Frequently Asked Questions

What is compound interest?

Compound interest is interest calculated on the initial principal plus all accumulated interest. It grows exponentially over time — also called 'interest on interest'.

Which compounding frequency is best?

More frequent compounding (daily > monthly > quarterly > annually) yields slightly higher returns as interest compounds more often.
