Blended Retirement System (BRS) vs High-3: Military Retirement Calculator 2026

Blended Retirement System vs High-3: Which Military Retirement Plan Pays More?

If you are trying to decide between the Blended Retirement System (BRS) and the legacy High-3 retirement plan, you are asking one of the most important financial questions of your military career. The difference between these two systems can amount to hundreds of thousands of dollars over a 20-year career — and the right answer depends entirely on your personal situation, your ability to save, and how long you plan to serve.

The Blended Retirement System was introduced in 2018 as the default for all new service members. It combines a smaller defined-benefit pension with government matching contributions to your Thrift Savings Plan (TSP) and a mid-career continuation pay bonus. The High-3 system, which remains in effect for those who opted out of BRS, offers a larger pension but no TSP matching and no continuation pay.

This guide walks through both systems in detail, shows you exactly how to calculate your retirement pay under each one, and helps you determine which plan maximizes your total compensation. Whether you are an E-4 with four years of service trying to decide whether to opt in, or an O-5 planning your retirement timeline, this is the definitive breakdown.

How the High-3 Retirement System Works

The High-3 retirement system is the traditional military pension that has been in place for decades. It is a defined-benefit plan, meaning your retirement pay is guaranteed based on a formula — not on how well your investments perform.

The High-3 Formula

Your annual High-3 retirement pay is calculated as:

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

For example, an E-7 who retires after 20 years of service with an average basic pay of $5,500 per month:

• Average monthly basic pay: $5,500
• Multiplier: 2.5% × 20 years = 50%
• Monthly retirement pay: $5,500 × 50% = $2,750/month
• Annual retirement pay: $2,750 × 12 = $33,000/year

At 26 years of service, that same E-7 would receive:

• Multiplier: 2.5% × 26 = 65%
• Monthly retirement pay: $5,500 × 65% = $3,575/month
• Annual retirement pay: $3,575 × 12 = $42,900/year

The maximum multiplier under High-3 is 75% (reached at 30 years of service), though most members retire at 20 years with a 50% multiplier.

High-3: What You Do NOT Get

Under the High-3 system, you receive no government contributions to your Thrift Savings Plan. If you contribute to TSP, it is entirely your own money — the government adds nothing. You also do not receive the mid-career continuation pay bonus that BRS members get.

This is the critical trade-off: High-3 gives you a larger guaranteed pension, but zero help building your TSP balance. For service members who do not contribute to TSP on their own, High-3 is often the better deal because the pension is significantly larger.

How the Blended Retirement System (BRS) Works

The Blended Retirement System was designed to provide retirement benefits to the 85% of service members who leave before reaching 20 years of qualifying service. Under High-3, those who separate before 20 years receive nothing — no pension, no retirement benefit at all. BRS changes that equation.

The BRS Pension Formula

BRS uses the same basic formula as High-3, but with a smaller multiplier:

BRS Retirement Pay = (Average of Highest 36 Months of Basic Pay) × (2.0% × Years of Service)

Notice the difference: 2.0% per year instead of 2.5%. For a 20-year retiree, that means a 40% multiplier instead of 50% — a 20% reduction in monthly pension.

Using the same E-7 example from above:

• Average monthly basic pay: $5,500
• BRS multiplier: 2.0% × 20 years = 40%
• BRS monthly retirement pay: $5,500 × 40% = $2,200/month
• Annual retirement pay: $2,200 × 12 = $26,400/year

Compared to High-3, this E-7 receives $550 less per month — or $6,600 less per year — in pension payments. Over a 20-year retirement, that is a difference of $132,000 in pension income alone.

BRS TSP Matching: The Government Contribution

Here is where BRS makes up ground. Under BRS, the government automatically contributes 1% of your basic pay to your TSP, even if you contribute nothing. Then it matches your contributions dollar-for-dollar up to 3% and $0.50 on the dollar from 3% to 5%.

Your Contribution	Government Match	Total Monthly TSP Addition
0%	1% automatic	1% of basic pay
1%	1% automatic + 1% match	2% of basic pay
3%	1% automatic + 3% match	4% of basic pay
5%	1% automatic + 4% match	5% of basic pay
7%	1% automatic + 4% match	5% of basic pay (your 2% extra goes in, no match)

For an E-7 earning $5,500/month in basic pay who contributes 5%:

• Your contribution: $275/month
• Government match: $220/month (1% automatic + 4% match)
• Total monthly TSP addition: $495/month
• Annual TSP addition: $5,940/year

Over a 20-year career, that government match alone totals $118,800 in contributions — and that is before any investment growth. With average 7% annual returns, the government-matched portion could grow to over $250,000 by the time you retire.

