Marine Retirement and BRS Guide

Military retirement is a long-term benefit that rewards career service. For a Marine entering today, the relevant system is the Blended Retirement System (BRS), which combines a traditional pension with a Thrift Savings Plan (TSP) account, a mid-career continuation pay, and an optional lump-sum election at retirement. Understanding each piece separately is more useful than treating BRS as one monolithic benefit.

Who is on BRS and who is on the old system

Service members with a date of initial entry into military service on or after January 1, 2018 are automatically enrolled in BRS. There is no opt-out. Marines entering today are on BRS by default.

Service members who entered before January 1, 2018 and did not opt into BRS during the election window that closed December 31, 2018 remain on the legacy High-3 system. High-3 is simpler: it is a straight pension with no TSP matching and no continuation pay structure. A legacy service member who reaches 20 years receives 50% of their high-36 average basic pay as a monthly pension. No TSP matching, no continuation pay carve-out.

Most Marines serving today who are early in their career are on BRS. Legacy High-3 members are typically mid-career or senior. Understanding which system applies is the first step before any retirement planning calculation.

BRS: the pension piece

The BRS pension uses a formula:

2% per year of service multiplied by the high-36 average basic pay

At 20 years, that equals 40% of the high-36 average. The pension pays monthly for the rest of the Marine’s life starting at the retirement date.

High-36 means the average of the 36 highest-paid months of basic pay, which in most careers is the final three years before retirement. A Marine who promotes steadily will have a higher high-36 than one who spent those final three years at a lower grade.

For a concrete example using 2026 figures: an E-8 Master Sergeant retiring at 20 years, with a high-36 average of approximately $6,995 per month (the current E-8 at-20-years rate), would receive:

• Monthly pension: 40% × $6,995 = $2,798 per month
• Annual pension: approximately $33,578 per year

For an O-4 Major retiring at 20 years with a high-36 average of approximately $10,400 per month (based on the O-4 rate in the over-18-year column):

• Monthly pension: 40% × $10,400 = $4,160 per month
• Annual pension: approximately $49,920 per year

These are illustrative figures based on the verified 2026 DFAS pay tables. Actual high-36 averages depend on promotion timing and the specific pay rates in the final three years.

The BRS pension is lower than the legacy High-3 pension at equivalent years of service because BRS trades some pension percentage in exchange for the TSP matching benefit. The full comparison requires accounting for TSP value, which is addressed below.

BRS: the TSP piece

TSP is the federal government’s version of a 401(k) retirement savings account. Under BRS, the government contributes to a Marine’s TSP account in two ways.

Automatic contribution. Starting 60 days after entry on active duty, the government automatically contributes 1% of basic pay per month to the Marine’s TSP account. This happens regardless of whether the Marine contributes anything. It vests at two years of service.

Matching contributions. Starting at the beginning of the third year of service, the government matches the Marine’s own contributions:

• 100% match on the first 3% the Marine contributes
• 50% match on the next 2% the Marine contributes
• Maximum total government match: 4% per month
• Total maximum government contribution when adding the 1% auto: 5% of basic pay per month

To receive the full match, the Marine must contribute at least 5% of basic pay to TSP. If the Marine contributes less than 5%, they leave government matching money uncollected.

For an E-4 Corporal at 2 years of service earning $3,303.00 in monthly base pay:

• 5% contribution from the Marine: $165.15 per month
• Government match (4%) plus auto (1%): $165.15 per month in government contributions
• Total monthly TSP contribution: $330.30 per month

Over a 20-year career, consistent contributions compounding over time build a TSP balance that meaningfully supplements the pension. The pension covers the first layer of retirement income. TSP covers the variable investment layer that can grow beyond the pension’s fixed amount.

TSP offers both traditional (pre-tax) and Roth (post-tax) contribution options. Active-duty Marines in combat zones can contribute to Roth TSP using tax-free pay, which is a significant tax advantage not available in most civilian 401(k) programs.

