Retirement

Retirement planning before you have even shipped to BMT sounds premature. It isn't. The contribution choice you make in your first weeks of service compounds for decades, and BRS is built so that time in uniform builds real, portable wealth whether you serve four years or thirty. The mechanics get technical in places. That is deliberate: your money deserves the precision.

Blended Retirement System: three parts, no opt-in

BRS became mandatory for everyone entering military service after January 1, 2018 (1). If you enlist today, this is your system. There is nothing to opt into. It combines three pieces: a traditional pension (the "defined benefit"), government-matched contributions to the Thrift Savings Plan (TSP), and a one-time mid-career bonus called Continuation Pay. It replaced the legacy "High-3" plan, which paid a larger pension but gave absolutely nothing to the more than 80% of members who separated before reaching 20 years (1).

The pension: 20 years for lifetime pay

Complete 20 years of creditable service and you qualify for a lifetime monthly pension with annual Cost-of-Living Adjustments. The formula is simple: years of service times a 2.0% multiplier, applied to your "High-3," the average of your highest 36 consecutive months of basic pay. Only base pay counts; allowances like BAH and BAS are excluded. That produces 40% of your High-3 at 20 years and 60% at 30, paid for life and adjusted annually for inflation (2).

The legacy High-3 used a 2.5% multiplier, so it paid 50% at 20 years against BRS's 40%. On paper BRS retirees look shortchanged. In practice, TSP matching and portability close much of that gap, and mathematical modeling shows that when contributions are invested early and left to compound, BRS can actually exceed the legacy system's value for many members. For the vast majority who never reach 20 years, it isn't close: BRS gives them something, the old system gave them nothing (1).

At retirement, BRS also offers a lump sum option: take 25% or 50% of the discounted present value of your future retired pay upfront, in exchange for reduced monthly checks until full Social Security retirement age (67 for most people today). The DoD sets the applicable discount rate each June (3). The option exists, but financial advisors almost universally warn against it. The math rarely favors the lump sum.

TSP matching: the free 5% most people miss

This is where BRS gets genuinely valuable for a new enlistee. The government puts money into your TSP two ways (1):

The automatic 1%. Starting 60 days after you enter service, the government deposits 1% of your basic pay into your TSP every pay period. You contribute nothing and it still happens.

The 4% match. Beginning at your 25th month of service (the start of your third year), the government matches what you contribute on a tiered scale: your first 3% of basic pay dollar-for-dollar, the next 2% at 50 cents on the dollar. Contribute 5% and the government adds 4%, which stacks with the automatic 1% for a full 5%.

So contributing 5% of your basic pay sends 10% of your pay into retirement every month: your 5% plus the government's 5%. Contributing less than 5% forfeits part of that match, the closest thing to free money the pay system offers (1). New members are auto-enrolled at 5% (raised from the original 3% on October 1, 2020), which conveniently captures the entire match; you can change or stop it, but if you opt out you are re-enrolled each January, into an age-appropriate L Fund by default (17).

Continuation Pay: a bonus for four more years

Somewhere between your 8th and 12th year (the Air Force typically pays it at the 12-year mark), you receive a one-time bonus called Continuation Pay in exchange for committing to at least four more years (4). Active Duty members get 2.5 times their monthly basic pay; Guard and Reserve drilling members get 0.5 times (AGR and full-time support personnel get the active-duty rate) (4). An E-6 past 12 years earning roughly $4,100 a month would see about $10,250 as active-duty continuation pay, taken as a lump sum or spread over up to four annual installments. Many members drop it straight into their TSP. Other branches use different windows, so numbers you hear from friends in other services may not match (4).

Vesting: you keep the match after just two years

This is what makes BRS fundamentally different from what came before. You keep the government's TSP contributions even if you leave before 20 years. The automatic 1% and all matching vest after 2 years of service; your own contributions are yours immediately (1).

Under the old system, a member who served 19 years and 364 days walked away with zero retirement. Under BRS, someone who serves a single four-year enlistment while contributing 5% leaves with years of government-matched savings. When you separate, the account stays open: leave it in the TSP for those rock-bottom fees, roll it into an IRA or a new employer's 401(k), or withdraw it, though pulling a Traditional balance before age 59 1/2 brings taxes and an early-withdrawal penalty. For the roughly 81% of members who never reach 20 years, that portability is a transformational change (1).

The Thrift Savings Plan

The TSP is the government's retirement savings program, the military's answer to a civilian 401(k). Its edge is cost. Expense ratios run roughly 0.034% to 0.047% (2025), lower than 99% of all funds tracked by FactSet, against an industry average of 0.5% to 2.0% for mutual funds (5). Over a 20-year career, that gap alone can mean tens of thousands of extra dollars.

