Tiny Snowballs, Big Dollars: Mastering Compound Interest

How Kids Can Become Millionaires with the S&P 500 and Compound InterestOn Money Smart Kids, Julia and Alexia explain how a 10-year-old can nearly become a millionaire by age 40 using an S&P 500 index fund, which they describe as a “basket” of 500 major U.S. companies like Apple, Microsoft, Disney, and Amazon. They emphasize that picking one winning stock is unpredictable, so buying the basket spreads risk, and note the S&P 500 has averaged about 10% annual growth over roughly 90 years (though it varies year to year). Using compound interest and a snowball analogy, they calculate that investing $100 per week from age 10 to 40 totals $156,000 contributed and grows to about $989,000, while starting at 20 yields about $331,000, a difference of $658,000. They suggest ways kids can save and note even $20 per week could become nearly $200,000 by 40.00:00 Millionaire By Doing Nothing00:35 Meet Money Smart Kids01:21 What Is The S&P 50002:19 Why Buy The Basket03:22 Compound Interest Magic04:44 The Snowball Effect05:05 The Million Dollar Math06:58 Starting Late Costs You08:12 How Kids Can Start09:11 Your Weekly Money Mission09:38 Recap And Challenge Grownups10:19 Wrap Up And Next Episode*This is not financial advice.
