Understanding the Army High-3 Retirement System

The High-3 retirement system is one of the primary methods for calculating retirement pay for U.S. military members, including those serving in the Army. This system applies to service members who entered the military on or after September 8, 1980, and before January 1, 2018. For those who joined on or after January 1, 2018, the Blended Retirement System (BRS) is the default.

How the High-3 System Works

Under the High-3 system, a retiree's annuity (retirement pay) is calculated based on the average of their highest 36 months (3 years) of basic pay. This average is then multiplied by a factor of 2.5% for each year of creditable service. The formula is straightforward:

Monthly Retirement Pay = (Average of Highest 36 Months of Basic Pay) × (Years of Creditable Service × 0.025)

Let's break down the key components:

• Years of Creditable Service: This refers to the total number of years a service member has served that count towards retirement. Typically, a minimum of 20 years of active duty service is required to qualify for retirement pay. Each additional year beyond 20 increases the multiplier.
• Highest 36 Months Average Basic Pay: This is the most critical factor. It's the average of the highest 36 consecutive months of basic pay earned during a service member's career. For most, this will be their last three years of service, as basic pay generally increases with rank and time in service. It's important to note that this only includes basic pay, not allowances like BAH (Basic Allowance for Housing) or BAS (Basic Allowance for Subsistence).
• Multiplier (2.5% per year): For every year of creditable service, the service member earns 2.5% of their high-3 average basic pay. So, 20 years of service would result in 50% (20 * 2.5%) of the high-3 average, 25 years would be 62.5%, and 30 years would be 75%.

Who is Eligible for High-3?

The High-3 system primarily applies to service members who entered the military between September 8, 1980, and December 31, 2017. Those who joined before September 8, 1980, fall under the "Final Pay" system, which uses the basic pay at the time of retirement. Those who joined on or after January 1, 2018, are typically under the Blended Retirement System (BRS), which combines a smaller defined benefit (High-2.5) with a Thrift Savings Plan (TSP) contribution.

Cost of Living Adjustments (COLA)

Once a service member retires, their High-3 retirement pay is subject to annual Cost of Living Adjustments (COLAs). These adjustments are typically tied to the Consumer Price Index (CPI) and are designed to help maintain the purchasing power of retirement benefits over time. This means that while your initial retirement pay is calculated based on the High-3 formula, its value will generally increase each year.

Using the Calculator

Our Army High-3 Retirement Calculator helps you estimate your potential monthly and annual retirement pay. Simply input:

1. Years of Creditable Service: Enter the total number of years you expect to serve that count towards retirement.
2. Highest 36 Months Average Basic Pay ($): Provide the average monthly basic pay you anticipate earning during your highest-paid 36 consecutive months. This is often your basic pay just before retirement.

The calculator will then instantly provide your estimated monthly and annual retirement pay based on the High-3 formula. This tool is invaluable for retirement planning and understanding your future financial outlook as an Army retiree.

Example Calculation:

Let's consider an example:

• Years of Creditable Service: 22 years
• Highest 36 Months Average Basic Pay: $5,500 per month

Using the formula:

Monthly Retirement Pay = $5,500 × (22 × 0.025)
Monthly Retirement Pay = $5,500 × 0.55
Monthly Retirement Pay = $3,025.00

Annual Retirement Pay = $3,025.00 × 12
Annual Retirement Pay = $36,300.00

This example demonstrates how the calculator processes your inputs to provide a clear estimate of your retirement benefits under the High-3 system.
