The High-3 military retirement system pays a lifetime monthly pension equal to 2.5% of your highest 36 months of basic pay, multiplied by your years of service. Twenty years of active duty produces a pension worth 50% of that three-year average, and each additional year adds another 2.5 percentage points. High-3 covers most service members who first entered the uniformed services between September 8, 1980, and December 31, 2017, which means it is the retirement plan for the majority of current retirees and a large share of those still in uniform.
Who Is Actually in the High-3 System
Your retirement plan is set by your Date of Initial Entry into Military Service, or DIEMS. That date is fixed the first time you enter any branch of the uniformed services and it never changes, even if you switch services or have a break in service.1Military Compensation and Financial Readiness. Retirement
Two groups fall under High-3:
- If your DIEMS is between September 8, 1980, and July 31, 1986, you are automatically in High-3 with no option to switch.
- If your DIEMS is between August 1, 1986, and December 31, 2017, you default to High-3 unless you took one of two off-ramps: the Career Status Bonus under REDUX (that election closed December 31, 2017) or the Blended Retirement System during the 2018 opt-in window, which was open only to members with fewer than 12 years of service at the end of 2017.1Military Compensation and Financial Readiness. Retirement
If you never made either election, you stayed in High-3 by default. Anyone whose DIEMS is January 1, 2018, or later is in the Blended Retirement System and cannot use High-3.
How the 36-Month Average Is Built
The calculation starts by identifying the 36 months in your career where you earned the highest basic pay. Basic pay is the taxable salary on your Leave and Earnings Statement. It does not include BAH, BAS, hazardous duty pay, flight pay, sea pay, or any other special or incentive pay.2Defense Finance and Accounting Service. Estimate Your Retirement Pay Only the base salary set by the annual military pay tables counts.
For most people, the highest 36 months are the final three years of service, because basic pay rises with promotions and longevity. The calculation looks at your entire pay history, though. If you held a higher rank earlier and later reverted to a lower grade, those earlier higher-pay months can factor in.
One trap for officers: you generally must serve at least three years in your final grade (or two with a Secretary of Defense waiver) to retire at that grade. Fall short and you retire at the next lower grade, which drops the basic pay used in your High-3 average.
Once the 36 highest-pay months are identified, DFAS adds them up and divides by 36. That number is your retired pay base, and everything else flows from it.
The Pension Formula
Active duty members need at least 20 years of service to qualify for non-disability retirement.3Military Compensation and Financial Readiness. Active Duty Retirement The pension is calculated by multiplying the High-3 average by 2.5% for each year of creditable service.4Office of the Law Revision Counsel. 10 USC 1409 – Retired Pay Multiplier
Monthly retired pay = High-3 average × (years of service × 2.5%)
At common career lengths, that works out to:
- 20 years: 50% of your High-3 average
- 24 years: 60%
- 26 years: 65%
- 30 years: 75%
In real dollars, an E-7 with over 20 years earns roughly $6,246 per month in 2026 basic pay. If that rate held steady across the final 36 months, the pension would be about $3,123 per month. An O-5 at the same point earns about $12,033 monthly, translating to a pension near $6,017. Actual pay rises slightly each year with longevity increases, so the real High-3 average, and the real pension, will be a bit higher than a single snapshot suggests.
Past 30 Years
There is no statutory cap on the multiplier for non-disability retirement. Thirty years produces 75%, and the 2.5% per year keeps climbing for authorized service beyond that. Forty creditable years produces a 100% multiplier.1Military Compensation and Financial Readiness. Retirement Very few people serve that long, but the math does not stop at 75%. The 75% ceiling you sometimes see mentioned applies only to disability retirement.4Office of the Law Revision Counsel. 10 USC 1409 – Retired Pay Multiplier
Medical Retirement
Service members medically retired under Chapter 61 take whichever produces more: the standard 2.5%-per-year formula, or a percentage equal to their disability rating (capped at 75%). This matters most for members forced out before 20 years, because the disability percentage can beat what years of service would produce. The High-3 average is still the pay base either way.
Guard and Reserve Members
Reserve-component members earn retirement points instead of full years of active service. DFAS converts points to years by dividing total career points by 360.2Defense Finance and Accounting Service. Estimate Your Retirement Pay A reservist with 7,200 career points has the equivalent of 20 years, producing a 50% multiplier applied to the High-3 average of the highest 36 months of basic pay.
The bigger difference is when the checks start. Reserve retirees generally cannot draw retirement pay until age 60. Qualifying active-duty service performed after January 28, 2008, in response to a contingency operation or national emergency reduces that age by 90 days for each cumulative 90-day period served.5Military Compensation and Financial Readiness. Reserve Retirement A reservist with 360 qualifying days could start drawing at 59. The reduction cannot bring the qualifying age below 50.
