The Short Version
BAH means Basic Allowance for Housing. It is tax-free housing pay for off-post living. It rises with rank and dependents and changes by geography. It is not 100% of local rent.
Use the BAH calculator for your zip instead of last year's rumor mill.
- Three inputs: Pay grade, with/without dependents, and Military Housing Area (MHA).
- 95% standard: Since 2015 you are expected to cover about 5% out of pocket on a typical rate.
- Rate protection: Your personal rate does not fall while you stay in place continuously.
What BAH Is (and Is Not)
BAH is paid when you are not in government quarters. It is not taxable. It is not a promise that every house on Zillow is affordable.
Translate the monthly number into rent or a mortgage payment plus taxes and insurance, then leave margin for utilities and maintenance.
How the Rate Is Built
- Pay grade: Higher grades get higher rates.
- Dependency status: With-dependents rates are higher, often by hundreds a month depending on location.
- Zip / MHA: San Diego and Fort Drum are not the same housing market.
Rates update each January. Under rate protection, your personal BAH does not drop while you remain continuously at the same station. A PCS ends that protection. Promotion never lowers your rate.
How Much House Does That Buy?
Take your with-dependents BAH. Subtract a utilities estimate of $200 to $400 depending on climate and home size. What remains is the rent or principal-interest-taxes-insurance target.
With a VA loan and no PMI, some families fit a purchase payment under BAH and pocket the difference. Others discover the market is simply above the allowance.
Run buy vs rent vs on-base in this comparison and read before you buy.
Tour length still matters. Three-plus years often supports buying. Short tours usually favor renting after transaction costs. Pending NDAA fights over temporary BAH authority do not rewrite your current table. See the FY2027 NDAA explainer.
Common Mistakes
- Forgetting to update DEERS after marriage and missing with-dependents BAH.
- Spending to the ceiling with no maintenance or utility cushion.
- Ignoring that BAH ends the day you separate. Retirees: read retirement real estate.
What to Do Next
- Look up your current and gaining-station rates in the BAH calculator.
- Subtract utilities and a small maintenance cushion before you size rent or a mortgage.
- Confirm DEERS dependency status is current.
- Prefer the live calculator and official DTMO tables over any memorized dollar amount.
