<P> The "Buy - Up" option, also known as the "kicker", allows active duty members to forfeit up to $600 more toward their MGIB . For every dollar the service member contributes, the federal government contributes $8 . Those who forfeit the maximum ($600) will receive, upon approval, an additional $150 per month for 36 months, or a total of $5400 . This allows the veteran to receive $4,800 in additional funds ($5400 total minus the $600 contribution to receive it), but not until after leaving active duty . The additional contribution must be made while still on active duty . It is available for G.I. Bill recipients using either Ch. 30 or Ch. 1607, but cannot be extended beyond 36 months if a combination of G.I. Bill programs are used . </P> <P> MGIB benefits may be used up to 10 years from the date of last discharge or release from active duty . The 10 - year period can be extended by the amount of time a service member was prevented from training during that period because of a disability or because he / she was held by a foreign government or power . </P> <P> The 10 - year period can also be extended if one reenters active duty for 90 days or more after becoming eligible . The extension ends 10 years from the date of separation from the later period . Periods of active duty of fewer than 90 days qualify for extensions only if one was separated for one of the following: </P> <Ul> <Li> A service - connected disability </Li> <Li> A medical condition existing before active duty </Li> <Li> Hardship </Li> </Ul>
