Military Retirement Pay Calculator: How Your Monthly Check Is Calculated
Military retirement pay is calculated using one of three formulas depending on your retirement system. Here is how High-3, BRS, and REDUX work, with step-by-step examples at common pay grades.
- Military retirement pay is calculated as: years of qualifying service multiplied by the applicable percentage multiplier, applied to the average of the highest 36 months of basic pay (High-36). The result is your gross monthly retired pay.
- The High-3 (legacy) multiplier is 2.5 percent per year of service. At 20 years, the formula produces 50 percent of the High-36 average. At 30 years, it produces 75 percent.
- The BRS multiplier is 2.0 percent per year. At 20 years the pension is 40 percent of the High-36 average, 10 points below High-3, offset partially by DoD TSP matching accumulated during service.
- REDUX reduces the High-3 multiplier by 1 percent per year of service below 30, in exchange for a $30,000 Career Status Bonus at 15 years. At 20 years, REDUX pays 40 percent instead of 50 percent.
- Military retired pay adjusts annually by the Consumer Price Index COLA each December 1 under 10 U.S.C. § 1401b. REDUX uses a reduced COLA of CPI minus 1 percent until age 62.
Quick Answer: Military retirement pay equals years of service times the applicable multiplier (2.5% for High-3, 2.0% for BRS), applied to the average of your highest 36 months of basic pay. At 20 years under High-3: 50 percent of average basic pay. BRS: 40 percent. REDUX: 40 percent plus a $30,000 bonus paid at year 15.
Does this calculation apply to your situation?
- Are you currently serving in the U.S. military and planning for retirement?
- Yes: Identify your retirement system (High-3, BRS, or REDUX) before applying the formulas below
- No: If you are already retired, verify your actual payment on your DFAS statement. If it differs from the formula result, contact DFAS to request a payment audit
- Do you know which retirement system you are enrolled in?
- Yes: Jump to the section for your system below
- No: Members who entered service before January 1, 2018 are generally under High-3 unless they opted into BRS during the 2018 window. Members who entered on or after January 1, 2018 are under BRS. Contact your branch personnel office to confirm
- Do you receive VA disability compensation in addition to retired pay?
- Yes: Your total income picture includes retired pay plus VA compensation; CRDP or CRSC may affect how much of the retired pay you retain. See the concurrent receipt article below
This is a general reference guide. Consult DFAS and a certified financial planner with military expertise for calculations using your actual pay history.
The High-36 Base: What “Average of Highest 36 Months” Means
All three military retirement formulas apply the multiplier to the same base: the average of the 36 consecutive months of highest basic pay in the member’s career. This is defined at 10 U.S.C. § 1407.
Basic pay rates are published annually in the National Defense Authorization Act and are determined by pay grade (E-1 through O-10, W-1 through W-5) and years of service. Basic pay does not include housing allowance, subsistence allowance, special pays, or bonuses.
For most members, the High-36 average is the average of the final three years of service, when pay is highest. Members who were promoted and subsequently reduced in grade, or who had periods of higher pay that ended before retirement, may have a High-36 average from an earlier period.
To estimate your High-36 average: Find the monthly basic pay for your pay grade and years of service for the three years before your planned retirement date using the current DoD pay tables. Average the 36 monthly figures. This is your base.
The High-3 Formula
Formula: Years of qualifying service x 2.5% x High-36 average = monthly retired pay
At 20 years: 20 x 2.5% = 50% of High-36 average
At 22 years: 22 x 2.5% = 55%
At 26 years: 26 x 2.5% = 65%
At 30 years: 30 x 2.5% = 75% (the cap most members target for officer careers)
Example: An E-8 with 20 years whose average basic pay over the highest 36 months was $5,200 per month:
- 20 x 2.5% = 50%
- 50% x $5,200 = $2,600 per month
Example: An O-5 with 22 years whose High-36 average was $9,800 per month:
- 22 x 2.5% = 55%
- 55% x $9,800 = $5,390 per month
High-3 is the baseline. Members under High-3 who did not elect REDUX at the 15-year mark receive this calculation automatically. DFAS applies the formula using official pay records, but working the math yourself provides a verification point.
The BRS Formula
Formula: Years of qualifying service x 2.0% x High-36 average = monthly retired pay (pension component)
At 20 years: 20 x 2.0% = 40% of High-36 average
At 26 years: 26 x 2.0% = 52%
At 30 years: 30 x 2.0% = 60%
Example using the same E-8 with a $5,200 High-36 average:
- 20 x 2.0% = 40%
- 40% x $5,200 = $2,080 per month
The BRS pension produces $520 per month less than High-3 at the same pay level and years of service. The offset is TSP assets accumulated through DoD matching over the career.
TSP component: BRS members should calculate their expected TSP balance at retirement and model the income it can generate. A $100,000 TSP balance at a 4 percent withdrawal rate produces $333 per month. A $200,000 balance produces $667 per month. At higher balances and longer investment timelines, TSP income can approach or exceed the pension gap.
BRS total retirement income = pension + TSP income from accumulated assets. The TSP component is variable and depends on contribution rate, investment choices, and years of compounding.
The REDUX Formula
REDUX is a variant of the High-3 legacy system available only to members who entered service before January 1, 2018 and elected the Career Status Bonus at the 15-year mark. REDUX is not available under BRS.
Formula at retirement: The REDUX multiplier is reduced by 1 percentage point for each year of service below 30.
