Nationwide, more than $244 billion is invested in almost 12 million state-administered 529 plans, an increasingly popular savings vehicle for families, according to a report released this fall by the College Savings Plans Network. “We believe this is convincing evidence that 529 plans continue to be one of the most compelling ways for families of all income levels to plan ahead, save for college and reduce their reliance on student loans, which reached an all-time high of $1.2 trillion this past year,” said Betty Lochner, who chairs the network.
