This subpart regulates the basic annuity computation under the Federal Employees Retirement System (FERS).

In this subpart—

Full-time service means service performed by an employee who has—

(1) An officially established recurring basic workweek consisting of 40 hours within the employee's administrative workweek (as established under § 610.111 of this chapter or similar authority);

(2) An officially established recurring basic work requirement of 80 hours per biweekly pay period (as established for employees with a flexible or compressed work schedule under 5 U.S.C. chapter 61, subchapter II, or similar authority);

(3) For a firefighter covered by 5 U.S.C. 5545b(b) who does not have a 40-hour basic workweek, a regular tour of duty averaging at least 106 hours per biweekly pay period; or

(4) A work schedule that is considered to be full-time by express provision of law, including a work schedule established for certain nurses under 38 U.S.C. 7456 or 7456A that is considered by law to be a full-time schedule for all purposes.

Part-time service means any actual service performed on a less than full-time basis, by an individual whose appointment describes a regularly scheduled tour of duty, and any period of time credited as nonpay status time under 5 U.S.C 8411(d), that follows a period of part-time service without any intervening period of actual service other than part-time service.

Proration factor means a fraction expressed as a percentage rounded to the nearest percent. The numerator is the sum of the number of hours the employee actually worked during part-time service; and the denominator is the sum of the number of hours that a full-time employee would be scheduled to work during the same period of service included in the numerator. If an employee has creditable service in addition to part-time service, such service must be included in the numerator and denominator of the fraction.

Total service means the full years and twelfth parts thereof of an employee's or Member's service creditable under subpart C of this part, excluding any fractional part of a month.

(a) Except as provided in paragraph (b) of this section and §§ 842.405 and 842.406, the annuity of an employee or Member is 1 percent of average pay multiplied by total service.

(b) The annuity of an employee is 1.1 percent of average pay multiplied by total service, provided the individual—

(1) Has completed 20 years of service; and

(2) At the time of separation on which entitlement to an annuity is based—

(i) Is at least age 62; and

(ii) Is not a customs and border protection officer, a Member, Congressional employee, military reserve technician, law enforcement officer, firefighter, nuclear materials courier, or air traffic controller.

The annuity of an employee or Member retiring under § 842.204(a)(1) or § 842.212(b) is reduced by five-twelfths of 1 percent for each full month by which the commencing date of annuity precedes the 62nd birthday of the employee or Member, unless the individual—

(a) Has completed 30 years of service; or

(b)(1) Has completed 20 years of service; and

(2) Is at least age 60 on the commencing date of annuity; or

(c) Has completed 20 years of service as—

(1) An air traffic controller, except one separated by removal for cause on charges of misconduct or delinquency;

(2) A firefighter and/or law enforcement officer, except one separated by removal for cause on charges of misconduct of delinquency; or

(3) A Member, except one separated by resignation or expulsion.

The annuity of an air traffic controller retiring under § 842.207 or a law enforcement officer, firefighter or nuclear materials courier retiring under § 842.208 is—

(a) One and seven-tenths percent of average pay multiplied by 20 years; plus

(b) One percent of average pay multiplied by the years of service exceeding 20 years.

(a) The annuity of a congressional employee or Member who is first covered by FERS on or before December 31, 2012, and who has had at least 5 years of service as a congressional employee, Member, or any combination thereof totaling 5 years is—

(1) One and seven-tenths percent of average pay multiplied by the total number of years of service as a Member and/or congressional employee not exceeding 20 years; plus

(2) One percent of average pay multiplied by the years of service other than that of a Member and/or congressional employee.

(b) Except as provided in paragraph (c) of this section, the annuity of a congressional employee or Member who is first covered by FERS after December 31, 2012, or Member re-elected with less than 5 years of FERS service after December 31, 2012, and who has had at least 5 years of service as a congressional employee, Member, or any combination thereof totaling 5 years is 1 percent of average pay multiplied by total service.

(c) The annuity of a congressional employee or Member is 1.1 percent of average pay multiplied by total service, provided the congressional employee or Member—

(1) Has completed 20 years of service; and

(2) Is at least age 62 at the time of separation on which entitlement to an annuity is based.

The annuity of an employee whose service includes part-time service is computed in accordance with § 842.403, using the average pay based on the annual rate of basic pay for full-time service. This amount is then multiplied by the proration factor. The result is the annual rate of annuity before reductions for retirement before age 62, survivor benefits, or the reduction for an alternative form of annuity required by § 842.706.
