Military Cost-of-Living Allowances Need Stronger Data and Clearer Communication

The U.S. Government Accountability Office’s April 2026 report, Military Personnel: DOD Should Improve Processes for Determining Cost-of-Living Allowances, examines whether the Department of Defense’s cost-of-living allowance programs adequately reflect the financial realities faced by service members stationed in high-cost locations. Giving credit to GAO and its audit team, led by Rashmi Agarwal, the report provides a detailed assessment of the methodology DOD uses to calculate allowances for service members in both the continental United States and outside the continental United States. Its central conclusion is that DOD has a functioning COLA framework, but several weaknesses in data collection, sampling, location-specific cost recognition, dependent compensation, and communication may affect whether service members are being appropriately compensated.

DOD assigns approximately 1.4 million active-duty service members to more than 3,500 locations worldwide. Some of these locations, including Washington, D.C., Hawaii, Alaska, Germany, and Japan, impose higher living costs on military families. To address these differences, DOD administers separate CONUS and OCONUS COLA programs. These allowances are intended to offset nonhousing expenses, such as food, transportation, clothing, and other goods and services. In calendar year 2024, nearly 225,000 service members received more than $1.2 billion in OCONUS COLA, while approximately 25,000 received about $33 million in CONUS COLA.

GAO explains that DOD relies on three principal inputs to calculate COLA rates. First, DOD uses Bureau of Labor Statistics data to identify 150 nonhousing goods and services that reflect typical military household spending. Second, DOD uses a Living Pattern Survey to determine where service members shop, including on base, off base, and online. Third, DOD uses a Retail Price Schedule to collect prices for those goods and services in specific locations. DOD then compares location-specific prices to the average CONUS price baseline to determine whether a location qualifies for COLA and, if so, the applicable rate.

The report identifies several weaknesses. The most significant is that DOD’s Living Pattern Survey does not use sound sampling practices. DOD relies on quota sampling and accepts responses from anyone who completes the survey, rather than using random sampling to obtain statistically representative results. GAO found that this approach can overrepresent certain subgroups and may allow ineligible or duplicate responses. As a result, the survey may not accurately reflect actual service member shopping patterns.

GAO also found that DOD does not consistently capture location-specific expenses. This matters because some locations impose unusual costs that may not be reflected in ordinary price surveys. For example, service members reported high utility expenses in Hawaii and Alaska, drinking water costs in Hawaii, and other transportation or climate-related costs in OCONUS locations. Although DOD has a process for addressing unique expenses, GAO found that it is not applied consistently.

The report also raises concerns about differences between CONUS and OCONUS dependent-based compensation. OCONUS COLA considers the number of dependents, while CONUS COLA treats dependent status largely as a yes-or-no variable. This inconsistency may produce different outcomes for similarly situated families. GAO also found that service members do not always understand why their COLA changes, particularly when OCONUS rates fluctuate due to currency movements or updated cost data.

GAO made four recommendations: use random sampling for shopping-pattern surveys, consistently apply the process for location-specific expenses, consider aligning CONUS and OCONUS dependent compensation, and require local commands to provide clearer COLA information. DOD concurred with some recommendations, partially concurred with one, and non-concurred with the random sampling recommendation. GAO maintained that the recommendation remains valid because DOD’s current approach does not produce statistically representative results.

The broader lesson is that compensation policy depends on credible data and clear communication. For service members, COLA is not an abstraction; it affects family budgets, quality of life, retention, and readiness. A more rigorous and transparent COLA process would better support the people asked to serve in expensive and often difficult locations.
