Social Security: The Cost-of-Living
Adjustment in January 2003
David Koitz and Geoffrey Kollmann
Updated by Gary Sidor
Domestic Social Policy Division
Summary
To compensate for the effects of inflation, Social Security recipients receive a cost-
of-living adjustment (COLA) in January of each year. The Consumer Price Index for
Urban Wage Earners and Clerical Workers (CPI-W), updated monthly by the
Department of Labor’s Bureau of Labor Statistics (BLS), is the measure used to compute
the change. The Social Security COLA is based on the percentage change in the average
CPI-W for the third calendar quarter of the previous year to the third calendar quarter
of the current year. The COLA becomes effective in December of the current year and
is payable in January of the following year (Social Security checks always reflect the
benefits due for the preceding month).
The 1.4% COLA payable in January 2003 was triggered by the rise in the CPI-W
from the third quarter of 2001 to the third quarter of 2002. This COLA triggers identical
percentage increases in Supplemental Security Income (SSI), veterans’ pensions, and
railroad retirement benefits, and causes other changes in the Social Security program.
Although COLAs under the federal Civil Service Retirement System (CSRS) and the
federal military retirement program are not triggered by the Social Security COLA, these
programs use the same measuring period and formula for computing their COLAs.
Their recipients also receive a 1.4% COLA in January 2003. This report is updated
annually.
How the Social Security COLA Is Determined
An automatic Social Security benefit increase reflects the rise in the cost of living
over roughly a 1-year period. The CPI-W, updated monthly by the BLS, is the measure
used to compute the change. The Social Security COLA is based on the percentage
change in the average CPI-W for the third calendar quarter of the previous year to the
third calendar quarter of the current year. The COLA becomes effective in December of
the current year and is payable in January of the following year (Social Security checks
always reflect the benefits due for the preceding month).

The January 2003 COLA
The January 2003 COLA became known on October 18, 2002, when the BLS
announced the September 2002 CPI-W figure. With release of the September 2002 index,
the two July-September sets of CPI-W figures needed to compute the COLA (one for
2001 and another for 2002) became available. Table 1 shows how the January 2003
COLA is computed under procedures set forth in section 215(i) of the Social Security Act.

What Else Is Affected Besides Social Security Benefits?
Social Security COLAs trigger increases in other programs. SSI benefits, veterans’
pension benefits, and railroad retirement “tier 1” benefits (equivalent to a Social Security
benefit) are increased by the same percentage as the Social Security COLA. Railroad
retirement “tier 2” benefits (equivalent to a private pension) are increased by 32.5% of the
percentage increase applicable to “tier 1” COLAs. Although COLAs under the CSRS and
the federal military retirement system are not triggered by the Social Security COLA,
these programs use the same measuring period and formula for computing their COLAs.
Their recipients also receive a 1.4% COLA in January 2003.1 The COLA also triggers

applied and the resulting increases may differ.

other changes in the Social Security program including the following items indexed to the
increase in national average wages:
Taxable earnings base. The Social Security (or Old-Age, Survivors, and Disability
Insurance — OASDI) taxable earnings base (the maximum amount of annual earnings
subject to Social Security taxes) will increase to $87,000 in 2003 (from $84,900 in 2002).
Exempt amounts under the Social Security earnings test. The exempt amount under
the earnings test (the maximum annual amount a Social Security recipient can earn from
work and still receive full benefits) will rise to $11,520 in 2003 (up from $11,280 in
2002) for persons who are below the full retirement age (FRA) and will not reach the
FRA during the year. For those born prior to 1937, the FRA is 65 years. For those born
in 1938, it is 65 years and two months. According to law, the FRA will gradually increase
to eventually reach 66 years for those born between 1943 and 1954, and 67 years for those
born in after 1959. The ages at which the earnings test applies will increase accordingly.
Under the Senior Citizens’ Freedom to Work Act (P.L. 106-182), effective January 1,
2000, the earnings test no longer applies to recipients beginning in the month they reach
the FRA. During the year in which a recipient reaches the FRA, an annual exempt
amount still applies for months preceding the attainment of the FRA. Under the law, the
exempt amount will be $30,720 in 2003 (up from $30,000 in 2002), and will continue to
rise in proportion to the increase in national average wages.
Although not triggered by COLAs, other changes are tied to the increase in national
average wages. In 2003, the amount of earnings needed for a Social Security “quarter-of-
coverage” is $890 (up from $870 in 2002). The coverage threshold for domestic workers
is $1,400 (up from $1,300 in 2002), while the threshold for election workers remains
unchanged at $1,200. The monthly substantial gainful activity amount for the non-blind
disabled is $800 (up from $780 in 2002), and the amount for the blind disabled is $1,330
(up from $1,300 in 2002).
Tables 2 and 3 show the history of increases in Social Security benefits and the
taxable earnings base. Table 4 shows the effect of the January 2003 COLA on monthly
benefit levels.

a The HI taxable earnings base was eliminated by the Omnibus Budget Reconciliation
Act of 1993. In 1991, it was raised to $125,000 as a revenue-raising measure in
the Omnibus Budget Reconciliation Act of 1990.
b 1966 was first year in which the HI tax was levied.
