Michael and Susan Dell will donate $6.25 billion to fund investment accounts for 25 million U.S. children , under a plan unveiled Tuesday. The money from their charitable funds would help to seed "Trump Accounts" ushered into law in July.

The gift would put $250 into each eligible child's account, which is meant to grow over time through investments in low-cost stock funds that track market indexes.

"The idea is to give millions of children a head start on saving for the future," Michael Dell told NPR. "And we know that when children have accounts like this, even with modest sums, they have better outcomes in life."

Michael Dell is the CEO of Dell Technologies.