Where your money goes: the funds

TSP offers five core funds plus Lifecycle (target-date) funds. You do not need to be a financial expert to use them:

• G Fund (Government Securities): special U.S. Treasury securities. Principal is government-guaranteed, so you can't lose money; the tradeoff is the lowest long-term growth. The rate resets monthly on the weighted average yield of longer-dated Treasury notes and bonds.
• F Fund (Fixed Income): tracks the Bloomberg U.S. Aggregate Bond Index (government, corporate, and mortgage-backed bonds). More growth potential than G, but the balance moves with the bond market.
• C Fund (Common Stock): tracks the S&P 500, the 500 largest U.S. companies. Historically the highest long-term returns of the core funds, with more volatility to match.
• S Fund (Small Cap): tracks the Dow Jones U.S. Completion index, the small and mid-sized companies outside the S&P 500. Higher growth potential, higher volatility.
• I Fund (International): exposure to international markets. Since October 2024 it tracks the MSCI ACWI IMI ex USA ex China ex Hong Kong Index: over 5,500 stocks across 44 countries, a major broadening from the old MSCI EAFE Index (roughly 800 stocks in 21 developed markets). China and Hong Kong were dropped after an independent review cited delisting risks and sanctions uncertainty (6).
• L Funds (Lifecycle): target-date funds that shift from aggressive to conservative as your date nears, offered from L 2030 through L 2075 in five-year steps, plus L Income for those already withdrawing. Not sure how to allocate? Picking the L Fund closest to when you turn 62 is a reasonable default.

Traditional vs. Roth: pay taxes now or later

You can make contributions Traditional (pre-tax) or Roth (after-tax), or split them any way you like (7).

Traditional lowers your taxable income now; you pay tax later when you withdraw in retirement. It makes sense if you expect a lower tax bracket then than today. Roth uses money you have already been taxed on, and the payoff comes later: qualified withdrawals, including decades of investment growth, come out completely tax-free. For junior enlisted members in low brackets, Roth is usually the stronger play, a small tax bill now to dodge a much larger one later (7).

Roth gets even better in a combat zone. Combat pay is already tax-exempt, so contributing it to Roth TSP produces a "triple tax advantage": the money goes in tax-free, grows tax-free, and comes out tax-free. That is about as good as the tax code gets.

One catch: all government matching and automatic contributions always land in your Traditional balance, whatever you elect for your own money. Since 2026, TSP allows Roth in-plan conversions (up to 26 per calendar year) (8), which is useful for converting those Traditional government dollars in a low-bracket year. You can change your contribution percentage or your Traditional/Roth split anytime in myPay; it takes effect the next available pay period.

Contribution limits

The Annual Additions Limit matters most for combat zone contributions: tax-exempt pay contributed to Traditional TSP bypasses the normal elective-deferral cap and counts only toward this higher ceiling, a real wealth-building lever for deployed Airmen (9). The "super catch-up" for ages 60 through 63 comes from the SECURE 2.0 Act and took effect January 1, 2025. Under the same law, starting January 1, 2026 anyone who earned more than $150,000 the prior year must make all catch-up contributions as Roth, with no Traditional catch-up option for high earners (8).

The matching trap: don't front-load

One of the most common and costly mistakes members make. Because matching is calculated per pay period, hitting your annual cap early means zero contributions, and zero match, for every pay period left in the year. Say an E-5 over 6 sets a very high percentage and maxes the $24,500 limit by August: the match disappears for September through December, four months of free money gone. The fix is to spread contributions evenly across all 12 months, and the TSP "How Much Can I Contribute?" calculator does the math for you (10). As a new enlistee your pay is too low to hit the cap, so this won't bite right away, but the principle matters as your career and pay climb.

Guard and Reserve: points, not years

If you are weighing the Air Force Reserve or Air National Guard, retirement runs on a different clock. Instead of crediting years directly, Reserve Component members accumulate retirement points, and pension payments do not begin until age 60 (sometimes earlier). TSP matching, though, is identical to Active Duty: the same automatic 1% and up-to-4% match, applied to your basic pay for drill weekends, annual training, and any other paid military duty.

Earning points, and what a "good year" means

Members earn points several ways (11):

The most creditable points in any anniversary year is 365 (366 in leap years), and inactive-duty points (drills, correspondence courses, funeral honors) are capped at 130 per year for retirement years ending on or after October 30, 2007 (11).

