Frequently asked questions
What is a certificate of deposit?
A CD is a savings product that locks your money for a fixed term at a fixed APY. You usually cannot withdraw early without a penalty.
Why does this use the APY directly?
APY already reflects compounding for the year, so the maturity value is the deposit grown by the APY once per year for the term.
