High-3 Salary Calculator
Calculate your highest 36 consecutive months of basic pay - the key number used to determine your FERS retirement pension.
What is High-3?
Your "high-3" average salary is the average of your highest 36 consecutive months of basic pay. This amount is used to calculate your FERS retirement annuity.
Note: Only basic pay counts toward high-3. Overtime, bonuses, awards, and locality pay adjustments do not count (though locality-adjusted salaries are your basic pay for calculation purposes).

Understanding Your High-3
- • Your high-3 doesn't have to be your most recent 3 years - it's the highest consecutive 36 months
- • Basic pay includes your grade/step salary plus locality pay adjustment
- • Overtime, bonuses, awards, and other premium pay do not count toward high-3
- • If you had a promotion or step increase, the higher salary months will likely be in your high-3
- • OPM uses your official personnel records - this calculator is for estimation only
