Military retirement is unlike any other pension system in the United States. The benefits are substantial — a lifetime pension beginning immediately at separation, regardless of age — but they’re also complex. The right retirement plan, the right separation date, and the right combination of military and civilian retirement savings can make a six-figure difference in lifetime income.
Here’s how to understand your military retirement benefit and use a calculator correctly.

Which Military Retirement Plan Are You Under?
Your retirement plan depends on when you entered service:
- Final Pay: entered before September 8, 1980. Pension based on final month’s base pay.
- High-36: entered September 8, 1980 – July 31, 1986. Pension based on average of highest 36 months of base pay.
- Redux (CSRB): entered August 1, 1986 – December 31, 2017, and chose to receive a $30,000 Career Status Bonus at 15 years. Lower multiplier, reduced COLA. Widely considered a poor deal — most who were eligible chose to remain in High-36.
- Blended Retirement System (BRS): mandatory for those who entered on or after January 1, 2018. Optional for those serving as of December 31, 2017 who opted in during 2018. Lower pension multiplier (2.0% vs. 2.5%), but includes TSP contributions and government match.
How Military Retirement Pay Is Calculated (High-36 and Final Pay)
For most currently serving members not under BRS:
Monthly Retirement Pay = 2.5% × Years of Active Service × High-36 Average Basic Pay
Key points:
- Minimum 20 years of active service required to qualify for retirement pay
- Maximum multiplier caps at 75% (30 years × 2.5%)
- The High-36 average is your average basic pay over the 36 highest consecutive months — typically your final 3 years
- COLA adjustments are applied annually and are full CPI-based for High-36 and Final Pay plans
Example: E-7 retiring at 20 years, High-36 average base pay $5,200/month:
2.5% × 20 × $5,200 = $2,600/month. At 24 years: $3,120/month. At 30 years: $3,900/month.
Blended Retirement System (BRS) — Key Differences
BRS reduces the defined benefit pension multiplier from 2.5% to 2.0%, but adds:
- Government contribution of 1% of basic pay to TSP automatically
- Government match of up to 4% of basic pay on TSP contributions (vests at 2 years)
- Continuation Pay bonus at 12 years (2.5–13× monthly basic pay depending on branch and needs)
BRS favors service members who separate before 20 years — they’ll have TSP savings where the legacy system gives nothing. For those who serve 20+ years, the legacy High-36 plan generally produces higher lifetime retirement income if both pension and TSP are modeled.

How to Use the Military Retirement Calculator Accurately
The official military retirement calculator is available at myPay (mypay.dfas.mil) for active members. Key inputs:
- Retirement plan (High-36, Final Pay, BRS)
- Years and months of service at planned retirement date
- Current pay grade and time in grade
- Projected base pay at retirement (factor in expected promotions)
Third-party calculators — Military.com’s retirement calculator is widely used — can be helpful for modeling scenarios, but always cross-reference with your actual leave and earnings statements for precise inputs.
💡 Model 20 vs. 24 vs. 30 years: The pension increase per additional year of service is substantial. Model each scenario alongside civilian employment projections — the right answer depends on your branch, career specialty, and second-career opportunities.
VA Disability Compensation and Concurrent Receipt
VA disability compensation and military retirement pay are separate — but how they interact depends on your disability rating:
- Concurrent Retirement and Disability Pay (CRDP): allows retirees with 50%+ VA disability rating to receive both full retirement pay and full VA disability compensation concurrently. CRDP phases in based on years of service.
- Combat-Related Special Compensation (CRSC): provides tax-free compensation for retirees with combat-related disabilities, replacing the offset that previously applied.
If you have a VA rating and weren’t previously receiving both, review CRDP and CRSC eligibility — this is a significant source of additional income for many veterans who don’t realize they qualify.
TRICARE and Non-Pay Benefits
Military retirement isn’t just about the monthly check. The non-pay benefits are substantial and often undervalued in financial planning:
- TRICARE — comprehensive health coverage at minimal cost. TRICARE Prime is typically $300–$600/year for a family. Compared to civilian employer-sponsored health insurance costs, this alone can be worth $10,000+ per year in equivalent value.
- Commissary and Exchange access — tax-free shopping at below-market prices
- Space-available travel
- Morale, Welfare & Recreation (MWR) facilities
Factor these into your total retirement compensation comparison — they’re real economic value that doesn’t appear on your monthly LES.
Frequently Asked Questions
Q: Is military retirement pay taxable?
Military retirement pay is taxable at the federal level as ordinary income. However, VA disability compensation is completely tax-free. State taxation varies — many states exempt some or all military retirement pay from state income tax. Check your state’s rules.
Q: Can I receive both military retirement pay and Social Security?
Yes — military retirees pay into Social Security and earn full benefits. Unlike some state pension systems, military service is covered employment for Social Security purposes and the WEP does not apply to military retirement pay.
