Understanding Your GI Bill Housing Allowance
The Post-9/11 GI Bill and the Montgomery GI Bill (MGIB) provide significant educational benefits to eligible servicemembers and veterans. A crucial component of these benefits is the housing allowance, which is designed to help offset the costs associated with living while pursuing education. This calculator helps you estimate your potential monthly housing allowance, commonly referred to as the Basic Allowance for Housing (BAH) or the Monthly Housing Allowance (MHA).
How the GI Bill Housing Allowance is Calculated:
The calculation of your GI Bill housing allowance primarily depends on several factors:
Your Benefit Tier: This refers to the percentage of your Post-9/11 GI Bill benefits you are eligible for, or if you are using the Montgomery GI Bill. Higher benefit tiers generally result in a higher allowance.
Your Location (Zip Code): The U.S. Department of Defense sets BAH rates based on geographic location, with higher cost-of-living areas receiving a larger allowance. We use your provided zip code to find the appropriate rate.
Your Training Type: Whether you are training at a half-time or greater rate of pursuit is critical for Post-9/11 GI Bill recipients. For those attending more than half-time, the allowance is typically based on the zip code of the school or place of training. For those attending less than half-time, or for distance learning, specific rules apply and may differ. For simplicity, this calculator assumes training at a rate of pursuit that qualifies for the full BAH based on location.
Tuition, Fees, and Other Costs: While your direct housing allowance is primarily determined by location and benefit tier, other educational costs (like tuition, fees, and books) are handled separately by the VA. Some students may receive a lump sum for books and supplies, and tuition/fees are paid directly to the institution or reimbursed. The housing allowance is paid directly to the student.
Post-9/11 GI Bill (Chapter 33):
For Post-9/11 GI Bill recipients training at more than a half-time rate, the monthly housing allowance is generally paid to the student and is equal to the national average BAH for an E-5 with dependents. However, the VA uses the zip code of the school where you are enrolled to determine the specific rate. If you are training entirely online, you will receive 50% of the national average BAH.
The rate is also adjusted based on your benefit percentage (e.g., 100%, 90%, 80%).
Montgomery GI Bill (MGIB – Chapter 30):
MGIB recipients receive a monthly stipend that is not directly tied to their housing costs or zip code in the same way as the Post-9/11 GI Bill. The amount is fixed based on the number of months of training and the individual's rate of pursuit (full-time, 3/4 time, etc.). This calculator simplifies by providing a placeholder if MGIB is selected, as the calculation is fixed and not dependent on external data like BAH rates.
Using the Calculator:
To get an estimate:
Enter your current monthly rent or mortgage payment (this is for context and does not directly calculate your BAH, but helps understand your out-of-pocket costs).
Enter any significant monthly tuition, fees, or training costs. This helps you see the total financial picture.
Provide your zip code where you reside while attending school.
Select your GI Bill benefit tier or if you are using the Montgomery GI Bill.
The calculator will then estimate your monthly housing allowance. Remember, this is an approximation. For precise figures, always consult the official GI Bill Comparison Tool on the Department of Veterans Affairs website or contact the VA directly.
