Understanding Compound Growth

The secret to building long-term wealth is compound interest. Compound interest occurs when you earn interest not only on your initial investment, but also on the interest that has accumulated from previous periods.

The Power of Consistency

While an initial lump sum is great, making consistent monthly contributions drastically accelerates the growth of your portfolio, especially when applied over a timeline of decades.
