Frequently Asked Questions
What is compound interest?
Compound interest is interest calculated on the initial principal plus all accumulated interest from previous periods. It grows faster than simple interest because you earn interest on your interest.
How does compounding frequency affect returns?
More frequent compounding (daily vs. annually) yields slightly higher returns because interest is added to the principal more often. The difference becomes more significant over longer time periods.
