Why is utilizing compound interest a powerful savings strategy?
PilotLPTM [1.2K]
When you’re younger, it’s not so much about the type of investments you hold but more about just diligently saving. “Mutual funds or stocks? It just doesn’t matter much at this stage,” says certified financial planner Janet Gray. “Simply having a savings account means you’re in the game.”

That’s because at the beginning, your savings will be the key way of growing your money. “So don’t focus on being an investment expert early on,” says investment manager Dan Bortolotti. “Focus on frugal living and adding even small amounts, like an extra $50 or more a month, to your savings. That goes a long way over time so be patient and focus on savings.” In these early years, just celebrate the fact that you actually have money and are growing your wealth in a disciplined way.  “You’re ahead of a lot of people,” says Gray.
