Money word

Compounding

When your growth starts earning growth of its own, snowballing over time.

Compounding is the engine behind long-term wealth: your gains earn gains, and those earn more, accelerating the longer money is left alone. Because it rewards time above all else, a child's account — with decades to run — is where compounding is at its most powerful.

Explain it to your kid

"When your money earns money, and then that money earns money too."
