Definition
The annual window, typically in the fall, when you can choose or change employer health insurance and other workplace benefits for the coming year. Outside the window, changes generally require a qualifying life event such as marriage, a birth, or a job change.
Why it matters
Benefit elections quietly set thousands of dollars of next year's spending: premiums, deductibles, HSA and FSA contributions, and life and disability coverage. Rolling over last year's choices without checking is how families keep paying for plans that no longer fit.
Example
A couple expecting a baby compares plans during open enrollment. They move from a $200-a-month high-deductible plan to a $410 plan with a $1,500 deductible, because the delivery makes hitting the deductible near certain and the richer plan wins the worst-case math.
