The Cost of Operations in Iraq, Afghanistan,
and Enhanced Security
Amy Belasco

Summary
Since the 9/11 terrorist attacks, CRS estimates that the Department of Defense
(DOD) has received over $201 billion for combat operations, occupation, and support
for military personnel deployed or supporting operations in Iraq and Afghanistan and for
enhanced security at military installations, collectively called the “global war on
terrorism.” That includes $25 billion to cover some of DOD’s FY2005 costs. On
January 25, 2005, the White House announced it would request $80 billion more for
these operations in its FY2005 Supplemental, including about $75 billion for DOD. If
Congress approves that amount, DOD’s funding through FY2005 for these missions will
exceed $275 billion. Much of the debate about the new supplemental may focus on the
cost and duration of U.S. involvement in Iraq and the global war on terrorism. CBO
recently estimated that military operations in Iraq and Afghanistan could cost $458
billion from FY2005 through FY2014 in addition to amounts already received.
While the Defense Department has provided various data to the Congress, it has
not given Congress a full allocation of funding for Iraq, Afghanistan, and enhanced
security. Based on data from DOD, CRS estimates that DOD expected to spend about
$100 billion for Iraq, $50 billion for Afghanistan, and $23 billion for enhanced security
through the end of FY2004. Between FY2002 and FY2005, Congress appropriated
about $27 billion to other agencies for reconstruction and embassy operations in Iraq and
Afghanistan. With those costs, total funding would be about $148 billion for Iraq and
$58 billion for Afghanistan as of the end of the 108th Congress. If Congress approves
the $75 billion requested and if the cost for Afghanistan remains steady, CRS estimates
that DOD’s contractual costs could total about $192 billion for Iraq, about $58 billion
for Afghanistan, and about $20 billion for enhanced security by the end of FY2005.
Likely FY2005 Funding Compared to Previous Funding
According to press reports, the White House is likely to request an additional $75
billion to cover DOD’s FY2005 costs for Iraq, Afghanistan, and enhanced security, as

well as another $5 billion for other agencies.1 Adding the $25 billion in “bridge” funds
already appropriated to cover war costs in the first few months of the fiscal year, total
FY2005 funding for military operations in Iraq and Afghanistan and enhanced security
for defense installations would be about $98 billion, some $33 billion and 50% higher
than the $64.9 billion enacted for these purposes in FY2004 (See Table 1).2
Although details about the new supplemental are not yet available, the FY2005
request is likely to include substantial amounts for “reconstitution,” i.e. to repair and
replace damaged or destroyed equipment, as well as for new efforts to reconfigure Army
brigades to smaller, more easily deployed units of action. Debate about this new
supplemental may focus on the duration and overall cost of the U.S. occupation of Iraq.
According to a new CBO estimate, operations in Iraq and Afghanistan and enhanced
security for FY2005 through FY2014 could cost $458 billion in addition to the $201
billion that DOD has already received (see Table 1).3 CRS estimates that DOD can pay
for its operational war costs until at least the end of April 2005 by using the bridge
supplemental and FY2005 peacetime funds.4
Data Difficulties
The Defense Department has not provided an allocation of all of its war-related
appropriations since 9/11 which shows the amounts for individual operations in Iraq
(Operation Iraqi Freedom), Afghanistan (Operation Enduring Freedom), and enhanced
security for defense installations (Operation Noble Eagle). DOD’s funding is not
appropriated by military operation but rather by the type of expense, e.g. funds to pay
troops. Since the mid-1990s, however, DOD has captured estimates of the incremental
cost of contingencies and military operations in monthly reports issued by the Defense
Finance and Accounting Service (DFAS).5 CRS has relied on these DFAS reports, other
DOD data, and congressional appropriations reports to resolve discrepancies and fill in
gaps and estimate how costs are split among Iraq, Afghanistan, and enhanced security.

“Supplemental Request in the Wings,” January 31, 2005.
2 The $25 billion provided P.L. 108-287 was made available upon enactment to cover potential
shortfalls and hence is “scored” or counted as FY2004 funds. DOD obligated $1.8 billion in
FY2004 and will use the remaining $23.2 billion for FY2005 expenses.

