What is Compound Interest?

Compound interest means earning interest on both your original money (the principal) and on the interest that money earns. It’s often described as “interest on interest” and leads to faster growth compared to simple interest.

For example:

• Year 1: You invest $1,000 at 5% interest = $1,050.
  
• Year 2: You earn 5% on $1,050, not just $1,000.
  

Over time, this effect multiplies your returns, making early and consistent investing extremely powerful.
