              Subpart C_Computing Primary Insurance Amounts
 
Sec. 404.211  Computing your average indexed monthly earnings.

    (a) General. In this method, your social security earnings after 
1950 are indexed, as described in paragraph (d) of this section, then 
averaged over the period of time you can reasonably have been expected 
to have worked in employment or self-employment covered by social 
security. (Your earnings before 1951 are not used in finding your 
average indexed monthly earnings.)
    (b) Which earnings may be used in computing your average indexed 
monthly earnings--(1) Earnings. In computing your average indexed 
monthly earnings, we use wages, compensation, self-employment income, 
and deemed military wage credits (see Sec. Sec. 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 Sec. Sec. 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.
    (c) Average of the total wages. Before we compute your average 
indexed monthly earnings, we must first know the ``average of the total 
wages'' of all workers for each year from 1951 until the second year 
before you become eligible. The average of the total wages for years 
after 1950 are shown in appendix I. Corresponding figures for more 
recent years which have not yet been incorporated into this appendix are 
published in the Federal Register on or before November 1 of the 
succeeding year. ``Average of the total wages'' (or ``average wage'') 
means:
    (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.
    (d) Indexing your earnings. (1) The first step in indexing your 
social security earnings is to find the relationship (under paragraph 
(d)(2) of this section) between--
    (i) The average wage of all workers in your computation base years; 
and
    (ii) The average wage of all workers in your indexing year. As a 
general rule, your indexing year is the second year before the earliest 
of the year you reach age 62, or become disabled or die before age 62. 
However, your indexing

[[Page 73]]

year is determined under paragraph (d)(4) of this section if you die 
before age 62, your surviving spouse or surviving divorced spouse is 
first eligible for benefits after 1984, and the indexing year explained 
in paragraph (d)(4) results in a higher widow(er)'s benefit than results 
from determining the indexing year under the general rule.
    (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 Sec. Sec. 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.)

    Example: Ms. A reaches age 62 in July 1979. Her year-by-year social 
security earnings since 1950 are as follows:

    Step 1. The first step in indexing Ms. A's earnings is to find the 
relationship between the general wage level in Ms. A's indexing year 
(1977) and the general wage level in each of the years 1951-1976. We 
refer to appendix I for average wage figures, and perform the following 
computations:

------------------------------------------------------------------------

    Step 2. After we have found these indexing quotients, we multiply 
Ms. A's actual year-by-year earnings by them to find her indexed 
earnings, as shown below:

                                                                 III.

    (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--
    (i) The year in which you, the insured worker, attained age 60, or 
would have attained age 60 if you had lived, and
    (ii) The second year before the year in which the surviving spouse 
or the surviving divorced spouse becomes eligible for widow(er)'s 
benefits, i.e. has attained age 60, or is age 50-59 and disabled.
    (e) Number of years to be considered in finding your average indexed 
monthly earnings. To find the number of years to be used in computing 
your average indexed monthly earnings--
    (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 Sec. 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

[[Page 75]]

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.

    Example: Ms. M., born August 4, 1953, became entitled to disability 
insurance benefits (DIB) beginning in July 1980 based on a disability 
which began January 15, 1980. In computing the DIB, we determined that 
the elapsed years are 1975 through 1979, the number of dropout years is 
1 (5 elapsed years divided by 5), and the number of computation years is 
4. Since Ms. M. had no earnings in 1975 and 1976, we drop out 1975 and 
use her earnings for the years 1977 through 1979.
    Ms. M. lived with her child, who was born in 1972, in all months of 
1973 and 1974 and did not have any earnings in those years. We, 
therefore, recompute Ms. M.'s DIB beginning with July 1981 to give her 
the advantage of the child care dropout. To do this, we reduce the 4 
computation years by 1 child care year to get 3 computation years. 
Because the child care dropout cannot be applied to computation years in 
which the worker had earnings, we can drop only one of Ms. M.'s 
computation years, i.e., 1976, in addition to the year 1975 which we 
dropped in the initial computation.

    (i) Living with means that you and the child ordinarily live in the 
same home and you exercise, or have the right to exercise, parental 
control. See Sec. 404.366(c) for a further explanation.
    (ii) Substantially throughout any part of any calendar year means 
that any period you were not living with the child during a calendar 
year did not exceed 3 months. If the child was either born or attained 
age 3 during the calendar year, the period of absence in the year cannot 
have exceeded the smaller period of 3 months, or one-half the time after 
the child's birth or before the child attained age 3.
    (iii) Earnings means wages for services rendered and net earnings 
from self-employment minus any net loss for a taxable year. See Sec. 
404.429 for a further explanation.
    (f) Your average indexed monthly earnings. After we have indexed 
your earnings and found your benefit computation years, we compute your 
average indexed monthly earnings by--
    (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.

    Example: From the example in paragraph (d) of this section, we see 
that Ms. A reaches age 62 in 1979. Her elapsed years are 1951-1978 (28 
years). We subtract 5 from her 28 elapsed years to find that we must use 
23 benefit computation years. This means that we will use her 23 highest 
computation base years to find her average indexed monthly earnings. We 
exclude the 5 years 1961-1965 and total her indexed earnings for the 
remaining years, i.e., the benefit computation years (including her 
unindexed earnings in 1977 and 1978) and get $249,381.41. We then divide 
that amount by the 276 months in her 23 benefit computation years and 
find her average indexed monthly earnings to be $903.56, which is 
rounded down to $903.
