Economic Systems Inc. (ESI), developers of the Federal Employees Retirement Calculator, has offered the use of their application at no cost for the 2003 fiscal year. Our grateful thanks to ESI for this generous gift to our civil servants.

Welcome to FirstGov for Senior's web site for federal employees.  With this calculation model you can compute an estimate of your CSRS, CSRS Offset and FERS retirement benefits -- normal, early or disability -- as well as an estimate of your future TSP savings and Social Security benefits.

This model is designed for almost all federal employees, including those in special occupations such as law enforcement, firefighters, air traffic controllers, and those under the Congressional retirement rules.  Foreign Service is currently excluded from this calculator.

You may also compute a comparison of CSRS and FERS benefits.  Many employees don't know that when a CSRS (or CSRS Offset) employee leaves government and returns there is a 6-month window of the opportunity to elect FERS.  For detailed information to assist you in making an election decision, visit OPM's FERS Election Opportunities Home Page.

This model gives a reasonably accurate estimate of your benefits.  HOWEVER, see below if you have part-time, temporary or military service, or took a refund of your retirement contributions that you have not repaid. 

Please have the following information on hand before going to the Calculator page:

Caveats:
Extra care must be taken when entering data for part-time employment, especially with regard to the high-three. These calculations are difficult, and the instructions for them will be improved in the near future. Until then, please contact your personnel office for an accurate estimate of your high-three.
