Estimate retired pay using a simplified active-duty service multiplier. Select the legacy or Blended Retirement System assumption and supply the applicable monthly basic-pay basis. This is not a military eligibility or personnel-record calculator.

Before you enter your numbers
For a High-36-style scenario, use the relevant average basic-pay amount, not take-home pay including housing and subsistence allowances. Check the retirement system that actually applies to your service record before choosing a multiplier.

- Years of service
- Retirement system
Formula and calculation method
The simplified BRS calculation uses 2% per service year; the legacy option uses 2.5%. Monthly retired pay equals the pay basis times the service multiplier. The tool caps the multiplier at 100%, a modeling restriction that can differ from special long-service rules.
Worked example
With 20 years and a 5,000 monthly pay basis, a 2% multiplier produces 40% of that basis, or 2,000 monthly. A 2.5% multiplier produces 50%, or 2,500 monthly. This compares only the pension component, not the total value of BRS benefits.
How to interpret the result
The result panel reports estimated monthly retired pay, annual retired pay and the multiplier used.
Reserve points, disability retirement, REDUX, survivor coverage, VA-related interactions, taxes and lump-sum options require separate treatment. BRS can also involve TSP contributions that are absent from this retired-pay figure. Do not infer that the higher pension number makes one complete system better.
Legacy High-3 vs Blended Retirement System
The tool uses the selected common active-duty multiplier: 2.5% per year for the legacy High-3 system and 2.0% per year for the Blended Retirement System. That percentage is applied to the monthly retired-pay base you enter.
Reserve/Guard retirement, disability retirement, REDUX/CSB and special cases require different calculations. If your service path does not match the common active-duty formula, use the result only as a rough comparison.
Compare full benefit packages, not just the multiplier
A legacy pension and BRS are not fully compared by their pension percentages. TSP balances and contributions can form another part of the retirement package. A calculation using only monthly retired pay omits those assets and any other system-specific features.
Keep the pay basis distinct from total military compensation. Housing and subsistence allowances can support your working-life budget but are not automatically included in the pension basis entered here. Compare the projected payment with a retirement budget that reflects the costs you will actually face after service.
Confirm which military retirement system applies to your service
Military retirement formulas depend on the retirement system and service history. A simplified multiplier can be useful for an active-duty pension scenario, but Reserve and Guard retirement, disability retirement, continuation pay and other provisions require additional inputs that this tool does not model.
Use current official pay and service records when building a scenario. Avoid using an assumed future rank or pay level as if it were guaranteed; run a conservative case alongside any promotion-based estimate.
Use The Result In The Next Calculation
Use the military pension estimate as one income stream in a complete retirement plan. Verify the applicable retirement system and service record first, then model personal savings separately so pension income is not accidentally counted as an investment balance.

Military Retirement Calculator FAQs
Can a Reserve or Guard member use years of service alone?+
No. Reserve retired pay commonly requires retirement-point and eligibility information that this simplified active-duty model does not collect.
Where can I check the assumptions behind this result?+
Check the formula and limitations sections on the Military Retirement Calculator page for the assumptions specific to this tool. The methodology page explains conventions shared across calculators, and U.S. Department of Defense: retirement systems is the reference for any time-sensitive statutory or product rule mentioned here.
What does the Military Retirement Calculator result include?+
The result focuses on estimated monthly retired pay, annual retired pay and the multiplier used. It is calculated from the inputs shown on this page rather than from live account, market or government data. Read the formula and limitations section before transferring the result into another planning tool.
What should I change when testing another Military Retirement Calculator scenario?+
Change one major assumption at a time so you can see what drives the result. Useful inputs to test include Monthly retired-pay base, Years of service, Retirement system. Use a conservative case alongside your central estimate rather than relying on only the most favorable combination.
Can the Military Retirement Calculator replace an official statement or professional advice?+
No. It is a planning calculator. Military retirement can depend on service entry date, disability, high-3 calculations, REDUX/CSB, reserve points and other rules. Confirm the official calculation for your status. Use official statements and current rules when an exact legal, tax, pension or account figure is required.
