What is the Military Retirement Calculator?
The Military Retirement Calculator determines your monthly pension based on retirement system (High-3, BRS, or REDUX), years of service, and base pay. Military retirement is one of the most valuable benefits available – a 20-year E-7 receives approximately $3,100/month for life starting immediately upon retirement, with annual COLA increases. Unlike civilian 401(k)s where you wait until age 59½ to access funds penalty-free, military retirement pays immediately, even if you retire at age 38.
The Three Retirement Systems
High-3 (Final Pay) applies to service members who entered before September 8, 1980. This system calculates retirement pay as 2.5% × years of service × average of highest 36 months of base pay. A 20-year retiree receives 50% of High-3 average base pay, a 30-year retiree receives 75%. This is the most generous system for those who serve 20+ years.
BRS (Blended Retirement System) applies to those who entered after January 1, 2018, or opted in during the 2018 choice period. BRS provides 2% × years of service × High-3 base pay, plus TSP matching contributions and a continuation pay bonus at 12 years. A 20-year BRS retiree receives 40% of High-3 pay instead of 50%, but the TSP matching throughout their career often makes up the difference for disciplined savers.
REDUX was a temporary system from 1986-2016 offering a $30,000 Career Status Bonus at 15 years in exchange for reduced retirement multiplier (2.0% instead of 2.5%). Very few service members chose REDUX as the long-term pension reduction outweighed the upfront bonus. REDUX retirement is 2% × years of service × High-3, then reduced further for retiring before 30 years.
Example: E-7 Retiring After 20 Years
Highest 36 months average base pay: $6,200 (averaged across 2026 E-7 pay brackets for YOS 18, 19, 20)
High-3 Retirement: 50% × $6,200 = $3,100/month gross, approximately $2,635/month after taxes
Annual Value: $37,200 gross, $31,620 net
Lifetime Value (age 40 to 80): $1,488,000 gross, assuming 3% annual COLA increases
The 20-Year Decision
The difference between separating at 19 years versus staying to 20 is approximately $1.2-1.8 million in lifetime pension value for enlisted members, more for officers. This is why service members often endure difficult final years to reach 20 – the financial benefit is massive. However, serving unhappily from year 16-20 just for retirement can damage mental health and family relationships. Run the numbers, but also consider quality of life.
Medical Retirement (Chapter 61): When the 20-Year Rule Doesn't Apply
Medical retirement under 10 USC Chapter 61 is the path for service members found unfit for continued service by a Medical Evaluation Board (MEB) and Physical Evaluation Board (PEB). Unlike standard retirement, there's no minimum years-of-service requirement — a soldier injured at year 4 can be medically retired with full benefits, including TRICARE for life, commissary/exchange access, and a monthly pension.
The Medical Retirement Formula
Medical retirement pay uses the better of two calculations: max(years × 2.5%, DoD disability rating), multiplied by your high-3 average base pay, capped at 75%. The DoD assigns its own disability rating during the MEB/PEB process — separate from your VA rating, often different in percentage. A 30% DoD rating is the minimum for permanent medical retirement (PDRL); below that, members are typically separated with severance pay rather than retired.
Example: An E-6 separated at 12 years of service with a 70% DoD disability rating. Length-of-service path: 12 × 2.5% = 30%. DoD disability path: 70%. The formula takes the higher value, so this retiree receives 70% × high-3 pay. At an E-6 high-3 of $4,800, that's $3,360/month for life — significantly more than the $1,440/month they'd get from the length-of-service calculation alone.
Key Differences from Standard Retirement — and the VA Offset Reality
The hard truth most calculators get wrong: Chapter 61 retirees are subject to the VA offset by default. Your pension is reduced dollar-for-dollar by your VA disability compensation. So a Ch61 retiree with a $2,000 pension and $1,500 VA disability typically receives $500 in pension + $1,500 in VA disability = $2,000 total — not the $3,500 stack that many online calculators imply.
