FERS Retirement Calculator
This is an estimate, not a figure from the government. It shows a yearly pension, called an annuity, from the basic FERS formula. The real rules and figures are published by the U.S. Office of Personnel Management, which administers the plan.

How it works
The basic FERS annuity is the high-3 average salary, times years of service, times 1 percent. The rate rises to 1.1 percent for people who retire at age 62 or older with at least 20 years of service.
The result is a yearly figure, and the monthly amount is that figure divided by twelve. Other income, such as a Social Security payment or a supplement, is separate and not included.
Worked example
With a high-3 average of $95,000.00, 30 years of service and age 62, the estimated annuity is $31,350.00 a year, or $2,612.50 a month.
Questions
What is the high-3?
It is the average of your highest three consecutive years of basic pay. Your benefits statement or your agency's payroll office can confirm the figure.
Why does the tool show 1.1 percent sometimes?
The higher rate applies when you retire at age 62 or older with at least 20 years of service. Below those marks, the 1 percent rate applies.
Where can I check the real rules?
The retirement pages of the U.S. Office of Personnel Management explain the formula. Your own estimate comes from your benefits office or your retirement account.
