Open a high-yield savings or investment account and put compound interest to work. No minimum balance required.
Compound interest is interest earned on both the initial principal and previously accumulated interest. Unlike simple interest, it grows exponentially over time.
More frequent compounding (daily vs annually) results in slightly more growth because interest is calculated and added to the principal more often, creating more opportunities for interest-on-interest.
The Rule of 72 estimates how long it takes to double your money: divide 72 by your annual interest rate. At 8% interest, it takes approximately 72/8 = 9 years to double.
