| From: | To: |
The FERS (Federal Employees Retirement System) annuity calculation determines the annual pension benefit for eligible federal employees based on years of service and high-3 average salary. This basic formula provides the foundation for retirement benefits under the FERS system.
The calculator uses the FERS annuity formula:
Where:
Explanation: The formula calculates 1% of the high-3 average salary multiplied by years of service. For employees with 20+ years of service at age 62 or older, the multiplier increases to 1.1%.
Details: Accurate annuity calculation is essential for federal employees to plan their retirement, understand their expected pension benefits, and make informed decisions about retirement timing and financial planning.
Tips: Enter total years of federal service (including partial years) and the high-3 average salary in USD. Both values must be positive numbers for accurate calculation.
Q1: What is included in the high-3 average salary?
A: The high-3 average includes basic pay from your highest 3 consecutive years of federal service. It does not include bonuses, overtime, or allowances.
Q2: How are partial years of service calculated?
A: Partial years are converted to decimal (e.g., 6 months = 0.5 years). The calculator accepts decimal values for precise calculations.
Q3: Are there different multipliers for special circumstances?
A: Yes, employees with 20+ years of service who retire at age 62 or older use a 1.1% multiplier instead of 1%.
Q4: What other factors affect FERS retirement?
A: Additional factors include Social Security benefits, Thrift Savings Plan, retirement age, and special provisions for law enforcement officers and firefighters.
Q5: Is this calculator suitable for CSRS employees?
A: No, this calculator is specifically for FERS employees. CSRS has different calculation rules and multipliers.
