FAQ
What is compound interest?
Compound interest is interest calculated on both the initial principal and accumulated interest. It grows exponentially over time.
How does compound frequency affect returns?
More frequent compounding (monthly > quarterly > yearly) means interest is reinvested more often, resulting in higher total returns.
