Example: Ms. A reaches age 62 in July 1979. Her year-by-year social security earnings since 1950 are as follows:
Year | Earnings |
1951 | $3,200 |
1952 | 3,400 |
1953 | 3,300 |
1954 | 3,600 |
1955 | 3,700 |
1956 | 3,700 |
1957 | 4,000 |
1958 | 4,200 |
1959 | 4,400 |

1965 | 3,700 |
1966 | 4,500 |
1967 | 5,400 |
1968 | 6,200 |
1969 | 6,900 |
1970 | 7,300 |

1977 | 9,900 |
1978 | 11,000 |
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:
Year | I. 1977 general wage level | II. Nationwide average of the total wages | III. Column I divided by column II equals relationship |
1951 | $9,779.44 | $2,799.16 | 3.4937053 |
1952 | 9,779.44 | 2,973.32 | 3.2890641 |
1953 | 9,779.44 | 3,139.44 | 3.1150269 |
1954 | 9,779.44 | 3,155.64 | 3.0990354 |
1955 | 9,779.44 | 3,301.44 | 2.9621741 |
1956 | 9,779.44 | 3,532.36 | 2.7685287 |

1972 | 9,779.44 | 7,133.80 | 1.3708599 |
1973 | 9,779.44 | 7,580.16 | 1.2901364 |

1977 | 9,779.44 | 9,779.44 | 1.0000000 |
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:

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.
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.
