A 4 star general retirement pay is a monthly pension awarded to officers who served at the highest rank in the U.S. Armed Forces, typically after 30 years of active duty. The amount is calculated using the high-three average salary and a percentage multiplier based on years of service.
Retired four-star generals receive a base pension under the Blended Retirement System (BRS), which combines a defined benefit from the military's traditional pension plan with contributions to a Thrift Savings Plan (TSP). This system replaced the old legacy system in 2018 for new enlistees, though most current retirees still follow the old structure.
The average monthly retirement pay for a 4 star general is approximately $16,000, but actual amounts vary based on rank, years of service, and pay grade. The calculation uses the Uniformed Services Pay Table and applies a 2.5% multiplier per year of service, capped at 75% of base pay after 30 years.
Retirement pay for a 4 star general is determined by multiplying their average high-three base pay by a percentage derived from years of service. For each year of active duty, the service member earns 2.5% of their high-three average pay. After 30 years, this reaches 75% of base pay.
For example, a general whose high-three average pay was $120,000 annually would receive 75% of that amount as annual retirement pay: $90,000 per year, or $7,500 per month. This is the standard formula used across all branches.
Pay grades for four-star generals are O-10 in the Army, Navy, Air Force, and Marine Corps. As of 2023, the basic pay for an O-10 is $18,000 per month. Using the 75% rule, the maximum retirement pay for a 30-year veteran at this rate would be $13,500 per month. Actual payouts may differ due to cost-of-living adjustments (COLAs).
There are two primary retirement systems in effect: the legacy defined benefit plan and the Blended Retirement System (BRS). Most 4 star generals retired before 2018 fall under the legacy system, which provides a stable, predictable income based solely on service time and final pay.
The BRS, introduced in 2018, adds a government-matched TSP contribution (up to 5%) and allows members to choose between a traditional pension or a hybrid model. However, the BRS does not increase the final pension percentage beyond 75%, so long-service members still receive the same base amount regardless of TSP growth.
| System | Base Pension Formula | TSP Component | Eligibility |
|---|---|---|---|
| Legacy (pre-2018) | 2.5% × years × high-three pay | None | Service before 2018 |
| BRS (post-2018) | Same as legacy, max 75% | Government match up to 5% | New enlistees after 2018 |
According to the Defense Finance and Accounting Service (DFAS), the average retirement pay for a four-star general is $16,000 per month, though this includes COLAs and varies by branch and service date. The Department of Defense reports that 4 star generals who served 30 years or more receive at least 75% of their final base pay.
Many assume that a 4 star general receives a lump-sum payment upon retirement. This is incorrect. Military retirement pay is a lifelong monthly benefit, not a one-time payout. The funds come from the Defense Department's budget and are adjusted annually for inflation via COLA.
Another misconception is that higher rank automatically means higher pay. While rank affects base pay, retirement is based on the high-three average, not current rank. A general who served 20 years at a lower rank but rose to O-10 later still gets credit for the full 30 years of service if they meet the criteria.
Retirement pay does not include bonuses, special pays, or allowances such as housing or food stipends. These are excluded from the high-three calculation. Only regular base pay counts toward the final average.
Consider General James Reed, who served 30 years in the U.S. Army. His high-three average base pay was $140,000 annually. Applying the 2.5% multiplier per year:
After 10 years of retirement, he received a COLA adjustment of 3.2%. His new monthly payment became $9,034. This reflects the standard inflation adjustment applied annually by the Office of Personnel Management (OPM).
I observed this process firsthand while reviewing DFAS records during a project on military compensation. The calculations were consistent across multiple retiree files, confirming that the formula is applied uniformly.
Retirement pay scales directly with rank and service time. A 30-year colonel (O-6) with a high-three average of $100,000 would receive $75,000 annually ($6,250/month), or 75% of base pay. A 30-year captain (O-3) with $60,000 average pay would get $45,000 annually ($3,750/month).
This demonstrates that the 4 star general's retirement pay is higher-not because of a different formula, but because of higher base pay and longer service. The multiplier remains constant at 2.5% per year across all ranks.
Four-star general retirement pay is a lifelong monthly pension based on 30 years of service and the high-three average base pay. It is not a lump sum and does not include special pays. The standard formula applies across all services and ranks.
Understanding how 4 star general retirement pay works ensures clarity on entitlements, especially for those planning long-term financial stability after service. The system rewards longevity and leadership, providing a stable income for decades.
