All calculations are estimates and should not be considered financial advice.

Compound interest means you earn returns not just on your original investment, but also on the accumulated interest over time
Tax-deferred accounts like IRAs and 401(k)s maximize the compounding effect since you don’t pay taxes on gains until withdrawal
Note: The average annual stock market return over the past 100+ years has been around 10%, though actual returns vary by investment type, market conditions, and time period (*** past returns do not guarantee future performance ***)
