The Federal Government Retirement Plan, also known as the Federal Employees Retirement System (FERS), is a retirement benefits program for federal employees. It provides three main sources of retirement income: a pension, the Thrift Savings Plan (TSP), and Social Security. The pension is a defined benefit plan, which means that the amount of the benefit is predetermined based on a formula that takes into account the employee's years of service and highest average salary. The Thrift Savings Plan (TSP) is a defined contribution plan, similar to a 401(k) in the private sector, where employees can contribute a portion of their salary and the government may also make contributions. Finally, federal employees are also eligible for Social Security benefits based on their work history. The FERS retirement plan is designed to provide federal employees with a secure and stable source of income in retirement. It's important for federal employees to understand the details of the plan and make informed decisions about their retirement savings and benefits.
