This calculator helps estimate your Monthly Housing Allowance (MHA) based on your GI Bill eligibility and location. The MHA is a crucial part of your Post-9/11 GI Bill benefits, designed to help cover the cost of living off-campus or while pursuing your education.
The Post-9/11 GI Bill provides financial support to eligible service members, veterans, and their families pursuing higher education. A significant portion of this benefit is the Monthly Housing Allowance (MHA), which is intended to help offset the costs associated with living expenses while enrolled in school.
The MHA rate is determined by several factors:
Location: The primary determinant of your MHA is the Basic Allowance for Housing (BAH) rate for the zip code where you physically attend the majority of your classes. These rates are set by the Department of Defense and vary significantly by geographic area to reflect local housing costs.
Pay Grade: Your military pay grade influences the MHA. Generally, higher pay grades receive a higher allowance.
Dependents: If you have dependents (spouse and/or children), your MHA rate will be increased. The amount of the increase depends on the number of dependents you have.
School Type: For those attending schools in the U.S., the MHA is paid at the "with dependent" rate if you have dependents, regardless of whether you actually have them. For those attending schools outside the U.S., the MHA is paid at the "without dependent" rate. This calculator assumes you are attending a school within the U.S.
Tuition and Fees: If your tuition and fees are paid in full by another government entity (like the Department of Defense Tuition Assistance Program), you will not receive the MHA.
Disclaimer: This calculator provides an estimation based on publicly available BAH data and general GI Bill rules. Actual MHA amounts may vary. For the most accurate and official information, please consult the Department of Veterans Affairs (VA) or your educational institution's VA certifying official.
