Army Retirement Pay Estimator
Estimate your monthly retired pay for active-duty Army service using either Legacy High-3 or Blended Retirement System (BRS).
How this army retirement calculator works
This calculator gives you a practical estimate of Army retirement income based on the two most common active-duty formulas:
- Legacy High-3: 2.5% multiplier per year of service
- Blended Retirement System (BRS): 2.0% multiplier per year of service
Your monthly pension estimate starts with your High-36 average monthly basic pay, then applies the retirement multiplier. From there, the tool can estimate deductions for taxes and SBP and show a future value using a COLA assumption.
Core formula used
Legacy High-3
Retired Pay = High-36 Monthly Basic Pay × (Years of Service × 2.5%)
Blended Retirement System (BRS)
Retired Pay = High-36 Monthly Basic Pay × (Years of Service × 2.0%)
For example, if your High-36 is $7,000 and you retire at 20 years:
- Legacy: 7,000 × 50% = $3,500/month
- BRS: 7,000 × 40% = $2,800/month
Understanding each input
1) Years of service
This is your creditable active-duty service at retirement. The multiplier increases directly with years served.
2) High-36 average pay
This is not your final paycheck; it is the average of your highest 36 months of basic pay. Allowances like BAH/BAS are usually not part of retired pay base.
3) VA disability compensation
VA compensation is shown as a separate monthly amount so you can estimate total cash flow. Tax treatment varies, and concurrent receipt rules can apply depending on your situation.
4) SBP premium
If elected, SBP premiums reduce take-home income today in exchange for potential survivor income protection. This tool treats SBP as a percentage deduction from gross retired pay.
5) Taxes
Military retired pay is generally taxable at the federal level (with exceptions based on circumstances), and state treatment differs widely. This calculator uses your estimated rates for planning only.
6) COLA projection
Annual cost-of-living adjustments can significantly increase nominal pension income over time. The projection here compounds your initial gross pension by your COLA rate.
What this calculator includes and excludes
Included

- Monthly and annual gross retired pay estimate
- Optional SBP and tax impact
- Optional VA compensation add-on for a total monthly estimate
- Forward projection with COLA
Not included
- TSP balance and withdrawals
- BRS continuation pay history
- Special compensation programs and offsets
- Reserve/Guard points-based non-regular retirement calculation
- Detailed IRS/state-specific tax rules
Active-duty vs Reserve Component retirement
This page is designed mainly for active-duty pension estimation. Army National Guard and Army Reserve retirements are typically calculated from retirement points and usually begin at eligibility age (with some reduced-age exceptions). If you are Reserve Component, use a points-to-equivalent-service calculator for a more accurate estimate.
Tips to increase retirement readiness
- Know your system early: Legacy and BRS create different pension outcomes.
- Track your LES and records: Verify pay history and service credit well before retirement.
- Model taxes conservatively: Overestimate tax drag so your plan has margin.
- Plan healthcare and insurance costs: TRICARE options and family needs change over time.
- Pair pension with TSP strategy: Pension + disciplined drawdown creates resilient cash flow.
Example scenario
Suppose a soldier retires at 22 years with a High-36 of $8,200 under Legacy. Multiplier is 55%. Gross pension estimate is $4,510/month. If SBP is 6.5% and combined taxes are 15%, take-home will be lower, but COLA over the next decade can still materially increase gross income.
Frequently asked questions
Is this an official Army finance calculator?
No. This is an educational planning tool. Use official DFAS resources and your installation retirement services office for final numbers.
Does this replace a full retirement plan?
No. A complete retirement plan should include TSP, Social Security timing, debt strategy, healthcare, survivor needs, and inflation stress testing.
Why does my estimate differ from another tool?
Different tools may assume different tax treatment, SBP handling, COLA values, and service-credit details. Always compare assumptions line by line.
Bottom line: an army retirement calculator is most useful when you run multiple scenarios—base case, conservative case, and optimistic case—so your retirement decisions are based on a range, not a single number.