TSP matching in practice for junior Marines

The most common mistake junior Marines make with TSP is not contributing at all, or contributing less than 5% and leaving government money uncollected.

The BRS automatic 1% contribution begins without any action from the Marine after 60 days. But the matching contribution requires the Marine to actively elect a contribution through the myPay portal. A Marine who never sets up a contribution gets only the automatic 1%, missing 4% per month in matching.

A Marine who contributes 5% starting at year three captures the full government match. Every month of matching left uncollected is money permanently lost. There is no catch-up mechanism for missed matching periods.

The habit of contributing 5% is more important than the specific funds chosen within TSP. The government’s Lifecycle (L-fund) options are reasonable defaults for Marines who do not want to actively manage fund allocation.

Continuation pay

BRS includes a mid-career continuation pay designed to retain Marines at a critical decision point. The Marine Corps pays a cash bonus in exchange for a minimum three-year service commitment.

The continuation pay window is between 8 and 12 years of service. Active-component Marines who accept continuation pay receive between 2.5 times and 13 times their monthly basic pay as a lump-sum payment, in exchange for at least three more years of service.

The multiplier range varies. Active-component Marines typically receive 2.5 times monthly basic pay as the baseline. High-demand MOSs may receive higher multipliers. The specific offer depends on the year and the Marine’s occupational field.

For an E-7 Gunnery Sergeant at 10 years earning $5,300.40 per month in base pay, a 2.5 multiplier continuation pay would be approximately $13,251. A Marine in a higher-demand technical field at the same grade and service time could receive significantly more.

Continuation pay is taxable income. Taxes on a lump-sum payment at that level can be meaningful. A Marine receiving a large continuation pay should expect a tax withholding that reduces the take-home significantly below the gross amount.

Accepting continuation pay and then separating before completing the three-year obligation requires repayment. The commitment is real.

Lump-sum election at retirement

At the point of retirement, BRS offers the option to take a one-time lump-sum payment in exchange for a reduced monthly pension until age 67.

The options are 25% or 50% of the discounted present value of future pension payments. Taking the lump sum reduces the monthly pension by the same percentage (25% or 50%). At age 67, the pension restores to its full amount.

The math for whether the lump sum is worth taking depends on individual circumstances: life expectancy, investment ability, immediate cash needs, and the discount rate used in the calculation. The government’s calculation uses a specific discount rate that generally makes the lump sum less financially efficient than collecting the full monthly pension from day one, but individual situations vary.

For most Marines, taking the full monthly pension from retirement day forward without the lump-sum reduction is the simpler and typically more valuable long-term choice. The lump sum exists for situations where a large upfront cash amount has specific value, such as paying off a mortgage, starting a business, or covering other high-priority financial obligations at retirement.

Legacy High-3: who is still on it and how it works

High-3 is the pre-BRS pension system. It applies to service members who entered before January 1, 2018 and did not opt into BRS.

The High-3 formula:

• 2.5% per year of service multiplied by the high-36 average basic pay
• At 20 years: 50% of high-36 (compared to 40% under BRS)
• At 30 years: 75% of high-36

High-3 has no government TSP matching. No continuation pay framework. It is a straight defined benefit pension that only pays if the Marine reaches 20 years. Before 20 years, a High-3 service member who separates receives nothing from the retirement system. There is no portable TSP balance that vests early as there is under BRS.

The Higher pension percentage at 20 years is the trade-off against BRS’s portable TSP benefit. A High-3 Marine who retires at 20 years receives 50% of high-36 versus 40% under BRS. The question is whether the TSP matching accumulated over a BRS career makes up the 10-percentage-point pension difference. For most Marines who contribute consistently to TSP under BRS, the total retirement wealth is comparable to or greater than High-3, depending on investment returns.

The 20-year cliff and what it means

Military retirement is sometimes called a “20-year cliff” because the pension has a steep threshold. Under both BRS and High-3, a Marine who separates at 19 years receives no pension. The pension only pays to those who complete at least 20 qualifying years of service.

