The Military Blended Retirement System (BRS) vs High-3 Comparison Calculator helps service members who entered the military after January 1, 2018 understand the BRS, and helps those who were grandfathered in the legacy High-3 system (or given the 2018 opt-in choice) compare the two retirement systems to make an informed decision. The legacy High-3 system provides a defined benefit pension equal to 2.5% of average basic pay over the highest 3 earning years times years of service — so a 20-year retirement pays 50% of High-3 pay, with no government contribution to the Thrift Savings Plan (TSP). The Blended Retirement System, mandatory for those entering service after January 1, 2018, reduces the defined benefit multiplier to 2.0% per year, but adds automatic 1% TSP contributions from DoD and matching contributions up to 4% of basic pay. BRS also offers a Continuation Pay bonus at 12 years of service and a lump-sum option at retirement. For service members who serve fewer than 20 years — the vast majority — BRS is significantly better because it builds retirement savings (TSP) even for those who don't reach 20 years. For career service members who serve 30+ years, the legacy High-3 system's higher multiplier may produce a larger lifetime pension. This calculator models both systems across different career lengths, pay grades, and market return assumptions to identify the total retirement wealth under each system.
High-3 Annual Pension = (Average of 3 Highest Pay Years) × 2.5% × Years of Service; BRS Annual Pension = (Average of 3 Highest Pay Years) × 2.0% × Years of Service; BRS TSP Value = Σ(DoD Matching Contributions + Personal Contributions) × Growth Factor; Total BRS Retirement Value = Pension PV + TSP Value
- 1Step 1: Enter your entry date and expected separation or retirement date.
- 2Step 2: Enter your current pay grade and expected promotion timeline.
- 3Step 3: For High-3: calculate average of 3 highest-paid years × 2.5% × service years.
- 4Step 4: For BRS: calculate pension at 2.0% multiplier, then project TSP growth with DoD matching.
- 5Step 5: Enter expected TSP contribution rate and assumed market return (default 6%).
- 6Step 6: Compare total retirement wealth (pension + TSP) under both systems at various retirement ages.
- 7Step 7: Identify the crossover point where one system outperforms the other.
High-3 pays $33,000/year lifetime vs BRS at $26,400/year plus TSP wealth. Break-even depends on life expectancy — if living to 85, BRS may equalize or exceed High-3 due to TSP value.
Under High-3, a service member who separates before 20 years receives ZERO retirement benefit — it is cliff-vested at 20 years. Under BRS, they keep all accumulated TSP contributions and DoD matching — a major advantage for the majority who separate before 20.
For a 30-year career, High-3 produces a significantly higher annual pension. The TSP advantage of BRS narrows the gap but may not overcome the $16,200/year pension difference, especially for those who die earlier.
DoD's TSP matching contributions under BRS are significant — roughly $58,000 in future value from matching alone over a 20-year career at 6% returns. This partially offsets the 0.5% multiplier reduction.
BRS allows retiring members to take 25% or 50% of the present value of their pension as a lump sum at retirement. Monthly pension is then reduced until age 67, when it restores to the full amount. Useful for those needing immediate capital but reduces long-term income.
Professionals in finance and investment use Military Retirement Brs as part of their standard analytical workflow to verify calculations, reduce arithmetic errors, and produce consistent results that can be documented, audited, and shared with colleagues, clients, or regulatory bodies for compliance purposes.
University professors and instructors incorporate Military Retirement Brs into course materials, homework assignments, and exam preparation resources, allowing students to check manual calculations, build intuition about input-output relationships, and focus on conceptual understanding rather than arithmetic.
Consultants and advisors use Military Retirement Brs to quickly model different scenarios during client meetings, enabling real-time exploration of what-if questions that would otherwise require returning to the office for detailed spreadsheet-based analysis and reporting.
Individual users rely on Military Retirement Brs for personal planning decisions — comparing options, verifying quotes received from service providers, checking third-party calculations, and building confidence that the numbers behind an important decision have been computed correctly and consistently.

Who is covered by BRS vs High-3?
Service members who entered after January 1, 2018 are automatically in BRS. Those who were serving before that date remained in High-3 unless they opted into BRS during the 2018 opt-in window. Those with fewer than 12 years of service as of January 1, 2018 had the choice to stay or switch.
What happens to TSP if I leave the military before 20 years under BRS?
Under BRS, your personal TSP contributions are always vested from day one. The DoD auto-contribution (1%) is vested after 2 years of service. The DoD matching contributions vest after 2 years. If you separate after 2 years, you keep all TSP contributions and DoD matching — a significant benefit over the legacy system where separating before 20 years means zero retirement benefit.
What is Continuation Pay under BRS?
Continuation Pay is a lump-sum bonus paid to BRS members who agree to serve a minimum additional period (typically 3 years) at their 12-year mark. Active-duty members receive at least 2.5× their monthly basic pay; the amount can be negotiated higher for high-demand specialties. This incentivizes mid-career retention and partially compensates for the reduced pension multiplier.
Is the BRS lump-sum option a good deal?
The lump-sum option allows you to take 25% or 50% of the discounted present value of your pension as an upfront payment, but your monthly pension is reduced until age 67. The discount rate used by DoD is often higher than inflation, meaning you typically receive less in total value by taking the lump sum. It is generally advisable only if you have a specific, high-return use for the capital.
How does BRS affect retirement pay for early retirees?
In the context of Military Retirement Brs, this depends on the specific inputs, assumptions, and goals of the user. The underlying formula provides a deterministic relationship between inputs and output, but real-world application requires interpreting the result within the broader context of finance and investment practice. Professionals typically cross-reference calculator output with industry benchmarks, historical data, and regulatory requirements. For the most reliable results, ensure inputs are sourced from verified data, understand which assumptions the formula makes, and consider running multiple scenarios to bracket the range of likely outcomes.
Does VA disability compensation interact with military retirement pay?
Yes. Concurrent Retirement and Disability Pay (CRDP) allows most veterans with 20+ years of service and VA disability ratings of 50% or higher to receive both full military retirement pay and VA disability compensation without offset. Combat-Related Special Compensation (CRSC) provides similar relief for combat-related disabilities. Consult DFAS for specifics.
What TSP contribution rate should I target under BRS?
At minimum, contribute 5% of your basic pay to maximize the full DoD match (DoD provides 1% auto + up to 4% match for 5% employee contribution). Contributing less means leaving DoD match money on the table. If finances allow, contributing more up to the annual IRS limit ($23,000 in 2024, plus $7,500 catch-up if 50+) is excellent for long-term wealth building.
Can I still reach financial independence under BRS if I only serve 20 years?
Yes. A BRS pension at 20 years, combined with a healthy TSP, can provide strong financial security. An E-7 at 20 years might receive $26,000/year pension + $180,000+ TSP. Combined with potential civilian employment and Social Security later, this can provide an excellent retirement income foundation — often before age 42.
Pro Tip
Use the DoD's official BRS comparison calculator at militarypay.defense.gov/Calculators/BRS to model your specific situation. Input your actual pay progression, expected TSP contribution rate, and a realistic investment return assumption. The calculator will show you which system produces more total retirement wealth at your expected career endpoint.
Did you know?
The Blended Retirement System was the most significant change to military retirement in over 70 years when it was implemented in 2018. Before BRS, approximately 83% of service members separated before 20 years and received absolutely nothing in retirement benefits — zero. BRS was designed specifically to provide some retirement benefit to the majority of service members who serve honorably but not for a full career.
