BRS Calculator 2026 — Blended Retirement Lump-Sum & Continuation Pay

What BRS is and who's on it

The Blended Retirement System was created by Public Law 114-92 (NDAA FY16, Sections 631-635) and took effect January 1, 2018. It replaces the legacy High-3 system for everyone entering active duty on or after that date. Members already serving on 31 Dec 2017 had a one-time opt-in window during 2018 that has since closed.

BRS has three distinct pieces:

Defined-benefit pension at retirement: 2.0% × YOS × high-3 (vs 2.5% under legacy High-3 — a 20% reduction).
Defined-contribution (TSP): Automatic 1% agency contribution after 60 days + matching up to 4% (after 2-year vesting for the auto 1%, starting at the 25th month of service).
Continuation Pay: A one-time bonus at the 12-year point (2.5× to 13× monthly base pay, service-specific). Requires a 3–4 year additional service obligation.

Plus an optional lump-sum election at retirement under 10 USC § 1415 — covered in detail below.

Lump-sum election — the 10 USC § 1415 math

At retirement, a BRS member may elect to receive an immediate lump-sum payment equal to the present value of 25% or 50% of their monthly retired pay that they would otherwise receive between retirement and age 67. Monthly retired pay is correspondingly reduced by 25% or 50% for that period. At age 67, the reduction ends and the retiree returns to the full unreduced amount.

The present-value calculation uses the annually-published Lump Sum Discount Rate (LSDR) from the DoD Office of the Actuary. For calendar year 2026, the rate is 6.46% per the DASD(MPP) memo dated 2025-05-22. This rate is fixed for the year — every BRS member retiring in CY2026 uses the same rate.

What the LSDR means in practice: A higher discount rate produces a smaller lump sum (more aggressive discounting of future payments); a lower rate produces a larger lump sum. At 6.46%, the lump sum is approximately 7.5–8.5× the equivalent monthly pension forgone, depending on retirement age. Compared with historical rates (4–5% in the 2018-2021 window), 2026's 6.46% is on the higher end and produces relatively smaller lump sums.

When the lump sum makes sense

The lump sum trades long-term inflation-protected income for an immediate cash payment. It can win in these scenarios:

You have a higher private-investment return target than 6.46%: If you can reliably earn >6.46% on the lump sum, you come out ahead. Historical S&P 500 returns are ~10%, but with substantial volatility and sequence-of-returns risk.
You face a major near-term capital need: paying off a high-interest debt, starting a business, buying a home outright in a high-cost area.
You have shortened life expectancy: known terminal illness, very poor health.
Tax-rate arbitrage: The lump sum is taxable in the year received (potentially pushing you into a higher bracket); the monthly pension is taxed gradually. Strategic placement during a low-income gap year can reduce total tax.

And it loses in these scenarios:

You can't reliably earn the LSDR rate: Conservative investments today yield 3–5% — well below 6.46%. The lump sum is "expensive" money for the government to give you because they assume you'll earn 6.46% on it; if you can't, you lose.
COLA on the monthly pension: The standard pension receives full CPI-W COLA (10 U.S.C. § 1401a). The lump sum locks in today's dollars; over 30 years of 2.5% inflation, the monthly stream gains substantial purchasing-power value the lump escapes.
SBP coverage: SBP premiums are deducted from monthly retired pay. A lump-sum election reduces both your monthly pay and (proportionally) the SBP base amount that can be elected.
You will live a long time: The standard pension has no end date; the lump-sum reduction does end at 67 but you give up purchasing power to get there.

Continuation Pay — the 12-year decision

At the 12-year point (between 8 and 12 years per 37 USC § 356 and DoDI 1304.31), BRS members are eligible for a one-time Continuation Pay (CP) bonus. The bonus is a multiple of monthly base pay (statutory range 2.5× to 13×) and is set annually by each service based on retention needs.

In return for accepting CP, the member commits to an additional 3–4 years of service beyond the 12-year point. CP can be taken as a lump sum or in up to 4 annual installments. CP is fully taxable in the year received.

