1. What is the Illinois DOI Pension Formula?

The Illinois Department of Insurance (DOI) pension formula calculates the annual pension benefit based on years of service and final average compensation. This formula is commonly used for certain public employee retirement systems in Illinois.

2. How Does the Calculator Work?

The calculator uses the Illinois DOI pension formula:

Where:

• \( YS \) — Years of Service (years)
• \( FAC \) — Final Average Compensation (USD)
• \( 2.5\% \) — Annual multiplier factor

Explanation: The formula multiplies 2.5% by the total years of service and the final average compensation to determine the annual pension amount.

3. Importance of Pension Calculation

Details: Accurate pension calculation is essential for retirement planning, financial security assessment, and understanding retirement benefits for Illinois public employees.

4. Using the Calculator

Tips: Enter years of service as a decimal number (e.g., 25.5 years) and final average compensation in USD. Both values must be positive numbers.