Iraq and Afghanistan and in Support of the Global War on Terrorism,” February 1, 2005;
[http://www.cbo.gov/ftpdocs/60xx/doc6067/02-01-WarSpending.pdf].
4 CRS’s estimate for how long DOD can “cashflow” or finance war costs assumes that
operational costs this year will be similar to those in FY2004, and that the higher funding level
likely to be requested in FY2005 is largely due to more investment costs which can be delayed
in the short-term.
5 The services use DOD financial regulations as guides to distinguish between peacetime and
operations in their reports to DFAS but such allocations may require judgement calls; see
Volume 12, Chapter 23, “Contingency Operations,” in DOD Financial Management Regulation,
[http://www.defenselink.mil/comptroller/fmr/]; obligations reflect amounts DOD contracts to
spend rather than outlays, the actual amounts spent. DOD does not track outlays for
contingencies as it does for other spending.

CRS-3
If the Defense Department set up separate accounts for war and occupation expenses, both
its tracking and its predictive ability could improve.
DOD Funds for Afghanistan, Iraq, and Enhanced Security Total
Over $200 Billion Through the 108th Congress

Since September 11, 2001, the Department of Defense (DOD) has received over
$200 billion to cover the cost of combat, ongoing military operations, and occupation in
Afghanistan and Iraq, as well as enhanced security in the United States for defense
installations. These funds were provided in regular and supplemental appropriations
measures enacted between FY2001 and FY2005. If Congress approves the $75 billion
likely to be requested, then the DOD cost of the “global war on terrorism” would exceed
$275 billion through FY2005 (see Table 1 below).

a. Totals reflect DOD’s budgetary resources for war-related expenses and exclude funds transferred to other
agencies, contingent appropriations not approved, and rescissions to regular DOD appropriations and
include transfers from regular DOD funds.
b. CBO counted DOD’s FY2005 war-related appropriations as $26.8 billion, including $1.8 billion to
reflect Congress’s decision to no longer require that DOD rescind funds provided in FY2004 funds;
that action does not provide an additional $1.8 billion in resources and hence is not counted above.

DOD’s Projected Funding For Iraq, Afghanistan, and Enhanced
Security, FY2001-FY2005

Of the total of $201.2 billion in appropriations received by DOD through the 108th
Congress, DOD documents suggest that Iraq is expected to cost about $125 billion,
Afghanistan about $54 billion and enhanced security about $23 billion (see Table 2).6
Of that total, Afghanistan accounts for about 25%, Iraq for over 60% and enhanced
security just over 10%.

*Denotes CRS estimate
Sources and Notes: CRS calculations based on DOD data, congressional committee reports, and DOD briefings.
Totals may not add due to rounding. Include $14 billion in intelligence funding.
a. ‘Other’ includes funding for Pentagon reconstruction and reconstruction.
b CRS allocated monies for the “global war on terrorism,” assuming that military personnel and Operation and
Maintenance funds were for enhanced security (e.g. guards) and that procurement and Research Development, Test
& Evaluation funds were for Afghanistan (e.g. munitions); this also reflects project descriptions.
c Includes $4.6 billion in funds transferred from DOD’s regular appropriations for war-related costs. DOD did not specify
transfers or FY2005 funds by operation, so CRS split these transfers 85% for Iraq and 15% for Afghanistan based
on FY2004 obligations.
The cost estimates above reflect DOD’s forecasts about the pace of operations in Iraq
and Afghanistan and estimates of costs and appropriations received. Since most of the
FY2001 funding was appropriated at the very end of the fiscal year, it is appropriate to
combine FY2001 and FY2002, suggesting the cost for Afghanistan’s first year of
operations was $24.8 billion. In FY2003, after combat operations and the first year of
occupation were completed, DOD projected that the cost of Afghanistan would drop by
one-quarter to $18.4 billion. By FY2004, DOD expected that costs would more than
halve to $7.1 billion.
In the case of Iraq, DOD originally estimated that costs in FY2003 for Iraq would be
$52.0 billion to cover deployment of forces in the late fall of 2002, the conduct of major
combat operations in March 2003, and post-combat stabilization operations. Assuming

of funding provided in DOD’s regular FY2004, and FY2005 appropriations; see notes to Table
2 for more detail.

