Fers Retirement Calculator

A FERS retirement calculator helps federal employees estimate their retirement annuity under the Federal Employees Retirement System. FERS provides a three-part retirement benefit: the FERS annuity, Social Security benefits, and the Thrift Savings Plan. The annuity is calculated as a percentage of the employee’s high-3 average salary multiplied by their years of creditable federal service. For most employees, the multiplier is 1 percent per year of service, or 1.1 percent if retiring at age 62 or older with at least 20 years of service. The calculator helps employees project income at various retirement milestones.

Federal employees use FERS retirement calculators to plan their career timelines and financial futures. The Office of Personnel Management provides official tools on its website for this purpose. Inputs typically include years of service, high-3 salary, age at retirement, and TSP balance. The calculator can show how delaying retirement by even one or two years significantly increases the annual annuity. It may also estimate survivor annuity reductions and Social Security benefits at age 62, 65, or full retirement age. Understanding your FERS benefits early in your career allows for smarter TSP contribution strategies and comprehensive retirement income planning for federal government workers.
