Frequently Asked Questions

What is the difference between simple and compound interest?

Simple interest is calculated solely on the principal amount you initially invest. Compound interest, on the other hand, calculates interest on the principal amount and the accumulated interest of previous periods, leading to exponential growth over time.

How often is interest typically compounded?

Interest can be compounded at various frequencies, including daily, monthly, quarterly, or annually. The more frequently interest compounds, the faster your total balance will grow.
