High-3 vs Blended Retirement System (BRS): Which Military Retirement Plan Is Better in 2026?

Two Retirement Systems, One Critical Decision

If you're serving in the US military in 2026, your retirement plan depends on when you entered service — and the difference between the High-3 Legacy Retirement System and the Blended Retirement System (BRS) can mean tens of thousands of dollars over your lifetime. Understanding how each system works, how your pension is calculated, and when each one "breaks even" is essential for every service member who plans to make a career out of the military — or even serve a single enlistment.

This guide breaks down both retirement systems side by side, walks through real dollar calculations for common ranks, and helps you understand which plan works best for your situation. Whether you're a new enlistee trying to decide whether to opt into BRS or a mid-career member evaluating your options, this is the definitive resource for military retirement planning in 2026.

What Is the High-3 Legacy Retirement System?

The High-3 Retirement System (also called "High-36" or simply "Legacy") is the traditional military pension plan that existed for decades before 2018. Under High-3, career members who serve 20 or more years receive a lifetime pension calculated as follows:

• Multiplier: 2.5% per year of creditable service
• Base: Average of your highest 36 consecutive months of basic pay
• Formula: 2.5% × years of service × High-3 average base pay

For example, an E-7 who retires after exactly 20 years with a High-3 average basic pay of $5,800/month would receive:

Annual pension = 2.5% × 20 × ($5,800 × 12) = $34,800/year ($2,900/month)

That pension is paid for life, with annual Cost of Living Adjustments (COLA) to keep pace with inflation. There is no TSP matching under the High-3 system — the government does not contribute to your Thrift Savings Plan. Your retirement income comes entirely from the pension.

What Is the Blended Retirement System (BRS)?

The Blended Retirement System (BRS) went into effect on January 1, 2018, as part of the 2016 National Defense Authorization Act. It was designed to provide retirement benefits to the roughly 85% of service members who serve fewer than 20 years and would otherwise leave with no pension at all.

Under BRS, career members who serve 20+ years still receive a pension, but with a reduced multiplier:

• Multiplier: 2.0% per year of creditable service (reduced from 2.5%)
• Base: Average of your highest 36 consecutive months of basic pay (same as High-3)
• Formula: 2.0% × years of service × High-3 average base pay
• TSP Matching: Government matches your contributions up to 5% of basic pay (dollar-for-dollar on the first 3%, then 50% on the next 2%)
• Continuation Pay: A one-time bonus at the 12-year mark for members who commit to serve an additional 4 years (typically 2.5–13 months of basic pay depending on rank and specialty)
• Mid-Career Retraining: Members who entered before 2018 could choose to opt in to BRS during 2018

Using the same E-7 example — 20 years of service, $5,800/month High-3 average — the BRS pension would be:

Annual pension = 2.0% × 20 × ($5,800 × 12) = $27,840/year ($2,320/month)

That's $580/month less than the High-3 pension. But the BRS member also has TSP savings and government matching that the High-3 member does not.

The Break-Even Analysis: When Does BRS Catch Up?

The most common question service members ask is: "At what point does the BRS — with its lower pension but TSP matching — equal what I would have received under High-3?"

The answer depends on several factors: your rank at retirement, how much you contribute to TSP, your investment returns, and how long you live after retirement. But we can model a realistic scenario.

Break-Even Scenario: E-7 Retiring at 20 Years

Assume our E-7 contributes 5% of basic pay to TSP throughout their career, and the government matches with the full 5%. With an average basic pay of approximately $4,800/month over the career (accounting for raises and promotions), the annual TSP contributions would be:

• Member contribution: 5% × $4,800 × 12 = $2,880/year
• Government match: 5% × $4,800 × 12 = $2,880/year
• Total annual TSP contribution: $5,760/year

Over 20 years, with a conservative average annual return of 7%, the TSP balance at retirement would be approximately $260,000–$290,000.

Using the standard 4% withdrawal rule, that TSP balance generates about $870–$970/month in retirement income. Combined with the BRS pension of $2,320/month, total retirement income is approximately $3,190–$3,290/month — which actually exceeds the High-3 pension of $2,900/month.

The break-even point: Under these assumptions, BRS surpasses High-3 at approximately age 58–62 (roughly 18–22 years after retirement). If you live past that age, BRS provides more total lifetime income. If you die before that point, High-3 provides more total value.

However, this analysis doesn't account for the Continuation Pay bonus (which adds $15,000–$60,000+ to TSP) or the lump-sum pension option available under BRS, both of which can significantly shift the break-even point earlier.

What About Members Who Serve Fewer Than 20 Years?

Here's where BRS truly shines. Under the High-3 system, if you serve fewer than 20 years, you walk away with zero pension. Nothing. Your retirement benefit is whatever you personally saved in TSP — with no government matching.

Under BRS, any member who serves at least 2 years becomes vested in TSP matching. That means even if you serve just one 4-year enlistment and leave, you keep:

• All your personal TSP contributions
• All government matching contributions (after 2 years of service)
• All investment growth on those contributions

For a junior enlisted member (E-3) who serves 4 years and contributes 5% of basic pay, the TSP balance at separation would be approximately $8,000–$12,000 — including government matching. Under High-3, that same member would have only their personal contributions (roughly $5,000–$7,000) with no match.

