One rate, not a per-person payment
Every BAH table has two columns: with dependents and without. There is no third column for two kids, no multiplier for a large family. One dependent unlocks the with-dependents rate, and the sixth dependent changes nothing. The logic is housing space: a member supporting a family needs more rooms than a member living alone, and that need does not scale with headcount.
The size of the bump varies by location because each column is priced from local rents. In the 2026 tables, an E-5 in San Diego draws $3,975 with dependents versus $3,147 without: an $828 monthly difference, or $9,936 a year (828 times 12). In Honolulu the same E-5 sees an $807 gap ($3,663 versus $2,856). In the DC metro area it is $300 ($3,132 versus $2,832), and in Panama City it is also $300 ($2,163 versus $1,863).
Who counts as a dependent
A spouse counts. Unmarried children under 21 count, and older children count if they are full-time students or incapable of self-support in the usual cases. Parents and parents-in-law can count if they are actually dependent on the member for over half their support. The common thread is legal dependency, not just family membership.
Dual-military couples
When both spouses serve, the rules prevent double-dipping. A dual-military couple with no children: each spouse draws the without-dependents rate. Add a child, and one spouse moves to the with-dependents rate while the other stays at the without rate. The couple cannot both draw the with-dependents rate for the same child. Which spouse takes the with-dependents column is the couple's choice, and the higher earner's grade usually wins the math.
Divorce, custody, and child support
Divorce does not automatically end the with-dependents rate. A member who pays child support generally keeps drawing the with-dependents rate, because the support obligation is the dependency the column recognizes. A member in government housing who pays child support is the classic partial BAH case: the barracks cover the member's own housing, so the payment shrinks to the differential, $8.70 a month for an E-5 or $22.20 for an O-3 in 2026. Custody arrangements can shift which parent holds the with-dependents rate, so update your dependency paperwork with finance promptly after any court order.
When the rate starts and stops
The with-dependents rate generally starts on the date the dependency begins: the date of marriage, or the birth or adoption of a child. It stops when the dependency ends, typically the date a divorce is finalized, unless a support obligation continues past it. When paperwork lags the real event, back pay usually covers the gap, which is why filing dependency updates with finance quickly matters. The reverse is also true: an overpayment from an unreported divorce gets collected from future pay, so accuracy protects your budget both ways.
Check your column
Family changes, marriage, divorce, a new baby, or a dual-military wedding, are exactly when members get this wrong. Look up both columns for your grade and location with the free BAH calculator and confirm you are in the right one. For the annual tables behind those numbers, read our 2026 BAH rates guide.
