Frequently Asked Questions

The basic FERS annuity is calculated as: High-3 average salary × Years of creditable service × Accrual rate (1% for regular FERS, 1.7% for special provisions). For retirements before age 62 with at least 20 years, a 5% reduction per year under 62 applies.

The High-3 average salary is the average of your highest three consecutive years of basic pay. It is used as the basis for calculating your FERS annuity.

No, this calculator provides a basic estimate without COLAs. Actual annuity may increase with inflation adjustments after retirement.
