Understanding Compound Interest
Compound interest is one of the most powerful concepts in finance, allowing your money to grow exponentially over time. Unlike simple interest, which only earns returns on your initial investment, compound interest generates returns on both your principal and the interest you've already earned. This creates a snowball effect that accelerates your wealth accumulation, making it an essential tool for retirement planning, savings goals, and investment strategies.