CP multiplier ranges typical of recent years: Officers have generally received the minimum 2.5×; enlisted have ranged from 2.5× to 5× depending on AFSC/MOS/rate and service-specific retention bonuses for critically-short specialties have gone higher. The OSD CP rate memo is updated quarterly — verify your service's current rate via your career counselor or HRC/AFPC/etc. Until a specific service-CP memo is on disk, this calculator accepts your entered CP multiplier (default 2.5×) for accurate math.

BRS TSP matching — the bigger picture

BRS members receive automatic and matching contributions to their Thrift Savings Plan (TSP) from day 60 of service:

1% automatic agency contribution — credited regardless of whether the member contributes. Subject to 2-year vesting.
Matching contributions on member contributions: 1% match on the first 3% of basic pay contributed, plus 0.5% on each of the next 2% (4% match total at 5% member contribution).

Over a 20-year career, the agency match alone can yield $200,000–$400,000 in TSP value (assuming an E-5 to E-7 progression and average market returns), which the legacy High-3 system did not provide. That's the "blended" piece — BRS members give up some defined-benefit pension value in exchange for portable defined-contribution wealth that they keep regardless of whether they reach 20 years.

For separators who leave before 20 years, BRS is a clear win over High-3 (whose pension is forfeited entirely below 20 YOS). For long-career retirees who stay 30+ years, High-3's higher multiplier may produce a larger lifetime pension — though never including the TSP portability.

Lump-sum decision checklist

Before electing a lump sum at retirement, work through these:

Project your standard pension with COLA over your expected lifetime — use the comparison above as a starting point and add 2.5% annual COLA.
Compute the after-tax lump sum (lump is taxable; consult tax pro for bracket placement).
Project the after-tax growth of the invested lump sum at your realistic return assumption.
Factor in SBP coverage — lump sum reduces the base amount available for SBP, reducing surviving-spouse protection.
Factor in VA disability offset — if you have a VA rating, retired-pay waiver math interacts with both lump and reduced pension.
Confirm state tax treatment — some states exempt military retirement entirely, others tax the lump differently than the monthly.

BRS continuation pay, the lump-sum election, and the irreversibility of the BRS opt-in

The Blended Retirement System applies to every service member who entered active service on or after 1 January 2018, plus the cohort of members who entered before 1 January 2018 and elected to opt in during the opt-in window that closed 31 December 2018. The opt-in election was a one-time, irrevocable decision under the National Defense Authorization Act for Fiscal Year 2016 (Public Law 114-92), and members who opted in cannot return to the legacy High-3 system regardless of subsequent career decisions. Members who entered after 1 January 2018 are automatically enrolled in BRS and have no opt-out path. The calculator above models the BRS pension multiplier, the TSP match outlined in 5 U.S.C. § 8440e, and the continuation pay and lump-sum components defined in 37 U.S.C. § 356 and 10 U.S.C. §§ 1409 and 1415.

The 2.0% pension multiplier vs the 2.5% High-3 multiplier. BRS pension is 2.0% × YOS × High-3 average basic pay. The legacy High-3 system uses 2.5% × YOS × High-3 average. A 20-year retiree under BRS receives 40% of High-3 as monthly pension; the legacy 20-year retiree receives 50% of High-3. The 10- percentage-point reduction at 20 years is offset over a career by the BRS-only TSP matching that 5% of basic pay every pay period — capturing the full BRS match for a full 20-year career typically produces a break-even with the legacy system at retirement, with crossover depending on TSP investment performance and contribution discipline.

Continuation pay at 12 YOS. Under 37 U.S.C. § 356, BRS members are eligible for a one-time Continuation Pay bonus at 12 years of service if they commit to a minimum of 4 additional years. The multiplier is set by the secretary of the service branch and varies between 2.5 and 13 times monthly basic pay for active component members (and a separate, lower multiplier for reserve component members under § 356(b)(2)(B)). The continuation pay amount and conditions are published in service-specific instructions and rotate periodically based on retention needs. A member at the 12-YOS mark who is undecided about staying past 20 should understand that continuation pay is taxable in the year of receipt and is forfeit if the 4-year obligation is broken; an early separation triggers a recoupment of the unearned portion.