CRS-5
ten months of operating costs — based on the initial influx of troops for Iraq in December
2002 — that suggests that operations in FY2003 were expected to average about $5.2
billion a month. In FY2004, DOD expected monthly costs to drop to $4.3 billion, with
an annual cost of about $51 billion.7
DOD’s estimates of the cost of enhanced security vary for reasons that are not clear.
In the year immediately after the September 11th attacks when DOD ratcheted up security
at its bases and conducted extensive combat air patrol, DOD estimated costs at $6.1
billion. That cost was expected to increase to $9.6 billion in the following year FY2003.
Then in FY2004, DOD forecast that funding would drop to $7.1 billion, $1 billion more
than for the first year after the attacks.8
Trends in Obligations Reflect Unanticipated Changes
DOD obligations — funds contracted to be spent — show how and where costs were
incurred and, hence, are a more accurate reflection of circumstances.9 CRS estimates
suggest that total obligations through FY2004 for the “global war on terrorism,” were
over $7 billion less than the total amount appropriated through P.L. 108-106, the FY2004
supplemental appropriations act; according to DOD, both its appropriations and its
obligations for this period were about $171 billion.10 By the end of FY2004, DOD had
obligated a total of about $170 billion, including about $106 billion for Iraq, about $47
billion for Afghanistan, and about $18 billion for enhanced security.
Comparing overall obligations to enacted levels, Iraq has cost about $5 billion more,
Afghanistan about $3 billion less and enhanced security about $5 billion less than enacted
levels (see Table 2 and Table 3).11 In FY2003, obligations were lower than anticipated
for Iraq, Afghanistan and enhanced security, and in FY2004, obligations generally
exceeded forecasts.

Estimating - Funding - Execution,” February 2004, p. 6.
8 DOD’s official submit estimated the cost of enhanced security at $2.2 billion but its planning
documents assumed $7.1billion; see DOD, “FY2004 Supplemental Request . . .” above.
9 Obligations do not capture the full cost of equipment purchases because some contracts are not
negotiated until the second year after funds are appropriated.

of Defense (DoD) Terrorist Response Cost Report, September 2003 and September 2004, Congressional
reports, and DOD briefings.
Notes: Totals may not add due to rounding.
Iraq: Obligations vs. Forecast. Obligations data indicate that Iraq’s monthly
costs in FY2003 were about $4.4 billion, or about $800 million lower than the $5.2 billion
forecast, perhaps because initial combat costs were lower than expected. For this reason,
Congress rescinded $3.5 billion of the FY2003 supplemental. For FY2004, Iraq’s
monthly obligations were about $5.1 billion, about $800 million higher than the $4.3
billion forecast. Those higher costs reflected the fact that instead of dropping to 99,000
as anticipated, troop levels remained around 150,000; that combat operations intensified;
and that DOD faced unexpectedly high costs for force protection (e.g. uparmoring of
Humvees).12 To make up the shortfall in FY2004, DOD transferred $4.6 billion from its
peacetime funds and tapped $1.9 billion in funds appropriated in FY2005.13
Afghanistan: Obligations vs. Forecast. For Afghanistan, FY2003, obligations
were somewhat lower than planning figures, $16.2 billion rather than $18.1 billion. In
FY2004, obligations for Afghanistan were $11.0 billion rather than the $7.1 billion
forecast, about 50% higher than anticipated, which may reflect higher troop levels and
base support costs.14
Enhanced Security: Obligations vs. Forecast. In FY2003, obligations for
enhanced security were $6.3 billion compared to the $9.6 billion appropriated. This may
reflect both difficulties that DOD has experienced in tracking all funds appropriated for
the global war on terrorism and part of the gap between total appropriations and total
obligations. In FY2004, DOD obligated $3.9 billion for this mission rather than the $7.1
billion anticipated in its forecast. Lower costs may be due to efforts by the services to
reduce use of reservists for enhanced security on bases because of the increased demand
for those forces in Iraq.
