Compound Interest Calculator — Frequently Asked Questions
What is compound interest?
Compound interest is interest calculated on the initial principal plus all accumulated interest. It causes your money to grow faster than simple interest.
How does compounding frequency affect returns?
More frequent compounding (e.g., monthly vs. annually) results in slightly higher returns because interest is added to the principal more often, earning interest on interest sooner.
