Common questions
How is the FERS pension calculated?
High-3 average salary × years of creditable service × 1%. The multiplier is 1.1% if you retire at 62 or older with at least 20 years. Law enforcement officers, firefighters and air traffic controllers get 1.7% for their first 20 years and 1% after.
What is my FERS minimum retirement age (MRA)?
55 for those born before 1948, rising in steps to 56 for those born 1953–1964, then to 57 for anyone born in 1970 or later.
What is the MRA+10 reduction?
Retiring at your MRA with 10 to 29 years of service reduces the annuity 5% for each year you're under 62, unless you have 20+ years and the annuity starts at 60 or later. You can postpone the start to reduce or avoid the reduction.
What's included in High-3?
Your highest three consecutive years of basic pay, including locality pay (or a special rate supplement). Overtime, bonuses and awards aren't included.
