38 C.F.R. § 21.5742
(a) Educational assistance. A veteran or servicemember shall be entitled to one standard academic year (or the equivalent) of educational assistance for each year of service following the first enlistment beginning after November 30, 1980 (up to a maximum of four years). If the veteran or servicemember completes two years of active duty in the term of enlistment, but fails to complete the enlistment or fails to complete four years of active duty in an enlistment of more than four years, his or her entitlement to educational assistance shall be calculated as follows:
(5) VA shall multiply the number of total months in paragraph (a)(4) of this section by 75.
(Authority: 10 U.S.C. 2142(a)(2))
(b) Subsistence allowance. A veteran or servicemember shall be entitled to nine months of subsistence allowance for each standard academic year of entitlement to educational assistance. For each period of entitlement to educational assistance which is shorter than a standard academic year, a veteran or servicemember will be entitled to one month of subsistence allowance for each month of entitlement to educational assistance. This entitlement shall not exceed nine months.
(Authority: 10 U.S.C. 2144)
