1. What is the OPM Retirement Annuity Calculation?

The OPM (Office of Personnel Management) retirement annuity calculation determines the annual retirement benefit for federal employees based on their salary, years of service, and a specific multiplier percentage.

2. How Does the Calculator Work?

The calculator uses the OPM annuity formula:

Where:

• \( Salary \) — Annual salary in USD
• \( Multiplier \) — Percentage multiplier (e.g., 1.0 for 1%)
• \( Years \) — Years of service

Explanation: The formula calculates the annual retirement benefit by multiplying the salary by the multiplier percentage and years of service, then dividing by 70.

3. Importance of Annuity Calculation

Details: Accurate annuity calculation is crucial for federal employees to plan their retirement income, understand their benefits, and make informed decisions about retirement timing.

4. Using the Calculator

Tips: Enter salary in USD, multiplier as a percentage (e.g., enter 1 for 1%), and years of service. All values must be valid positive numbers.
