The U.S. Army Old Retirement Plan: A Comprehensive Guide for Service Members

As a finance and investment expert, I often analyze retirement plans to help individuals make informed decisions. The U.S. Army’s old retirement plan, officially known as the High-3 Retirement System, was the standard before the Blended Retirement System (BRS) took effect in 2018. Many service members who enlisted before 2018 still fall under this plan, and understanding its mechanics is crucial for long-term financial planning.

How the Army Old Retirement Plan Works

The High-3 system calculates retirement pay based on three key factors:

  1. Years of Service – The total number of years served in the military.
  2. Rank at Retirement – The pay grade at the time of retirement.
  3. Average of Highest 36 Months of Basic Pay – The “High-3” refers to the average of the highest 36 months of basic pay, typically the last three years of service.

The formula for calculating retirement pay under the High-3 system is:

Retirement\ Pay = (Years\ of\ Service \times 2.5\%) \times Average\ of\ Highest\ 36\ Months\ of\ Basic\ Pay

For example, a Sergeant Major (E-9) retiring after 20 years with an average High-3 pay of $6,000/month would receive:

Retirement\ Pay = (20 \times 0.025) \times \$6,000 = 0.50 \times \$6,000 = \$3,000/month

Key Features of the High-3 Plan

  • Immediate Annuity – Unlike civilian 401(k) plans, the High-3 system provides a guaranteed monthly pension immediately upon retirement.
  • Cost-of-Living Adjustments (COLA) – Retirement pay increases annually based on inflation.
  • Survivor Benefit Plan (SBP) – Optional coverage that provides a portion of retirement pay to a surviving spouse.

Comparison: High-3 vs. Blended Retirement System (BRS)

The Blended Retirement System (BRS), introduced in 2018, combines a reduced pension with a Thrift Savings Plan (TSP) and government matching. Here’s a comparison:

FeatureHigh-3 Retirement PlanBlended Retirement System (BRS)
Pension Multiplier2.5% per year of service2.0% per year of service
TSP MatchingNo automatic matchingUp to 5% government match
Lump-Sum BuyoutNot availableOptional mid-career lump sum
EligibilityPre-2018 enlisteesPost-2018 enlistees (opt-in available for some)

Which One is Better?

The answer depends on individual circumstances:

  • High-3 is better for those who serve 20+ years due to the higher pension.
  • BRS is better for those who may not complete 20 years due to TSP benefits.

Calculating Retirement Pay: A Deeper Look

Let’s break down the High-3 calculation further. Assume a Lieutenant Colonel (O-5) retires after 24 years with a High-3 average of $8,500/month.

Retirement\ Pay = (24 \times 0.025) \times \$8,500 = 0.60 \times \$8,500 = \$5,100/month

If the same officer served 30 years, the calculation would be:

Retirement\ Pay = (30 \times 0.025) \times \$8,500 = 0.75 \times \$8,500 = \$6,375/month

Early Retirement (Reserve/Guard Considerations)

Reserve and National Guard members can retire earlier but with reduced benefits until age 60 (or earlier if deployed). The formula adjusts as:

Reduced\ Retirement\ Pay = (Years\ of\ Service \times 2.5\%) \times High-3\ Average \times (1 - Early\ Retirement\ Penalty)

Tax Implications of Military Retirement Pay

Military retirement pay is federally taxable but may be state-tax-free depending on residency. For example:

  • Texas, Florida, and Nevada do not tax military pensions.
  • California and Virginia tax military retirement income.

Example: Tax Impact on a $3,000 Monthly Pension

If a retiree lives in California (9.3% state tax), they would pay:

Annual\ State\ Tax = \$3,000 \times 12 \times 0.093 = \$3,348/year

In contrast, a retiree in Texas pays $0 in state taxes on the same pension.

Survivor Benefits and Life Insurance

The Survivor Benefit Plan (SBP) allows retirees to allocate a portion of their pension to a surviving spouse. The cost is 6.5% of the chosen base amount.

For a retiree with $3,000/month pension electing full coverage:

SBP\ Cost = \$3,000 \times 0.065 = \$195/month

The surviving spouse would then receive 55% of the pension:

Survivor\ Benefit = \$3,000 \times 0.55 = \$1,650/month

Investment Strategies to Supplement Military Retirement

While the High-3 pension is stable, inflation can erode purchasing power over time. I recommend:

  1. Maximizing TSP Contributions – Even under High-3, TSP offers tax-deferred growth.
  2. Roth IRA Conversions – Tax-free withdrawals in retirement.
  3. Real Estate Investments – Passive income through rental properties.

Example: TSP Growth Over 20 Years

Assume a service member contributes $500/month to TSP with a 7% annual return:

Future\ Value = \$500 \times \frac{(1 + 0.07)^{240} - 1}{0.07} \approx \$260,000

Combined with a $3,000/month pension, this creates a robust retirement.

Final Thoughts

The Army’s old retirement plan remains one of the most secure pension systems available. However, smart financial planning—such as tax optimization, SBP decisions, and supplemental investments—can enhance long-term stability. If you’re under the High-3 system, maximize its benefits while diversifying with other retirement vehicles.
