What Is FERS Disability Retirement?
FERS Disability Retirement is a benefit for eligible federal employees who are unable to perform their job due to a medical condition. Unlike standard retirement, it requires meeting specific eligibility criteria, including:
- A minimum of 18 months of federal service
- Documentation of a disabling condition
- Inability to perform the essential duties of your position
The annuity amount depends on your High-3 average salary and total years and months of service, calculated using a formula that increases your benefits with longer service.
How the FERS Disability Calculator Works
The calculator uses the standard FERS disability formula:Monthly Annuity={High-3 Salary×Total Years of Service×0.0167High-3 Salary×Total Years of Service×0.018if service < 20 yearsif service ≥ 20 years
- High-3 Salary: The average of your highest three consecutive years of basic pay
- Years of Service: Total years and fractional months worked
The tool then provides both monthly and annual annuity estimates to help you plan effectively.
How to Use the FERS Disability Calculator
Using the FERS Disability Calculator is straightforward and user-friendly. Follow these steps:
Step 1: Enter Your High-3 Average Salary
This is the average of your highest three consecutive years of basic pay. For example:
- $75,000
- $90,000
- $120,000
The calculator will compute the average automatically if you already have it.
Step 2: Input Years of Service
Enter the total full years of federal service. Example:
- 15 years
- 22 years
Step 3: Enter Additional Months of Service
If you worked partial years, enter months (0-11). For instance:
- 6 months
- 10 months
The calculator converts these months into a decimal fraction for precise calculations.
Step 4: Click Calculate
Press the Calculate button to instantly see:
- Monthly Annuity – estimated monthly benefit
- Annual Annuity – estimated yearly benefit
The results section will appear smoothly, showing your potential income.

Example Calculation
Suppose:
- High-3 salary: $80,000
- Years of service: 18 years
- Additional months: 6 months
Step 1: Convert months to years: 6 ÷ 12 = 0.5 years
Step 2: Total service: 18 + 0.5 = 18.5 years
Step 3: Apply formula for less than 20 years:Monthly Annuity=80,000×18.5×0.0167=24,676
Annual Annuity:24,676×12=296,112
This estimate helps you understand your potential retirement income if you qualify for FERS disability.
