2) of this section) in computing your average indexed monthly earnings. For benefit computation years, we use the years with the highest amounts of earnings after indexing. They may include earnings from years that were not indexed, and must include years of no earnings if you do not have sufficient years with earnings. You cannot have fewer than 2 benefit computation years.

(3) Where the worker is first entitled to disability insurance benefits (DIB) after June 1980, there is an exception to the usual 5 year dropout provision explained in paragraph (e)(2) of this section. (For entitlement before July 1980, we use the usual dropout.) We call this exception the disability dropout. We divide the elapsed years by 5 and disregard any fraction. The result, which may not exceed 5, is the number of dropout years. We subtract that number from the number of elapsed years to get the number of benefit computation years, which may not be fewer than 2. After the worker dies, the disability dropout no longer applies and we use the basic 5 dropout years to compute benefits for survivors. We continue to apply the disability dropout when a person becomes entitled to old-age insurance benefits (OAIB), unless his or her entitlement to DIB ended at least 12 months before he or she became eligible for OAIB. For first DIB entitlement before July 1980, we use the rule in paragraph (e)(2) of this section.

(4) For benefits payable after June 1981, the disability dropout might be increased by the child care dropout. If the number of disability dropout years is fewer than 3, we will drop out a benefit computation year for each benefit computation year that the worker meets the child care requirement and had no earnings, until the total of all dropout years is 3. The child care requirement for any year is that the worker must have been living with his or her child (or his or her spouse's child) substantially throughout any part of any calendar year that the child was alive and under age 3. In actual practice, no more than 2 child care years may be dropped, because of the combined effect of the number of elapsed years, 1-for-5 dropout years (if any), and the computation years required for the computation.

(1) Totalling your indexed earnings in your benefit computation years;

(2) Dividing the total by the number of months in your benefit computation years; and

(3) Rounding the quotient to the next lower whole dollar. if not already a multiple of $1.
