How Much Is Military Retirement Pay at 20 Years in 2026? (E-7 and O-5 Examples)
Quick answer
At 20 years of active service, military retired pay is 50% of your highest-36-month average basic pay under High-3, or 40% under the Blended Retirement System (BRS). On the 2026 pay table an E-7 over 20 years earns $6,245.70 a month; the 36-month average is about $6,058, so the pension is about $3,029 a month (High-3) or $2,423 (BRS), before tax. An O-5 gets about $5,836 or $4,669. The check rises with prices every December for life.
The formula, and the trap most calculators fall into
Every regular military retirement uses the same two-part formula:
Monthly retired pay = retired pay base × multiplier
- Retired pay base is the average of your highest 36 months of basic pay (the "high-36" or "high-3"). Basic pay only. Housing (BAH) and food (BAS) allowances are never in the formula, which is why the check looks smaller than your take-home pay.
- Multiplier is 2.5% per year of service under High-3 (entry before January 1, 2018, no opt-in) and 2.0% per year under the BRS (entry on or after January 1, 2018, or opted in during 2018). At 20 years that is 50% or 40%. At 30 years, 75% or 60%.
The trap: many online calculators multiply the "over 20" pay cell by 50% and call it a day. Your highest 36 months include two years at the previous longevity step and two Januarys before the last pay raise, so the average sits a few percent below the final month. The military retirement calculator uses 97% of the final cell as the default and lets you change it; DFAS will compute the exact figure from your pay history when you retire.
2026 pension at 20 years, grade by grade
All figures use the DFAS basic pay table effective January 1, 2026 (a 3.8% raise), the "over 20" column, a 97% high-36 share, and the federal tax a single filer would owe on the pension alone after the $16,100 standard deduction.
| Grade at retirement | 2026 basic pay, over 20 | High-3 pension (50%) | BRS pension (40%) | High-3 after federal tax |
|---|---|---|---|---|
| E-5 | $4,421.70 | $2,145 | $1,716 | $2,064 |
| E-6 | $5,267.70 | $2,555 | $2,044 | $2,430 |
| E-7 | $6,245.70 | $3,029 | $2,423 | $2,847 |
| E-8 | $6,995.40 | $3,393 | $2,714 | $3,167 |
| E-9 | $8,105.10 | $3,931 | $3,145 | $3,641 |
| O-3 | $9,004.20 | $4,367 | $3,494 | $4,025 |
| O-4 | $10,509.90 | $5,097 | $4,078 | $4,667 |
| O-5 | $12,032.70 | $5,836 | $4,669 | $5,288 |
| O-6 | $13,751.10 | $6,669 | $5,335 | $5,938 |
Two things stand out. First, the BRS pension is exactly 20% smaller at every grade, because 2.0 is 80% of 2.5. The BRS makes that up with the Thrift Savings Plan (TSP) match, and only if you use it. Second, federal tax takes far less than people fear: a $3,029 E-7 pension loses about $182 a month, because the standard deduction shelters the first $16,100 a year and the rest sits in the 10% and 12% brackets. Many states take nothing at all.
E-7 at 20 years: High-3 versus BRS, worked through
Take an E-7 with 12 years of service, age 38, planning to retire at 20 in 2034.
Under High-3. Pay base $6,245.70 × 97% = $6,058. Multiplier 20 × 2.5% = 50%. Pension $3,029 a month in today's dollars. If pay tables rise 2.8% a year, the first check in 2034 is about $3,778 in that year's dollars, and it then rises with the Consumer Price Index every December. Paid from age 46 to 85, that is 39 years and about $1.42 million in today's dollars. After federal tax as sole income, about $2,847 a month.
Under the BRS, with a $40,000 TSP and 5% of pay going in. Pension 40% of $6,058 = $2,423 a month, which is $606 less, every month, for life. The TSP is the other half of the deal. The E-7 puts in 5% and the government adds 5% (1% automatic plus a 4% match) on basic pay that climbs from $5,591.70 to $6,245.70 over eight years. At 5% growth after inflation, the balance reaches about $126,200 at 20 years. Drawn at 4% a year, that is $421 a month, for $2,844 combined: $185 a month short of the High-3 check, with a $126,000 account the High-3 retiree does not have. Raise the TSP to 10% of pay and the balance at 20 years is about $159,800, adding roughly $112 a month at the same draw. The military TSP contribution engine shows the match math pay period by pay period.
O-5 at 20 and 24 years
Officers retire on the same formula with bigger cells. An O-5 over 20 years earns $12,032.70 in 2026, so 20 years pays about $5,836 a month under High-3 or $4,669 under the BRS.
