*This is an estimation based on regional MHA (Military Housing Area) averages. Rates for 2025 are projected based on historical 3.5% inflation adjustments.
What is the DoD BAH?
The Basic Allowance for Housing (BAH) is a U.S. based entitlement prescribed by geographic duty location, pay grade, and dependency status. It provides uniformed service members equitable housing compensation based on housing costs in local civilian housing markets when government quarters are not provided.
How BAH Rates Are Calculated
The Department of Defense (DoD) determines BAH rates by analyzing current rental market data in approximately 300 Military Housing Areas (MHAs) across the United States. The calculation includes:
Median Rental Costs: Based on the type of housing assigned to each rank (e.g., apartments for lower enlisted, single-family homes for senior officers).
Average Utility Costs: Including electricity, heat, and water/sewer.
Dependency Status: Members with dependents receive a higher rate to accommodate larger living spaces.
BAH Rate Protection (Grandfathering)
One of the most important aspects of the BAH system is Individual Rate Protection. This ensures that if you are already stationed at a location and the BAH rates decrease, your allowance will not be lowered as long as you maintain eligibility (i.e., you do not have a reduction in pay grade or change in dependency status). If rates increase, you will receive the higher amount.
2024 vs. 2025 BAH Trends
BAH rates typically trend upward alongside the national rental market. In 2024, the DoD saw an average increase of roughly 5.4%. Projections for 2025 suggest a moderate stabilization, though high-growth areas like Florida, Texas, and California often see adjustments higher than the national average.
Factor
Impact on BAH
Promotion
Usually increases BAH rate.
PCS Move
Resets BAH to the new ZIP code's current rate.
Marriage/Child
Increases status to "With Dependents" rate.
Divorce
May revert to "Without Dependents" rate.
