Get to know your Defined Benefit Supplement: Part 1, Overview
Your Defined Benefit Supplement Program account is a savings account you have in addition to your Defined Benefit Program account.
It provides another source of guaranteed income when you retire in addition to your main CalSTRS monthly retirement benefit. If you take on extra pay assignments like coaching or club advisor, your contributions will fund this account.
