Military retirement and FIRE

Few careers offer what military service can: a pension that can start right after 20 years of active duty, which for someone who joined young can be before 40. Add Thrift Savings Plan savings and health coverage, and a service member can be a long way toward financial independence at the point most civilians are mid-career.

But the system changed in 2018, not everyone who joins serves 20 years, and the pension alone rarely covers everything. This guide explains the pieces and how they fit a FIRE plan.

This is general education, not advice. Military pay and benefit rules are detailed and change. Confirm your own situation with your service's finance office, a personal financial counselor (available at no cost through Military OneSource) and the official sources linked below.

The Blended Retirement System

Military OneSource describes the BRS's main parts (Military OneSource):

The pension (defined benefit)

• You must serve at least 20 years to receive regular retired pay. Leave before 20 and you generally get no pension payment. The exception is disability retirement: members found unfit for duty because of a qualifying disability can receive retired pay with fewer than 20 years (DoD).
• For active duty, the formula is 2% × years served × your high-3, the average of your highest 36 months of basic pay. For Guard and Reserve retirement, the years in the formula generally come from your retirement points divided by 360, not the number of qualifying years (DoD).
• Under the legacy High-3 system, which covers many members who joined before 2018, the multiplier is 2.5%.

A made-up example: a member retires from active duty after 20 years with a high-3 of $60,000.

• BRS: 2% × 20 × $60,000 = $24,000 a year (40% of high-3).
• Legacy High-3: 2.5% × 20 × $60,000 = $30,000 a year (50% of high-3).

Each additional year of service adds to the percentage.

The TSP (defined contribution)

• After 60 days of service, the government contributes 1% of your basic pay to your TSP, even if you contribute nothing.
• Starting in your third year, it matches your contributions, up to an additional 4%. Contribute 5% and the government puts in 5% in total (Military OneSource, DoD BRS fact sheet).
• After two years of service you're vested, so the whole TSP account goes with you if you leave.

For 2026, the TSP's employee contribution limit is $24,500, the same as a 401(k), with catch-ups from 50 (IRS). The TSP offers traditional and Roth options.

Continuation pay and the lump-sum option

• Continuation pay: between 7 and 12 years of service, you can receive a cash payment for agreeing to serve at least three more years (Military OneSource). Where it goes, savings or spending, is a FIRE decision in itself.
• Lump sum at retirement: BRS retirees can take 25% or 50% of the discounted value of their pension up front, in exchange for reduced monthly payments until age 67, when the full amount resumes (Military OneSource). Because it's a discounted value, the lump sum is generally less than the payments you give up. Pension check or lump sum? covers the general trade-offs.

When the pension starts

For active-duty retirees, retired pay generally starts when you retire. For the Guard and Reserve, members with 20 qualifying years are generally not eligible for retired pay until age 60, though certain active service after January 28, 2008, can reduce that age, to no earlier than 50 (DoD). That gap matters a lot for a reservist planning early retirement.

Inflation protection

Military retired pay is adjusted each year based on the Consumer Price Index. For example, most retired pay rose 2.8% effective December 1, 2025 (DFAS, DoD). That means a military pension can cover a steady share of spending over decades, which shrinks how much you need to have saved.

Health coverage: TRICARE

Health insurance is often the biggest obstacle to early retirement. Retired service members and their families under 65 may qualify for TRICARE Prime or TRICARE Select, among other options (TRICARE). Guard and Reserve retirees under 60 may qualify to purchase TRICARE Retired Reserve.

Later, if you become eligible for Medicare, you generally must have Medicare Part B to keep TRICARE; with Parts A and B you can use TRICARE For Life (TRICARE). Plan for the Part B premium, which for 2026 is $202.90 a month in the standard case (CMS).

Civilians retiring early should compare this with Health insurance before Medicare: it's a big part of why a military pension can be such a strong FIRE foundation.

Building a FIRE plan around a military pension

Size the gap

The pension covers part of your spending. Savings cover the rest.

Continuing the made-up example: if your family spends $50,000 a year and the BRS pension pays $24,000, savings need to cover about $26,000. In the simple 4% rule model, that's about $650,000 ($26,000 × 25), much less than the $1,250,000 you'd need with no pension. Our Pension FIRE calculator does this math with your own numbers.

Remember that retired pay is generally taxable income for federal purposes (IRS Pub 3); state rules vary.

Don't count on 20

Plenty of military careers end before 20 years, by choice, by injury or because of how careers unfold. Under the BRS, that generally means no regular retirement pension but a portable TSP. A career ended by an injury or illness that leaves a member unfit for duty may lead to disability retirement or disability severance pay instead, depending on the disability rating (DoD). A plan that works without the pension, and gets better with it, is sturdier than one that depends on it.

Survivor coverage

At retirement, you'll decide whether to enroll in the Survivor Benefit Plan, which can continue part of your retired pay to a spouse or children after your death, for a cost. It's a major decision; DFAS has details on its retired military pages.

VA disability

VA disability compensation is a separate benefit from retired pay, and the rules about receiving both are complex. VA.gov is the place to start.

The second career

Retiring from the military in your late 30s or 40s often isn't the end of work. It's a choice about what comes next. Some veterans use the pension as a floor and take a job they love for less pay. Some go to school, start a business, or work part-time and call it Barista FIRE. Some take a civilian job and save most of it to reach full financial independence within a few years.

Ideas:

• Use your skills. Leadership, logistics, medical, technical and security experience transfer to many fields. See Side hustles that use the skills you already have.
• Use education benefits if you have them. VA.gov explains the GI Bill.
• Think about purpose, not just pay. Leaving a mission-driven career can be harder than people expect. Our Purpose page and What will you retire to? can help.
