The retirement age for FBI agents varies based on the agent’s years of service and their age at retirement. In general, FBI agents are eligible to retire with full benefits once they have served for 20 years and reach the age of 50, or once they have reached the age of 57 and have at least 10 years of service.

FBI agents who retire with 20 years of service and at age 50 can receive a pension that is calculated at 1.7% of their average salary over their highest three years of service for each year of service. So, an agent who retires with 20 years of service would receive a pension equal to 34% of their average salary over their highest three years of service.
FBI agents who retire after reaching age 57 and with at least 10 years of service can receive a pension that is calculated at 1% of their average salary over their highest three years of service for each year of service. So, an agent who retires with 20 years of service would receive a pension equal to 20% of their average salary over their highest three years of service.
However, it’s worth noting that some FBI agents choose to continue working beyond their retirement eligibility. This can be done through a program called the Senior Executive Service (SES), which allows experienced agents to continue working in a limited capacity for up to five years after retirement eligibility.
In addition, some FBI agents may choose to retire earlier or later than the standard retirement ages based on personal preferences or individual circumstances. Overall, the retirement age for FBI agents varies based on a range of factors, and retirement benefits are based on an agent’s years of service and other factors.