At 20 years: High-3 would pay 50%. REDUX pays 50% minus (30 - 20) x 1% = 50% - 10% = 40%. At 24 years: High-3 would pay 60%. REDUX pays 60% - 6% = 54%. At 30 years: Both formulas produce 75%. The multiplier penalty disappears at 30 years.
Example using the same E-8 with a $5,200 High-36 average, retiring at 20 years:
- REDUX multiplier: 40% (same as BRS at 20 years by coincidence of the math)
- 40% x $5,200 = $2,080 per month
The REDUX member received a $30,000 Career Status Bonus at the 15-year mark, which must be weighed against the lifetime pension reduction and COLA penalty described below.
REDUX COLA penalty: REDUX retired pay adjusts by CPI-W minus 1 percentage point per year until the member reaches age 62. In a year with 2.5 percent inflation, a High-3 or BRS member receives a 2.5 percent COLA while a REDUX member receives 1.5 percent. This compounding difference reduces purchasing power significantly over a 20 to 30-year retirement.
At age 62, REDUX members receive a one-time catch-up adjustment restoring their pension to what it would have been under High-3 at that point. After age 62, the COLA returns to full CPI-W.
COLA and the Annual Adjustment
Military retired pay adjusts each December 1 under 10 U.S.C. § 1401b to match the Social Security Administration COLA announced in October. The 2026 adjustment was 2.5 percent.
For High-3 and BRS members, the full CPI-W rate applies annually. For REDUX members, the adjustment is CPI-W minus 1 percentage point, with a floor of 0 percent (retired pay does not decrease). The COLA compounds over time, so the difference between full and reduced COLA grows each year.
A 2026 retiree earning $2,000 per month under High-3 will see their pay adjust by 2.5 percent ($50) per year of full inflation. A REDUX retiree at the same amount receiving only 1.5 percent COLA ($30) falls $20 per month behind in the first year alone. Over 15 years before age 62 catch-up, the cumulative shortfall is substantial.
Survivor Benefit Plan
The Survivor Benefit Plan (SBP) provides a continuing annuity to a surviving spouse or dependent after the retiree’s death. The default SBP coverage at retirement is the full benefit, which pays the surviving spouse 55 percent of the member’s gross retired pay.
SBP is not free. The cost is 6.5 percent of gross retired pay. For a retiree receiving $2,500 per month, SBP costs $162.50 per month. The premium is deducted from retired pay before distribution.
At the 30-year mark, SBP premiums become paid-up with no further deduction, but coverage continues. Members can elect reduced coverage or decline SBP entirely at retirement with a one-time irrevocable election. Declining SBP waives the survivor benefit permanently.
SBP premiums are tax-deductible, and SBP annuity payments to the survivor are taxable income to the recipient.
What the Calculation Does Not Include
The retired pay formula produces the base pension only. Total military retiree income typically includes additional components:
VA disability compensation, which is tax-free and separate from the pension. For retirees with a combined VA rating of 50 percent or higher and 20 qualifying years, CRDP eliminates the dollar-for-dollar offset that previously reduced pension income.
TSP distributions, which begin penalty-free at age 59.5 (or at separation after age 55 under certain rules).
Social Security, for which military service counts as credited quarters.
These are separate income streams that do not affect the retired pay formula itself but are essential to any complete retirement income analysis.

How is military retirement pay calculated?
Military retirement pay equals years of qualifying service multiplied by the percentage multiplier, applied to the average of your highest 36 consecutive months of basic pay. High-3 uses a 2.5 percent multiplier; BRS uses 2.0 percent; REDUX uses a reduced multiplier (2.5% minus 1% per year below 30 years of service). The calculation uses the High-36 average, not current pay at the time of retirement.
What is the High-36 average and how is it calculated?
The High-36 average is the arithmetic mean of your 36 highest consecutive months of basic pay, as defined at 10 U.S.C. § 1407. For most service members, this is the last three years of service when pay is at its peak. If you held a higher rank and were later reduced in grade, VA recalculates using the 36 highest months, which may not be the most recent. DFAS calculates this automatically from your pay history.
What pay grade and years of service produce the highest retirement?
Retirement pay is maximized by achieving the highest possible pay grade before retirement and serving as many years as possible under 40 years, after which the multiplier caps at 100 percent of average basic pay. An O-6 retiring at 26 years earns significantly more than an E-7 at 20 years, both in absolute terms and as a percent of final pay, because both the High-36 base and the multiplier are higher.
Is military retirement pay taxable?
Yes. Military retirement pay is taxable as ordinary income under federal law. VA disability compensation is not taxable under 26 U.S.C. § 104. CRSC is not taxable. CRDP is taxable. For retirees receiving both retirement pay and VA disability, the taxable and non-taxable portions depend on which concurrent receipt program applies. State tax treatment varies; many states exempt military retired pay fully or partially.
When does military retirement pay start and how is it paid?
Military retirement pay begins the month after the last month of active duty service. DFAS pays on the first business day of each month for the prior month. The first payment appears one to two months after separation, depending on DFAS processing time. Retirees who also receive VA disability compensation receive that payment separately from VA on a different schedule.
Does military retirement pay include a cost-of-living adjustment?
Yes. Military retired pay adjusts annually by the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) under 10 U.S.C. § 1401b, matching the VA disability COLA under 38 U.S.C. § 5312. For 2026, both the military retirement COLA and VA disability COLA were 2.5 percent. REDUX members receive the CPI-W rate minus 1 percentage point until age 62, at which point they receive a one-time catch-up adjustment.
