Calculate Your Federal

According to OPM guidelines, your FERS annuity is calculated using the formula: Years of Creditable Service × High-3 Average Salary × Multiplier. The standard multiplier is 1% for most employees. If you retire at age 62 or older with at least 20 years of service, the multiplier increases to 1.1%. Special category employees (law enforcement officers, firefighters, and air traffic controllers) receive a 1.7% multiplier for their first 20 years of service and 1% thereafter. Your creditable service includes all periods of federal employment covered by FERS, plus unused sick leave credit (which is added to your service time for annuity computation purposes).

Unused sick leave is converted into creditable service for your FERS annuity calculation. The conversion depends on when you retire and how much sick leave you have. For retirements after 2014, all unused sick leave counts toward your annuity (previously, only 50% counted for FERS employees). The leave balance is converted into months and days of service credit, which is then added to your total creditable service before applying the FERS formula. For example, if you have 2,000 hours of unused sick leave, that converts to approximately one year of additional service credit. This can significantly increase your annuity — in many cases by several hundred dollars per month.

The enhanced 1.1% multiplier is available if you retire at age 62 or older with at least 20 years of creditable service. This represents a 10% increase over the standard 1% multiplier. For example, with a high-3 salary of $100,000 and 25 years of service, the standard formula gives you $25,000/year (25 × $100,000 × 1%), but with the 1.1% multiplier you receive $27,500/year (25 × $100,000 × 1.1%) — an extra $2,500 annually. To qualify, you must actually be age 62 when you retire, not just meet Minimum Retirement Age. Employees who retire before 62 receive the standard 1% multiplier even if they eventually turn 62.

The FERS survivor benefit provides ongoing income to your spouse after your death, but it reduces your annuity during your lifetime. You have three options: Full survivor benefit (your spouse receives 50% of your annuity, costs you 10% of your annuity), Partial survivor benefit (spouse receives 25%, costs you 5%), or No survivor benefit (maximum pension for you, but nothing for your spouse). For example, if your calculated annuity is $30,000/year and you elect the full survivor benefit, you'll receive $27,000/year ($30,000 - 10%), and your spouse will receive $15,000/year (50% of the unreduced amount) after your death. The decision depends on your spouse's other income sources, health, and age difference.

The high-3 is your highest average basic pay earned during any consecutive 36-month period of service. It typically includes your base salary but does NOT include overtime, bonuses, locality pay adjustments (for annuity purposes, though locality is part of your actual salary), or other premium pay. OPM calculates this by looking at all possible 36-month periods in your career and identifying which one yields the highest average. For most employees, this is their final three years before retirement, but if you took a lower-paying position later in your career, an earlier period might produce a higher average. Maximizing your high-3 — through promotions, step increases, or avoiding demotions near retirement — can significantly impact your lifetime annuity.
