Frequently asked questions
What is the difference between simple and compound interest?
Simple interest is earned only on the principal. Compound interest is also earned on interest already added, so it grows faster over time.
Does more frequent compounding make a big difference?
It increases returns slightly. The rate and time period matter far more than compounding frequency.
