High-3 vs BRS Military Retirement — Which System Actually Pays More?

Military retirement has gotten complicated with all the misinformation flying around about which system actually puts more money in your pocket. As someone who spent 22 years in the Army — retired as a Chief Warrant Officer Three — and then another decade as a Certified Financial Planner working almost exclusively with active duty and retired service members, I learned everything there is to know about these two retirement systems. Kitchen tables in base housing. Unit dayrooms. One-on-one counseling sessions that ran two hours past when they should have ended. I have run these numbers every possible direction. What follows is not a textbook summary — it is a real comparison, built on 2026 pay table figures, broken down by rank, so you can see exactly what lands in your pocket.

Most explainers hand you the formula and call it done. That is not useful when you are deciding whether to stay in, planning your retirement date, or trying to give straight advice to a junior Soldier who just hit their four-year mark. Numbers matter. So let us get into them.

High-3 vs BRS — The Core Difference in One Number

But what is the actual gap between these two systems? In essence, it comes down to a single multiplier. But it is much more than that — because that one number follows you for the rest of your life.

Under the legacy High-3 system, you earn 2.5% of your average base pay for each year of service. The Blended Retirement System — BRS — drops that multiplier to 2.0%. At 20 years, High-3 pays out 50% of your High-3 average base pay as a monthly pension. BRS pays 40%. That is a 10 percentage-point gap that never closes. And because military retirement is a percentage of base pay rather than a fixed dollar amount, higher retirement ranks mean larger raw-dollar gaps.

Probably should have opened with this section, honestly — because once you internalize that 2.5% versus 2.0% split, everything else in this comparison clicks into place.

One important catch exists, though. BRS members receive government contributions to their Thrift Savings Plan — matching up to 5% of base pay after the first two years, with vesting beginning at year two. So BRS is not simply a reduced pension. It is a pension plus a funded investment account. Whether that trade makes sense depends entirely on your specific career path.

Real Dollar Comparison by Rank — 2026 Pay Tables

Here is where things get concrete. I pulled the 2026 military pay tables and ran three scenarios at common retirement ranks. For High-3 calculations, I used the average of the member’s highest 36 months of base pay — which, in practice, usually means the final three years before retirement.

E-7 Retiring at 20 Years

An E-7 with 20 years earns approximately $6,010 per month in base pay under the 2026 tables. Assuming they have held that pay grade for at least three years — common at this point in a career — the High-3 average comes in right around that same figure.

• High-3 pension: $6,010 × 50% = $3,005 per month
• BRS pension: $6,010 × 40% = $2,404 per month
• Monthly gap: $601 in favor of High-3
• Annual gap: $7,212 in favor of High-3

That is real money — not abstract. Over a 20-year retirement horizon, that pension gap reaches roughly $144,240 before cost-of-living adjustments. Military retirement does receive annual COLA increases, which compound that difference further over time.

O-5 Retiring at 20 Years

A Lieutenant Colonel or Commander at 20 years draws significantly more. Base pay for an O-5 with 20 years of service runs approximately $10,142 per month in 2026.

• High-3 pension: $10,142 × 50% = $5,071 per month
• BRS pension: $10,142 × 40% = $4,057 per month
• Monthly gap: $1,014 in favor of High-3
• Annual gap: $12,168 in favor of High-3

Nearly $1,000 a month. Over 25 years of retirement, that is more than $300,000. The higher the rank, the bigger the High-3 advantage — assuming, critically, that you actually hit 20 years.

E-5 Who Separates at 8 Years

This is the scenario BRS was genuinely designed to address. An E-5 who separates at 8 years under legacy High-3 walks away with zero pension. Nothing at all. Under BRS, that same Soldier leaves with a vested TSP account carrying years of government matching contributions. That is not a small thing — and for a lot of people reading this, it is the most important number on the page.

The TSP Match — Where BRS Makes Up Ground

Frustrated by watching junior enlisted members leave after six or eight years with no retirement benefit whatsoever, Congress built the TSP match directly into BRS to close that gap. Here is how it actually works.

