10 U.S.C. § 8585: Computation of life annuity

Each civilian member who retires under section 8584 of this title is entitled to a life annuity computed by multiplying his average annual compensation during any five consecutive years of allowable service, at his option, by his number of years of service, not exceeding 35, and dividing the product by 70. The retirement annuity payable to a retired civilian member under a policy required by section 8582 of this title is counted as part of the retirement annuity provided in this section. Any difference between the amount received by the retired civilian member under his annuity policy and the total annual amount to which he is entitled under this section shall be paid to him by the Secretary of the Navy from appropriations made for this purpose. A retired civilian member of the teaching staff of the United States Naval Academy or the United States Naval Postgraduate School who retired before April 1, 1948 , is entitled to be paid, out of applicable current appropriations, $300 a year in addition to the annuity to which he is entitled under section 7085 [now 8585] of title 10. A retired civilian member whose annuity, when increased by $300 under subsection (a), is less than $1,860 is entitled to be paid an additional $300 a year out of applicable current appropriations. Additions to the annuities of retired civilian members under subsection (b) do not increase the annuities payable to the survivors of those members.” The increases provided by section 1, when added to the annuities of retired civilian members of the teaching staff of the United States Naval Academy or the United States Naval Postgraduate School, do not increase the annuities of their survivors. The annuity of any such survivor, however, who is entitled to or becomes entitled to an annuity under chapter 607 [now 857] of title 10, United States Code, shall be increased in accordance with the following schedule: “If annuity commences between— Portion of annuity not in excess of $1,500 shall be increased by— Portion of annuity in excess of $1,500 shall be increased by— per centum per centum Jan. 16, 1936 , and June 30, 1955 12 8 July 1, 1955 , and Dec. 31, 1955 10 7 Jan. 1, 1956 , and June 30, 1956 8 6 July 1, 1956 , and Dec. 31, 1956 6 4 Jan. 1, 1957 , and June 30, 1957 4 2 July 1, 1957 , and Dec. 31, 1957 2 1 Any provision of law, enacted after the effective date of this Act [ May 31, 1957 ], which increases the annuities of retired employees and their survivors who are entitled to annuities under the Civil Service Retirement Act of May 29, 1930 , as amended ( 5 U.S.C. 691 et seq.) [now covered by section 8331 et seq. 30 of Title 5], shall be applicable in like manner and to the same extent to civilian members of the teaching staff of the United States Naval Academy and of the United States Naval Postgraduate School and their survivors who are entitled to annuities under chapter 607 [now 857] of title 10, United States Code.”
