Q1: What counts toward my high-3 salary?
A: Your basic pay (before deductions) for any 3 consecutive years of highest earnings, including locality pay but not bonuses or overtime.
Q2: Can I include part-time service?
A: Yes, but part-time service is prorated based on hours worked compared to full-time.
Q3: What if I retire before age 62?
A: The standard 1% multiplier applies unless you have 20+ years of service and retire at age 62 or older.
Q4: Are there reductions for early retirement?
A: Yes, if you retire under the MRA+10 provision (Minimum Retirement Age with 10-30 years of service), your pension is reduced by 5% per year under age 62.
Q5: How is the pension paid out?
A: As a monthly annuity for life, with options for survivor benefits that may reduce the amount.
