Army Deployment Pay Calculator

Army Deployment Pay Calculator

Understanding your pay during a military deployment can be complex, with various allowances and potential tax benefits coming into play. This calculator helps U.S. Army personnel estimate their gross pay and allowances for a deployment period, providing a clearer picture of their financial compensation.

Deployment Pay Components Explained

• Base Pay: Your regular monthly salary based on your rank and years of service. While deployed, you continue to receive your base pay.
• Hostile Fire Pay / Imminent Danger Pay (HFP/IDP): A special pay of $225 per month for service members serving in designated hostile fire or imminent danger areas. This is often tax-exempt when earned in a combat zone.
• Family Separation Allowance (FSA): A monthly allowance of $250 for service members with dependents who are separated from their families due to deployment for more than 30 days.
• Hardship Duty Pay – Location (HDP-L): Paid to service members assigned to specific locations where living conditions are substantially below the standard in the continental U.S. Rates vary ($50, $100, or $150 per month) depending on the hardship level of the location.
• Combat Zone Tax Exclusion (CZTE): A significant benefit where certain pay earned while serving in a designated combat zone (or qualified hazardous duty area) is excluded from federal income tax. This includes all HFP/IDP and, for enlisted personnel, all base pay. For officers, base pay exclusion is capped at the highest enlisted pay plus HFP/IDP. This calculator focuses on gross pay, but it's crucial to remember the tax-free nature of these earnings.
