Frequently Asked Questions
A CD is a time deposit offered by banks with a fixed interest rate and fixed maturity date. It typically pays higher interest than a savings account in exchange for leaving the funds untouched for the term.
More frequent compounding (e.g., daily vs. annually) results in higher effective annual yield because interest is calculated on an ever-growing principal more often.
This calculator uses the standard compound interest formula. Some CDs may have penalties for early withdrawal or variable rates, which are not accounted for here.
