The Survivor Benefit Plan is one of the few military benefit decisions you make once, near retirement, that keeps affecting your paycheck and your family for the rest of your life. SBP premiums come out of your retirement pay every month, whether you ever need it or not, in exchange for a promise that your spouse or dependents will keep receiving a portion of that income after you die.

It's insurance, structured through the retirement system rather than a private insurer, and like any insurance decision it comes down to weighing a known ongoing cost against an uncertain future benefit. The details of coverage, cost, and how it interacts with VA survivor benefits are where most of the real decision-making happens.
