US Military Pay Calc is a free Android application developed by Crash Test Dummy Limited LLC. The app is designed to calculate the pay for US military members based on their pay grade, years of service, and zip code. The app also includes estimated yearly pay calculations for reservists based on the number of drills and active duty days.

One of the most useful features of the app is its ability to calculate BAH (Basic Allowance for Housing) based on zip code, pay grade, and dependent status. The app also includes BAS (Basic Allowance for Subsistence) calculations. Additionally, users can email the results to themselves for later use.

It's important to note that for reservists, BAH is calculated based on the zip code and is not "BAH RC/T," which is the type of BAH applicable for active duty periods under 30 days. The app is updated for estimated 2023 pays, making it a helpful tool for military members to accurately calculate their pay. Overall, US Military Pay Calc is a helpful and user-friendly application for US military members.
