An illustrative calculation. Review the assumptions below before using the result.
Basic pay, not total compensation
Multiply average monthly high-3 basic pay by years of service × 2.5% for legacy High-3 or 2% for BRS. This is regular active-duty retirement with at least 20 years; reserve points, disability, REDUX, TSP, lump-sum elections, survivor plans and future pay/COLAs are excluded.
Questions, answered.
Does this use my personal records?
No. Enter amounts or assumptions only. The site cannot retrieve an SSA earnings record, bank account, pension award or tax return.
Can I calculate with JavaScript turned off?
Yes. Each form sends a standard GET request and PHP calculates the result. JavaScript only improves the update and consent experience.
Why do the official numbers differ from my result?
Individual eligibility, exact dates, rounding, deductions and rules omitted from a simplified scenario can change the amount. Check the source and your own agency notice.
Can I print the calculation?
Use your browser’s print command. The inputs, result and assumptions remain; navigation and consent controls are removed from the printed view.
Check the sources.