Two narrow paths break the offset:
(1) Concurrent Retirement and Disability Pay (CRDP) restores full pension, but requires 20+ years of qualifying service. Chapter 61 retirees with fewer than 20 YOS are explicitly excluded by statute. Even Chapter 61 retirees who reach 20+ YOS get CRDP only for the length-of-service portion of pension; the additional amount attributable to disability remains offset. There is currently legislation pending (the Major Richard Star Act) to extend CRDP to combat-related Chapter 61 retirees regardless of YOS, but it has not passed as of 2026.
(2) Combat-Related Special Compensation (CRSC) is available only for disabilities deemed combat-related by your service branch's CRSC board. CRSC restores offset amounts for those qualifying conditions, paid as a separate check from your branch rather than as restored pension. CRSC and CRDP are mutually exclusive — eligible retirees must elect one annually during open season.
The data is sobering: Of approximately 575,000 Chapter 61 retirees nationally, only about 52,000 (~9%) receive CRSC. The remaining 91% either don't have combat-related disabilities or have less than 20 YOS, leaving them subject to the full VA offset. This calculator shows your gross Chapter 61 retired pay only — to see your true take-home after the offset, use the Retirement Income Summary, which includes CRDP and CRSC toggles.
Two additional considerations: Potential tax-free portion under IRC §104(a)(4) — the share of pension attributable to your disability may be excluded from federal income tax depending on your service date and condition origin. TDRL vs PDRL — Temporary Disability Retired List members are reviewed every 18 months for up to 5 years before transitioning to Permanent Disability Retired List or being recalled/separated. Pension math is identical between TDRL and PDRL; only the review schedule differs.
The financial reality of medical retirement is harder than the marketing implies. A 70% DoD-rated E-7 at 12 years with no combat connection sees gross pension of ~$3,400/month — but receives only the larger of (pension OR VA disability), not both. Their actual take-home is closer to the VA disability amount (~$1,700-2,200/month depending on dependents). StoryLine VA helps medical retirees document their conditions for VA claim filing — and combat-related conditions for the separate CRSC application.
Can I receive military retirement and VA disability?
It depends on your retirement type. For 20-year (longevity) retirees under High-3, BRS, or REDUX: under CRDP (Concurrent Retirement and Disability Pay), retirees with 20+ years and 50%+ VA rating receive both full retirement and full VA disability without offset. Those with combat-related disabilities can also pursue CRSC (Combat-Related Special Compensation) — but cannot receive both CRSC and CRDP simultaneously. For Chapter 61 medical retirees: the default is that VA disability OFFSETS your pension dollar-for-dollar. Concurrent receipt requires either (a) 20+ years of qualifying service for CRDP, OR (b) approved combat-related disabilities for CRSC. Roughly 91% of Chapter 61 retirees do not qualify for concurrent receipt and ARE subject to the full VA offset. Use the Retirement Income Summary with the medical-retirement toggles to see your true post-offset take-home.
How does SBP (Survivor Benefit Plan) work?
SBP allows retirees to pay a premium (6.5% of retirement pay) to provide 55% of their retirement income to a surviving spouse if the retiree dies. Without SBP, retirement pay stops at death and the spouse receives nothing. With SBP, a spouse continues receiving 55% of the pension for life. For young retirees (retiring at 38-42), SBP is often valuable since spouses might receive benefits for 30-40+ years. For older retirees or those with substantial other assets, SBP might not be worth the cost. Run the math with the Survivor Benefits Calculator.
Retirement Pay vs. Civilian Retirement
Military retirement is fundamentally different from civilian retirement. You receive it immediately upon retiring (no waiting until 60-65), it's guaranteed for life, it includes annual COLA increases, and it's backed by the federal government (no bankruptcy risk like corporate pensions). A 40-year-old E-7 retiree receiving $2,950/month will receive $3,600+/month by age 60 due to COLA increases. The present value of this pension is often $800,000 to $1.5 million depending on life expectancy and discount rates.
This is why financial advisors tell military members to "stay to 20 if at all possible" – you're walking away from an enormously valuable pension if you separate at 15-19 years. Even if you're miserable in your final years, the financial benefit of that pension might justify toughing it out. However, mental health matters too. If staying is destroying your wellbeing or family, no pension is worth that cost.