The lump-sum retirement election under 10 U.S.C. § 1415. At retirement under BRS, the member may elect to receive 25% or 50% of the present value of pension payments through age 67 as a lump sum at retirement, with the monthly pension reduced proportionally during the lump-sum period and full pension restored at age 67. The lump-sum present-value calculation uses the discount rate published annually by the Department of Defense under DoD FMR Volume 7B. The 2026 discount rate is set by USD(P&R) memorandum (the FY2026 rate was 6.46% per the DASD(MPP) Lump-Sum Discount Rate memo of 22 May 2025). The 25% lump-sum election produces a smaller lump but a smaller monthly reduction; the 50% election produces a larger lump but a larger monthly reduction. The election is irrevocable once made. Members evaluating the lump-sum should treat it as a tax-event decision — the lump sum is taxable in the year of receipt and is often taxed at the highest marginal bracket. For most retirees, the 0% election (no lump sum) maximizes lifetime after-tax pension value at the cost of forgoing the lump-sum cash.

BRS vs High-3 break-even. The most defensible heuristic for the BRS-vs-High-3 decision (for members who had the opt-in choice in 2018) is to model both systems forward with a realistic TSP return assumption and the member's actual contribution history. Members who would consistently capture the full 5% BRS match throughout a 20-year career typically come out ahead under BRS at retirement if the TSP achieves long-run real returns above 4%. Members who would skip TSP contributions or contribute below 5% are meaningfully worse off under BRS because they would lose 20% of the legacy pension without capturing the offsetting employer match. The calculator above models both paths with adjustable TSP contribution and return assumptions.

BRS — frequently asked questions

What is the BRS Lump-Sum Discount Rate for 2026?

The Lump-Sum Discount Rate (LSDR) for calendar year 2026 is 6.46%, published by the DoD Office of the Actuary via DASD(MPP) memo signed May 22, 2025. The rate is fixed for any BRS retirement eligible to begin receiving retired pay between January 1, 2026 and December 31, 2026. Authority: 10 U.S.C. § 1415. The next rate (for CY2027) will be published June 2026.

How is the BRS lump sum calculated?

You may elect to receive an immediate lump sum equal to the present value of 25% or 50% of your monthly retired pay forgone from retirement to age 67. The present value uses the current LSDR (6.46% for 2026). After the lump, your monthly retired pay is reduced by 25% or 50% to age 67, then restores to the full amount for life.

BRS vs High-3 — which is better?

BRS has a 2.0% per-YOS multiplier (vs 2.5% under legacy High-3) — a 20% smaller pension. In exchange, BRS adds TSP automatic 1% + matching up to 4% (after 2-year vesting on the auto 1%), Continuation Pay at 12 YOS, and the lump-sum election. For separators who leave before 20 YOS, BRS wins because TSP is portable. For long-career 30+ YOS retirees, High-3 produces a larger pension but BRS adds substantial TSP value.

What is Continuation Pay?

A one-time bonus at the 12-year point (statutory range 2.5× to 13× monthly basic pay per 10 USC § 356) in exchange for 3-4 additional years of service. The multiplier varies by service and AFSC/MOS/rate, updated quarterly via OSD memos. Officers have generally received the minimum 2.5×; enlisted critical specialties have ranged higher. Verify your service's current CP rate with your career counselor.

Should I take the lump sum?

Generally not, unless you have a higher reliable investment return target than 6.46%, a major near-term capital need, shortened life expectancy, or specific tax-rate-arbitrage gain. Reasons to skip: COLA on the standard pension typically adds 50–80% lifetime value the lump escapes; SBP base amount shrinks proportionally; tax bracket pushed up by lump receipt. Run the math with COLA before deciding.
