Formula
BAH depends on pay grade, whether you have qualifying dependents, and housing cost for your duty area. This tool uses a simplified example table.
Worked Example
Understanding Basic Allowance for Housing (BAH)
- BAH rates vary by three main factors: pay grade, duty station location, and whether you have qualifying dependents
- Rates are recalculated annually based on rental market surveys conducted by the Department of Defense
- Service members with dependents receive a higher rate to account for the need for larger housing
- BAH is not taxable income, making it one of the most valuable components of military compensation
Use this estimator for budget planning, then confirm official rates through the Defense Travel Management Office or your finance office.
You can also calculate changes using our BAH by ZIP Code Calculator, Army BAH Calculator, BAH With Dependents Calculator, BAH by ZIP Code Calculator or BAS Calculator.
Frequently Asked Questions
Is this the official BAH rate calculator?
No. This tool estimates BAH using a simplified illustrative table. For official rates, use the Defense Travel Management Office BAH tools or your unit finance office.
What inputs change the BAH estimate most?
Pay grade, housing cost bucket for your duty area, and whether you qualify as having dependents. Those three factors drive the selected rate.
Does BAH increase for each additional child?
No. BAH treats dependent status as binary: with dependents or without dependents. The rate does not increase linearly per child after you qualify for the with-dependents rate.
Can I pocket the difference if my rent is less than BAH?
Yes. BAH is paid as a flat monthly allowance regardless of your actual housing costs. If you find housing below the BAH rate, you keep the difference.
Does BAH change when I PCS to a new duty station?
Yes. BAH is recalculated based on the housing costs at your new duty location. High-cost areas like San Diego or Washington D.C. have significantly higher rates than rural bases.
