BAH is an allowance to offset the cost of housing when you do not receive government-provided housing. Your BAH depends upon your location, pay grade and whether you have dependents. BAH rates are set by surveying the cost of rental properties in each geographic location. The rates are established such that members in each pay grade, independent of location, pay approximately the same out-of-pocket costs. Therefore, BAH rates in high-cost areas will be much greater than those in low-cost areas. BAH rates are published on the Per Diem Committee web page