BRS Continuation Pay: The Mid-Career Bonus

The third component of BRS is Continuation Pay — a mid-career bonus paid to members who agree to serve an additional 3-4 years. This bonus is designed to encourage retention and partially offset the reduced pension multiplier.

Continuation pay rates vary by branch and rank, but typical amounts are:

• Enlisted members: 2.5 to 13 months of basic pay
• Officers: 2.5 to 6 months of basic pay
• Reserve members: 2.5 to 6 months of basic pay (prorated)

For an E-7 at the 12-year mark, continuation pay might be 6 months of basic pay — approximately $33,000 in a single lump sum. This money can be deposited directly into your TSP, where it continues to grow tax-deferred.

BRS vs High-3: Side-by-Side Comparison

Here is how the two systems compare across the key dimensions that matter for your retirement planning:

Feature	High-3	Blended Retirement System (BRS)
Pension multiplier	2.5% per year	2.0% per year
20-year pension (E-7 example)	$2,750/month	$2,200/month
TSP matching	None	Up to 5% match + 1% automatic
Continuation pay	None	2.5-13 months basic pay
Pre-20-year benefit	Nothing	TSP balance with matching
Defined benefit	Yes (larger)	Yes (smaller)
Defined contribution	No	Yes (TSP matching)
Lump sum option	No	Yes (up to 25% of pension)

When High-3 Wins: The Pension Advantage

High-3 is the better choice when you are confident you will serve 20 or more years and you are not contributing to TSP. The math is straightforward: a 25% larger pension (2.5% vs 2.0% per year) compounds over decades of retirement.

High-3 Advantage Over a 25-Year Retirement

For an E-7 retiring at 20 years with a $5,500 average basic pay:

• High-3 monthly pension: $2,750
• BRS monthly pension: $2,200
• Monthly difference: $550
• Annual difference: $6,600
• 25-year retirement difference: $165,000

That $165,000 gap is what BRS needs to overcome through TSP matching and continuation pay. For a member who contributes 5% to TSP and receives the maximum continuation pay, the BRS TSP balance at retirement would need to generate approximately $550/month in withdrawals to break even — which requires a TSP balance of roughly $110,000 at a 6% withdrawal rate.

With 20 years of maximum matching at 7% returns, the BRS TSP balance would be approximately $250,000 — more than enough to close the gap. But this requires consistent 5% contributions for the entire career, which many service members do not do.

When BRS Wins: The TSP Matching Advantage

BRS is the better choice when you consistently contribute at least 5% to TSP, when you might separate before 20 years, or when you value the flexibility of a portable retirement benefit.

Scenario 1: You Separate Before 20 Years

This is the clearest BRS win. If you serve 8 years and then separate:

• High-3: $0 pension (you did not reach 20 years)
• BRS: $0 pension, but you keep your TSP balance with all government matching contributions

With 8 years of 5% contributions and full matching on a $3,500/month basic pay (E-5 average), your TSP balance could be $40,000-$60,000 including investment growth. Under High-3, you would walk away with nothing.

Scenario 2: You Contribute 5% to TSP for 20 Years

For a disciplined saver who contributes 5% throughout their career, BRS often comes out ahead even at the 20-year mark. The combination of TSP matching, continuation pay, and investment growth can exceed the High-3 pension advantage.

For an O-4 retiring at 20 years with $7,000 average basic pay:

• High-3 pension: $7,000 × 50% = $3,500/month
• BRS pension: $7,000 × 40% = $2,800/month
• Pension gap: $700/month
• BRS TSP balance (est.): $350,000+
• TSP monthly withdrawal (4% rule): $1,167/month
• BRS total monthly income: $2,800 + $1,167 = $3,967/month

In this scenario, BRS produces $467 more per month in total retirement income — and the TSP balance is portable, inheritable, and not subject to the same political risk as pension formulas.

Scenario 3: You Do Not Contribute to TSP

If you do not contribute anything to TSP, BRS is almost always worse. You still get the 1% automatic contribution, but that alone cannot overcome the 20% pension reduction. For a non-saver, High-3 is the clear winner at 20+ years of service.

How to Calculate Your Military Retirement Pay

Whether you are under BRS or High-3, calculating your estimated retirement pay requires three pieces of information:

1. Your average basic pay over your highest 36 months — This is typically your base pay during your final three years of service.
2. Your total years of qualifying service — Each year counts as one year; partial years are prorated by month.
3. Your retirement multiplier — 2.5% per year for High-3, 2.0% per year for BRS.

Step-by-Step Calculation Example

Let us calculate retirement pay for an O-5 with 22 years of service under both systems:

Step 1: Determine average highest-36-month basic pay. For an O-5 at 22 years, the 2026 basic pay is approximately $8,900/month.

Step 2: Calculate the multiplier.

