Social Security: Cost-of-Living Adjustments
Summary
To compensate for the effects of inflation, Social Security recipients received cost-of-living
adjustments (COLAs) through the legislative process sporadically from 1950 to 1974, and
automatically through a trigger mechanism in each yearall but two years from 1975 to 20092012. No adjustment was
was made in 2010 and 2011, but benefits will increase by . Benefits will be increased by 1.7% in 2013, after an increase of
3.6% in 2012. 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
that can trigger a change. The Social
Security COLA is based on the percentage change in the
index from the highest third calendar
quarter average CPI-W recorded (most often, from the
previous year) to the average CPI-W for
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 payments always
reflect the benefits due for the preceding month.) If there
is no percentage increase in the CPI-W
between the measuring periods, no COLA is payable.
No COLA was payable in January 2010 because the average CPI-W for the third quarter of 2009
did not increase from the average CPI-W for the third quarter of 2008, and again in 2011 because
the average CPI-W for the third quarter of 2010 remained below the average CPI-W for the third
quarter of 2008. BecauseWhen the average CPI-W for the third quarter of 2011 has exceeded that for
2008, a COLA (3.6%) is payable in 2012.
Because a COLA of 3.6 2008 by
3.6%, establishing a new benchmark, a COLA was payable in 2012. Because the average CPI-W
for the third quarter of 2012 exceeded the average CPI-W for the third quarter of 2011 by 1.7%,
the COLA for 2013 will be 1.7%.
Because a COLA of 1.7% will be paid to Social Security beneficiaries in 20122013, identical
percentage increases in Supplemental Security Income (SSI) and railroad retirement “tier 1”
benefits will be paid, and other changes in the Social Security program will be triggered.
Although COLAs under the federal Civil Service Retirement System (CSRS) and the federal
military retirement program are not triggered directly by the Social Security COLA, these
programs use the same measuring period and formula for computing their COLAs. As a result,
their recipients similarly will receive a 3.61.7% COLA in January 20122013.
The Congressional Budget Office (CBO) and the trustees for the Social Security trust funds both
project a return to annual COLAs beyond 20122013.
This report is updated annually.

Social Security: Cost-of-Living Adjustments
How the Social Security COLA Is Determined
An automatic Social Security benefit increase reflects the rise in the cost of living over roughly a
one-year period. The Consumer Price Index for Urban Wage Earners and Clerical Workers
(CPI-W), updated monthly by the Bureau of Labor Statistics (BLS), is the measure that can
trigger a benefit adjustment. The Social Security cost-of-living adjustment (COLA) is based on
the percentage change in the index from the highest third calendar quarter average CPI-W
recorded (most often, from the previous year) to the average CPI-W for the third calendar quarter
of the current year. If the CPI-W triggers a COLA, the COLA becomes effective in December of
the current year and is payable in January of the following year. (Social Security payments always
reflect the benefits due for the preceding month.). A COLA trigger mechanism was first adopted
in in
P.L. 92-603, the Social Security Amendments of 1972, and triggered COLAs were first payable
in in
1975.
The January 20122013 COLA
On October 19, 201116, 2012, BLS announced the September 20112012 monthly CPI-W figure, making it
official that there would be a 3.61.7% Social Security COLA in January 2012, the first COLA in
three years2013. The release of the
September 20112012 index amount made the comparison of the two
July-September sets of CPI-W
figures needed to compute the COLA (one for 20082011 and another
for 20112012) possible. Table 1
shows how the January 20122013 COLA is computed under procedures set
forth in Section 215(i) of
the Social Security Act.

Social Security: Cost-of-Living Adjustments
Scenario In Which No COLA Is Payable
The Social Security Act specifies that a COLA is payable automatically if there is an increase in
the average CPI-W for the third quarter of the current year relative to the average CPI-W for the
third quarter of the year in which the “cost-of-living computation quarter” was established. The
cost-of-living computation quarter is the third quarter with the historical and present highest
average CPI-W. From 1975, when this provision became effective, to 2008, a new cost-of-living
computation quarter was established in each subsequent year, which triggered the payment of a
COLA each year.
However, it is possible to have one or more years in which no COLA is payable. If the average
CPI-W for the third quarter of the current year is equal to or less than the average CPI-W for the
cost-of-living computation quarter, no COLA is payable.
For example, when the average CPI-W for the third quarter of 2009 was reported to be less than
the average CPI-W
for the third quarter of 2008 (211.011001 and 215.495, respectively). As a result, the , the
authority to pay
an automatic COLA in January 2010 was not triggered.1
Because the average CPI-W for the third quarter of 2009 was less than the average CPI-W for the
third quarter of 2008, and the third quarter of 2008 remained the
cost-of-living computation quarter
(i.e., the benchmark) that was used to determine the COLA if a COLA would be
payable in January 2011.2 When the
1 Though the average CPI-W for the third quarter of 2010 was reported to be less(214.136) was
greater than the average CPI-W for
the third quarter of 2008, a COLA was not payable in January 2011, even though it was greater
than2009, it did not exceed the average CPI-W
for the third quarter of 2009. Now that2008. The third quarter of 2008 remained the cost-of-living computation
quarter for at least one more year and a COLA was not payable in January 2011.
When the average CPI-W for the third
quarter of 2011 has(223.233) exceeded that for 2008, a 2012
COLA was triggered and the third quarter of 2011 becomesbecame the cost-of-living
computation quarter. In other words, the COLA for 2013 will be based on the percentage increase
in
Now that the average CPI-W from the third quarter of 2011 to the third quarter of 2012.
Social Security benefit amounts can not be reduced if the CPI-W decreases between the
measuring periods. If the performance of the CPI-W does not trigger a COLA, benefits remain
the same (prior to deductions for Medicare Part B and Part D premiums). However, in the
absence of a COLA, changes in Medicare premiums may result in a net reduction in the Social
Security payment amount. In addition, regardless of the effect of a COLA, beneficiaries could see
a decrease in their net payment amount from year to year as a result of changes in their Medicare
Part D selections and the associated premiums.3