Most O-5s who reach 20 stay longer, and the table rewards it. Over 24 years the O-5 cell is $12,394.80. A BRS O-5 who is 40 today with 16 years, $150,000 in the TSP and 5% going in, and who retires at 24:
- Pension: $12,394.80 × 97% × 48% = $5,771 a month today's dollars (about $7,198 in 2034 dollars).
- After federal tax as sole income: about $5,237 a month.
- TSP at 24 years: about $356,800, worth $1,189 a month at 4%, for $6,960 combined.
- Lifetime pension from 48 to 85: about $2.56 million in today's dollars.
The same O-5 under High-3 would draw $7,214 at 24 years, with no government TSP money.
What changes the number most
Every input in the formula is something you control, and the engine ranks them for your grade. For the E-7 above, in monthly income for life, today's dollars:
| Move | High-3 | BRS |
|---|---|---|
| Serve 2 more years (22 years, next pay step, +5 or +4 points) | +$425 a month | +$340 a month |
| One more promotion, retire as an E-8 | +$364 a month | +$291 a month |
| Put 5 points more of pay in the TSP (5% → 10%) | not available | +$33,600 balance, about +$112 a month |
| Take continuation pay at 12 years and invest it | not available | 2.5 × monthly basic pay, invested to retirement |
Years beat everything because they change both halves of the formula: the multiplier climbs 2.5 (or 2) points and the pay base steps up to the next longevity column. From 20 to 24 an E-7 goes from $3,029 to $3,840 a month under High-3; to 30 years, $5,142. For an O-5, 20 → 24 → 30 is $5,836 → $7,214 → $9,017. The promotion lever runs into the time-in-grade rule: under 10 U.S.C. 1370, an officer at O-4 or above needs three years in the new grade to retire in it (the Secretary can cut that to two), so an O-5 promoted at year 19 who wants to retire as an O-6 is looking at 22 years, not 20. Run the military retirement calculator with your own grade and years to see the ranking for you.
Inflation, tax, and two things the check does not include
Inflation. Retired pay is raised every December 1 by the change in the CPI-W. The adjustment effective December 1, 2025 was 2.8%. That is why the engine shows the pension flat in today's dollars: a $3,029 check keeps buying what $3,029 buys today, for life.
Tax. Retired pay is federal ordinary income, with no Social Security or Medicare tax withheld. State treatment ranges from fully exempt to fully taxed.
Not included: the Survivor Benefit Plan premium (6.5% of the covered amount, if you elect it), and the VA disability offset (retired pay is reduced dollar for dollar by VA compensation unless you qualify for concurrent receipt). If you expect a rating, the VA disability rating calculator shows what that check would be. Leave before 20 years and the pension is zero: under the BRS you keep your TSP plus the government's contributions once you pass two years; under High-3, only your own savings.
FAQ
Q: How much is E-7 retirement pay at 20 years in 2026?
About $3,029 a month under High-3 and $2,423 under the BRS, before tax and in today's dollars. That is 50% or 40% of a $6,058 high-36 average, which is 97% of the $6,245.70 an E-7 over 20 years earns on the 2026 table. After federal tax as sole income, the High-3 figure is about $2,847.
Q: How much is O-5 retirement pay at 20 years?
About $5,836 a month under High-3 or $4,669 under the BRS, from a 2026 over-20 cell of $12,032.70. At 24 years the figures rise to $7,214 and $5,771, because the multiplier reaches 60% or 48% and the pay cell steps up to $12,394.80.
Q: Is the BRS pension really 20% smaller?
Yes. The multiplier is 2.0% per year instead of 2.5%, so at every length of service the BRS pension is 80% of the High-3 pension. The BRS adds a 1% automatic TSP contribution plus a match of up to 4%, and a mid-career continuation pay bonus, to make up the difference. In the E-7 example a 5% contribution closes about $421 of the $606 gap at a 4% draw.
Q: Does military retirement pay increase every year?
Yes, by law. Each December 1 it rises with the CPI-W. The December 1, 2025 adjustment was 2.8%. The first adjustment after you retire can be partial, depending on the month you retire.
Q: What happens to my pension if I leave at 18 years?
Nothing is paid. An active-duty pension requires 20 years of service. At 18 years the "serve 2 more years" lever is worth the entire pension, which for an E-7 is about $3,029 a month for life under High-3.
Q: Should I take the BRS lump sum?
The lump sum pays 25% or 50% of your retired pay to age 67 as discounted cash, and cuts the monthly check to 75% or 50% until 67, then restores it. The discount rate is set by DoD each June and the cash is taxable in the year received. A lifetime check indexed to inflation is usually worth more than the discounted cash; the official BRS calculator gives your dollar figure.