• High-3: 22 × 2.5% = 55%
• BRS: 22 × 2.0% = 44%

Step 3: Multiply average pay by the multiplier.

• High-3: $8,900 × 55% = $4,895/month
• BRS: $8,900 × 44% = $3,916/month

Step 4: Add TSP withdrawals (if applicable). With a $300,000 TSP balance and a 4% annual withdrawal rate:

• BRS total: $3,916 + $1,000 = $4,916/month

In this scenario, BRS slightly edges out High-3 — but only because of the TSP balance. Without TSP savings, High-3 wins by $979/month.

The Lump Sum Option Under BRS

One unique feature of BRS is the lump sum option, which allows retirees to take a portion of their pension as an upfront cash payment in exchange for reduced monthly payments until age 67. You can elect to receive either 25% or 50% of the discounted present value of your retirement pay as a lump sum.

The lump sum is calculated using Treasury discount rates, which means the upfront payment is less than the total value of the monthly payments you are giving up. However, for service members who want to pay off debt, invest in a business, or purchase a home immediately after retirement, the lump sum provides flexibility that High-3 does not offer.

Important: If you elect the lump sum, your monthly retirement pay is reduced until age 67, at which point it reverts to the full amount. This creates a gap in income during your late 50s and early 60s that you need to plan for.

BRS vs High-3 by Rank: Who Benefits Most?

The value of BRS relative to High-3 varies significantly by rank and years of service. Here is a general framework:

Enlisted Members (E-1 through E-9)

Enlisted members who serve 20+ years and contribute to TSP generally benefit from BRS. The continuation pay bonus (which can be 6-13 months of basic pay for senior enlisted) is particularly valuable. However, enlisted members who do not save in TSP are better off under High-3.

Junior Officers (O-1 through O-3)

Junior officers who may separate before 20 years benefit significantly from BRS because of the TSP matching. The portable retirement benefit is valuable for officers transitioning to civilian careers. Those who commit to 20+ years and do not save are better under High-3.

Senior Officers (O-4 through O-6)

Senior officers with higher basic pay see a larger absolute pension gap between BRS and High-3. For an O-6 at 20 years, the monthly pension difference can exceed $1,000. These officers need substantial TSP balances ($250,000+) to make BRS competitive. Those who max out TSP contributions throughout their careers can still come out ahead under BRS.

Warrant Officers

Warrant officers follow the same BRS vs High-3 framework as commissioned officers. Because warrant officers often enter service later in life, the TSP matching has less time to compound, which slightly favors High-3 for those who serve 20+ years.

Making Your Decision: A Practical Framework

If you are still under the opt-in window (pre-2018 enlistees who have not yet decided), or if you are advising someone who is, here is a practical decision framework:

Choose High-3 If:

• You are confident you will serve 20+ years
• You do not currently contribute to TSP and are unlikely to start
• You prefer a guaranteed, larger monthly pension
• You are risk-averse and do not want to depend on market returns
• You are a senior officer or senior enlisted with high basic pay

Choose BRS If:

• You are not certain you will serve 20 years
• You consistently contribute at least 5% to TSP
• You value portability and want a retirement benefit that follows you if you separate
• You want the continuation pay bonus at mid-career
• You are comfortable with investment risk and want control over your retirement savings
• You are a junior enlisted member or junior officer with lower basic pay

Maximizing Your Retirement Under Either System

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

1. Contribute at Least 5% to TSP

Under BRS, this captures the full government match — an immediate 100% return on your first 3% and a 50% return on the next 2%. Under High-3, TSP contributions still grow tax-deferred and provide a supplemental retirement income stream. There is no scenario where contributing to TSP hurts you.

2. Choose the Right TSP Funds

The default G Fund (government securities) returns approximately 2-3% annually — barely keeping pace with inflation. For long-term growth, consider the C Fund (S&P 500 index), S Fund (small-cap stocks), or a Lifecycle fund matched to your retirement date. Over a 20-year career, the difference between the G Fund and C Fund can be $100,000+ in your final balance.

3. Avoid Early TSP Withdrawals

Withdrawing from TSP before age 59.5 triggers a 10% penalty plus income taxes. More importantly, you lose all future compound growth on that money. A $20,000 withdrawal at age 35 could have grown to $80,000+ by age 60 at 7% returns.

4. Understand the SBP Decision

The Survivor Benefit Plan (SBP) provides ongoing income to your surviving spouse after your death. Under both BRS and High-3, SBP costs 6.5% of your retired pay (up to a maximum of 35% of your base amount). This is an important insurance decision that affects your monthly retirement income.

5. Factor in VA Disability

Many military retirees also receive VA disability compensation. Under concurrent receipt rules, some retirees can receive both full military retirement pay and full VA disability pay. This can significantly increase your total retirement income beyond what either BRS or High-3 alone provides.
