Your planning estimate

Complete all fields to calculate your estimate.

This calculation uses your inputs. It does not determine entitlement, calculate tax liability, or replace an official award or travel authorization.

How it works

Monthly remaining allowance equals monthly BAH minus rent and utilities. Annual allowance is monthly BAH multiplied by 12. The official lookup determines your rate from duty station, grade, and dependency status; rate protection may apply.

Use amounts for the same period and enter zero for items that do not apply. Negative results represent a shortfall. Your inputs remain in your browser and are cleared when the page is reloaded.

Frequently asked questions

Are rates looked up automatically?

This tool currently uses your verified inputs. Automated rate tables require the official source files; no replacement rates are invented.

Is the result an official entitlement?

No. Your finance or transportation office determines entitlement and the actual amount paid.

Are my inputs stored?

No. Calculations run in your browser without an account or database.
