Perguntas Frequentes (FAQ)

Why did Albert Einstein call compound interest the 8th wonder of the world?

Because interest earned on principal is added back into your capital to earn further interest in subsequent periods, creating exponential wealth growth over time.

How does compounding frequency impact returns?

More frequent compounding (e.g., monthly vs. annually) causes interest to compound faster, resulting in slightly higher effective annual yields.
