This calculator helps you estimate your potential Basic Allowance for Housing (BAH) rate for 2025. BAH is a U.S. standard to provide uniformed service members with compensation to offset the costs of off-post housing. The rate varies based on your duty station, rank, years of service, and whether you have dependents.
The Basic Allowance for Housing (BAH) is a critical component of military compensation. It's designed to help service members cover the costs of living in civilian housing. The rates are determined annually by the Department of Defense and are location-specific. Key factors influencing your BAH rate include:
Duty Station: Housing costs vary significantly by geographic location. A ZIP code is used to pinpoint the relevant cost of living data.
Rank and Grade: Higher ranks generally receive higher BAH rates as they are expected to maintain a certain standard of living.
Years of Service: Longevity often correlates with increased pay and allowances, including BAH.
Dependency Status: Service members with dependents typically receive a higher BAH rate to accommodate larger housing needs.
It's important to note that BAH rates are calculated separately for those with and without dependents. The calculator provides an estimate based on the data you input. For the most accurate and official rates, always refer to the Department of Defense's official BAH rate tables, which are typically updated annually.