for the third quarter of 2012 has exceeded that for the third quarter
of 2011, the index for the 2012 measuring period will be used as the benchmark for a possible
COLA in 2014.2 See Table 2 for a recent history of average CPI-W performance for the third
calendar quarter, and how that has affected changes to the cost-of-living computation quarter and
the triggering of COLA payments in some years.

Section 215(i) of the Social Security Act specifies that no COLA is payable in subsequent years until the average
CPI-W for the third quarter of the current year is greater than that for the last cost-of-living computation quarter.

The Congressional Budget Office (CBO) and the trustees for the Social Security trust funds both project a return tocontinued
annual COLAs beyond 20122013. For more information, see CBO, The Budget and Economic Outlook: An Update, August

Social Security benefit amounts cannot be reduced if the CPI-W decreases between the
measuring periods. If the performance of the CPI-W does not trigger a COLA, benefits remain
the same (prior to deductions for Medicare Part B and Part D premiums). Most beneficiaries are
also protected from a net reduction in Social Security cash benefits that would be attributed to a
scheduled Medicare Part B premium increase, if there is no COLA payable or if the Medicare
Part B premium increase would exceed the dollar value of an applied COLA. However,
regardless of the triggering of a COLA, beneficiaries could see a decrease in their net payment
amount from year to year as a result of changes in their Medicare Part D selections and the
associated premiums.3
What Is Affected Besides Social Security Benefits?
Social Security COLAs trigger increases in other programs. Supplemental Security Income (SSI)
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 an amount equivalent to 32.5% of the
Social Security COLA. Veterans’ pension benefits most often are increased in the same amount as
Social Security, but legislation must be passed annually for this purpose.4 Although COLAs under
the Civil Service Retirement System (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 determining their COLAs. As a result, their recipients will also receive a 3.61.7% COLA
in January 2012.5

As of November 1, 2012, legislation providing a COLA for veterans’ benefits in 2013 has not been passed by both
chambers of Congress and signed into law by the President.

For retirees under the Federal Employees’ Retirement System (FERS), a different formula is applied and the resulting
increases may differ. For more information on the adjustment of federal program benefits for inflation, see CRS Report

Social Security: Cost-of-Living Adjustments
When a COLA is payable, other Social Security program elements are affected. For example, the
taxable earnings base and, the retirement earnings test (RET) exempt amounts can only be
, and the substantial
gainful activity (SGA) earnings level for the blind (Social Security disability beneficiaries) can
only be increased when a COLA is payable. Though changes to the taxable earnings base and the RET
exempt amounts, the
RET exempt amounts, and the SGA limit for the blind are based on the percentage increase in
national average wages (whereas the
CPI-W reflects changes in prices), they are linked to the
payment of a COLA. If a COLA is
payable, then these amounts increase by the percentage that
the national average wage index has
increased. If no COLA is payable, these amounts remain
unchanged, even if the national average
wage index experiences positive growth.6 The taxable
earnings base and, the RET exempt
amounts amounts, and the SGA for the blind had been frozen in 2010 and
2011 when no COLA was payable, but will increase in
2012were increased in 2012 and will increase again in 2013.7
Although not linked to the COLA, other changes are tied to the increase in national average
wages. These provisions include the amount of earnings needed for a Social Security “quarter-ofcoverage,” the monthly substantial gainful activity amounts for non-blind and blind Social
Security Social Security
disability beneficiaries, and the annual coverage thresholds for domestic workers and
election election
workers. These amounts may be altered even if a COLA is not payable.
Table 2 shows the history of increases in Social Security benefits.

As of October 19, 2011, legislation providing a COLA for veterans’ benefits in 2012 has not been passed and enacted
into law.

For retirees under the Federal Employees’ Retirement System (FERS), a different formula is applied and the resulting
increases may differ. For more information on the adjustment of federal program benefits for inflation, see CRS Report