Given that approximately 85% of service members do not complete a full 20-year career, BRS provides retirement benefits to the vast majority of veterans who would otherwise receive nothing from the legacy system.

Continuation Pay: The Hidden BRS Bonus

One of the most underappreciated features of BRS is Continuation Pay — a one-time bonus paid to members who have completed approximately 12 years of service and agree to serve an additional 4 years.

Continuation Pay rates vary by rank and service branch, but the 2026 rates are approximately:

• Enlisted (E-5 to E-9): 2.5–6 months of basic pay
• Warrant Officers (W-1 to W-5): 2.5–6 months of basic pay
• Officers (O-3 to O-6): 6–13 months of basic pay

For an E-7 at the 12-year mark, Continuation Pay is approximately $20,000–$35,000 (before taxes). If rolled directly into TSP, this single bonus — with 8+ years of investment growth — can add $40,000–$70,000 to your retirement balance by the time you retire at 20 years.

There is no equivalent benefit under the High-3 system.

The Lump-Sum Pension Option Under BRS

Another unique feature of BRS is the ability to elect a lump-sum payment at retirement in exchange for a reduced monthly pension. You can choose to receive either 25% or 50% of the discounted present value of your future pension payments as an upfront cash payment.

Your monthly pension is then reduced to either 75% or 50% of the full amount until you reach age 83 (the Social Security "breakeven" age), at which point it reverts to the full amount.

This option is valuable for members who want to:

• Pay off a mortgage or other debt at retirement
• Make a large investment or business startup
• Cover transition costs to civilian life
• Fund a child's education

The lump-sum amount for an E-7 retiring at 20 years is approximately $80,000–$120,000 for the 25% option, or $160,000–$240,000 for the 50% option (discounted present value).

Which System Is Better for You?

The answer depends on your career plans, financial discipline, and risk tolerance:

High-3 Is Better If:

• You entered service before January 1, 2018, and chose to stay in the legacy system
• You are confident you will complete a full 20+ year career
• You prefer a guaranteed higher monthly pension with no investment risk
• You do not want to actively manage TSP investments
• You expect to live well past age 75–80 (maximizing the higher monthly pension)

BRS Is Better If:

• You entered service on or after January 1, 2018 (you're automatically enrolled)
• You are unsure whether you'll complete 20 years
• You are comfortable managing TSP investments and want control over your retirement savings
• You value portability — your TSP balance goes with you even if you leave before 20 years
• You want the flexibility of Continuation Pay and the lump-sum pension option

For the vast majority of today's active-duty service members, BRS is the only option — and it's a genuinely better system for most people, especially those who may not complete a full career.

Maximizing Your Retirement Under Either System

Regardless of which retirement system you're under, these strategies will maximize your military retirement income:

1. Contribute at least 5% to TSP. Under BRS, this maximizes your government match — that's free money. Under High-3, TSP is still a powerful tax-advantaged savings vehicle even without matching.
2. Choose aggressive TSP funds early, then shift conservative. When you're young, the C Fund (S&P 500 index) and S Fund (small-cap index) historically outperform. As you approach retirement, gradually shift to the G Fund (government securities) to protect your gains.
3. Never take early TSP withdrawals. Withdrawals before age 59½ incur a 10% penalty plus income taxes. Let your money compound.
4. Time your retirement to maximize High-3. If possible, retire after a pay raise or promotion so your highest 36 months reflect your peak earnings. Even one year at a higher rank can add hundreds of dollars per month to your lifetime pension.
5. Elect Continuation Pay at 12 years. Under BRS, this is essentially free money. Roll it directly into TSP for maximum growth.
6. Consider the Survivor Benefit Plan (SBP). SBP provides your surviving spouse with up to 55% of your retired pay. The premium is modest (6.5% of base retired pay) and can be critical for your family's financial security.

Frequently Asked Questions: High-3 vs BRS

Can I switch from High-3 to BRS?

If you entered service before January 1, 2018, you had a one-time opportunity to opt in to BRS during 2018. That window has closed. If you didn't opt in, you remain under the High-3 legacy system for your entire career.

How is my High-3 average calculated?

Your High-3 average is the mean basic pay from your highest 36 consecutive months of service. For most members retiring at 20 years, this is their last 36 months. However, if you received a significant promotion or pay raise earlier, it could be a different 36-month window. Basic pay only — BAH, BAS, and special pays are not included.

What happens to my TSP if I don't serve 20 years?

Under BRS, you keep all personal contributions and all government matching contributions (once vested at 2 years), plus all investment growth. You can roll the balance into an IRA or your next employer's 401(k). Under High-3, you keep your personal contributions and growth, but there is no government match to keep.

Does BRS or High-3 affect my VA disability compensation?

No. VA disability compensation is separate from your military retirement pension. However, under the Concurrent Retirement and Disability Pay (CRDP) program, eligible retirees can receive both full military retired pay and VA disability compensation. The rules differ slightly between High-3 and BRS regarding concurrent receipt — consult a Veterans Service Organization (VSO) for your specific situation.

What is the REDUX retirement plan?

REDUX was a third retirement option available to members who entered service between August 1, 1986, and December 31, 2017. It offered a $30,000 Career Status Bonus at 15 years in exchange for a reduced pension multiplier (2.0% instead of 2.5%). REDUX was eliminated for new entrants after 2017. If you're under BRS, REDUX does not apply to you.
