The blended retirement system brs is the retirement plan that applies to every servicemember who joined the U.S. military on or after January 1, 2018.
According to the Department of Defense, roughly 83% of new entrants were not expected to serve the 20 years needed for a legacy pension, which is why the blended retirement system brs was designed to give more people portable retirement savings.
The problem is that many servicemembers enroll without understanding how the three components work together, leaving government matching dollars on the table.
This article breaks down how the pension, Thrift Savings Plan contributions, and government matching fit together, how the continuation pay bonus works, and the steps you can take to maximize every dollar the blended retirement system brs offers you.
What Is the Blended Retirement System?
The blended retirement system combines a reduced defined-benefit pension with a defined-contribution plan, similar to a 401(k). Under the blended retirement system brs, the pension multiplier is 2.0% per year of service instead of the legacy 2.5%, meaning a 20-year retiree earns 40% of their average highest 36 months of base pay rather than 50%.
The trade-off is that you gain ownership of retirement savings you keep even if you leave before 20 years. The DoD notes that under the legacy "High-3" system, most servicemembers who separated earlier received no retirement benefit at all from their years of service — a gap the blended retirement system brs was created to close.
How to apply this: Log into MyPay and confirm your retirement system designation so you know exactly which rules apply to you.
How the Thrift Savings Plan Fits Into BRS
The blended retirement system brs automatically enrolls you in the Thrift Savings Plan with 1% of your basic pay contributed by the government, whether you save anything or not. Your own contributions are then matched up to 5% of basic pay: 100% match on the first 3% and 50% on the next 2%.
That means contributing 5% captures the full government match — the fastest "free money" available to you under the blended retirement system brs. The Federal Retirement Thrift Investment Board, which administers the TSP, reports that participation among new military entrants under automatic enrollment far exceeds the voluntary rates seen before BRS.
Vesting Rules You Cannot Ignore
- Government automatic 1% contributions require 2 years of service to vest.
- Your own contributions and the matching dollars vest immediately.
- Leaving before 2 years forfeits only the automatic 1% and its earnings.
How to apply this: Set your TSP contribution to at least 5% of basic pay in MyPay this week — waiting costs you matching dollars you can never recover.
Continuation Pay: The Mid-Career Bonus
Between your 8th and 12th year of service, the blended retirement system brs offers continuation pay in exchange for a service commitment. Active-duty members receive at least 2.5 times their monthly basic pay; Reserve and Guard members receive at least 0.5 times their monthly pay for the agreement period.
Individual branches set their own continuation pay amounts, and many offer more than the blended retirement system brs minimum to retain skills in critical career fields. Accepting the bonus creates an obligation to serve an additional period, so weigh the timing against your career plans.
How to apply this: Ask your personnel office or check your branch's guidance for the exact continuation pay window and multiplier for your career field.
Opt-In and Opt-Out Deadlines
Servicemembers with prior service before 2018 — those with fewer than 12 years of service as of December 31, 2017, and some who broke service — were allowed to opt into the blended retirement system brs during 2018. That opt-in window is now closed, so most current members are permanently assigned to one system.
New entrants today are automatically placed in the blended retirement system brs and cannot opt out. The Department of Defense's official BRS resources at militarypay.defense.gov explain the eligibility rules and provide calculators.
How to apply this: If you're unsure which system you're in, request your retirement system designation from your servicing personnel office in writing.
Comparing BRS to the Legacy High-3 System
Here's how the blended retirement system brs stacks up against the legacy plan side by side:
| Feature | Blended Retirement System | Legacy High-3 |
|---|---|---|
| Pension multiplier | 2.0% per year | 2.5% per year |
| Government TSP contribution | Automatic 1% + match up to 5% | None |
| Benefit if you leave early | Keep TSP money (after vesting) | No pension |
| Continuation pay | Yes, 8–12 year window | No |
| 20-year pension value | 40% of High-3 average | 50% of High-3 average |
| Lump sum option | Available at retirement | Not available |
| Best for | Shorter careers | Certain 20+ year careers |
The right choice depends on career length, but for those in the blended retirement system brs the decision now is about maximizing contributions, not switching systems. Run your numbers with the official DoD comparison calculator before major career decisions.
How to apply this: Use the DoD's comparison calculator annually as your pay changes to model both outcomes.
Lump Sum Option at Retirement
At retirement, blended retirement system brs members may take a discounted lump sum of a portion of their future pension (25% or 50%) in exchange for reduced monthly payments until full retirement age. The discount rate is set by law and the DoD publishes the assumed rates annually.
This option suits those with a specific use for capital — paying off debt or starting a business — but the discount means most financial counselors advise caution. Per the DoD's blended retirement system brs guidance, lump sum elections require financial counseling as part of the retirement process.
How to apply this: Before separating, schedule the mandatory retirement counseling session and model lump sum scenarios with a DoD-authorized financial counselor.
Frequently Asked Questions About blended retirement system brs
How does BRS affect reservists and National Guard members?
Reservists and Guardsmen are covered by the blended retirement system brs with the same structure, but the rules scale with points and drill pay. Your government match is based on basic pay earned during drilling periods, so you control the match rate by contributing a percentage of each drill paycheck.
If you have broken service or a long gap, a personnel office can calculate how it affects vesting and continuation pay eligibility.
What happens to my TSP if I leave the military before retirement?
Your TSP account stays yours under the blended retirement system brs and continues to grow tax-advantaged. You can leave the funds in TSP, roll them into an IRA or a civilian employer's 401(k), or withdraw them (with taxes and possible penalties before age 59½).
One exception: contributions you made from tax-exempt combat zone pay carry special withdrawal treatment, so review your account statements before moving money.
Can I change my TSP contributions anytime under BRS?
Yes — under the blended retirement system brs, contribution elections through MyPay generally take effect within one or two pay cycles, and you can adjust them as often as your service allows. A common scenario: many members raise their contribution during deployment, when pay is tax-exempt, to maximize tax-advantaged growth.
Set a calendar reminder to review elections after every promotion or pay raise.
Does the lump sum option make sense for everyone?
No, and it's not required — declining it preserves your full monthly annuity. It may fit those with high-interest debt or an immediate business need, but the blended retirement system brs applies a discount rate that reduces the lump sum's value relative to future payments.
If you expect a civilian pension or Social Security timing that depends on age, model both paths before electing anything at your retirement processing appointment.
How does BRS interact with VA disability compensation?
VA disability compensation is separate and does not reduce your TSP or continuation pay in any way. Where interaction matters is the pension itself: blended retirement system brs retired pay may be offset by disability pay unless you qualify for Combat-Related Special Compensation or Concurrent Retirement and Disability Pay.
Check the VA's concurrent receipt rules when you file your claim so you can plan your expected retirement income accurately.
Conclusion
Understanding the blended retirement system brs comes down to three moves: contribute at least 5% to capture the full match, plan for continuation pay in your 8–12 year window, and know your vesting timeline. Key takeaways:
- The 1% automatic contribution vests after 2 years; match dollars vest immediately.
- Continuation pay is a guaranteed bonus opportunity — mark your window.
- The lump sum is optional and often better declined.
Open your TSP account settings today, confirm your contribution is at least 5%, and schedule a session with your installation's Personal Financial Counselor to build your full blended retirement system brs retirement roadmap.
