Prorated BAH: daily rate × covered days.
Housing cost share: rent + utilities + insurance + parking + other costs, divided by people sharing costs.
Monthly gap: housing cost share − applied monthly BAH.
Taxable equivalent: applied monthly BAH ÷ (1 − estimated tax rate).

BAH Rates Calculator Guide
The BAH Rates Calculator helps service members estimate housing support before a move, lease renewal, or budget review. BAH means Basic Allowance for Housing. The allowance changes by pay grade, dependency status, and assigned location. This tool does not replace the official table. It gives a planning estimate from the rate you enter or from the editable sample table inside the file.
Why This Calculator Helps
Housing choices can affect the monthly budget. A member may compare rent, utilities, insurance, parking, and expected out of pocket cost in one place. The calculator also shows annual allowance, daily proration, rent coverage, and a taxable income equivalent. These values make the housing decision clearer.
Planning With Rate Protection
Some members may have a protected prior rate. When rate protection is enabled, the calculator compares the current rate with the previous protected amount. It then uses the higher value for the estimate. This is useful when an area rate falls, but eligibility details stay the same. The calculator also lets you prorate results for partial months.
Inputs That Matter
Start with the year, pay grade, and dependency status. Then select an area from the sample lookup or enter a manual monthly rate. Add rent and other recurring housing costs. Enter covered days and days in the month if the allowance starts or ends midmonth. Add a tax rate if you want a taxable income comparison.
Reading The Results
The main result shows estimated monthly BAH. The rent gap shows whether housing costs are above or below the allowance. A positive gap means expected out of pocket cost. A negative gap means the allowance exceeds entered costs. Export options help save the calculation for records, planning notes, or adviser review.
Important Reminder
Always verify official rates before making financial commitments. Local rates can change each year. Dependency status and duty station rules can also affect eligibility. Use this calculator as a planning aid, not as final pay guidance. For final decisions, confirm the official published rate with the proper finance office.
FAQs
1. What does this BAH calculator estimate?
It estimates monthly and prorated housing allowance, rent coverage, yearly value, and possible out of pocket housing cost using your selected grade, dependency status, location, and entered expenses.
2. Are the included area rates official?
No. The included lookup values are editable sample values. Use manual mode or replace the sample array with official tables before publishing the tool for real decisions.
3. Can I use my exact official BAH rate?
Yes. Choose manual monthly rate and enter the official amount. The calculator will use that value instead of the sample lookup value.
4. What does rate protection mean here?
It compares the current estimated rate with a prior protected rate. If enabled, the calculator uses the higher amount for the result.
5. Why does the calculator ask for covered days?
Covered days allow a partial month estimate. This helps when a housing allowance begins, ends, or changes during the month.
6. What is the monthly gap?
The monthly gap compares your housing cost share with the applied monthly BAH. A positive gap means costs exceed the allowance. A negative gap means the allowance exceeds entered costs.
7. What is taxable income equivalent?
It estimates how much taxable income may be needed to equal the entered allowance after tax. It uses your estimated tax rate.
8. Can I export the result?
Yes. Use the CSV button for spreadsheet records. Use the PDF button for a simple printable summary of the current calculation.
