What is compound interest?

Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. It causes wealth to grow faster than simple interest.

How often should interest compound?

More frequent compounding (monthly vs annually) results in higher returns. Monthly compounding is common for savings accounts, while CDs often compound daily or monthly.
