Who can use the Federal Ballpark E$timate?
The Federal Ballpark E$timate can be used by employees covered by the Civil Service Retirement System (CSRS), CSRS-Offset, or the Federal Employees Retirement System (FERS) who plan to retire under the voluntary age and service rules. The current version does not perform estimates for employees planning to retire under the Minimum Retirement Age (MRA) + 10 rules, or those who are covered by special computation rules such as law enforcement officers and firefighters, or former Federal employees who may be entitled to a deferred retirement.