A qualifying year, a "good year," requires at least 50 points in your anniversary year, and you need 20 good years (they don't have to be consecutive) to be eligible (11). The math favors a normal drilling member. One weekend a month is about 48 drill points (4 periods x 12 months); add two weeks of annual training (14 points) and the automatic 15 membership points, and you're near 77 points a year without any extra active duty, comfortably above the 50-point floor. The danger is missing multiple drills without making them up, or a break in service: fall short of 50 and that year simply doesn't count toward your 20.

When the checks start (usually age 60)

Unlike Active Duty retirees, who draw pay immediately, Guard and Reserve members typically wait until age 60. This is formally "non-regular retirement" under 10 USC Chapter 1223 (12).

There is a meaningful exception. For each aggregate 90 days of qualifying active duty in a fiscal year after January 28, 2008, the age-60 start drops by 3 months; since September 30, 2014 those 90 days can span two consecutive fiscal years. The floor is age 50 (12). Not everything counts: mobilizations, deployments, and certain Title 10 or Title 32 federal-emergency orders qualify, but routine annual training, State Active Duty called by a Governor, and AGR service do not (12). A member with 450 days of qualifying mobilization, for example, could start at 58 years, 9 months (450 divided by 90 is 5 periods, times 3 months each, is 15 months earlier).

The gray area: eligible, but not yet paid

Finish 20 qualifying years but not yet reach your pay-start age and you land in the "gray area," a wait that can run years, sometimes over a decade. During it you keep your military ID card, commissary and exchange and MWR privileges, and the option to buy TRICARE Retired Reserve, a premium-based plan, not the subsidized TRICARE that active-duty families receive (13).

What you do not get: pension payments or standard TRICARE Prime or Select coverage. And a detail that catches many people off guard: even if qualifying active duty reduces your retirement age below 60, TRICARE eligibility still doesn't begin until age 60 (13). A member drawing retired pay at 53 would carry TRICARE Retired Reserve (which can top $1,000 a month for family coverage) or other insurance for seven more years. Advocacy groups keep pushing to align TRICARE with the reduced pay age, but no such law has been enacted as of early 2026.

The Reserve pay formula

The formula converts your career points into equivalent years of service (12):

(Total Career Points / 360) x Multiplier x High-3 Average Basic Pay

Under BRS the multiplier is 2.0%. Take a member with 4,000 career points: 4,000 divided by 360 is about 11.11 equivalent years; times 2.0% is 22.22% of the High-3. One quirk works in your favor: the High-3 uses the pay tables in effect during the 36 months right before your pay begins (usually around age 60), not when you stopped drilling, and your years of service for pay-table purposes keep accruing through the gray area (12). Annual pay raises compound across those years, so your eventual pension is higher than the tables showed the day you stopped drilling.

Active Duty vs. Reserve: side by side

Choosing between the Air National Guard and Air Force Reserve? Their federal retirement benefits are identical: same point system, same formulas, same age rules. The differences are command structure (ANG has dual state and federal missions; the Reserve is federal only) and some state-specific perks. Several states exempt military retirement pay from income tax or add tuition assistance for ANG members, but those vary widely and change often (14).

Recent changes worth knowing

FY2025 NDAA, a historic pay raise. Signed December 23, 2024 (P.L. 118-159), the FY2025 NDAA authorized the largest military pay raise since 2002: 4.5% across the board effective January 1, 2025, plus a further roughly 10% for E-1 through E-4 (Section 601) effective April 1, 2025, for a combined jump of about 14.5% for junior enlisted (15). An E-1's annual basic pay went from about $24,206 to $27,828. It matters for retirement because higher basic pay lifts both your TSP match and, for career members, your High-3 average.

FY2026 NDAA and the Warrior Dividend. The FY2026 NDAA (P.L. 119-60), signed December 18, 2025, set a 3.8% raise for 2026 and added the "Warrior Dividend," a one-time, tax-free $1,776 payment to about 1.45 million active-duty members in grades O-6 and below (16). Structured as a supplemental BAH payment, it does not touch base pay, retirement calculations, or recurring benefits.

SECURE 2.0, beyond the catch-up. Besides the super catch-up and Roth in-plan conversions covered above, SECURE 2.0 also raised the Required Minimum Distribution start age (73 now, rising to 75 in 2033) and exempts Roth balances from RMDs entirely (8).

TERA has expired. Temporary Early Retirement Authority, which had allowed retirement with 15 to 20 years of service, expired December 31, 2025. It had been dormant since February 2018 and was not extended in recent legislation (18).