Annual Cost-of-Living Adjustments
High-3 pensions get an annual COLA tied to the Consumer Price Index (all items, U.S. city average) under 10 U.S.C. § 1401a.6Office of the Law Revision Counsel. 10 USC 1401a – Adjustment of Retired Pay and Retainer Pay To Reflect Changes in Consumer Price Index Each year, DFAS compares the CPI for the third quarter against the prior year’s third quarter, and the percentage increase becomes your COLA. The adjustment takes effect December 1 and appears in the January retired pay deposit.
High-3 retirees receive the full CPI increase with no reduction. That is a real advantage over REDUX, which shaves one percentage point off any annual increase above 1%. Over a 30- or 40-year retirement, full COLAs compound. A $3,000 monthly pension grows past $5,000 after two decades at a 3% average, without the retiree doing anything.
VA Disability Offset, CRDP, and CRSC
Federal law reduces your military retirement pay dollar-for-dollar by the amount of any VA disability compensation you receive. This is the VA waiver, or VA offset.7Defense Finance and Accounting Service. Understanding the VA Waiver and Retired Pay, CRDP, CRSC The total money hitting your bank account stays close to the same, and the VA portion is tax-free, but your DoD retired pay shrinks by whatever the VA pays.
Two programs can restore some or all of the lost retirement pay:
- Concurrent Retirement and Disability Pay (CRDP) restores your full retirement pay if your combined VA rating is 50% or higher, so you receive both pension and VA compensation without an offset. CRDP is automatic for eligible retirees.8Defense Finance and Accounting Service. Concurrent Military Retired Pay and VA Disability Compensation
- Combat-Related Special Compensation (CRSC) covers disabilities caused by combat, hazardous duty, conditions simulating war, or an instrumentality of war. There is no minimum rating, but the disability must be combat-related and you must have 20 or more qualifying years (or be a reserve retiree under Chapter 1223). You apply through your branch of service.
You can qualify for both, but you can only receive one at a time. DFAS pays whichever is more favorable unless you elect otherwise, and you get one chance per year to switch.7Defense Finance and Accounting Service. Understanding the VA Waiver and Retired Pay, CRDP, CRSC If your rating is below 50% and your disability is not combat-related, the dollar-for-dollar offset stays in place.
The Survivor Benefit Plan
High-3 retirement pay stops when the retiree dies. The Survivor Benefit Plan (SBP) is the main way to keep income flowing to a surviving spouse or other dependent. The surviving spouse receives 55% of the base amount the retiree chose to cover.9Military Compensation and Financial Readiness. Spouse Coverage The base can be set as low as $300 per month or as high as the full retired pay amount.
Spouse coverage costs 6.5% of the elected base amount, deducted from retired pay each month before taxes. SBP payments to the survivor track the same COLA as retired pay, so the benefit keeps pace with inflation.
Premiums do eventually stop. Once you reach age 70 and have paid premiums for at least 360 months (30 years), you are “paid up” and no more deductions come out. Coverage continues for life at no cost.9Military Compensation and Financial Readiness. Spouse Coverage Both conditions must be met, so someone who retires at 38 after 20 years hits 360 months of premiums at 68 but still pays until 70.
Divorce and the Frozen Benefit Rule
Military retirement pay can be divided in divorce under the Uniformed Services Former Spouses’ Protection Act. Since the 2017 National Defense Authorization Act, a “frozen benefit rule” applies. The share subject to division is based on the member’s rank and years of service as of the date of divorce, not the eventual retirement date. If you are an E-7 with 15 years when the divorce is finalized but retire as an E-9 with 26 years, the former spouse’s share is calculated on what an E-7 at 15 years would have received.
The only adjustment allowed between the divorce and retirement is the annual COLA. DFAS pays the former spouse directly once it receives a qualifying court order. The rule prevents a former spouse from benefiting from promotions and additional service earned entirely after the marriage ended, but it also creates complications if the court order does not clearly state the member’s pay grade and years of service at the time of divorce.
How High-3 Retirement Pay Is Taxed
Military retirement pay based on length of service is taxable as ordinary federal income. DFAS withholds federal income tax each month, and you adjust withholding by submitting a new W-4 through myPay.10The Official Army Benefits Website. Federal Taxes on Veterans Disability or Military Retirement Pensions Military retirement pay is not earned income for Social Security purposes, so no FICA is deducted.
State treatment varies. More than 30 states now fully exempt military retirement pay from state income tax, and several others offer partial exemptions. On a $3,000-per-month pension, a full exemption is worth thousands a year, so the state you settle in matters.
VA disability compensation is tax-free at both the federal and state level. That is why the VA offset, frustrating on paper, often raises after-tax income: the same dollars shift from a taxable source to a nontaxable one.