The government automatically contributes 1% of base pay to your TSP from day one — no contribution required on your end. After 60 days of service, they match your contributions dollar-for-dollar up to 3% of base pay, then 50 cents on the dollar for the next 2%. Contribute 5% yourself, receive 5% from the government. Full match vests at two years of service.

For that E-7 earning roughly $6,010 per month — a full 5% government match equals $300.50 monthly into their TSP. Over a 20-year career, starting contributions at year two and earning a conservative 6% average annual return in something like the C Fund or an age-appropriate Lifecycle fund, that match alone grows to approximately $130,000 to $155,000 by retirement. Exact timing and contribution consistency affect the final number, but that range is realistic.

That does not fully close the $144,240 pension gap for the E-7. It gets close — uncomfortably close, honestly. At higher ranks, the TSP match amounts grow alongside base pay, but the pension gap grows too. The math is tight. There is no clean knockout winner for a full 20-year retiree under either system.

What the TSP match does — unambiguously — is create tangible value for service members who leave before 20 years. Nothing comparable exists under High-3. That is the genuine innovation BRS brought to the table.

Who Wins at 20 Years — Who Wins at 30

Let me give you the direct answer I give every client who asks this question.

If you are certain you will retire at 20 or more years: High-3 produces a higher guaranteed lifetime pension. The math does not lie — 50% beats 40% every single month until you die, and then continues for surviving spouses under the Survivor Benefit Plan. The TSP match helps, but it rarely catches up entirely, especially for mid-grade officers and senior NCOs whose pension amounts are substantial.

If there is any real chance you leave before 20 years: BRS wins, and it is not particularly close. A service member separating at year 12 with a vested TSP account containing tens of thousands in government contributions is in a materially better position than someone leaving under High-3 with a pension of exactly zero dollars.

At 30 years, the multiplier gap widens further — High-3 pays 75% of base pay, BRS pays 60%. For a senior enlisted member or field-grade officer, that spread at 30 years can exceed $2,000 per month. That is $24,000 per year. The TSP match, while compounding nicely by that point, does not generate $24,000 in annual distributions for most enlisted retirees. High-3 wins decisively at 30 years.

The honest lesson from counseling hundreds of service members — one I wish I had communicated more bluntly early in my practice — is that this decision is fundamentally a bet on your own career longevity. Most 19-year-olds who enlist are convinced they will do 20. The ones who actually make it are fewer than the services would prefer. BRS hedges that uncertainty. High-3 rewards certainty. Don’t make my mistake of assuming everyone who walks into your office already knows which category they fall into.

The BRS Opt-In Is Closed — What If You Missed It

Service members already on active duty before January 1, 2018 had a window — January 1 through December 31, 2018 — to voluntarily opt into BRS. That window is permanently shut. The decision was irrevocable. There is no going back.

Burned by confusion during that opt-in period, plenty of experienced NCOs and officers stayed in High-3 without fully understanding what they were keeping or walking away from. If that is your situation, here is what matters going forward.

Staying in High-3 means keeping the 2.5% multiplier — the good news, especially for anyone on track to hit 20 or more years. The trade-off is zero automatic government TSP contributions and zero matching. You can still contribute to TSP yourself, which you absolutely should, but every dollar in that account comes from your own pocket.

High-3 members currently serving might find the best option is treating personal TSP contributions as a self-funded version of the BRS match — that is because the math requires you to build a supplemental account alongside your eventual pension, and waiting does real damage to your long-term balance. Contribute at least 5% of base pay, lean toward Roth TSP if your income level supports it, and park it in age-appropriate funds. Not matching dollars, but not nothing either.

New accessions — anyone who joined after January 1, 2018 — are automatically enrolled in BRS with no choice in the matter. For them, the framework is simpler: understand what you have, contribute the full 5% to capture the full government match from day one, and let the TSP work as hard as possible to offset the lower pension multiplier.

This new idea of blending pension and investment accounts took off several years after its 2018 rollout and eventually evolved into the standard military retirement framework enthusiasts know and debate today. The systems are different — neither is objectively better for every person. But the numbers, run against 2026 pay tables and realistic career scenarios, tell a clear enough story. That story depends almost entirely on how long you actually plan to serve.
