| From: | To: |
The US Army Legacy Retirement Pay system calculates retirement benefits based on years of service and the highest 36 months (High-3) of basic pay. This traditional pension plan provides a defined benefit for service members who complete 20 or more years of service.
The calculator uses the legacy retirement pay formula:
Where:
Explanation: The formula multiplies 2.5% by the total years of service and the average of the highest 36 months of basic pay to determine monthly retirement benefits.
Details: Accurate retirement pay calculation is essential for financial planning, retirement readiness, and understanding the long-term benefits of military service. It helps service members prepare for post-service life and make informed career decisions.
Tips: Enter years of service (including partial years as decimals) and the High-3 average basic pay. The High-3 is typically calculated as the average of the highest 36 months of basic pay during military service.
Q1: Who qualifies for legacy retirement pay?
A: Service members who entered service before January 1, 2018, and complete 20 or more years of qualifying service are eligible for the legacy retirement system.
Q2: What is included in High-3 average basic pay?
A: High-3 includes basic pay only - it does not include allowances, special pays, or bonuses. It's the average of the highest 36 months of basic pay.
Q3: How are partial years of service calculated?
A: Partial years are calculated as decimal fractions (e.g., 20 years 6 months = 20.5 years). Each month counts as 1/12 of a year.
Q4: Are there cost-of-living adjustments (COLA)?
A: Yes, military retirement pay typically receives annual cost-of-living adjustments based on the Consumer Price Index.
Q5: How does this differ from the Blended Retirement System?
A: The legacy system offers a higher pension percentage but no government matching contributions to the Thrift Savings Plan, unlike the Blended Retirement System.
