Compound interest is often called the eighth wonder of the world — and for good reason. Unlike simple interest (which only earns on the principal), compound interest earns on both the principal AND the accumulated interest, creating exponential growth over time.
More frequent compounding means slightly higher returns. $10,000 at 5% for 10 years: annual compounding = $16,289; monthly = $16,470; daily = $16,487. The difference grows larger with higher rates and longer timeframes.
