Frequently Asked Questions
Compound interest is when you earn interest not only on your initial investment but also on the accumulated interest from previous periods. This creates a snowball effect that can significantly grow your money over time.
The more frequently interest compounds (daily, monthly, quarterly, etc.), the more your money can grow. More frequent compounding periods result in slightly higher returns because interest is reinvested more often.
Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and accumulated interest. Compound interest leads to faster growth of your investment.
To maximize compound interest: 1) Start early to give your money more time to grow, 2) Make regular contributions, 3) Reinvest earnings instead of withdrawing them, 4) Seek investments with higher returns while considering risk, and 5) Choose more frequent compounding periods if possible.
