You've heard it before but Suze Orman is telling you once again: Start investing right now.
The former CNBC host and personal finance maven barely had to think when asked about smart things 20-somethings should be doing with their cash to ensure they'll have enough later in life.
At Miami's eMerge conference in June, Orman told CNBC Make It that having a comfortable retirement at 65 is all about using compounding interest now.
"You invest money and your money makes money, and the money you made with the money that you had makes money, and everything compounds," she said.
Orman explained that if you, as a 25-year-old, put $100 each month into a Roth IRA, you could have one million dollars by retirement. But if you wait ten years to start investing, you'll end up with only $300,000. Waiting means blowing hundreds of thousands of dollars you could have made by letting that money sit and accumulate interest.