Under BRS, this is softened slightly. The TSP matching contributions belong to the Marine after the auto-contribution vests at two years. A Marine who separates at 10 years takes no pension but does take a TSP account with government matching contributions. That is a meaningful improvement over High-3, where a 10-year veteran leaves with nothing from the retirement system.

But the pension itself still requires 20 years. For a Marine entering at 18, that means committing to a career through age 38 at minimum. The pension is real and valuable, but it requires treating the Marines as a long-term career rather than a single enlistment.

Marines who are uncertain about staying for 20 years should still contribute 5% to TSP to capture the government match. If they separate at year 8 or year 12, the TSP balance is theirs to roll over into an IRA or civilian 401(k). It is not tied to the pension in any way.

Reserve retirement

Marine Corps Reserve retirement works differently from active-duty retirement. The system is points-based rather than years-of-service based, and the pension typically begins at age 60 rather than at separation.

Points. Reserve Marines accumulate retirement points through:

• 1 point per day of active duty (deployments, activations, schools)
• 1 point per drill period of inactive duty training (typically 2 points per weekend drill)
• 15 gratuitous points per year for reserve membership
• Additional points for correspondence courses and other qualifying activities

Qualifying years. A “good year” requires 50 or more retirement points. Twenty good years qualifies a reserve Marine for retirement. A Marine who does two weekend drills per month plus annual training typically accumulates around 75 points per year and can reach 20 qualifying years in 20 calendar years.

The pension formula. At retirement eligibility, the points are converted to equivalent years of service for the formula. The calculation uses points divided by 360 to convert to equivalent years, then applies the BRS 2% multiplier (or High-3 2.5%) against the high-36 average basic pay.

A reserve Marine with 3,000 retirement points (a reasonable career total) converts those points to 8.33 equivalent years. At the BRS rate: 2% × 8.33 × high-36 = 16.67% of high-36 per month. This is substantially lower than an active-duty retiree’s pension because the reserve career accumulates fewer points per year than full-time active service.

Collection age. The standard collection age is 60. However, reserve Marines can reduce that age by 90 days for every 90 consecutive days of active duty under qualifying Title 10 orders, down to a minimum of age 50. A reserve Marine with significant deployment history can collect significantly earlier than age 60.

TSP under reserve retirement. Reserve contributions to TSP come from drill pay and active-duty pay during activations. The BRS matching schedule applies in the same way as active duty: matching begins at the third year of service. Drill pay amounts are lower than active-duty base pay, so TSP contributions and government matching are proportionally smaller for reserve Marines who are not frequently activated.

What a 20-year retirement income looks like

For an active-duty Marine retiring at 20 years in 2026, a realistic picture:

An E-8 Master Sergeant who retires at 20 years:

• Pension (40% of high-36 ~$6,995): approximately $2,798 per month from day one
• TSP balance after 20 years of consistent 5% contributions with government matching: this grows based on investment returns, but even conservative projections suggest a balance that can support several hundred dollars per month in additional income in retirement
• Annual pension income: approximately $33,578 per year in 2026 dollars

An O-5 Lieutenant Colonel retiring at 20 years:

• O-5 at 20 years earns $12,032.70 in monthly base pay
• Pension (40% of ~$11,500 high-36): approximately $4,600 per month
• Annual pension income: approximately $55,200 per year in 2026 dollars

These pensions are for life, indexed over time, and paid without any investment management required. They represent a significant financial foundation. Combined with TSP savings, most 20-year retirees are in a stronger financial position at retirement age than comparable civilians without defined benefit pensions.

The practical planning lesson is that every year of service above 20 adds another 2% to the pension multiplier. A Marine who retires at 22 years receives 44% of high-36 instead of 40%. At 24 years, it is 48%. Staying past 20 years increases monthly pension income for the rest of the retiree’s life.
