In the military's acronym-packed lingo, SGLI stands for "Service Members Group Life Insurance," and according to the U.S. Department of Veterans Affairs, it is a "program that provides low-cost term life insurance coverage to eligible service members."
Troops that are eligible for SGLI are active duty in any of the service branches; commissioned members of the National Oceanic and Atmospheric Administration or the U.S. Public Health Service; cadets, or midshipmen of a U.S. military academy; members, cadets, or midshipmen of an ROTC unit and engaged in authorized training or practice cruises; a member of the reserve or National Guard and are scheduled to attend a minimum of 12 periods of inactive training per year; or a service member who volunteers for mobilization in the Individual Ready Reserve.
Service members who are eligible for SGLI are automatically enrolled at the maximum rate of $400,000, though they may choose to decline or lower their coverage and make changes to it.
Service members retain their SGLI coverage for 120 days after separation from the service, though completely disabled veterans may extend that coverage for a maximum of two years after separation.
Reserve members who do not qualify for coverage are allotted "part-time" coverage.
So why do you need SGLI anyway?
Being a service member is obviously a high risk job. High risk jobs, according to CheatSheet, can cost as much as $2000 extra annually for life insurance companies, which is roughly 500 percent more than you'll pay through your SGLI.
The bottom line is that SGLI is incredibly inexpensive, at just $29 a month, and it's worth it for your family to have some peace of mind should something happen to you in the line of duty.
