Select Retirement System
The selected system changes the calculation multiplier and retired pay base rule.
Eligibility Note: Not all service members are eligible for every system. Eligibility is governed by your Date of Initial Entry to Military Service (DIEMS). Service members cannot arbitrarily select a system; High-3 generally covers those who entered before 2018 who did not opt into BRS, while BRS covers all personnel entering since 2018.
Service & Pay Details
Total service applied: 20.00 creditable years (20 yrs, 0 mos).
Your current monthly base pay based on rank and pay grade.
Official High-3 / BRS retirement pay is calculated from the average of your highest 36 months of basic pay (typically the last 3 years of service), not just your final single month pay.
Estimated Military Retirement Pay
Step-by-Step Calculation
20 years + (0 months ÷ 12) = 20.0000 years
20.00 years × 2.5% (High-3 (High-36) multiplier rate) = 50.00%
Highest 36-Month Average Basic Pay (High-36 Base) = $6,200.00
$6,200.00 × 50.00% = $3,100.00 / month
$3,100.00 × 12 months = $37,200.00 / year

This calculator provides estimates for planning purposes only. Actual military retired pay and eligibility depend on your service history, retirement system, pay records, and applicable laws and regulations. Verify your estimate with official military personnel/pay resources.
Note on Assumptions: Please note that all calculations on this tool are estimates and planning assumptions based on standard non-disability active duty formulas. The final and legally binding retirement determination, creditable service verification, and pension disbursements are performed exclusively by authorized official military channels — including the Defense Finance and Accounting Service (DFAS), the U.S. Coast Guard Pay & Personnel Center (PPC), and your respective service branch personnel command.
What is Military Retirement Calculator?
The Military Retirement Calculator is a planning utility for U.S. service members across all branches—Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard—to estimate monthly and annual retirement pension pay under Final Pay, High-3 (High-36), and the Blended Retirement System (BRS).
How it works?
Choose your retirement system, enter creditable service years and months, and input your current or highest 36-month average basic pay. The calculator applies the official multiplier formula (2.5% per year for Final Pay and High-3, 2.0% per year for BRS) with exact fractional service credit. You can also model Cost-of-Living Adjustments (COLA) over 5 to 20 years and compare career scenarios side-by-side.
